It’s Friday… and you are probably are stuck at work. So why not learn how to remove a IC from a PCB — in a very very unconventional way. It’s great if you don’t care about the chip… or the board for that matter.
Seriously though, if you need to relieve some stress, the guys who made this video Electronics In a Nutshell have a very entertaining channel on YouTube where they mostly torture circuit boards and stuff in various ways. Just the way we like it.
Here’s another entertaining video to get you through the day. Lithium-Ion battery vs 220 volts.
Any fan of the DOOM series of video games remembers the BFG‘s or Big Fucking Gun. You know you wanted one, and so did Andrew. The only difference is Andrew decided to build one, and I’m guessing you didn’t.
From the beginning of Andrew’s build, it looks like your normal prop build. Start with a trip to home depot, grab some pvc pipes, solder a few leds, spray paint the whole thing, yadda yadda. But then you see towards the end of the video that Andrew put some beefy wires and a grill igniter inside… oh yeah… It’s actually a 3 chamber potato gun! And sure, you put enough fuel in it and it will do some flame thrower tricks as well.
The lighting effects by themselves look pretty good, the flash light mod, and the home-made acrylic light tubes… I bet this would keep those damn kids off my lawn!
After initially overclocking the Arduino to 32.5mhz, Mikhail started experimenting with pushing the Arduino further. First he was able to up the supply voltage to 8V and nudge it up to 37mhz. It’s a commonly known trend in the pc overclocking world that you can usually overclock further with more cooling. So without ramping up from things like water cooling, Mikhail jumps into super-cooling the Arduino with liquid nitrogen.
Liquid nitrogen is around -196 degrees Celsius. With the liquid nitrogen bath, he was able to get the Arduino running to just over 65mhz. At this point the looped test sketch running on it started failing. But before getting that far, from previous tests he ran into issues with the Arduino’s brown out detection. After replacing some of the capacitors and disabling the blown-out fuse and moving the LCD’s power supply away from the Arduino he was good to go.
You know the best part of this hack, and always my favorite is that it’s for the hell of it. This is obviously not something you would put into production or have any real application, that’s why it’s awesome.
Although not entirely practical or efficient, electro-magnetic guns are cool. And if done right, they look really neat too. This awesome gauss machine gun must be Jason’s passion, as he’s done this sorta thing before. Most of the time you will see these types of weapons in video games or sci-fi movies, maybe because it isn’t a perfected technology yet. What I find most amazing about this build is the full-auto mechanism. It’s not the speediest full auto, but is capable of 7.7 rounds a second. If you’ve ever tried to create your own auto loader system for anything like this you can appreciate this feat.
This is the kind of stuff that I really like to see. Baka Chan is my type of hacker. Here is his build log of taking the guts from a Nintendo 64, and sticking it in a Millennium Falcon. It’s not as easy as you would think, just taking the guts and tossing it in another. You have to finesse things, plan it out, and extend a lot of wiring!
So here’s the kicker. Why go through the trouble of putting the guts in a Millennium Falcon ? (Besides the obvious answer that it’s awesome). Well because you have one left over from putting a Raspberry Pi inside a N64 case of course silly! Not the cleanest stuff job I’ve seen, but it works. Bravo Baka Chan keep ‘em coming.
Joo Won Park is doing some pretty creepy noise experiments. He runs a site called 100 strange sounds and has some pretty awesome audio experiments. In this one he is using a telephone pickup device, that is converting the EMF noise into sound. Then he adds a little bit of post processing that alters pitch and envelope. The result is some pretty creepy stuff honestly.
Another cool experiment of his (that I’ve seen before) is the no-input mixer. Which is an audio mixer that is in crazy feedback mode and actually doesn’t have any input going to it. The inefficiencies of the mixer are fed back into its self looping really really fast creating noise. Then altering the mixer and knobs / sliders cause it to alter into weirder noise. I recommend checking out more of his videos, this guy has some really cool experiments going on like playing a pool noodle.
The implementation goes pretty low-tech, with wire, rubber gloves, and electrical tape. The contacts are being fed into a hacked up usb gamepad, and interpreted by a php script reading the usb port. Part of what makes this hack unique is the encoding method, which I’m sure would take some practice to get right but you have to try new stuff to push innovation, right ?
