Exapod is building a line following robot based on the dsPIC33 and stuff he won from SparkFun‘s giveaways. Watch the little robot race through Monza in a video below. i’m planning of building a robot with a dspic33fj128mc804 and two … Read more
USBug is a LPC1343 breakout board with USB capability. The bootloader appears as a USB flash drive, just drag a new firmware into the drive to update. Basically, my board is a 40-pin LPC1343 breakout board with 12 MHz crystal, … Read more
Small form factor board, with a STM32L151 ARM Cortex M3 for around 5 dollars. This is the target of the MCHCK development board. The board was designed to be cheap enough so that you can develop a project with it, … Read more
Saulius writes: “I have just tested in the air my latest quadcopter telemetry link using low-cost open-source wifi board. This link can be used not only to relay telemetry data but control SU(A)V from joystick and get video back to … Read more
A while ago we wrote about using cheap Nokia 1202 LCDs for projects. These LCDs come with a solderable connector, and are easy to interface over the I2C bus. Toxic239 made a frequency counter based on the MSP430 Launchpad and … Read more
DIY Audio function generator is a low-distortion function generator which operates in the Audio frequency range. Conventional function generators use a square wave signal to generate the other waveforms like triangle, or sine wave. This approach adds noise to the … Read more
Ferdinand added a dc/dc converter circuit to the transistor tester, allowing it to be powered from 2 AA batteries instead of a single 9volt. This project is similar to our Part Ninja, it’s designed to test various electronic components like … Read more
MickM build a single layer version of the Little Wire project. He uploaded the source files for the board in the forum. Little wire is am ATtiny-based open source AVR programer that’s packed full of features: An AVR programer Four … Read more
Ezflyr’s GPS-based clock uses the GlobalSat EM-406 module to show the time with around 1 second accuracy. Here is a photo of the completed GPS Display Time Standard I intend to use for setting a variety of clock projects I’ve … Read more
Arhi is designing a 10 MHz Rubidium frequency standard output driver: Frequency standards have stable frequency output but they usually have 50 R impedance sine output with some low Vpp values (100 mV or 400 mV or in best cases … Read more
Scrawny 500mA USB charger insufficient for your hunger for power? Try this 3.6 amp USB charger based on the LM2700 boost switch-mode IC. This design is inspired by the Minty Boost but it fixes some of the issues that I … Read more
FloHimself designed and built a Little Wire AVR programmer/tool. I’ve seen this project on the frontpage and thought I’d like to tinker with this a bit. For that reason I’ve designed a simple single sided version of the board in … Read more
Chris Marion has developed an impressive and dangerous project: FireHero. It uses a complex propane system and some electric valves coupled to an Arduino controller that hooks directly into a “guitar” – a Guitar Hero input device, hence the project … Read more
In order to use even a high-priced SDR for GSM experimentation, an accurate clock source is indispensable. According to the GSM standard, a clock with “absolute accuracy better than 0.05 ppm for both RF frequency generation and clocking the timebase” … Read more
Marcus got an Atari 6502 CPU and the POKEY sound chip emulator running on a PIC32 development board. He stored around 2.5 hours of old school 8bit music in the flash. I successfully compiled the ASAP (Another Slight Atari Player) … Read more
Arup got some PCBs made by Seeed of the open-source data acquisition system he designed. The system uses solar panels, and rechargeable batteries for power. An ATmega32 microcontroller reads, and stores data onto a SD flash card. Data ca also … Read more
FRIC at ivoidwarranties has developed an Arduino addiction. So when his company needed a replacement time clock he wasn’t content to settle for a substandard commercial unit. In the true hacker spirit he designed his own superior time clock system … Read more
The FUNcube Dongle is a SDR receiver on a USB dongle which currently sells for $125 GPB. It uses the same E4000 tuner found in the $20 RTL-SDR dongle we’ve posted about previously. The developer is Howard Long, G6VLB, who … Read more
Yesterday we wrote about the QuicPSoC3 development beard for PSoC3 ICs from Cypress. You can now download the design files. Via the comments
Kartik revised his EzPSoC3 board into the new quick QuickPSoC3. These boards are mini development platforms for PSoC3 system-on-chip ICs from Cypress. Here is a list of features on the new board: Longer pads(almost 3x) so it makes soldering the … Read more
