Networked Arduino
I picked up two separate Ethernet solutions for Arduino while I was at Maker Faire; an Arduino Ethernet Shield, and a Nanode 5. Once I got them home (and got the Nanode soldered together), it turns out that they use … Continue reading

Spring projects
Maker Faire comes at the perfect time each year. I’ve worked my way through all of the winter projects, and starting to think up new ideas. The projects that are on my mind at the moment: – home automation (start … Continue reading
CNC – cable runs
I spent some time in the shop today, getting the cables run on the CNC machine. It’s been another one of those long hiatuses, and I needed to get out there and make the thing cut. I needed to crimp … Continue reading
CNC – thinking about wires
I spent Saturday running the soldering iron. Among other things, I was able to construct a trio of Hall Effect switches that I’m going to install on the CNC machine as home switches. I breadboarded, then soldered the circuits together … Continue reading
Wireless Arduino programming
That was really cool. There are times when you end up doing something hardcore and not realizing it until it happens. There are other times when you set out to do something hardcore, and you are just amazed when it … Continue reading
More bathroom scale madness
I got the bathroom scale circuit logging data to an SD card tonight. The Adafruit logging shield came in handy again. I had to work through a number of issues; in particular, the sd card in the shield was dead, … Continue reading
Hacking a bathroom scale
I decided to keep closer track of my weight. As a geek, that means some kind of spreadsheet or database, and as a programmer, the thought of having to enter day manually seems wrong somehow. So the obvious next step … Continue reading
CNC – gross calibration
I needed to figure out the problem with racking in X (you can see it if you look closely at the video). Turns out that my initial suspicion was correct; the sprockets had been twisted relative to each other while … Continue reading

Eye-Fi — easy Arduino internet access?
The Arduino has multiple ways to get online, from ethernet shields to ones with built-in RJ45 jacks. Then there’s all the Xbee / Bluetooth type stuff or even the USB-to-serial bridge, if you are OK involving a PC. But “easy” … Continue reading

RFID and other proximity sensing
So, I finally got the RFID kit (originally purchased at Maker Faire 2010) working. The original kit came with an RFID tag incompatible with the reader. This is why I hate buying things from MakerShed. I am interested in experimenting … Continue reading
