The circuit boards from dirty pcbs for SMD May are here just in time. The Logic Pirate is a nice cheap compact logic analyser design by Markus Gritsch. More at Dirty PCBs and Dangerous Prototypes.

You can see from looking at the block diagram above that the isolation is transformer based, it’s quite remarkable that they can fit 5 transformers in such a small package. If you can’t attend the workshop the pcb files can be found on github and all the parts at Newark/Element14. Newark/Element14 have an excellent video […]
In one of the earlier SMD workshops I managed to temporarily kill my new macbook pro when I plugged in a prototype. I revived it by removing the battery all the time chanting to myself, must get a usb isolator, must get a usb isolator, must get a usb isolator….. This is a nice simple […]
For SMD March we’ll be building an Internet of things board. This is the heart of an arduino uno coupled with an ethernet interface to let you control leds, relays etc, plus read switch positions, temperature etc. all over Ethernet. Like a uno, it has a usb interface for programming with the Arduino GUI and […]
Although, I guess “fun” is always implied when lasers are involved. I shouldn’t have even bothered. Here are some things lasers are good for: 1) Organizing your kitchen. 2.) Clamping stuff 3) Holding worm gears 4) Showing up 16th century engravers Anyway. I hope you’ve found this post informative, […]
Here is a demo video of the awesome vhs led badge designed by Richard Sim. These are mostly assembled, we’re holding workshops in January to finish the build and learn about how they work. This board has a Atmega 168/328 CPU connected to a 8×16 LED Matrix with both red and green leds via a […]
The VHS 5th Anniversary LED badge is a Atmel 168 based board with an Altera CPLD driving a two colour 8×16 LED matrix. Other features include a 5 way joystick, separate button, expansion header for i2c peripherals and a microphone. The board was designed by Richard Sim and will be partly assembled by you! We […]
