I have completed a XR2206 function generator kit build.
I have completed my build of Jay_Diddy_B’s 5 Transistor ESR Meter.
Transferring the digital clock circuit to a perfboard and putting it into an enclosure.
Sleep mode and Schmitt trigger on multiplexed analog buttons. Also, now the clock is powered by 18650 Li-ion cell.
Replacing Arduino Nano with regulatorless Arduino Pro Mini.
Adding buttons, alarm buzzer, temperature and humidity sensor, brightness potentiometer, and menu system.
Transferring the circuit to a bigger breadboard.
Adding the LCD display for the Arduino-based digital clock.
I want to make a digital clock. Not from the scratch, I’ll use whatever modules I already have.
A tool to test devices for short circuit or big inrush current.
