I had neither Arduino nor batteries. So I made do with an atmega168 with an Arduino bootloader burned and connecting to a power supply with the servos running off the 5V regulator, which got very hot.

Homemade Arduino

Homemade Arduino
This is a fully Arduino-compatible setup based on the Arduino breadboard except with a USB to serial converter and an RS232 level shifter instead of the FTDI chip. I used the parallel cable I’d made previously to burn the bootloader, then I was able to program it and to communicate with it via USB. This was all done using the normal Arduino software on Linux.

My First Microcontroller

My First Microcontroller
I finally got round to trying my hand at microcontroller programming. Following this instructable it was dead easy. The main problem I ran up against was in the software. On Linux you need the ppdev module in order to have access to /dev/parports. In menuconfig it’s Device drivers -> Character devices -> Support for user-space parallel port device drivers. On Debian you need the following packages: avr-libc binutils-avr gcc-avr avrdude Your user also needs to be in the lp group for access to the parallel port.

Komodo 3 - inverter circuit

Komodo 3 - inverter circuit
The led on the motherboard’s built-in network interface is normally on and blinks off on activity, I want it the other way round. This is a simple transistor inverter circuit which controls the front mounted LED. Unfortunately the LED resistor is too small and so the LED is much too bright.
