20220710 The Upper Panel PCB
THE FINAL REVISION After taking a closer look at the 3D printed TR-595E’s body, I believe I can mount this PCB flat-faced. In other words, only the LEDs are on the upper side of the PCB and they can fit into the already pre-made windows. All I have to do is to just relocate the […]
20220710 The Height of the Relay
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, […]
