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 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
Bathroom scale v1.2
I’ve been using the XBee-enabled bathroom scale for almost a year now, and it works a treat. Every morning, I hop on, the weight goes to the computer, and the computer dumps the weight reading into a logfile. The server … Continue reading
Sidereal seconds hand
I spent some time thrashing about trying to make sure that the circuit was producing the correct output. I decided to try the Hz counter on my DMM, to see whether it could give me an accurate enough reading. Hooked … Continue reading
Sidereal clock, baby!
…well, I’d need an oscilloscope to confirm, of course. But I converted the Bresenham/Black algorithm to Arduino code, mixed in code from a Timer Interrupts tutorial from the web (I should link to that here), and loaded it up. Worked … Continue reading

Sidereal clock circuit — progress!
I’ve been kicking around the idea of making an accurate sidereal clock circuit for years now. I’ve discussed it all before, but the basic idea is that I want to be able to create a circuit that oscillates at 32857.715Hz … Continue reading

A slice of Pi
I have a Raspberry Pi on the way. Since I’m mostly an Arduino shop, I have to think about how to interface my existing goodies with the new board. This one looks cool:R Pi to Arduino Shields It makes use … Continue reading
Arduino-hating: I don’t get it.
I love me some Arduino. I have several. I build pretty much every project around them. Even when I’m building a circuit that doesn’t use the microcontroller at all, it’s very convenient to have a regulated 5V USB power supply … Continue reading
Arduino power control
The digital scale project has been a measured success, as most maker projects tend to be “in the early revisions”. On the one hand, the circuit works dandy when it’s up; step on scale, weight gets transmitted, computer processes and … Continue reading
