The Holga is a cheap medium format film camera that has achieved cult status for its inconsistent, truly unique photographs featuring blur, light leaks, vignetting, and distortion. Poor quality digital photos aren't nearly as interesting and [Joachim Guanzon] wanted to achieve the Holga effect without using robotic Photoshop filters. He constructed this lens for his Canon 20D. The base is an EOS … [Read more...]

[Francisco] had one simple goal with this project: access every pin in the dock connector. If you want to start experimenting with the iPod this will come in very handy. Francisco has provided a PDF schematic ready to etch. I'm surprised SparkFun isn't selling something like this already. … [Read more...]

Switch mode iPod charger
April 27, 2006 By 33 Comments
Usually when someone asks me how to build a USB charger I point them to Jason Striegel's USB battery v2. It'll work for a lot of things that only need 5V. Unfortunately [ian] has a 3G firewire iPod so he decided to build a switch mode power supply to generate the 8-30V required by firewire. The device is powered by 3 AA batteries and uses a PIC 12F683 microcontroller to regulate the output … [Read more...]

Hard drive oscilloscope
April 25, 2006 By 20 Comments
[hackgadgets.com is back up... maybe][Alan] put together a list of the Top 5 Dead Hard Drive Projects. He suggested we post about the hard drive laser oscilloscope, since he couldn't find the project anywhere else. I actually saw a similar project during dorkbot-sf's presentation at Maker Faire. A laser is mounted to the drive case. The beam is bounced off of a mirror connected to the read/write … [Read more...]
Scratch built RC helicopter
April 24, 2006 By 21 Comments
Ben Hui had been planning on purchasing an RC helicopter, but with a little more reading he was determined to build his own (cache). Most of the bracketry is built out of the fiber board base used for PCBS. He has details of how he constructed the swashplate, rotor head, tail rotor, and how to make your own blades. He eventually modified a brushless CDROM motor to drive the main rotor. [thanks … [Read more...]
