Vehicle information display hacks

Posted: May 5th, 2010, 2:00pm MDT by Mike Szczys

We’ve had a few folks send us info about their vehicle display hacks after seeing [Will O'Brien's] motorcycle computer a few days ago. On the left we have a display for an electric vehicle. [S1axter] is using a 4.3″ TFT screen to display charge information for each battery cell in the car. An ATmega88 collects [...]
Mad machinist masterpieces

Posted: May 5th, 2010, 1:12pm MDT by Jakob Griffith

If a picture is worth 1000 words, by our count, [Ryan Commbes] has said 1.68×10^6 different things about his custom robot, airsoft, and monster truck builds. While we’re not ones to pick favorites, we agreed his Alpine TPG-1 (picture at the top) build is a step above the rest. Sadly, the forums with his build [...]
Classic Canon AE-1 gets a digital upgrade

Posted: May 5th, 2010, 12:00pm MDT by Mike Szczys

Shots of this Canon AE-1 camera-gone-digital have a lot of people scratching their heads. Originally there were a lot of “that’s been photoshopped” cries but the video after the break shows that it physically exists. This particular model of camera hasn’t been manufactured since 1984 so there’s little chance that the company’s bringing it back [...]
Custom PS3 controller: software emulation version

Posted: May 5th, 2010, 11:00am MDT by Mike Szczys

[Matlo] posted a tutorial that will walk you through setting up a six-axis controller emulator. In April he developed a hardware solution using the Teensy but this version just needs a Linux computer with a Bluetooth adapter. If you don’t mind adding a computer to the mix you can use any peripheral controller that will [...]
Adding RAM to the Nexus One without soldering

Posted: May 5th, 2010, 10:00am MDT by Mike Szczys

Want 21 megabytes more ram in your Nexus One? [Coolbho3000] worked out a way to tweak the kernel and remap memory usage to free up some resources. That means this comes as a custom kernel image requiring no hardware alteration. Try it out and share your experiences in the comments. But if you don’t need [...]
Possibly the most beautiful piece of hardware

Posted: May 5th, 2010, 9:00am MDT by Caleb Kraft

I’m going to break from the typical Hackaday article format for a moment. I’m smitten, captivated by this wondrous new discovery. Forgive my ignorance for having never seen one of these before, I didn’t go to school for electronics. For those, who like myself wondered, what is this beautiful glowing thing, it is a mercury arc valve [...]
When multimeters go boom

Posted: May 5th, 2010, 8:29am MDT by Caleb Kraft

Ever wondered how expensive versus cheap multimeters hold up to abuse? [Dave] gives us a pretty good idea by, well, blowing them up. He’s using a capacitor bank to put roughly 4.2 KiloVolts into the poor little meters. If you absolutely must skip to the multimeters, go to about 5:00. You really will miss out [...]
Remote operated underwater vehicle

Posted: May 5th, 2010, 7:10am MDT by Jakob Griffith

PVC hull, SLA batteries, Bilge Pumps, sounds like a good start to [Jimmy's] ROV project. Paintball gun (as a BCD), dual live cameras paired with an Arduino making it internet controlled, all tethered with a fiber optic cable, sounds like [Jimmy's] ROV got a whole lot more astounding. While some very important parts have yet [...]
