smoker-pid-control
Arduino based PID and Fuzzy Controller with PT1000 temperature element and Adafruit MAX31865 RTD Sensor Breakout module to control heat in BBQ grill using a blower fan.
NiMHTurboCharger
Some PCB Layouts for small high power charge circuits 2A to load a series of 2 or 3 NiMH akkumulators. It uses the Linear LTC4060 which is a very small device and needs only a low number of external parts.
UV-LED-PCB-Exposure-Unit
Renesas R8C MCU UV-LED Exposure Unit for foto sensitive PCB work using Rotary Encoder and properitary 2 wire protocoll for HD44780 LCD Display based on an AVR example from Austrian CC2 Computer Club http://www.cczwei.de/atm18_downloads/ATM18_LCD.zip http://www.cczwei.de/index.php?id=atm18_download.
Aircondition
A Project using TX21IT+ wireless 866Mhz sensors with RFM12 and PIC24F to control air ventilators based on absolute humidity.
ATtinyFanControl
Drive an 4 pin PWM Fan using an ATtiny45 or ATTiny85 which was harder than I thought
frigate2pushover
golang based Docker container to sent Frigate NVR Messages/Snapshots as Pushover Notifications
Geiger-Counter
Geiger-Counter to measure alpha, beta and gamma radiation Portablecounter with long lasting battery supply using minitubes. Planned Features also include USB and micro-SD Card reader to support evaluation of long term measurements. Utilized Software: Eagle PCB Layout, LTC Spice for simulations. Only HV part is finished.
Homeautomation
Moteino and Node.red based Home Automation and Security System
motiondetector
Combined Motion Detector using Radar and PIR Sensor
