AVR In Circuit Emulator with USB-A Interface

AVR-USB-JTAG has all the power of the original AVR-JTAG plus the flexibility of a USB interface. This is a low-priced equivalent of the much more expensive JTAGICE, with a handy and safe optically isolated USB interface. Use it to debug and emulate many of the Atmel processors!

Ni-cd, Ni-MH charger

Ni-cd, Ni-MH charger board

This Ni-cd, Ni-MH charger features charging at constant current and automatic charge stop when the cumulated voltage for all cell’s reaches the desired value. The project is designed to charge 4 Ni-Cd/Ni-MH cells. This kind of chargers are not expensive to buy, so you could chose a commercial version, but if you’re into electronics you’d probably want to build one yourself.

Li-Polymer charger

 Li-Po charger

Li-Polymer batteries are more advanced than the old NiCd/ NiMH batteries, thus giving more juice and longer life period. If you are already using a Li-Po battery on your RC model or robot, you notice that the chargers for this type of batteries are quite expensive, so why not build one yourself, you will save some money and have a lot of fun.

ATMEL ISP Module

 ATMEL ISP Module

ATMEL Microcontrollers can be programmed with ISP(In-System Programming) which helps to develop your applications because you don’t need to insert/remove the microcontroller. This is an ISP module for ATMEL Microcontroller that supports ISP such AT89SXXXX, AVR families etc. It Requires no power supply because it uses power supply from target board. This circuit needs only 10 resistors, 1 IC, 1 Capacitor,1 R-Pack.PCB size 1.6 X 4.1 cm. and Plated-Through-Hole type.
