Been a while since I’ve done one of these. You may remember in the last part of this series of articles, I hinted at a documentary I was doing (It’s posted below, but you can check it out here if you don’t want to wait). This was April, seven whole months ago.
I got busy. That happens with life and I wish it didn’t. On top of that, my computer couldn’t handle the high definition video that I wanted it to. I wish it could have, but it couldn’t.
The documentary in question is about my friend and his barn. For a little background, he lives in a house that was built around the time of the American Civil War, and the property also includes a barn from the same era. Back then, my whole town was farm land (apparently my property 30 seconds away was part of an orchard) but now the original properties have been substantially broken down for housing. From what I’ve seen, his is the only one in town to include the original barn. Anyway, I called him up and asked him if he’d be interested in letting me do some filming to test out my camera. He agreed.
Now, it’s important to note that this filming had no plan. I came over and told him to just start talking. We didn’t hash out too much of a story, there wasn’t any logic to the way the footage was shot, and we concluded filming when there wasn’t enough light to go any further. Having said that, don’t expect the resulting documentary to follow any logical flow. It was more an act of shooting as much as possible, and then seeing if I could somehow work all the footage together in a way that made sense. In this regard, I think it came out well.
Let’s talk about where I messed up. For one, lighting. I brought a measly halogen light when I went to film, but quickly abandoned it. It made absolutely no difference whatsoever in illuminating the room. I probably could have produced better footage had I handled the ISO settings better, so that’s something to take into consideration for next time. Really though, it’s difficult to get a good sense of things when you have only a two inch screen to look at and adjust with. On top of this, I also purchased an inexpensive NEEWER LED lighting rig that sits on top of the camera. Though off-brand and cheap, it’s particularly bright and comes with several gels so it should help out tremendously. A smaller mistake I made was where I had my friend looking when on camera. While I tried to follow the rule of thirds as best as I could, I didn’t know about having the subject look to the far side of the camera. If you have him look at the edge of the screen he’s on, it’s as if 2/3 of the screen is wasted. Unfortunately, it’s something that you cannot unsee after it is pointed out to you. Lastly, I had some problems in audio. While I did monitoring with headphones, it was difficult to gauge the sound quality when I could hear everything from outside the headphones as well as through them. Ultimately, I’ll probably get a pair that do noise cancellation. I’m also interested in getting an inexpensive shotgun microphone for something a little more directional.
For editing, I ended up completely building a new computer from scratch. The process and all the little details can be found here, so give that a glance if you have not already. While I did a rough edit on my laptop, it would frequently crash and I could not get an fine edit because the playback was so choppy. This new rig does the job nicely and cuts through the video like a warm knife. Now, I started editing this in Sony Vegas and that’s what I finished in. For future projects, I am hoping to switch to Adobe Premiere. I’m a bit sick of Vegas at this point, especially after finding a glitch wherein I cannot render using the beefy GPU I got for the build. Anyway, I feel the editing went well. I’m not fantastic at color correcting. I did some minor correcting and light balancing, but some of the footage was hard to do anything with since it was so dark.
Below is the final edited video if you care to check it out. I originally planned to do a few of these mini documentaries, but it took so long to do one and I ultimately ran out of time to follow through with anything else. While I had some problems with this project, I can say that few of these issues would effect how I do Obsoleet or any similar tutorial-based segment. I recently created a segment for The New Tech which will pop up soon with any hope, and I can now turn my attention more towards this type of content once again. Let’s just hope real life tones it down a little.

This article was originally written for and published at The New Tech on July 8th, 2012. It has been posted her for safe keeping.
So maybe you want to be an archivist but don’t know where to start. I don’t claim to be an expert, but I have learned a few things going down this path that I can share. Let’s break this up into two main sections: digital media and physical media. No matter what you are archiving, you should first pick out what you’re going to save. You don’t have to put too much consideration into this step. You can be passionate about a subject you wish to preserve, be helping a group of people, or doing it for the hell of it. Archiving is at it’s base both a way to ensure survival and a way to fill a hole left forgotten.
