With the 3D part in my hand, one of my questions has been answered. The height of the relay is just a smidgen shorter than the uppermost ledge which is about roughly 5mm. These ledges are responsible for the Lower Interface panel not dropping into the whole cavity. The 5mm height limit is quite a […]

20220708 The ULN2803AFWG
Remember in my last few post, I asked, ‘What can go wrong?‘ and then I approved the design with JLCPCB? Yeah, I found a much better circuit solution. I AM SO SMART, DUH I always use the ULN2003 Chips or its variaton to drive the LEDs. It is basically a driver for higher current components, […]
20220707 A great catch from eBay
In Malaysia, it is very hard to get the Star Trek stuff then I like despite seeing some bits here. To be honest, they are not as ‘popular’ as Star Wars and thus, most vendors would not bring them in because: 1. They do not sell, or2. Not many people would buy them, or3. The […]
20220707 Auto Routing
THE FUN OF AUTO-ROUTING I am starting to appreciate the auto-routing features in the EaglePCB. It gets the job done and looking at the image below, saved me hundreds of hours. I am very thankful of that fact. Auto-routing is so simple. I just prepare the PCB design, make sure my schematics are correct, and […]
