It's usually called an ESC (Electronic Speed Control). Tower Hobbies (www.towerhobbies.com) sells them to the R/C type people. You'll have to spend quite a bit ~$50 to get a good one. I wouldn't recommend R/C products though since they are sometimes very poorly designed. Parallax also makes one that...

Wow, and a Noritake VFD at that. Those are generally expensive HD44780 compatiable VFDs that are quite simple to control. Great job getting that to work. I would have never though to look in modern consumer grade equipment for that kind of high end stuff. They generally all use custom ASICs and chea...

You would be better off getting a laptop or tablet PC and running a stable OS and serving as your non critical instrumentation display. There are lots of software packages that allow you to hook up a gps and display a moving map and all sorts of cool location data. BTW, Don't you have to get FAA cer...

I would say go with a conventional microcontroller (PICs, Atmel, Freescale, etc). The reason being is that FPGAs use a HDL which is somewhat harder to learn and radically different from standard computer programs. Learning to program on a certain microcontroller is probably much more beneficial in t...

The issue with the registration system is that the default phpbb verification image was cracked early on by some OCR geniuses. They figured out how to easily decipher the generated images with very little cpu power (and thus bots can flood forums in a matter of minutes). Email verification does not ...

How about using a Propeller Chip from Parallax? The chip consists of 8 cogs which run 8 seperate threads, each with it's own video generator and 2 counters / plls. This enables full color video generation in either pal, ntsc, or vga. The video generation is actually done in software (the chip can al...

1 TB is way too much space for me. I can barely use my 80gb and 200gb hard drives. I also view the 1TB drives as a risk since new hard drive technology that requires huge amounts of magnetic storage in a small space usually means there are huge dataloss issues. Steve Gibson of grc.com stated that hi...

Many people believe that Google primarily uses the link counting system where if a site is linked to by other sites a lot than it is ranked higher. This is 'proven' by the fact that Google Bombing (http://en.wikipedia.org/wiki/Google_bomb) exists. As you can see, Google lets its system do what it wa...

Google is indeed amazing. I fell in the almost exact same situation except that it was my computer science teacher searching for an answer. She was searching for how to add a delay in a vb program and the first result was a code snippet I posted on these forums. Needless to say, the post was printed...

I have used the magazine paper method numerous times to make PCBs. I have used them on projects ranging from through hole parts to surface mount and the results are pretty satisfying. I have a pack of staples brand photo paper that has a paper backing and isn't porous plastic. I have heard this is t...
