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 […]
DIY or BUY a SMD reflow Hot Plate?
SMD VS THROUGH-HOLE The advantages of using SMD components (surface mount) as opposed to the conventional though-hole versions is that SMDs are smaller. Because of that SMDs does not consume too much power. The disadvantage of using SMD components (that exists in millimeters)is that soldering them is really a b*tch. My original decades old circuits […]
A Relay Delay
Well, I have a problem now. After going through the Datasheet again, I need to either give it the correct voltage or at least close to 80%. In other words, these 5 volt relays require a minimum of 4volts before it can do anything. It was so sad last night when I rushed back home […]
