Ghetto repairs: Desoldering with a candle

Yes, that picture you are seeing is serious. [Roland] needed a chip for a damaged piece of electronics. He was lucky enough to find one on an old board at a local shop. The problem was, he didn’t have the hot air gun to remove the chip the correct way. Instead, he simply cooked the board over a candle to melt the solder. Interestingly, after he cleaned the candle-cooked board, it looked like it survived without damage. The chip worked fine and fixed his problems. Sometimes, we just don’t have the right tools for the job.

Head-mounted computer with spit, bailing wire

Oh, for crying out loud! While we were all giddy reporting on yesterday’s wonderfully done head-mounted computer, [Andrew Lim] of recombu.com comes along and essentially does the same thing with an HTC Magic handset and three dollars worth of Harbor Freight crap. Linux kernel, WiFi, accelerometer, the whole nine yards. Consider our collective ass handed to us.

Funny thing is, either of these could be considered The Consummate Hack. One flaunting the creator’s know-how with its custom-designed parts and delicate engineering, the other exhibiting a more punk flair with random scraps and off-the-shelf technology achieving much the same effect — a solution so obvious we were blind to it. Whatever your outlook, this is a great day to be a hacker!

Jump start your car with Sega parts

sega_jump_start

[Jenn's] family is a single-car household. Because of this, it’s a little more difficult to get a jump start when the headlights run down the battery. Not wanting to ask the neighbors for help, her husband [Richard] decided to come up with his own solution.

Rummaging through the parts on hand, [Richard] went with his old friend Sonic the Hedgehog. He used two 12-volt, 1 amp Sega Genesis power adapters in parallel hooked up to a 12 volt, 3 amp  power supply. The end result is a 12-volt 5 amp source hooked to the car’s electrical system and used to get their road machine started.

We have enjoyed some of [Richard's] offerings in the past, such as Super Nintoaster and the Super Genintari but this is a bit less… eloquent. A few questions do come to mind. First of all, is this the best way to use parts of your 20-year-old gaming system?  How many amps does your average car starter pull down?  And finally, what kind of issues are we looking at with the lead acid battery under these conditions?  Weigh in on the conversation in the comments.

Robert Crumb ghetto hacks

200908141259

[Robert Crumb], the celebrated artist who created the commonly recognized keep on truckin, Fritz the cat, and mr natural can be seen here doing a ghetto hack. His record was warped, so he had to melt it in the oven to flatten it out. While [R. Crumb] may not be the epitome of celebrity and wealth, he got us wondering, what celebrities do ghetto hacks? More importantly, what ghetto hacks do you continue to do, even though you could afford to just simply replace the item? In case you missed the ghetto hacks thread, here it is.

AVR RFID tag

attiny85-rfid

[pc486] sent in his hack that uses an ATtiny85 to act like an EM4102, a chip used for RFID tags. Minimally, all that is needed is the AVR and a coil, but he recommends some filtering capacitors. Depending on the size of the coil, different frequencies and ranges can be achieved. This project actually includes several hacks, such as using the coil for not only power, but a clock signal. The coil is actually able to power the chip without being connected to the power pins due to clamping diodes on the connected pins. The firmware is short but available on subversion.

Ghetto electronics repair

oven-graphics-card-nvidia

After hearing that his video card might be repairable by heating it up to reflow it, this user did just that. He stripped it down and tossed it in his oven. It’s amazing how often this type of hackish repair works. We’ve heard of people using candles on ibooks, tossing video cards in oven,s and wrapping an xbox 360 in a towel and running it for 30 minutes to get it hot enough to reflow itself. Why even bother with controlled temperatures and exact measurements? What other crazy fixes have you had to employ? We had a Playstation that only worked upside down.
