Wireless Tally for JVC GY-HM790 cameras: Part 3

Part number confusion As I am currently working on a project that involves XBee modules for wireless data transmission I had to look for the best type of module. There are a dazzling amount of different versions and plenty of websites that explain the the different lines of modules (Series 1, Series2, Pro vs normal versions,…). It was much harder to match the version and antenna type that I needed with the corresponding part number, and that is what I needed to order the correct one from suppliers such as Element14 and Mouser.

Wake-on-lan (WOL) bash script on router running DD-WRT

Introduction After setting up my router to run dd-wrt I’ve used PuTTy to ssh into the router to start my desktop machine to work on it through a RDP session. After spending months looking up the correct MAC address in my phone and typing the commands by hand I finally took a bit of time to write a small bash script on the router so that I could simply run the script each time I needed it.

Ubuntu Server - setting up ZFS (part 1)

Introduction For a while I’ve wanted to learn about Linux, the way the OS works, what can be done with it, if it’s reasonable to change to it as my main operating system… As well as dual booting Windows 7 and Ubuntu 12.04 on my laptop I thought I should try and set up my home server running a Linux distro. This way I’d be forced to learn my way around the command line, setting up a system to run smoothly without the need for much maintenance.

Dive light LED conversion

Introduction About two years ago I bought a Hartenberger “Maxi Compact” dive light for about €60. As this was a 10 year old dive light with a halogen bulb and a well-used battery pack I think that was a fair price. Anyway, the plan was to use the housing for a modded LED light. At first I just made a second battery pack, the first one was just (not) enough for one dive with the original bulb, so I needed a second one and charge one pack while diving with the other. Also bought a Graupner “Ultramat 14 Plus” battery charger as this was an affordable charger that can be used for a variety of different chemistries, but best of all, it has a port that allows for cell balancing. As I was using a 6S NiMH battery pack, that was a feature I wanted to have.

Mares Dragonfly BCD cleaning/modding

Warning: salt, corrosion and dirt up ahead Introduction Since I began diving about two years ago I’ve mostly rented gear whenever I needed it. What I like about renting things is that you get to try different brands and models, and little by little start finding out what you like/don’t like/need/want/hate about certain gear. You also get some time to figure out how things work and what kind of preferences you have. Diving equipment isn’t cheap, but taking time to shop around can get you a significantly cheaper set of gear.
