This project has two main functions on the one side you can read the RC5, RC5X and RC6 codes from remote controls on a LCD and on the other hand you can send all thinkable RC5, RC5X and RC6 codes to a device.
When the TSOP1736 (IR receiver) receives an infrared (IR) signal from a RC5 or RC6 remote control (like Philips) burns LED1 (green). The LCD shows when it receives a new type of code for one second which protocol is received (RC5, RC5X or RC6). After then the LCD shows the RC5 or RC6 system- and command code in decimal as wel in binair. The toggle-value is shown by LED3 (yellow). LED2 (red) burns if the received signal is poor or if it’s not a RC5, RC5X or RC6 signal.
With the IR-transmitter it is possible to send every possible code from the RC5, RC5X and RC6 protocol, like a remote control does.

This is actually version 2 of the syringe logic probe, so it has some improvements over the first one. The advantages of using a syringe as a logic probe are obvious, you can reach small pins or solder points. The probe wassn’t yet tested at high frequencies, but it works well enough for sniffing AES keys from an SPI bus.

This 3-digit digital thermometer is easy to build for beginners or hobbyits. PIC16F628 is used to read digital values of temperature from a DS1820 sensor. All 7-segments are driven by a power logic 8-bit shift register TPIC6B595 with open collector output. For the 7-segment we need 12V volt to drive it because it has 3 LED per one segment. Source code in C Compiler is available.

This clock counts seconds, minutes, hours and day of the week. Time is displayed on 4 seven segment LED displays, and is adjustable with three buttons at start time (up, down, enter). You can program the day of the week, hour, minute and duration of the alarms.
The number of alarms are limited by ROM space only. The alarm is on the RA4 open collector output of the PIC, and is repeated on a decimal point of the display. For once, the program is in BASIC (mikroBasic) and this should make a good start for beginners.

Some would say that an electronic dice would take the fun away from the game, but I’m not sure that’s always true. Anyway as the friends from PyroElectro say “we’ll make it anyway”. It’s based on the ATmega8 which controlls 7 LE’s that show you the number. All the schematics and source code is available for download.
