The circuit is able to burn a firmware into the microcontroller and uses only a 74HC00 (or 74HC132) and a couple of transistors to operate; it connects to the PC via RS232 native port or USB to RS232 interface. The control program, written in VB6, is fully available, in executable or source code form (easy to modify for implementing other micros). The circuit printed board layout in PDF 1:1 format and the electric schematic are also downloadable from the site below:

This charger is an automatic one that will prevent battery from overcharging. The circuit consists of two main parts a voltage and current regulator and a voltage monitoring circuit with a cutoff relay. When the battery voltage is below 12.6V the it’s charging and when voltage goes to 13.8 then charging process is stopped. [via]

The Soundcard Oscilloscope receives its data from the Soundcard with 44.1kHz and 16 Bit resolution. The data source can be selected in the Windows mixer (Microphone, Line-In or Wave). The frequency range depends on the sound card, but 20-20000Hz should be possible with all modern cards.
