# ArduinoThermostat Arduino thermostat to control a beer fridge to use it as an environmental chamber. ![](ArduinoThermostat.png) --- # HydraBot Current state of HydraRaptor after being modified for laser engarving. ![](HydraBot.png) --- # IOT 50V PSU WiFi controllable PSU ![](IOT_50V_PSU.png) --- # Lab ATX PSU Bench power supply built around an ATX PSU. * Cheap LED voltmeters show the voltage on the four main outputs. * The 5V standby output is available from a USB socket. The main PSU can be switched on with a switch or by pulling the green socket next to it low. * The green LED shows the power good signal. * Dummy loads keep the outputs in range. ![](Lab_ATX_PSU.png) --- # Laser Load 15kV dummy load for testing CO2 laser PSUs ![](Laser_load.png) --- # MainsBreakOutBox 13A socket break out box with 4mm jacks to measure voltage and / or load current and earth leakage current. ![](MainsBreakOutBox.png) --- # Mains Box Mains isolated and variable supply with metering. ![](Mains_Box.png) --- # Turntable WiFi enabled remote control turntable for photography ![](Turntable.png) --- # Variac Motorised variac with WiFi control, see [hydraraptor.blogspot.com/2018/04/esp8266-spi-spy](https://hydraraptor.blogspot.com/2018/04/esp8266-spi-spy.html) ![](Variac.png) ---
