PCB – The sun is the thing

I finally got back on the PCB fabrication horse. I printed out v1.1 of the 74HC595 LCD backpack, and v1.0 of the MCP23008 version. I chopped up the transparencies and mounted them up on Saturday, then worked on getting the … Continue reading

PCB Fab – Breadboard first!

After failing to get the 74LS174 board working, I decided to go with the flow and build a 74HC595-based LCD driver board instead. There are plenty of examples online, from Adafruit to Steve Hobley to Rowan Simms — this will … Continue reading

PCB Fabrication – OK, I over-reached

I decided to tackle my first circuit that includes an IC. I picked an old standby, the Myke Predko 2-wire LCD backpack, where he uses a Hex Buffer (74LS174), wires it as a shift register, and then uses a diode/resistor … Continue reading

PCB Fabrication – been there, done that.

Well, I did it. I decided to tackle something simple for my first attempt at etching a circuit board. I wanted something with a low parts count, and that was easy to test. I decided on a voltage level shifter … Continue reading

Thinking about PCB creation

So far, I’ve been able to successfully avoid making my own printed circuit boards (PCBs) for all the electronics projects I’ve done. Between Protoboards (letting someone else do the etching), perfboard (which I hate, but end up using), and “deadbug” … Continue reading