In the digital world, you’re going to be focused on downloading, storing, and uploading. Let’s start with downloading as you’re going to want to get your hands on some media. I started on a Windows computer, downloading directly with a browser. You can get your hands on some stuff simply with a DownThemAll plugin and a lot of free time. For streaming content I turn to the video downloader plugin for Firefox or Replay Media Catcher. This lets you pull videos from all your sites like Vimeo or Youtube. Sometimes things aren’t as easy as clicking a file to download it. You may have to use download sites, ftp servers, Bittorrent, or something less standard. You never know. Get to know how to use jdownloader, an ftp client like Filezilla, and a Bittorrent client like uTorrent. You might find a whole slew of content on some obscure site and you need to have the tools to dig it out. Moving on to more Unix-like systems, learn all you can about wget, curl, grep, and bash scripting. I’m not going to cover how to use all of these tools, but with a little practice there are few things you can’t get when you use them in tandem. You would be surprised how simple it is to whip up automated processes that do everything you want with just a few sophisticated commands. Also, be on the lookout for more specified tools. For example, I found a fantastic tool for downloading Youtube videos called youtubedl. If there is something out there to be downloaded, there is usually a tool for the job.
When you get the data, you’re going to need to hold it. I was originally downloading everything locally, and still like to keep local copies of data I retrieve. Always keep your data on at least two drives, and preferably buy your drives in pairs so you can easily stick with this rule. You can never have too much storage. I currently have 15TB locally just for storing archived media. When it comes to other storage mediums, I’m not easily swayed. Data tape is expensive to adopt, and cloud storage lacks stability. In earlier days, I had only an 80GB drive, so I would back up to DVD+Rs. A lot of people will tell you that your burned media will go bad after about 6-10 years, but I have yet to have a disc become unreadable. I will say that I’ve had a lot of luck with Verbatim discs. I would coaster many discs by other brands when burning, but have only ever had one Verbatim fail on me. Stick with what your budget is, the price of hard drives are only going down, but if you’re a kid on a budget a spindle of DVDs can help in a pinch. Also, keep an eye on solid state drives. While I have yet to adopt them, they are the new thing in mass storage, though the price is still a bit steep.
So now you want to share your data. You have many options to consider. I’ve been using The Internet Archive most recently to place files which should be saved. Depending on your content, this may not be the best option for you. A few of the techniques I mentioned before to download from can be good options for quick data dispersal. For example, setting up a torrent for your files can be done in minutes, and fast FTP/HTTP servers can be rented for however much money you want to spend. The main points here though are longevity and redundancy. You want your files up for a long time, and you want them to stay online somewhere if one server takes a tumble. While torrents alone are terrible for longevity, they are great at getting data out fast. Combine this with a server, or a data hosting/streaming service and you have some type of redundancy. Always make sure your data is accessible.
So now you might want also want to save physical media. This can be as easy or as difficult as you want it to be. Saving your physical media is best done by making it digital. The shelf life of digital data is only going up these days while physical media like paper or tape only degrades. While I’m a fan of my physical media, transferring it to a digital format is the best way to share it and keep it alive.
When dealing with publications or photographs, you can generally get good results digitizing them with a decent scanner. I happen to be a fan of Epsons, but anything around $100 these days should be able to give you decent quality scans. As always, read the reviews just to make sure. If you’re feeling a bit more crafty, you can try your hand at creating a book scanning set-up. This can easily copy all of your publications quickly. After you make your scans, you can perform any type of compression you wish, and even take the resulting image files to assemble a PDF.
Video can also be challenging to save. Whether it be VHS, Laserdisc, or even DVDs, things can get messy. When dealing with your older analog media, you can find devices to digitize them. For example, you can get a capture card like a Canopis ADVC, or any number of DVD recorders on the market. There are also a slew of other little gadgets to clean up the video along the digitizing process. After you get the video converted, you can compress the raw capture down with a codec such as h264 to make the file more manageable.
