Re: Microcontrollers

A common way in hobbyist robotics to get variable speed is by modifying a servo to act as a speed controller. It requires a bit more advanced programming to control than other methods, but can allow for very fine adjustments in speed. Actually, that whole website is a good resource for robotics. I d...

Re: Society for the Discontinuation of Game On

If I may add my experiences with KSU's Programming Contest : It's similar to iwonder's version of the contest, but with a slightly different design and purpose: the day is divided into 5 rounds, with a single problem per round. Two-person teams have ~30 minutes to write a program from scratch in a l...

Re: Your Daily Random Comment

Just tested this: 1. pick a random wikipedia page 2. click on the first link in the article not in a header, italics, or parentheses 3. repeat step 2 on the new article if this is done enough times, the chain will end up at the article "Philosophy" almost invariably, save for a few cases where it ge...

Re: Sounds of Music B

I have this event on Saturday, and I was wondering if we are allowed to use a guitar pick. My instrument is a cigar box guitar. Thx :) Yeah, agreed with Z. However, it isn't very difficult to make your own pick. I've heard that picks make by cutting up a used credit card work well, and there are pr...

Well, the best thing to do is probably to look up what woods are common for whatever instrument you're building. After some quick research, it seems that the most ...

Re: Sounds of Music B

Sorry for the extremely ridiculous question that I asked recently. :( Well, I received my guitar (medium tension, 80/20 bronze) strings yesterday. I think that the strings' tension will break the PVC pipe on the harp. I am going to drill holes onto the neck and the soundboard and tie knots in the h...

Re: Water Quality B/C

We haven't actually built the device yet, but i will once we do. The build is, as stated above, pretty simple- some sort of multimeter/ohmmeter/something-that-measures-electrical-resistance device, and a small apparatus that contains two metal leads of a particular size and distance apart(it doesn'...
