Introducing the DuinoStamp (June 26, 2008)
After working in collaboration with Justin Wyatt on his idea for a stamp-sized Freeduino, I'm pleased to introduce the DuinoStamp. It's a convenient breakout board allowing you to easily embed an Arduino compatible environment into your project. The same size as a 34-pin 0.600" DIP, it's easy to incorporate into bread-boards, perf-board, or PCBs. It contains all the components and connections you need, without including costly and large extras.
Head over to it's instructions or buy one below.

New PCBs and Yellow Soldermask (May 22, 2008)
A panel with 5 fresh new products just arrived from Gold Phoenix.
Firstly a comment on the yellow solder mask: Black, Blue, and Green are my staple solder mask colours, but it's nice to branch out sometimes and I went with a yellow mask for this order. My initial impression is that it looks OK on the copper portions of the board, but the masked bare laminate is unimpressive. While it adds variety to the lineup, it definitely looks cheap compared to even the green mask (which is cheaper) and very cheap compared to a blue or black mask. I'm left with a single-sided paper-laminate feeling.
The new projects are, clockwise from the top left:
- A thermistor based high/low temperate tracker for the -5°c to 30°c range.
- A 555 based high-voltage (48V to 250V) switch-mode boost supply.
- An NCP1400 based 5V step-up controller. I'm not sure if I'll push this design for kitting.
- The 3.3V version of the popular FT232 USB to TTL converter.
- A constant current controller. When hooked between a load and ground, this allows you to set a particular maximum current level regardless of supply voltage or load variances. This is ideal for loading SMPS, LEDs, Laser diodes, etc.

Arduino and Freescale MPX Pressure sensors (April 29, 2008)
Freescale makes a range of integrated pressure sensors with 0-5V analog outputs, in a vast array of configurations. Today, I've picked the MPXV5010DP, but you should be able to adapt this to a range of sensors.

A High-Volume Atmega Arduino Programmer and Tester (April 1, 2008)
I need to program several dozen Atmega168s and I only own ICSP Atmel programmers; what to do? Bodge one up of course. Best of all, the bodged programmer functions as an Arduino test bed.