Audio can be viewed in a similar fashion to video. You can easily pipe a tape or record player into a receiver and feed the output to a nicer sound card. Here, audio can be captured using a program like Audacity and saved as a lossless file or compressed with something like Vorbis or MP3.
With something to drive you, a little know-how, and a lot of time, you can easily start archiving the media in your world. Though it may be daunting at first, you can easily build as you go. Start small, and end up saving big.

Today a show I recorded for Hacker Public Radio (hpr) has gone live on their site. It is officially titled Hacking Second Hand – Obtaining Old Tech and focuses on getting hardware from the used market. One could argue that this was a long time coming as I was asked, probably around six years ago, to record segments for TWAT which was a precursor to Hacker Public Radio. Anyway, check below for a direct link to the posting on their site!

I haven’t made a new episode in a while. I apologize for that. Let’s talk about what has happened in the interim.
Episode eight came out in February, and I released a short test video a month after with my new camera. In the month of April, I started working on a short documentary, but here is where the snags started. What it really comes down to is my computer being unable to handle editing high definition video. I edited together the footage from the first shoot after a few days, but trying to do anything more than splice clips is next to impossible. I can’t color correct without crashing, precision editing cannot be done with choppy video, and I barely have enough resources to run my editing software yet alone any other applications.
Let’s step aside from this for a minute.
In early May, I started the SaveRev3 project. I actually hinted at this in Obsoleet as an un-named project. Anyways, with the the help of others I have archived all of Revision3′s “Archived Shows” including ones they removed from their site. A nice accomplishment if you ask me. On top of this, I started a new website for the project called Anarchivism. Anarchivism is an ad-hoc/umbrella/do-ocracy destination for archiving projects which has already expanded past the Revision3 efforts to cover other video shows, audio shows, hacker conference media, and demoscene discs. With any luck, it will only get larger.
Aside from this, I have been writing more. A lot more. I have been keeping SaveRev3 status updates, general reviews, editorials, etc. and it has given a new spark to my old habits. Aside from writing for my own site, I have also been contributing articles to The New Tech, a wonderful video podcast and community-oriented site.
This leads in to what’s next. I had originally thought about releasing short one-segment videos to pass the time before I build a brand new computer with all the bells and whistles (Which I’m starting early August). Instead of doing these one-off segments for Obsoleet, I got the idea to contribute them to other shows. I am planning on creating segments for both The New Tech and BSOD in the near future before starting season 2 of Obsoleet. This way, I can still make video while getting my computer together, and have some of the editing responsibilities split with others.
I also plan on branching back out into audio. The New Tech is planning a weekly radio radio show that I hope to be involved with in some capacity. I am also planning an episode of Hacker Public Radio, which has been on the to-do list since before it was even called Hacker Public Radio (TWAT represent!). In addition to all of this, I’ve been considering revamping Techtat so that it has its own podcast in addition to the articles.
So where are we exactly with Obsoleet? Season 2 will pick up after I build an editing rig. Plain and simple. In the mean time, I’ll produce content for other shows, so you can still get your fix. As a little bonus, I’ve recently registered obsoleet.com (which I’ve been waiting to be free since starting the show) and have migrated the site over there (Update your bookmarks). It still needs some work, but it’s getting there bit by bit.
As always, let me know what you think. If you have any additional ideas, suggestions, or gripes, you know how to find me.

So before I get into talking about my next film, I’d like to do a brief writeup on some of the audio gear I’m now using. Right after I filmed my ‘Monday’ video, I was already making my plans for the next one I’d do. As soon as I moved past the conceptual ideas, there was the question of what additional hardware I might need, and it came down to a few things I wanted to pick up to handle sound better. There are quite a few people out there that embrace the built-in microphone for the T3i, but let’s just be realistic and state the obvious: it is a built-in microphone on a camera designed primarily to take stills. So you already have a camera not designed to do video, though it is capable of doing it nicely, and then you have the microphone it comes with and let’s face it, when was the last time you bragged about the microphone on your digital camera. At first I tried to be a optimistic and shot a little video indoors with me talking a few feet away from the camera. Even at a few feet, the speech was low and the background noise was high. If you consider the comment I made in the last post about filming in the wind, filming anyone talking outdoors with this setup was simply out of the question.
