Building Removable Epoxy Mounting Brackets

May 6, 2010 by Mike Szczys 16 Comments

[Jykazu] wanted to use an external lens with his Kodak Zi8 but he didn’t want to alter the camera or glue something onto it. His solution was to build a bracket out of epoxy dough. He first covers the camera in scotch tape to protect the finish, then he kneads the dough to mix the two parts together, using it to form the bracket that you can see above. After curing, the bracket barely sticks to the smooth tape and can be gently removed. A lens cap with a hole drilled in it is glued to this bracket and works like a charm for connecting the lens. Check out his manufacturing method in the videos after the break.

This is a great method for many applications. Last year we saw a product called Sugru which seems to be made for this type of thing but [Jykazu’s] epoxy method is just as impressive.

PC Side IM-ME Hacks

May 6, 2010 by Mike Szczys 11 Comments

[Paul Klemstine] is working on some PC-side software hacks for the IM-ME. We’ve seen a lot of hardware hacks for this device, such as controlling the display, firmware flashing, and using it as a spectrum analyzer, but if you don’t want to alter the device right away you can try [Paul’s] collection of hacks. Working with the code developed by [Ben Ryves] there is support for using the IM-ME as a command prompt, to control Win amp, and as a wireless keyboard. Crack out your C# skills and develop the next feature for this inexpensive device.

Build Your Own Wikipedia Reader

May 6, 2010 by Mike Szczys 26 Comments

One part inexpensive uC, one part touch-screen, one part Internet knowledge-base all come together to make up this Wikipedia reader. It functions in a very similar way to commercial versions by parsing XML dumps from the popular website to an SD card for use on the device. This is not limited to Wikipedia, but could just as easily be an e-reader. [Rossum] developed the package using an NXP ARM Cortex M0 model LCP1114 microcontroller. They cost just a couple of bucks but pack a 50 MHz punch with 32 KB of program memory and 8 KB of SRAM. If the nanotouch and the A VR iPhone concept didn’t convince you that [Rossum] knows what he’s doing, the video after the break of this newest creation will seal the deal.

Vehicle Information Display Hacks

May 5, 2010 by Mike Szczys 20 Comments

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 the data and sends it to a breakout board with an LCD controller on it.

To the right is a display from a Formula Student project. a Matrix Orbital GLK19264-7T-1U LCD display provides a lot of real estate for displaying data. Right now [Alan] is still in the early prototyping stages, but the video after the break demonstrates the RPM readout using a function generator. It’s not shown in the video, but he tells us that he’s since tried it out with the engine and has a PIC 16f877 reading temperate data from the electronic control transmission sensors in addition to the RPM data.

Correction: Thanks to [j] for correcting our mistake. This is a Formula Student car.

Classic Canon AE-1 Gets A Digital Upgrade

May 5, 2010 by Mike Szczys 33 Comments

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 in a digital format. What we have here is a classic camera body with a modern point-and-shoot fit inside. This seems to be a PowerShot SD 870 IS and we’d guess the original lens has been replaced with a plate of glass so as not to affect the PowerShot’s focus, and the “AE-1 Program Digital” screen is probably just an image on the memory card.

We admire the clean mod work necessary to produce this hack.

Custom PS3 Controller: Software Emulation Version

May 5, 2010 by Mike Szczys 21 Comments

[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 talk to Linux and then adjust the six-axis PS3 controller mapping accordingly.

Adding RAM To The Nexus One Without Soldering

May 5, 2010 by Mike Szczys 19 Comments

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 more ram you can just upgrade to the most recent kernel.
