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
Breadboard works
With my initial hubris about circuit construction dulled by a couple of nasty bugs and failures, I decided to construct my next circuit the old fashioned way — I bread boarded it first. I wanted to do an I2C version … 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 – Getting the hang of it
With my first PCB under my belt, I was ready to etch a board for something I really need. I took the lessons learned last week, and was able to produce a really nice result this time. This is a … 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
