Structural engineering is the art of molding materials we don’t wholly understand, into shapes we can’t fully analyze, so as to withstand forces we can’t really assess, in such a way that the community at large has no reason to suspect the extent of our ignorance.— Dr. A. R. Dykes

I hacked together an Arduino Micro firmware that is a drop-in replacement for a Spiffchorder, long version and code below the fold.
I’m finally not living so dangerously with the data outside my Seafile-synced live set and doing proper backups of all my machines, including laptops. I’m also now storing my various media files on a RAID instead of a single large … Continue reading
A second consecutive CNC post, because I haven’t had time to write up long-form posts for months, and something requiring documentation came up today. While I’m still quite happy with LinuxCNC (especially since I discovered NativeCAM), my adviser bought himself … Continue reading
I’ve been fascinated with machine tools and mechatronics for well over a decade, and have been indulging that fascination with a series of little benchtop CNC machines since about 2008, especially since my collection of related degrees lend legitimacy to … Continue reading
The lab Makergear M2’s heated bed power supply died a few weeks ago, so we decided it was time for a serious upgrade, and set out to equip it with basically the best parts currently on the market, as we’re … Continue reading
I’ve done some invasive repairs on the Macintosh LC from my small fleet of vintage computers. I figure it’s worth writing up because there is a lack of detailed information about this kind of work on the ‘net.
I gave an informal talk for the IEEE student branch about breaking in to your own devices this evening. I did the low-postable-content notes with live examples and links thing, but at least one person wanted to watch the video … Continue reading
I recently picked up a USB RFID reader/writer pod to play with, partly to learn enough to be dangerous about the tech, and partly hoping to tamper with the RFIDs in the current university ID cards. I’m pretty sure I … Continue reading
I’ve been playing with chorded input devices for years, and got the itch again recently.
I gave a quick primer on 3D printing as a Keeping Current (CS departmental) seminar yesterday. It’s not a great standalone deck but posted (in reduced quality, gs -sDEVICE=pdfwrite -dCompatibilityLevel=1.4 -dPDFSETTINGS=/ebook -dNOPAUSE -dQUIET -dBATCH -sOutputFile=/path/to/output.pdf /path/to/input.pdf is good magic). It … Continue reading
