  • Homemade propane detector sequel

    My homemade RV propane detector (see original post) has been working more or less okay since it replaced my ancient, broken Ten-Tek 800a. There’s been a couple of developments since then. First, I found another Ten-Tek 800a unit on ebay (sold as new-old stock, still in original box) which I bought because I’d spent enough time with…

  • Lenny orders a subscription to the Mercury News.

    The San Jose Mercury News just sent a bill Lenny for subscribing to their newspaper! This would be less surprising if Lenny was actually a real person rather than just a disembodied, barely coherent set of voice snippets on my answering machine setup. There’s really not more smarts to it than that; everytime there’s a…

  • Howto setup Network Block Device (NBD) on Openwrt for remote encrypted backup.

    Here’s a quick writeup on setting up Network Block Device (NBD) drivers to attach an encrypted hard drive to a remote Openwrt Wifi router for disk-level encryption across a network, without needing to store the encryption key on the remote system.

(As part of my general telephony weirdness I run my own phone PBX, based on the open source Asterisk project, running on my linux box. I use it for…

  • Repairing an RV Propane Detector

    My old Ten-Tek 800A propane detector on the RV stopped working, announcing its failure with a continuous shrieking from its warning buzzer. It’s the type of detector that hooks into a solenoid-operated valve next to the propane tank so that if the propane detector isn’t happy it shuts off the propane, to reduce the risk…

  • New WordPress Server

    Deciding it was about time I started writing up some of my projects, I’ve spent some time figuring out how to host the WordPress blogging software on one of my servers.  If you can read this post, then the system is working.   To make things a bit trickier, I configured a ‘network’ WordPress system that…
