I think this is Cool idea related to Microcontroller project created by J. Lepot. This USB scope is based on a Atmel Tiny45 cpu and cost less than 5€ with a homemade pcb. It has 2 analog inputs and can supply 5V on the 4 pins header on the right. One of the inputs can be scaled down with the trim pot.

The firmware in the Tiny45 is written in C and compiled with Winavr and usb source code from obdev. (more…)

It is a universal lithium ion battery with a battery charger intelligent interface based on a microcontroller Atmel ATmega8 using GCC worm. 3.2. The rate settings are established using one of three methods: a Smart car if the battery is detected, the battery settings are used. If the "Custom" is selected then the settings are using on-board DIP and variable resistance. If not, pre-sets of parameters are selected on the basis of other positions DIP

This is a frequency generator project based on IC 555CN. Nice electronic project for new electronic beginner.

How to make a Frequency Generator:
On cloud busters Fredbuster created a wonder tutorial for getting started and building your own Zapper. Fredbusters Tutorial in PDF-Based off his design here is how I made my frequency generator.
