Port-Powered Temperature Meter This is a four-channel temperature measurmet adapter that works without external power supply. It will suitable for measureing temperature and logging its data with a PC. The circuit diagram is very simple and no adjustment is required, everybody will able to build it with ease 🙂   Specs. Micro-controller ATtiny15L (Atmel) Number […]

With all the details on a circuit different from that to which the shared a marquee computer control program atmel at90s2313 source software image format you have the source schema and pcb, orcad drawings. Marquee on a circuit different from that to which Marquee in 350 LEDs used micro-controller atmel at90s2313 led 7 74hc595 are apparently taking the pc […]

Universal Counter The frequency counter is the most popular instrument in the home maid instruments. I think that the reason why it is built widely is: it can be built easily because it is digital circuit, it is generic measurement and many construction kits are available. Many electronics hobbyists will experienced to build any frequency […]

Description This is the fully featured, jammed packed temperature readout unit. I can measure temperature from up at 8 DS1820 digital temperature sensors all on the same 1-wire bus. That’s right only 3 wires are needed to go to all the temperature sensors, GND, VCC and 1-wire data. All sensors will connect to the same […]

Here is some experimental hardware and software to transmit and receive AX.25 packets. It is essentially a PIC-E clone designed around a Atmel AT90S2313 with a few extra bells and whistles. I had picked up a couple of MXCOM MX-614s at the TAPR display (I also joined TAPR) at the Dayton Hamvention, and I needed […]

Introduction: This is the hardware and source code for an Atmel ATmega48 based four digit Nixie Tube Clock. Description: This was my second Nixie clock project. I wanted something a little smaller / cheaper / simpler then my rather large B-7971 clock. I will post the design for that one of these days. Trying to […]

Atmel On the PC keyboard PS 2 AT89C2051 keylogers circuit connection cable connects to the circuit between what is written in the wake of the program running on the pc upon AT24C512 writes eeprom eeprom reading with KeeLog has decided to release an early version of it’s hardware keylogger family to the public domain. Including full […]

description (hardware) Above and below you can see the terminal. The LCD display is represented by the connector X1. It has a HD44780 compatible LCD controller and I’m using the 4-bit interface to send data to the LCD controller. The LED’s are multiplexed. I’ve seen the circuit somewhere in the web. It is possible to […]
