I’m building a ipod wall charger from scratch and the burning question was how much current does an ipod nano consume when charging? Well today with a quick test setup I found it to be 100mA. This is great news, the USB specification allows for 500mA on a port but the Ipod uses only a small part of it. Expect a circuit and/or tutorial of the charger sometime in the future.

Today I added a small page for the USART communication test program I use. Its a very simple implementation of the hardware USART capabilities of the Microchip PIC18F1220 micro controller. You can find the page here: USART communication (hardware).

And I have a long overdue site update to prove it! Im working on a Terrarium Project and one of my tasks is SPI communication. I wrote a quick page for it, you can find it here. As always comments are welcome.
