Arduino Astronomical clock for automatic light control
Here’s a project log covering the build of an Arduino Astronomical clock for automatic light control by Paulo Oliveira: My objective with this project was to build a system that, given my latitude and longitude coordinates and the current time/day of the year, automatically calculates the sunrise and sunset times, controlling the lights accordingly. There are of […]
microTone Module – Simple Analog hardware interface
Here’s an open source project the microTone Module by Dilshan Jayakody: microTone Module is analog interface to connect microcontrollers or digital logic systems with PCs. This interface use PC sound card’s audio output terminal to send commands to external hardware systems. Project’s software source codes and hardware designs are available to download at sourceforge.net.
STM32F4Stamp, a breakout board for STM32F4
Frank Zhao posted his STM32F4 breakout board in the project log forum: I really like the STM32 family of ARM microcontrollers. This breakout board is a narrow design that fits perfectly on a breadboard. Every pin is accessible. It has USB, a reset button, and a bootload button. The chip itself has a permanent USB bootloader […]
uCAN – protocol stack for microcontroller networking update
Nick Johnson over at Arachnid Labs posted an update on his uCAN- a protocol stack for microcontroller networking we posted previously: First working uCAN hardware! It’s not much to look at, but it is fully functional! A power injector with a 12v wall wart, a Raspberry Pi with uCAN expansion board, and an Arduino Uno with uCAN shield, […]

LPC812 Breakout board
cpldcpu writes: I grew fond of NXPs new LPC800 Cortex M0+ microcontrollers. I designed a small breakout for the LPC812 TSSOP20. This is the second revision. It includes push buttons for reset and activating the serial bootloader. The board has an integrated 500mA 3.3V LDO to supply both the MCU and connected devices from the […]
Mill CPU interview on Hackaday
Interview: New Mill CPU Architecture Explanation for Humans: Hackaday had an amazing opportunity to sit down with [Ivan Godard] who discussed the Mill CPU development which his company — Out of the Box Computing — has been working on for about a decade. The driving force behind Mill development is that optimizations to existing architectures […]
Bus Blaster v3 back in stock
Bus Blaster v3 JTAG debugger is back in stock at Seeed Studio.The cool thing about the Bus Blaster is that it uses a programmable logic chip as a buffer. It can imitate different types of programming hardware with a simple USB update. You can get a Bus Blaster v3 for $34.95.
Using LTC1100 as precision voltage adapter
Kerry Wong wrote about building a precision voltage adapter using LTC1100: LTC1100 is a zero-drift, precision instrumentation amplifier. Unlike LMP8358, it does not offer programmatic gain setting (the 8-pin package), and the gain is preset at 100. But LTC1100 has several advantages over LMP8358. For instance, while the typical gain non-linearity for LT1100 and LMP8358 are quite […]
Super light weight RC FPV quadcopter DIY solution
Oscar writes: The compact FPV system I have built is only about 20g, now even my mini quadcopter and micro hexacopter can carry this FPV camera and video transmitter. In this post I will share with you what are the parts you will need and how I made it.
Free PCB Sunday: Pick your PCB
We go through a lot of prototype PCBs, and end up with lots of extras that we’ll never use. Every Sunday we give away a few PCBs from one of our past or future projects, or a related prototype. Our PCBs are made through Seeed Studio’s Fusion board service. This week two random commenters will […]
Bus Pirate reference card
jrychter shared this Bus Pirate reference card he made in the forum: The Bus Pirate from Dangerous Prototypes is a really useful tool. I use it regularly to bring up and test new I2C devices, or as a cheap protocol analyzer for I2C and SPI. Unfortunately, the supplied cables aren’t clearly labeled (only color-coded), and I found the […]
Another chipKIt Motor shield, chipKIT WF 32, chipKIT DP 32, and chipKit Cmod winners
Today we announce the winners of the chipKIt Motor shield, chipKIT WF 32, chipKIT DP 32, and chipKit Cmod! There were lots of great ideas, thanks for your submissions. Congratulations to Andrew Rohne, his idea for a mobile ham radio logging system scored him a chipKIT WF 32: Since the WF32 has a built-in USB host, if I won, I’d build a […]

gcmc – G-Code Meta Compiler
Bertho has been working on a gcmc – G-Code Meta Compiler, a front-end language for generating G-code for CNC mills: I have been improving the gcmc compiler for a while and I think it is very powerful now. The grammar is done and a very rich set of built-in functions support easy creation of very complex designs. Gcmc’s […]
