Overview
CircuitPet is a DIY virtual pet similar to Tamagotchi. This gadget teaches about RTC (real-time clocks), microcomputers and other electronic components, TFT LCD displays, embedded programming, video game mechanics, coding in C++.
Like any other pet, you can play with it, take care of it, love it and help it grow!
Unlike other pets, you can take a break from CircuitPet. But even a digital pet can break down if you leave it without love for too long. Don't let your duckie rust!
Check-in every once in a while to make sure it has everything it needs to be happy.
No prior knowledge needed.

Another Slot Car Lap Counter, but if I did it anyone can do!

If you need a device which draws a certain amount of current and power for testing, then GreatScott! has just the solution. His project uses an Arduino Nano, along with a separate IC and a voltage divider, to measure both current and voltage input from the power source. It then employs this data to properly adjust a MOSFET, dissipating the correct amount of voltage and power as required. Interface is handled via a rotary encoder and a 16x2 I2C LCD display, and the electronics are housed in a solid-looking enclosure. As seen in the video below, the adjustable constant load features an impressively large heat sink, needed to take care of the 30V and 20A that the setup is capable of drawing.
