  • 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…

  • Pentax Camera Accessories – The Expensive Joy of Brand Loyalty

    Last April, after months of researching and stressing over whether or not I should (or could), I finally bit the bullet and spent $1300 on a nice 24Mpx Pentax K-3 DSLR. This is a super camera that I really have been enjoying and getting some high quality photos with. Most of all I like the…

  • Expired Domains – A Headache (but a learning experience)

    Hey all! It’s been a few months, I know. But I wanted to share an experience I had with my recent domain name headache. So as you may or may not know, I’ve owned ppsstudios.com since May 2013. I purchased it via Google Apps which in turn set my registrar to eNom. Both are useful services and work…

  • Finally! An internal DNS server that works (for me)!

    So it’s been much too long since I wanted to do this, but thankfully, I have finally discovered the solution for which I can serve up my own DNS server for internal LAN things, but still have an external host that administers my public website! My scenario and quandry was this:

  • OpenVPN

    New project at work! Setting up OpenVPN. It’s great fun…except when it doesn’t work. I love the Windows interface for setting up the Server. It’s straight-forward, and following the tutorial at http://openvpn.net/index.php/open-source/documentation/howto.html works like a charm. Setting up the client is just as easy, and the connection can be made in a matter of minutes.

  • Ruby on Rails – Success kinda!

    Okay. I’m totally going to try this again, just to see if I can’t figure it out. Ruby on Rails – A ruby based framework for web stuff. Basically, I haven’t a clue, but I’m going to at least try to get it running on Windows and make some rudimentary website things, just to see…

  • IFTTT

    IFTTT – What in the world!? I just discovered this this morning while once again searching for alternatives to Google Reader, since it’s dying in about 2 weeks. I tried Feed Demon at home, but it just didn’t cut it; half of the problems being that it was yet another application (and a memory hog…
