Business card AVR breakout boards: Version 1.1

By on

Card version 1.1

We’ve just released a new version of our super-handy business card sized target board for programming 28-pin AVR microcontrollers like the ATmega168 and ATmega328. These are just the thing for programming these chips through an ISP programmer like the USBtinyISP.

We use these for a lot of our simple microcontroller projects; Tennis For Two and the Lissajous POV come to mind. The new version has basically the same design but adds some extra prototyping area and makes the holes big enough to accept a ZIF socket:

Like the original version of this target board, this circuit board is a fully open source hardware design. For much more information– including the detailed design files– please see the update that we’ve added to the end of our original article about this project.

The Sashimi Tabernacle Choir

The Smithsonian Channel’s series America Wild & Wacky is featuring ArtCar Fest. In a blog post about the episode, they linked to my flickr video from Maker Faire of the Sashimi Tabernacle Choir. Here for your entertainment is my clip of hundreds of computer controlled singing sea creatures performing Bohemian Rhapsody.

No Refills?

Maker Faire Austin

On our way to Maker Faire Austin, we grabbed a bite to eat at the San Jose airport, where we saw this rather confusing sign on a soda machine:
“NO REFILLS–Refills Available For .59¢”
So which is it, refills or no refills? And do they really make change for a penny?

lovely sign for the show barn

We had a wonderful time at Maker Faire Austin. I’ve put some pictures and videos up in this flickr set for your enjoyment.

Electrified Monopoly   Maker Faire Austin

Our neighbors at Maker Faire were Kris and Carly who were doing very fun things with LEDs, like making Monopoly more fun by lighting up when you land on certain squares. The no-solder wiring system was very clever, and the flashing blue and red lights in jail were perfect.

Maker Faire Austin   It's the gnomes that make it perfect

This cute little robotics platform stopped by for a visit, but in order to see most of the rest of the faire we had to pry ourselves away from our table, which was tough. There was a nice collection of art cars, including this Chia Car. Maker Faire is wonderfully overwhelming, and we didn’t take very many pictures. Luckily, many other people took pictures too, and you can check lots of them out on flickr.

LED Ghosties for Halloween

LED Ghostie

You can make these simple LED ghosties (based on LED throwies) from a soda bottle, a couple of LEDs and batteries, string, and a scrap of fabric. Hang them in your trees, your haunted house, or in your porch for Halloween. They look especially excellent because the eyes seem to float in mid-air behind the fabric.
