TI LaunchPad Stellaris and Anaren CC2530 Zigbee BoosterPack kit

I recently got the chance to evaluate the Anaren AIR CC2530 BoosterPack Kit, which is a ZigBee eval platform for TI’s LaunchPad products, i.e MSP430 and Stellaris. Kudos to the good folks at element14 for providing the kit as part of their RoadTest program. The review is found

Netgear RN312 firmware upgrade 6.0.6 to 6.0.8

Firmware 6.0.8 just became available for the x86 based Netgear NASes. Interestingly enough, it is called “firmware” version, but to me (and others familiar with electronics and embedded systems) a firmware is low-level software running directly on the CPU/MCU. Maybe there are such components in the

tmux on Netgear RN312 NAS

If you spend any time at all at the Linux command line, you need tmux. Period. It makes you orders of magnitude more effective, there’s just no excuse for not using it. Given that the RN312 NAS is x86 based and using Debian Wheezy, there’s an already compiled

htop on the Netgear RN312

Just a quick post on how easy it is to set up the invaluable htop package on the Netgear RN312.  For those not familiar with htop, it’s a super-powered process monitor, way way better than the old legacy top command. Nice stuff, must have. Turns out the pre-

CrashPlan on Netgear ReadyNAS RN312 - hello!

Edit: Installing according to the instructions below works, but it does place CrashPlan’s log and cache files on the very size constrained root partition of the ReadyNas. Especially the cache files will quickly fill that partition of you have lots of files. It is however easy to move those

Superprobe meets vintage multimeter

One of the first tools I built myself many, many (decades!) years ago was a logic probe. At the time things like yellow LEDs were still a bit rare and cool, but this baby had both red, yellow and green LEDs to indicate TTL logic levels. It was a true

Reverse engineering Macbook Air FaceTime camera, part 1

A severely cracked 13″ Macbook Air display came my way some time back. The LCD panel was obviously damaged, but it would be interesting to see what makes such a great display tick, and maybe parts of it could still be used? I believe the display came from a Late

Smoke tester from Dangerous Prototypes

A while back I got a free PCB from Dangerous Prototype’s Free PCB program. It’s a nice little board designed to provide easy current monitoring during prototype stages of a project. Features include over-current tripping with visual indication, as well as dual 5V and 3.3V supplies.

iTerm2 + tmux + Fish = looks great!

If you spend any time at all at the command prompt in OSX or other Linux-ish systems, tmux is a must. Basically it gives you persistent shell sessions, once using it you’ll wonder how you ever got by without it… For OSX the easiest way to get tmux

Compiling Zabbix for small headless server

Turns out the Bubba2 (and of course Bubba3) can run latest version (2.0.2) of Zabbix quite ok, at least when only monitoring a handful of servers. I created a brief installation instruction for bubba here.

How to monitor broadband uptime

After moving to a house a few years back we ended up in a situation where ADSL was the only option (aside of mobile broadband, which is not really a realistic option if you plan to do a fair amount of computer work from home) available to us. However, the

tmux for bubba2

There are various replacements for the traditional screen command in Linux, Byobu and tmux being two good ones. Byobu is good, but after trying tmux on various Linux machines I really wanted it also on the Bubba2. As tmux doesn’t seems to be in the bubba2 or etch repositories,
