Illuminato board project – it’s an Arduino / Freeduino board that has 42 digital IO’s and 64k code space. All of the schematics and files are over here.

XBee modems are one of the easiest ways to create a wireless point-to-point or mesh network. They have error correction, are configured with AT commands, come in multiple flavors and can create a wireless serial link out of the box! I wanted to make a wireless Arduino project but all the adapter boards on the market made me unhappy. So I designed what I think is an excellent low-cost adapter board.

Made this in order to test the samples I (again) got from microchip… (coolest guys in the world.. If I ever make something sellable in huge numbers with a microcontroller, it will surely be a PIC :).

This is a USB (universal serial bus) interface board which can be used to connect 8 (parallel) data lines to the USB. The interface comes with a small internal FIFO (384 byte Tx, 128 bytes Rx) and 4 handshake lines which make it suitable for interfacing microcontroller designs to the USB.

It can, also be used as simple 8bit IO when the so-called “bitbang mode” is enabled. Note. however, that in this mode, the bits will not come out in a constant bitrate but in chunks of 64 bytes with specified baud rate followed by a delay.

This looks like a nice developmental board for programming an ATmega8. The website has some sample programs and the Eagle files so you can make your own. [via]

I made the board using my photo etching technique, and as you can see the results are great. The dev board has 17 I/O lines that are connected to a 17 pin header. On the board there is a 2 color LED tied to PortC pin 1 and 2. On PortC pin 0 there is a PNP transistor that controls the output for a buzzer.

David Fowler at uCHobby has introduced his new-and-improved breadboard power supply, which is both an excellent introduction to soldering technique *and* a useful tool for further electronics work.

Indeed it is a nice little board – with additional header pins to bring power out to both sides of the board and add some extra stability. Jumper selectable 3.3/5V operation, plus one feature I don’t see often enough on supplies like this – a power switch. It seems one should consider adding a heatsink to that voltage regulator if you plan on using an input source higher than 25V. [via]
