  • PLC and Hardware Control

    Take a survey related to the following Aha! Thank you, Dad for my new Arduino hardware controller (and the partially-outfitted Craftsman toolbox to make my life simpler when building stuff)! Easy easy to program, and easier to wire up! There was a time a few years ago that we were playing with a Seimen’s PLC at my old job,…

  • Privacy Policy

    Who are you? I’m some white cis male nerd from the United States. What personal data do you collect it and why? Comments I log your IP. Not for anything malicious. Just to reverse-DNS you if I think you’re interesting, or to drop you on iptables if I think you’re being an asshole. Also I…

  • DMX for actual Electrical Engineers

    So it’s been coming up recently that our church media department has been buying “OpenDMX USB Dongles” for upwards of $80. I was mortified, especially after seeing this USB device, opening up the sheet metal project box and finding it to be a simple 2-stage USB to RS-485 protocol bridge with no programmable intelligence whatsoever.

  • A Fun Adventure in PGP

    So I got curious about PGP keys and signing and encrypting using them. I managed to figure out how to use the semi-popular gpg4win (the standard windows port of GnuPG) with its built in Kleopatra GUI, Outlook add-ins and all the other fun stuff.

  • Embarcadero TThread Works Just Fine

    I’ve been annoyed for a large amount of time (years in fact) over some of our software we use and sell. In essence, what we have is a TCP GUI that communicates on a 250ms timer with a microcontroller that’s serving up a two-way communications protocol over ModBus FC23 – we send commands either to…

  • Linux – Find what is Preventing You from Unmounting a Drive

    Disclaimer: I’ve had this problem for probably four months, ever since I started running Plex Media Server on my headless linux machine at home, whilst storing all my actual media on a nice external portable drive. Usually I just yank it, but then I watch the drive letters run themselves up obscenely high before I…

  • Step Seq

    A few days ago I discovered an amazing music program hosted on the game site Kongregate. Apparently the creator, the guy who runs QuickFingers.net is in some sort of contest for a LOT of money to see who can make the coolest music game on that site. Well, his was on top when I checked a few days…

  • Faster Internet is (at least for now) better

    We’ve just gone live with our newly activated ADSL connection. As of 5:00 this evening, I was able to plug in the aforementioned modem that we bought on Friday and successfully connect to first Qwest’s initial login page, then, well, everywhere else! Of course, everybody’s test to see if they’re connected is Google. Well, not…

  • Idea for New Computer

    So we’re having this BIG thing at church where a group of probably seven to ten guys are going down to Argentina in about a month or so. They’re trying to set it up so that the Tuesday when we’re meeting and they are gone, they’ll Skype us during service and we’ll be able to…