It came down to what combination of audio components would I want to assist my camera. If you do any sort of searching around for information about digital audio recorders, you will quickly stumble upon the company Zoom who manufacture a slew of recording products for both amateurs and professionals alike. For the DSLR filmmaker, the Zoom H1 and H4n are the popular products: the Zoom H1 being an entry level recorder with two on-board microphones, mic in and line out jacks, and the H4n boasting four channel recording and a sturdy rubberized chassis. For $300, I didn’t want to spring for the H4n, so I decided to take a gamble and try the H1 for less than a third of the price of its bigger brother. Yes, there are other digital recorders out there (Sony actually offers a similar looking recorder for about $20 less than the H1) but the reviews I looked up more than sold me on the H1, as well as hearing it do its thing.
If you do any sort of video searches for the H1 to see it in action, you may be pleasantly surprised. The recorder itself looks a bit like a toy, but the audio you can get out of it can be downright amazing at times. I quickly found videos using the H1 at a live music event and was stunned by the clarity of the recorded music. I also found another video of the H1 being compared to the internal T3i microphone and a Rode VideoMic. I have to say that to my ears, both the Rode microphone and the H1 microphones blew the T3i out of the water and the H1 very slightly outperformed the Rode mic as well. Even when they did a test of the Rode microphone plugged into the H1, I still preferred the sound of the H1 directly.
So as I said, I ordered the H1. I also got a shoe mount, since it made more sense to mount the recorder on top of my camera than to hold the recorder near it, or use a second tripod. The H1 can be screwed on to a standard tripod mount, but with a shoe mount costing under $2 I could slide one end into the slot on my camera meant for an external flash and screw the recorder onto the other. I also got a windscreen from Rode called the “Dead Kitten” which lives up to its name in appearance. Windscreens were highly recommended for the H1 which just leaves its microphones exposed with no cover. Some people say to go foam, while others will point you to the fur-styled ones. I wanted to get fur, and the two main names seem to be Rode and a smaller company called Redhead. I ended up going with Rode simply because I could get a better deal on it through Amazon. Lastly, I also ordered a 16GB microSDHC card so I could record for a long time and not have to worry about swapping cards.
Mounting the Zoom H1
When everything arrived, most things went together without a hitch. The H1 recorder has extensive settings for audio quality, and switches in the back for lo-cut, format, and automatic leveling. I switched the format to WAV and turned off automatic leveling as I have read that you will get inconsistencies: the recorder will start recording loudly and cut the sound down a few seconds in which can be nightmarish for recording music. I also pushed the quality as high as it could go, and saw that I had about 7 hours with my microSD card. Plenty of space there. The windscreen fit the recorder like a glove, but I really wonder about the blocking power in strong winds. I also noticed that it really picks up handling noise, so if you are simply hitting buttons while recording you will pick up a lot of unwanted noise. Since I am mounting this on top of my camera, there is no problem there, even with moving shots I cannot notice any movement noise. I also read wrapping the unit in some rubber bands helps, especially around the battery and card doors, and that did actually help eliminate vibrational noise to a degree. It looks a bit strange, but it works.
I’d also like to mention that while you can use the line-out on the recorder to the input on the camera, I decided for the sake of quality to record separately and synchronize the streams in post. While this may be a little more time consuming as I have to line up tracks, it should produce an overall better sound. I tried the T3i sound side by side with sound from the Zoom H1, and I have to say that I can confirm on the the fact that the H1 is much better. Even with the lo-cut filter on the H1 off, there is so much less background noise I can’t even do it justice in writing.
You’ll just have to listen to it.

