Daniel build this clock after having to chose from a watching a movie or working on a project. Obviously he and hi’s friend chose to make the clock so it wassn’t long until the LED’s started to light up. The clock code is based on the open-source-arduino-clock by Rob Faludi. Daniel made many changes, but the time counting the basically the same. So if you want to make another kind of clock, I suggest you to take a look on that code.

This project is based on the previous one posted and here the DCF77 runs the clock from the thermostat always on the right time synchronizing not beeing necessary anymore. The temperaturesensor is a DS1820 or DS18B20 and on a HD44780 (or compatible) 2×16 LC-Display becomes day, date, time, temperature (with 0.1°C precision) and an indication which temperature adjustment (economy- or comfort temperature) is active.
For each day there are 4 ON/OFF times to program, ON means here switch to the comfort temperature and OFF to the economy temperature.
A handy option is for people who work at different times (shift work) because it is possible to program the clock with a 2-weeks scheme.
As you can see a really complex program has been created for this project which makes it really handy for those who need it.

This project make use of a PIC16F628(A) and a DCF77 receiver from Conrad. Optional there is a possibility to connect an electronic gong on it. Every second is on PORTA.1 (pin 18) a pulse from 0.5 second. This signal isn’t necessary for anything, but maybe you want to connect a LED on it, so that these wil blink every second, or a piezo buzzer, so that the clock ticks as an analog clock.
Overall the project is great and someone put allot of work into designing it.

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.
