Seasoning a humidor means getting it ready for cigars by saturating the wood with moisture, so that it no longer is hygroscopic.
Temperature and auxiliary sensor (RS-485), AVR
Temperature sensor with serial RS-485 interface. Two additional sensors can be connected using 3-pin headers on the circuit board. Uses an AVR ATmega8 microcontroller.
Temperature and humidity sensor (RS-232), AVR
I rebuilt an existing interface module — to be a stand-alone temperature and humidity sensor, with serial RS-232 interface. Uses an AVR ATmega8 microcontroller.
Temperature and light sensor with signalling LEDs (RS-232), AVR
I rebuilt an existing interface module — to be a stand-alone temperature and light sensor, with serial RS-232 interface and some signal LEDs. Uses an AVR ATmega8 microcontroller.
Portable alarm system (school project, electronics)
Portal alarm box unit, my main project on technical college.
Car warning lights, with AVR controller
Strobe light controller, using the AVR ATtiny2313 microcontroller. Meant for cars; with front, side and rear warning lights.
The rack box project — an overview
A 19" rack cabinet filled with electronics and AVR microcontroller modules — I called it: The rack box project!
Serial interface module, with analog and digital I/O — AVR
Serial (RS-232) interface module; providing 6 analog and 2 digital inputs, and 9 digital outputs. Uses an AVR ATmega8 microcontroller.
Serial port I/O module with 15 inputs — AVR
Serial (RS-232) interface module; providing 15 digital inputs. Uses an AVR ATmega8 microcontroller.
AVR car front lights controller
Lights controller for high beams and fog lights on my Subaru. Uses an AVR ATtiny2313 microcontroller.
