And it’s away to JLCPCB. All these revisions are costing me quite a bit in terms of cash and more importantly, time. Every time a design is sent out to them, I would only get it in about an average of 2 weeks. So, I have to check the design very carefully and be certain. […]

20240726 LIR2032 vs CR2032
The normal PKD2019 For the Project of lighting up the Blade Runner blaster, I was counting on using the CR2032 coin cell battery to light up the red LEDs. The reasoning was due to the red and green LEDs whose forward voltages were 1.8volts and 2.2volts respectively. But after some time, when the voltage nears […]
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 […]
LED Resistor Values for Current Limiting Resistor by Cody Wabiszewski
This is a very good primer for those interested in LED lighting. The Author explains the reasoning why a current limiting resistor is a must and also why we do not exceed that 20mA limit.
