Lunar Auto Repair Depends On The Sticky Stuff

lunar-rover-fender-uses-duct-tape

When you’ve got problems with your lunar rover you can’t just “trust the Midas touch”. Every unexpected repair that happens outside of the Earth’s atmosphere is a hack and it seems the common ingredient in each one is Duct tape. If you’ve seen the movie Apollo 13 you know it was used in making a square carbon dioxide filter fit into a round filter socket. [XD] let us know about another hack where NASA used Duct tape to replace a fender on the lunar rover during the Apollo 17 mission.

The rover kicks up a lot of moon dust as it cruises around on its wire tires. When a rear fender started to come loose it was secured with duct tape. We delighted in watching a moon-man tear off chunks of tape for the fix, shown in the video after the break. When the fender finally flew off of the vehicle, the engineers on the ground came up with a way to replace it using laminated maps and more duct tape.

We’ve been critical of the use of duct tape in the past. But when you’re in a bind, accept no substitutes.

Hot on the heels of our post about reading passwords from EEPROM, [n0th1n6] tipped us off about a similar hack used to resurrect an Eee PC from a bad bios flash. After discovering that a factory repair for a dead bios costs about $200, [CutenaCute_7] took on the challenge herself. She disassembled the computer and desoldered the bios chip from the board. After writing a program to flash the chip using C#, she temporarily soldered jumpers to make sure the flash worked. Looks like this is a zero cost hack, plus the time savings from not having to ship her computer somewhere. Bravo.

[Jair2k4] learned the hard way not to lend out your expensive GPS to untrustworthy people. His Garmin 200 was returned with a broken USB port and unable to charge. Luckily, all it took was some inventive thinking and he had it repaired in no time. By breaking open a Nokia cellphone car charger, he had a source of 5 volts. After that, it was only a matter of soldering the connections. However, not content with the design he pulled out a Dremel and mounted it in his 1991 Suzuki Sidekick. Quick, dirty, and actually working afterwords, just the way we like it.

Turning on your camera to this kind of black blotch will ruin your day. Cracked LCD screens have got to be the biggest digital camera killer out there. Although you can still take pictures with it, a non-functioning screen makes it difficult if not impossible to change settings and take decent photos.

[myles_h] has document the process of replacing a broken screen in his digital camera. As professional repair usually costs more than a brand new camera you’ll want to do this yourself. New screens can be purchased online, but we’ve also considered buying the same model of camera from ebay (screen intact but broken in a different way). This model, a Sony Cybershot DSC-W50, has fairly easy access to the LCD and its connection to the logic board. Before buying parts, you may want to investigate how much disassembly your camera will require.

[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.

The silicon hacker behind the Chumby, [bunnie huang], was browsing through the Mobile Phone Megamarket in Shenzhen, China and stumbled upon an unusual repair book. It turns out the book had the schematics to hundreds of Nokia phones. It’s hard to tell if they are legitimate, but the amount of information makes them seem so. [bunnie] claims that the book is a learning experience because it shows how some sub-circuits are implemented. Also, it can be a good reference for sourcing parts. Since Nokia buys millions of each component, the supply of parts they use are stable. There are also editions for other brands, such as Motorola and Samsung.

Repair A Malfunctioning LCD

June 20, 2009 by 43 Comments

When most people encounter dead pixels on an LCD text display, they figure that the display is dead and they decide to scrap it. However when the LCD display on one of [Joe]’s cordless phones started to show dead rows and columns of pixels, [Joe] decided that he could fix it. With only a pencil eraser, a hot air gun, and a screwdriver (for disassembly), [Joe] was able to fix his phone’s screen in just under 10 minutes. His process involves heating the glue holding the LCD’s ribbon cable to the phones PCB with a hot air gun and using a pencil eraser to reattach segments of the ribbon cable to the PCB. If anyone here has a problem similar to [Joe]’s, be sure to check out his detailed how-to complete with step-by-step pictures.
