Power over ethernet, sorta
So we’re still busy decking out the new facility and one of the things we wanted to get up and running is some cheap surplus ethernet cameras to … keep an eye on things and check out whats going on remotely. So I thought I’d go ahead and set these guys up.
First thing up was to make some cat5 cables. I got a cheapo crimper, cable tester, and connectors off eBay. While trying to figure out how much cable I need to run I was thinking about how I’m going to plug the cameras in to supply power. They have wall warts with barrel jacks running 12 volts. I started thinking about how power over ethernet works and thought I’d try to see how I can do the same thing to run the power to the camera. These aren’t POE cameras so the idea was to only half crimp the connectors, and use the unused pairs to run the 12 volts.
Here is the layout of how cat 5 cables should be done. Credits to wikipedia.
So there are 2 color coded standards for crimping cables, but oddly enough, the ones we care about are blue, blue/white, white/brown, and brown. Pins 4, 5, 7, 8. These pins aren’t used in 10/100 connections, however if it was gigabit then they would be used. So the unused pins are the same on both standards, so I just chose the first one.
Roly Kit – Amazing Retro Storage for Makers
The Roly Kit storage box. I vaguely remember seeing these things from my childhood, sometime in the 80′s, but that was a long time ago. I think I had totally abolished these things from memory…until a year or two ago, when one of our members brought one to hack night filled with lots and lots of electronic components. We’ve all used the tiny drawers for parts storage, like the ones on our workbenches. I even have a more modular one that has a handle to carry it around, but nothing compares to the storage capacity of the Roly Kit.
After admiring the sleek rolling storage for so long, I finally decided that I had to have one. Doing a little research, it appears these things were invented sometime in the 70s, and made by a company in the Netherlands. Sadly, the only reliable place I’ve seen them for sale is eBay, and occasionally a thrift shop. They appear to come in a few colors and 2 different sizes (‘big’ and ‘medium’). If you’re a maker and need a nice travel friendly holder for all your resistors / caps / knobs / switches / 555 timers, I recommend you snag one up too.
Another RedBull Mystery…
So it appears the BullDuino has another hidden morse code message on it. We smell something wargamesish.
— UPDATE —
Looks like the decoded message is ‘Wouldn’t lou prefer a good game of chess?’ …. is LOU a typo instead of YOU ? L is inverted Y in morse code… could be. Or could be a clue.
This is obviously a quote from (or a play on a quote from if Lou is real) from WarGames. Hmm.. 1983… Global Thermonuclear War. Joshua/WOPR WHAT DOES IT MEAN?
Redbull Creation 2012 has started!
Hooray for Redbull Creation 2012! So it all starts with this Bullduino provided by RedBull. Here are the initial unboxing pics. So far it appears to be an Ardunio Uno layed out on a cool RedBull logo pcb. I’m going to investigate deeper…
