This project for testing CCPM servo setup. This device allows you to connect 1-3 servos simultaneously. It can be used as a servo signal generator for testing electronic speed controller (ESC) without using a transmitter and receiver. Also, this device can be used to check other RC devices.[more]
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. The low frequency end is limited by the AC coupling of the line-in signal. Be aware, that most microphone inputs are only mono. Donwload from link below.[more]
An oscilloscope is probably the most important instrument for observing and measuring electronic circuits. It allows you to observe timing, voltages, slopes, curves, and spikes of an electronic signal. A good digital oscilloscope can easily run you over $1000, but this scope will cost you a grand total of $40 for the kit, perhaps the cheapest scope you will ever buy. [more]
Talking Voltmeter takes a voltage measurement in the range 0-5 Volts and then reads it out to you to two decimal places (i.e. to 10mV resolution). The design illustrates the use of the 10 bit ADC in the PIC, as well as pulse width modulation (PWM) for analogue output. This project also illustrates how to squeeze every last word of program memory out of a PIC Sound samples consume almost all of the on-chip flash memory, and even that was after some pretty brutal trimming of the samples and a drop in resolution to seven bits.

This submini USB scope is based on a Atmel Tiny45. It has 2 analog inputs and can supply 5V ont 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]