So recently with doing some audio experimenting, I was introduced to the concept of binaural beats. The idea is that a listener uses a pair of stereo headphones to listen to two differen frequencies, one in each ear. The result is the perception of a beating tone as if it was produced by the brain itself. This causes brainwave synchronization with desired frequencies from outside stimuli.
So why would anyone want to do this? The practical side of this is use with learning, health, and meditation. In studies, binaural beats have been seen to increase information retention as well as the amount assimilated. Binaural beats have also been see to act as pain relief, and even help with addiction rehabilitation. Some also believe when targeting specific types of brainwaves, meditation can be enhanced as well as attribute to out of body experience and lucid dreaming.
On the other end of the spectrum, binaural beats are used as entertainment. How effectively they are used in this sense is debatable. The thought is that by manipulating brainwaves, you can temporarily change perception. So basically, binaural beats give people the ability to create audio that mimics the effects of chemical substances that alter normal body function. Enter I-Doser, probably the leading name in brainwave entertainment. Their shtick is offering up “doses” in the form of audio files that give the same effects as legal/illegal substances. However, there is much question about if they actually work or not. Many claim they do though it takes a while (which may coincide with how binaural beats are used with meditation) however a large majority of people who have had experience with I-Doser claim that either nothing happens or many people suffer the placebo effect. If you want to see for yourself, you can obtain some demos at the I-Doser website.
So of course after hearing of the concept of binaural beats, I wanted to hear binaural beats. I found an interesting program by the name of Gnaural which acts a a binaural beat generator. Its open-source and thus free, so you can try it at your liesure. Gnaural seems to be a fully functional generator with the ability to control pink noise, frequencies, etc. I tried it out and I can say it was an interesting experience, theres definately a weird feeling achieved through the sound.
So in closing, give it a whirl if you’re interested. Who knows, you may be one step closer to controlling your own dreams.

So about two weeks ago, I ordered a Stylophone from Thinkgeek and have been more than satisfied. For those that don’t know, the Stylophone was a popular toy in the late 1960′s. What sets this toy apart is that it is infact a compact synthesizer. What makes it awesome is the fact that it was used by several big names in music, for example David Bowie played a Stylophone on his song, “Space Oddity” and Kraftwerk used it on their track, “Pocket Calculator”.
I purchased a reproduction Stylophone for $20, and certainly got everything I wanted and more. The new Stylophone has three tone settings as opposed to the original Stylophone’s one, so my Stylophone has the same set of tones as the original, but also two additional. I also learned after purchasing that there is a pitch knob underneath the unit, that can be used to tune the Stylophone to the desired key, but can also be used while playing for strange melodic effects. Lastly, there is a vibrato switch on the top next to the power switch, which can make the tones “pulse” in a way that mimics the human voice.
Below is a wav file of some tones I recorded while I was screwing around with it (yeah, this thing has a line out jack).

So for the past year or so, I’ve had increased interest in vintage boomboxes. I believe the appeal comes from the need for a powerful portable audio solution. Previous to having boomboxes, I would take a set of dc-powered computer speakers, chop off the plug, strip down the wires, and hook up a set of 9-volt batteries wired in parallel. The problem with this, however, is that 9-volt batteries are expensive, and most sets of computer speakers run on more then 9 volts of electricity. So yeah, I could mix and match batteries, but to get a reliable flow of electricity, that would require casing, and basically a bunch of wiring I didn’t want to do. So I went around with underpowered speakers that just caused problems when batter life ran short.
Now, I turn to boomboxes to do the hard work for me. Boomboxes were first introduced in the mid to late 70′s and became a facet of audio gear until their decline in the late 80′s. The appeal of boomboxes were their portability, battery life, and most important, volume. Every boombox was made to be cranked up with quality amplifiers and top of the line remixing features.
The thing that makes boomboxes accessible nowadays is the fact that the majority of them included built in cassette decks. With simple adapters purchasable at any electronics store for under $15, any new mp3 or cd player can be hooked up to a boombox, giving it whole new life and purpose.
Clockwise, mid 70s Panasonic, mid 80s Soundesign, late 80s Panasonic
