Here’s an interesting project the Chipper – ATtiny Programming and Prototyping Shield built by Ben Rothschild: As a high school senior and electronic enthusiast, I recently built a programming shield for 10 different types of ATtiny chips that can be used with either an AVR programmer or Arduino Board. Some of the features on the […]

DIY programming pen
Anthony documented his programming pen build: One minor annoyance when programming microcontrollers in-circuit, is that often quite a bit of PCB space is lost due to the programming connector. Furthermore, when you have to program many chips, repeatedly reconnecting the programming cable quickly becomes a chore. So when I found an article about constructing a […]
DIY laser cutter for PCB stencils
HardwareBreakout shared a tutorial on how to make your own laser cutter for cutting PCB stencils: Are you sick and tired of using a tooth pick to apply solder paste? Are you still using through hole components because you don’t want to deal with soldering surface mount devices (SMD)? If so, this post provides you […]
DIY hamster wheel using an old hard disk drive
Can’t sleep because of a noisy hamster wheel? Felipe shows you how to easily make a very silent homemade hamster wheel using an old hard disk drive: Felipe La Rotta from Cocodrilabs had a noisy hamster wheel. Hamster wheels like most other mass produced pet items are made as cheap as possible, that means that you […]
DIY corflute project enclosure
Sleemanj posted pictures of his simple DIY case from a corflute: So I wanted to put one of my handy dandy LM2577 DC-DC SEPIC’s in a box with some binding posts. Being of an incredibly cheap-ass nature genetically there is no way I’m shelling out for an actual project box if I can avoid it! […]
LED Matrix link
MobileWill built this LED Matrix link project for his wedding: i just wanted to share my latest project for my wedding but i have also listed on tindie. I made a easy way to use the led matrix with the max7219. They are daisy chainable and i will be making a microcontroller add on as well. […]
Superprobe meets vintage multimeter
Mountaindude writes: “Built myself a Super Probe, in part based on DP’s design, parts from the original design. Nice little project, all in all”: It’s really just a Superprobe in a somewhat unique (probably not, but I like the concept..) case. The Superprobe exists in various flavours, the ones I’ve liked best so far are […]
Digital counter with internal PIC EEPROM memory
Electropepper documented his small SMD digital counter build: This is a simple digital counter with a serial rs-232 and a 7 segment display, i started this project to count items on some shelfs, but it can be used for anything, it is also, for the exception of the connectors, completely on SMD components. The circuit is […]
Minecraft cube
Ryandiver shared his minecraft cube project in the forum: After my flowers went down a treat on Valentines Day I decided that I needed another project. A friends birthday is in April, so I figured that would be enough time to build something. While reading my usual news stuff I came across this and thought it […]
Making MIDI hi-hat controller from unused bass drum pedal
Hwmayer documented his DIY MIDI hi-hat controller from unused bass drum pedal: Recently one of my friends bought an electronic drum set made by polish manufacturer “DIG DRUM”. The drum set is very good and combined with the Alesis triggerIO works really well. Unfortunately the pedal for controlling the hi-hat open/close signal was not included […]
Big 7-segment countdown timer
Paul over at Dorkbotpdx has written an article about his 7-segment countdown timer: The main challenge was driving the LEDs with a constant current, because they need about 10.5 volts across the several series LEDs. I wanted to run from 12 volts, so there wasn’t much voltage left over for the normal current limiting resistors. […]
Introduction to home automation
Introduction to home automation: We have all see some complex home automation systems, this video made by Jeremy from The Custom Geek gives a good overview of what is involved behind the scenes. This system lives in the garage and interfaces audio, video, phone, intercom, lighting and alarm system. Since the system is all connected […]
DIY soldering station test
dtmf did some tests for his DIY soldering station. Check out the video after the break. Via the forum.
Constant current dummy load in an HDD cooler
Kerry Wong built this DIY dummy load in a hard drive cooler aluminum case: Basic constant current dummy load using an Op Amp and a by-passing MOSFET is very easy to build and had been made quite popular following Dave’s video on EEVBlog. I happened to have an old aluminum hard disk cooler case collecting dust. […]
Improve wireless doorbell
Trandi posted a step by step guide of his DIY wireless doorbell build: So this was the perfect pretext for a small electronics project, centred around the idea of a simple voltmeter that would notify us when the voltage goes below a safe level. This would most easily be done with a small micro controller […]
GPS to SD card data logger and compass
Want to keep track of your trips from anywhere you are? Here’s a DIY GPS to SD-card data logger/compass by Ktulu: Earlier this year I have bought on the flea market a used car GPS system, an Amstrad gp1000. (Un)fortunately it was so badly damaged, that it could not be repaired, so I thought I would […]
DIY PicKit2 clone
Drjeseuss built a PicKit2 clone: After completing the build, I programmed the PIC18F2550 with the PicKit2 firmware using a JDM pin wiggler. I connected to the PicKit2 Clone using both the MPLab IDE, and the dedicated PicKit2 application. Both connected to the unit properly. I loaded up the bootloader hex for the BPv4.0c. I then […]
TOP242 power source for 10W LEDs
Mincior over at Electroni-city built this DIY TOP242 power source for 10W LEDs : Inside the case of a regular wall charger with a 500mA transformer I’ve built a source in commutation for powering 10W LEDs by using a TOP242 integrated circuit in the primary part and the LM393 dual comparator on low voltage.
DIY USB power strip
Kenneth Finnegan posted his DIY USB power strip build: In any case, now I’m down my most-used USB charging port, and a Chumby. I considered simply replacing the power supply and carrying on, but having a few more bed-side USB ports would be handy. I therefore opted to build myself a USB power strip.
Bluetooth network monitor shows you stats
This bluetooth network monitoring device by Zak Kemble shows network statistics on a small LCD screen: Whenever I want to see why a download is going a little slow or getting lag on an online game I’d have to log in to my routers web page or SSH in to see if its someone else in the […]
