I had a lot of trouble getting the compass to work with the wiring.org.co board and I think that tell me something. I just couldn't get it to work using the...
Folks, If you want to see a LOT of creative and silly contraptions, come to the Mechanical Engineering Course 2011 robot show next Monday December 8 from 2:40...
MAN, this thing sure settles down when you run a calibration cycle on the thing. I double-stick-taped the Wiring board and the compass to a hand-cranked rotary...
... There's no need to show more graphs, but the compass works just great when installed on Trippy! I've got the motors varying their speed, and the thing ...
So, does the calibration get stored in non volatile memory? Once cal'ed it will output cal'ed data when repowered? I am just wondering if calibration is...
Congratulations on getting the compass working on Trippy. In general tho a couple questions: Is the calibration intended to be done to take into account and...
... The calibration is intended to compensate for the hard-iron effects of the structure its mounted to. You should perform a calibration-cycle every time...
First of all, congratulations Alan! Its always a big rush when something you've battled with far too long suddenly succumbs to your will! ... A few reasons I'd...
The guy said that code STILL says to ground through the water pipe, even if you have the 8 foot rod. I pounded in the 8 foot ground rod outside of my ...
I was told by my plumber that code states that you must have a continuous conductor from the water service entry to the electrical box. I think the idea is...
I believe that the code says something like: Attach each supplemental ground as if it were the only ground connection. ________________________________ From:...
This is one of those topics that can go on for a long time. Here is some things to keep in mind 1. The more grounds the better. This is because the better...
I think the code says that you have to ground strap your input and output lines from you water heater together. Jeff ________________________________ From:...
I think the reason they want to you tie all of your water piping together and tie them to ground is incase (somehow) this piping becomes energized. They...
When I lived in Germany a friend of mine was complaining that they got an electrical tingle when they were in the bathtub and touched the handle to turn on the...
I am planning to buy 20 pieces of the Solarbotics GM9 with wheel kit. At that quantity, each one is $7.58 plus a share of the $14.00 it costs to ship it...
... http://www.pololu.com/catalog/product/188 It's twice as fast as the GM3's that are on my line follower (metal base from Allen) I guess I could buy a pair. ...
3. The hot water heater I installed a couple years ago has the 'dielectric' insulated couplings on both the input and output sides, and it came with them....
I now have the plumbing grounded near the electrical box. I no longer have 3 Amps coming in from the street on the water main attached to my house because of...
I think you are supposed to strap them together for this purpose. I was looking for this in the code last night, but I did not find it. But I swear I saw this...
From http://www.misterfixit.com/hotnot.htm Here's a basic description of how the electric power gets to your house. Most homes are supplied with a 220 volt...
I am not intending to buy these from Pololu, I am intending to buy them direct from Solarbotics. When buying more than ten pieces it makes better sense.  I...
... I'll buy 4 kits (preferred wheel color order is red, blue, yellow, black). I'm planning to be at the December meeting, and I can pay either then or earlier...
Video from a symposium on memresitive systems held at UCB has just been made available on youtube. I've only begun watching them, and the first one looks like...
