P01-112 Powah project
Asgard posted his Powah, a little power on/off toggle with an indicator LED in the project log forum: This is a “standard” module I use for some of my other projects (see the BLiVIT thread). This version is a simple CMOS-level on/off toggle with debounce. The optional four pin positions just happen to lay […]
ULTI-ISP USB programmer for AVR & 8051
Umair Mukati wrote in to show off his project the ULTI-ISP USB key programmer which supports programming for AVR & 8051 microcontrollers: The ULTI-ISP can be used to program a wide range of AVR microcontrollers as well as 8051 series. The device can be used to read, write and erase flash memory, EEPROM, Fuse Bits. […]
DSETA board, a CPU based on the Atmel AT89C51RE2
Jechavarria has designed and built this DSETA board, a CPU based on the Atmel AT89C51RE2: In my last projects, I always use the same CPU. DSETA board, I say in the posts. Well, here it is, a CPU based on the AT89C51RE2 microcontroller from Atmel. I develop this board for some reasons. The first and […]
The 3D printer controller
Matthew of Electronics for Humans has been working on 3D printer controller: The design is based on an Atmel Atmega328 running at 8MHz (using the internal clock) at 3.3V. This is in order to keep the same voltage as the main controller board, which will be powered by the LPC1768 that only works at 3.3V […]
Workshop Update for April 10th, 2013
We’re are looking into tools for gerber paneling to further reduce the cost of prototype PCBs. We continue working on the Bus Pirate documentation, and have sent out the bill of materials for a quote. QFN breakout boards are finalized.
Erl’s voltage reference
Erl shared his voltage reference project in the forum: I had almost 6 x 6 cm left over on a 10 x 10 board I was ordering from Seeed Studios, so inspired by the Mr. Ref voltage reference project, I made something similar. It’s based on the MAX6126 2.048 V reference, uses 3 AAA […]
Introducing G400-D, the most advanced NETMF SoM yet

The SoM comes standard with Microsoft’s .NET Micro Framework (NETMF) and GHI’s premium libraries, no […]
Chipper – ATtiny programming and prototyping shield
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 […]
P01-117 Rapper project
Asgard posted his Rapper project in the forum: What this is, is a small device that records a command sequence for a TV remote control, then emits the same sequence when activated by a pulse detected in a piezo transducer. Such pulse can be as simple as rapping your knuckles on the table where the Rapper […]
