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
CNC – Super-PID
I got some time in the shop today and decided to test out the axis accuracy of the new CNC. I still have tuning to do; you definitely can’t run the router through wood at the same speed as you … 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 – more small tweaks
I had just a short session working on the CNC today. I moved the router downwards in the mount so that I could reach the collet nut. This makes getting at the button more difficult, but nothing a flat screwdriver … 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

CNC Build, Day 40 – ready to cut
All that was left to do before I can start cutting is mounting the router and cleaning off the table. I put the router in place, which went very smoothly. Then I got the clamp bolts drilled and installed. Easy … 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
