If you’ve ever looked under a car’s dashboard and wondered how all its switches, lights, and gauges work, this little DIY kit I spotted over on AliExpress looks like a fun way to learn about electronics without ripping apart your car’s wiring harness. With a circuit board shaped like a tiny car, the solder-it-yourself kit packs a few of the basic controls you’d expect in a real vehicle. The finished circuit features working headlights, turn signals, hazard lights, a horn, accelerator and brake sliders, a gear selector, and a little LCD panel that displays your simulated speed and distance traveled.
In addition to the circuit board, the kit includes all the resistors, capacitors, diodes, switches, and other electronic components you need. You’ll just need some basic hand tools, a soldering iron, and a pair of 3.7V 18650 rechargeable batteries. Putting something together like this seems like a great hands-on approach to learning instead of just watching a YouTube video or reading a book.
The kit sells for about 20 bucks and looks like a great way to introduce anyone to electronics and to practice their soldering skills. It’s by no means a gamer’s racing rig, but it looks like an entertaining way to learn about circuits and gives you something to show for your effort. That said, it won’t prepare you to work on the insanely complicated wiring harness on a modern vehicle.
