Omnivision OV9650 Breakout
Mux blogged about his breakout for the OV9650, all files are available here: I made this breakout for the OV9650 a while ago, and I’ve been waiting to test it before sharing, I finally had the chance to do so, I used an FPGA this time for testing, and here’s the result. The breakout has two SOT23 […]
DIY NAND Flash reader
SpriteMods has published their design for a DIY NAND flash reader. When security-testing the ‘secure’ USB-sticks I got my hands on in the past, I needed a way to directly read the NAND-flash these sticks use to store the data on. For that, I created a quick hack: a NAND-reader consisting of a small PCB […]
EGYDuino – Arduino compatible board
Dr. Ayman Shalaby over at Electronics Lab has posted an article describing EGYDuino, an Arduino compatible board that can be build using home process: EGYDuino is a DIY Arduino clone made on a single sided PCB board. It’s simple and cheap to build using home PCB fabrication methods and it’s 100% compatible with Arduino.
The easy peasy stepper driver/stepper motor test circuit
Rohit Gupta writes: I made a very easy to make stepper driver and motor tester that could be useful to people working with steppers for 3D printers or CNC. I saw an article a while back here on DP and HackADay itself that used a controller (ATiny45 i guess). I thought it would be useful […]
Chipstomp assembly – Digital side
Here’s Catmacey’s digital side of the Chipstomp. He wrote a post on his blog detailing its assembly: I started with the digital side of things. The first task being to get the PIC and it’s supporting circuitry up and running and confirm that all was ok by attempting to talk to it with my PicKit […]
A computer kit from the ’70s: Ithaca Audio Z80 CPU card for the S100 bus
Fabio Battaglia blogged about his Ithaca Audio Z80 CPU card for the S100 bus project: First of all, I assembled some simple test code to write a letter on my video console, just to check that code was actually executing. Obviously I only got a black screen at first, which seems a constant when I build […]

FPGA based PlayStation portable display driver
Kalle Hyvönen has designed a FPGA-based display driver for driving PlayStation Portable displays: This is a project I made quite a while back (about 7 months ago). I wanted a bigger display for a project of mine and noticed that PlayStation Portable displays (480×272 pixels) are quite cheap on eBay but they do not have […]
NOT-A-CAMERA, the 2D camera that shoots JPGs and HD video
Olivia Barr writes about her latest project, the NOT-A-CAMERA: Introducing my latest creation, the NOT-A-CAMERA! It’s a REAL camera designed to look like a fake 2D camera etched into wood that shoots HD video and 3.5mb jpgs. Yep, it’s a functional camera, a spy camera laser cut in solid walnut and only half an inch thick. There is […]
Why we need a CNC pick-n-place
Chris Holden of Nerd Club has been working on a CNC pick-n-place machine and wrote a post on his blog detailing it’s assembly: Hand-soldering SMT components is slow going. And almost an hour per board section is pretty woeful. So it’s time to start seriously thinking about this CNC pick-n-place machine. Steve is going to go beserk. I […]
Serial audio player with amplifier
Chris Holden writes: Steve Carpenter wants some wav playing boards, so I redesigned the circuit to use an integrated op-amp, so they just require power and a speaker. I’ve no idea which op-amp works best, a TL072 or an LM386 (I’ve not had much luck with the LM386 in the past, and Steve really rates […]
Thermal camera project
In this video Avery demonstrates his thermal camera project that he is working on: The code does technically work. I put my hand over the sensor, and LEDs light up. In the video, they appear to get brighter because the led on/off decision is made by basically taking the image and converting it to on/off based […]
