In this Instructable I will walk through how I build my new and improved Macropad. I made one a while back and it has always had some things I would like to improve on it. The main one being the location of the state LEDs. When redesigning the case I figured why not take a […]
This project will show you how you can create your own programmable thermostat with temperature probe, an LED readout and ability to remote control outlets. The core of this project is actually a driver for a 4 digit seven segment display. There are lots uses for such a device. You can purchase something called a PID

Signal and power from the same voltage source Most hobby electronics store carry cheap and ready to use digital voltmeter modules (DVM) the problem with those is that they do usually require an independent power source to power the DVM-module. Many circuits are made such that you have one power supply and you would like

illustrates a digitally programmable precision resistance that can serve as a microprocessor-driven power-supply load in custom-designed ATE (automatic-test equipment). An 8-bit current-output DAC, IC1, a DAC08, drives current-to-voltage converter IC2A, which in turn drives the gate of power MOSFET Q1. The device under test connects to J1 and J2. In operation, current from the device
