Sprite_tm is a big FPGA fan and he was always looking for a nice project to polish his VHDL skills with. Luckily the company he’s working for decided to clean up storage and throw away some broken PCBs and that’s how he got some old FPGA hardware. “…To control all that, there was a XC2V1000; a somewhat aged but quite large Xilinx Virtex2 FPGA. Because most of its IO ended up on the various headers, this board could be easily re-used as an FPGA development board.”
555 Contest: Welcome!
“You’ve got 8 pins…and one shot” And since we needed more room in the title bar, we decided to put the shirt we made for the contest on the front page. We decided to put some designs on Zazzle to raise money for engineering education charities and have some great memorabilia at the same time. 10% of shirt costs will go towards charity (the rest goes to overhead of us not having to bulk order or ship to anyone–the cost of easy logistics).
Tom Lehmann's NY Style Pizza
Today, I made yet another pizza based on Tom L.'s NY style pizza dough recipe. This time, I decided to use a hydration level of 60 percent, and to use an amount of yeast (IDY) at the upper end of the range called for in the recipe. It may be recalled that in prior efforts I used hydration percents at the lower and upper ends of the range (58% and 65%, respectively), and yeast levels at the lower end of the range (about 1/8 t. IDY) and far outside of the range (about 1 1/2 t. IDY).
Arduino Shield List
Arduino Shield Bounty I need more shields for the list! If you submit a new shield that wasn't already in my database, I'll send you a Freetronics ProtoShield Basic . Sick of trying to figure out which pins are used by some obscure Arduino shield?

We’re still looking for submissions for Workplace (and now Work bench ) of the week. If you don’t, we’ll keep posting pictures of Chris in silly hats in my lab. Please email or leave a comment on the WOTW page !

50 Things Everyone Should Know How To Do
Self-reliance is a vital key to living a healthy, productive life. To be self-reliant one must master a basic set of skills, more or less making them a jack of all trades. Contrary to what you may have learned in school, a jack of all trades is far more equipped to deal with life than a specialized master of only one. 21. Parallel Park – Parallel parking is a requirement on most standard driver’s license driving tests, yet so many people have no clue how to do it. How could this be?
The old inkjet printer had to go. Got two nice stepper motors out of it. I don't like the noise and dust from a rotating cutting tool, and became interested in budget lasers. In my search I've taken a good look around on Ebay, and found several "power lasers". After some investigation, they are identified as 200mW red laser diodes from CD- RW or DVD-RW drives.

Getting samples
It's hard to go wrong with free. Parts manufacturers are often more than happy to ship you, for no cost, a few samples of their merchandise. They often ship within the week, sometimes the next day, and with free 2-3day FedEx/UPS.

The reason I want to know is I'm curious what it would take to build something similar. A long time ago I saw a student project doing exactly this, but I'll be damned if I can find the site again.The Unwritten Laws of Engineering - October 2010 Issue
