20240714 New Test Programming Clips
In the beginning, during the prototyping stages, I tend to rely on the prototyping breadboards a lot. These breadboards are essential because they would be the basis on how the actual PCB would be designed from. 1. Translating the circuit onto the breadboard. When I draw up a circuit on paper, it was fun. To […]

A few years ago, I discovered the existence of resin flux and liquid solder. They come in the form of syringe-like containers. You can dispense them using the plunger as if it was a syringe. If the plastic was too weak or too tall, you then have the choice of using those aluminum ones. I […]
