So in my recreational time, I would buy DIY soldering kits from China. Initially it was for soldering experience but then I got addicted to buying them. That’s what I call a healthy addiction!
Along the way, I learnt how to solder, understand the mechanical construction of a circuit using screws and standoffs and learnt how various circuits work from power supplies to LED matrices.
LED Heart Kit
The schematic and BOM for this circuit is so simple x1 STC15W408AS LEDs AA battery holder No current-limiting resistors are required! Also, somewhat peculiar is…
LM317 Adjustable DC Regulated PSU
Introduction Now we’re getting into the dangerous exciting stuff. I recall this kit being fairly straightforward to assemble. No SMD components or fine-pitch THD component….
Bluetooth Speaker
Arguably not as exciting as the FM radio but still cool. As you can see, I didn’t realize how the acrylic pieces mated together so…
FM Radio
Specs STC15W408AS MCU 4 buttons for volume and frequency control Current channel display via 4-digit 7-segment display Power via x2 AA batteries or micro-USB UART…
Portable Light Source
This was my FIRST EVER Project. It’s not much but you have to start somewhere. Schematic and a photo of the circuit constructed in-real-life is…
