American corporations these days, if I may understate, don't seek employee loyalty. IMO the root cause is that the CEOs work on contract as a rule, rather than salary. Americans these days, if I may understate, aren't loyal to their employers. Forgive the possible flame starter, but it used to be t...

There should be a peer-review process that should happen before articles get printed. I realize this increases the cost of the project, but the benefits would be enormous. The peer review would work like this: "Hey friend, here's my article, here's the parts you need, build this using nothing but wh...

Radio shack e-fires 400 workers

The Atlanta Journal-Constitution is reporting that RadioShack has notified 400 workers by e-mail that they are being laid off.

As a matter of fact, that bulb is subject to intense vibrations... the ceiling it is mounted to is the floor to the landing for the stairway upstairs. And I have a very energetic 5 year old. Thanks for the advise!

Jollyrgr: Interesting... I have one fixture in my house that burns out 1 light bulb every 3 weeks (I originally used regular incadenscents, now I leave it empty). P.S. I forgot to mention above... 10 years ago I bought some of the ccf lights and at the time felt they were convenient for a garage or ...

The Bulb of the Future

Interesting article on slashdot... http://hardware.slashdot.org/article.pl?sid=06/08/29/199228 "if every one of 110 million American households bought just one [CFL], took it home, and screwed it in the place of an ordinary 60-watt bulb, the energy saved would be enough to power a city of 1.5 millio...

Interesting line in there: "If you run a turbine with a gallon of gasoline, you can generate enough electricity to run an electric car 110 miles". I've wondered about this... why don't you see more people making plugin hybrids? (being defined as an electric car designed to be plugged in overnight b...

Vex robots

Radioshack is selling the vex robot kits for 50% off. I couldn't resist... bought the starter set and a few extras. If you decide to get it, make sure to get the power pack. Also note the "programmer pack" isn't included, that's separate as well. 6-7 hours into it we've built our third robot. "We" i...

OK, I'll try it. I'll order a couple extras in case I let the smoke out of one or two. Then I can ask more specific questions after I get a little first hand experience. I sent an e-mail to spark fun to see if they have negative voltage regulators. It seems none of the hobby-oriented supliers carry ...

I'm insane... I'll guess I like microcontrollers and try to figure out a way to put one in every project. I'm not going to use them on this project. keep it simple. Here's a switcher: http://www.sparkfun.com/commerce/product_info.php?products_id=317 It says that it can take in 3 - 40v and put out a ...

OK, I had originally intended to have this built by now rather than talking about it (no really!), but a few unexpected things have come up. Also, this weekend is a family trip so I'll toss out one other idea I had. I am not that familiar with analog stuff, but I am getting better with microcontroll...

Didn't Engineer1138 build the roman black BTc device? http://www.romanblack.com/picsound.htm That should be able to hold quite a bit more than a typical encoding solution won't it? He lists 17sec = 32KB which is a little under 2KB/sec. You could fit 18min in 2MB. Don't know where to find 2MB of flas...

I've never used a switching regulator (outside of a car)... any good starting points you guys can recomend? Also, here was my idea (simplified) for the power supply.

Basic power supply concepts

Well, a while back Edd made the statement "Analog is not a bad word." I suppose he's right and I'd like to start understanding analog stuff better. I thought I'd start by making a bench power supply. I'm currently just using a walwart with a hacked cable. I did some searching and drew some schematic...
