usbasp_one_sided_design.zip by ermanojghimire

USBasp is a USB in-circuit programmer for Atmel AVR controllers. It simply consists of an ATMega88 or an ATMega8 and a couple of passive components. The programmer uses a firmware-only USB driver, no special USB controller is needed. Its the onesided design, I tested this design in real hardware and working perfect. Enjoy.

arduino_shield_gsm-quectel_updatetid_2_v1.3.zip by drak

The Arduino GSM Shield connects your Arduino to the internet using the GPRS wireless network. Just plug this module onto your Arduino board, plug in a SIM card from an operator offering GPRS coverage and follow a few simple instructions to start controlling your world through the internet. You can also make/receive voice calls (you will need an external speaker and microphone circuit) and send/receive SMS messages. As always with Arduino, every element of the platform – hardware, software and documentation – is freely available and open-source. This means you can learn exactly how it\'s made and use its design as the starting point for your own circuits. Hundreds of thousands of Arduino boards are already fueling people’s creativity all over the world, everyday. Join us now, Arduino is you!

amp-tda2005-bridged.zip by admin

A small 20W Bridged Channel audio amplifier using TDA2005 IC. Including volume control. 12V PSU is Ideal. Heatsink required for IC. By defualt, the design only displays the bare circuit in \"board view\", so just enable the necessary layers for component values and pinouts.\r\nUploaded by Bradlin Basson from South Africa

ft232_modul.zip by admin

USBSeriell(TTL) converter modul based on FT232BM from FTDI (www.ftdichip.com). Designed for easy self-etching this project only need a single layer board. Boardfile, schematic, partlist and short description is included in zip-file. Very usefull to easily hook up small microcontrollers with UARTs to usb. No need for driver programming when using virtual-COM-port drivers freely available from FTDI.\r\nUploaded by Lutz Lisseck from student

lm304-led-treiber.zip by Guenter

LED-Treiber für Spannungen von 6VDC bis 48VDC (75). Dimmbar mittels Potentiometer über PWM zwischen ca. 5% und 98% des maximalen Ausgangsstromes, welcher über den Sense Widerstand von 100mA bis 500mA eingestellt wird. Der PWM Generator wird vom LM3402 versorgt, weshalb hier nur CMOS Typen eingesetzt werden können. Die Versorgungsspannung, verpolgeschützt über eine Diode, kann über einen Kleinspannungsstecker max. 3A oder eine 2-polige Klemme zugeführt werden. Eine Weiterleitung der Versorgungsspannung zu weiteren Einheiten kann über die Klemmen erfolgen, so dass bei einer RGB Anlage nur ein Zuleitungsstecker benötigt wird. Die LED werden über eine 2-polige Klemme angeschlossen. Somit können an einem Ausgang bis zu 14 LED in Reihe versorgt werden, dies jedoch nur bei 48VDC Versorgung. Bei Spannugen über 36VDC muß die Schaltung jedoch direkt mit dem Netzteil verbunden werden, da mögliche Induktionspanngen beim Anschluss eines hochgefahrenen Netzteiles das Regel IC zerstören könnten.
