The problem with letting the spam posts stick around is that it gives them what they want... They honestly don't expect us to click the links, but they'd love to have google boost their page rank so that they get higher positioning in the search engines from people who are searching for that crap.

Interesting looking CNS plans

I saw these posted on make: http://www.makezine.com/blog/archive/2007/01/cnc_router_plan.html The plans seem highly regarded as a good first cnc machine. I'd love to have one, and I'd love to make it myself. I don't have a table saw, but I do have a router and a miter saw... seems that's enough for ...

The title to this thread gave me flashbacks to the beginning of "Empire Strikes Back." Wasn't DV trying to find the rebel base and take out its shield generator?

SCORE! danbob, awesome link. The winter sale has them for $7.50! And, he's got surface mount component grab bags, too. Phil, I so agree... I recently started soldering surface mount parts. Now that I'm confident and comfortable making my own boards, surface mount is so easy not to do it. The only pr...

dealing with small drill bits/holes

I've finally accepted Eagle and started using it for my boards. I've got a complaint, and that is the pads on many through-hole parts are too small to easily drill. I have tiny drill bits - I picked them up at Radio shack, of all places. Same as the ones you get at the hobby store, but at RS you get...

Holy cow! 5GB? It seems like yesterday when the Intel 4004 was invented. Back then, small computers occupied a half-rack and you were amazed at the storage capacity of an 8-inch floppy. Well, I did have a TRS 80 (coco2) that had a cassette tape drive, but Dean, you have to admit, 5GB made it mainst...

Use a tool such as Spinrite to check the real geometry. Commonly the number is faked in order to trick the computer into seeing the right capacity.

I could be wrong, but I remember the day of 5 -8GB hard drives, all kinds of tricks were used to get the numbers to come out right.

Can't wait to see it. Calling back to the thread from a few months ago regarding the ultra-capacitor car power supply, the energy density here is (theoretically) amazing. What happens when one of these things "Vents with flames"? I keep hearing how new technologies are just around the corner, but I ...

Miguel, I have a circuit similar to that on my breadboard right now... I run two steppers and instead of the 4017 I use a PIC that simply does something like: rb0 = 1; rb4 = 1; wait rb0 = 0; rb4 = 0; rb1 = 1; rb5 = 1; wait etc. I used it to experiment with different voltages/delays to see how fast t...

Wow, that is tiny. I mocked one up in Eagle (still trying to learn this prog) and printed one out to see how hard it would be. This uses relatively wide traces so on a bread board is two rows wider than dip on one side, and three rows wider on the other. Still, that would be a bear to solder. Here's...

I used to repair laptops and needed small drivers (for example, torx #1 used on thinkpads). Sears had some nice small drivers that were easy to grip and hold. Mine were black with a red cap that rotated (which was very useful).

A technique for stopping spam bots

I've recently been getting 100's of "trackback" type spam coming to my blog. I got fed up, because it was absolutely filthy spam and I could not stand the thought of these guys using my blog to boost their search engine ranking. I did some searching and asking and found a PHP script called " bad beh...

Yeah, both of those are icsp only. These boards I've just created are ICSP but to be honest, I'm most familiar with programming using dip sockets. Phil (and others): When you layout your board, do you add a connector for an ICSP header, or do you have some way that you can just clip the icsp cable o...
