What we used in school was an emulsion of water, oil, vinegar and aluminum dust (waste from the grinder, replace with graphite or any other metal dust or leave...
Hi James, ... Thomas Skinner sells a product called Anchor Lube which works well as a tapping fluid and cutting fluid. It's a lime green color, and you can buy...
Hi Jamie, I found some decent cutting fluid for aluminum at the regular hardware store (I think I was at Rona here on the north shore when I found it). It came...
For light duity machining, at work, we use Rapid Tap for steel, and A- 9 for Aluminum. Tapping fluid is fine for light lathe/mill work since you are cutting...
Hi For a while I've had an interest in radio control planes. With electric aircraft it would be very helpful to have a light (1 oz or less), small (about as...
HI Jamie, ... Creating such a device should be pretty straight-forward. You really need 3 components to do it: 1 - A microcontroller (like an ATMega8 or...
Found this over at AVR Freaks, its a well-written document re: the C programming language. Its not specific to microcontrollers (or any specific platform) but...
... I'll add a link to that to the VRC page: http://www.davehylands.com/VRC-C-Programming/ -- Dave Hylands Vancouver, BC, Canada http://www.DaveHylands.com/...
Wow. Those look pretty cool, too. Speaking of less expensive solutions, are there any really economical ways to interface a microcontroller with USB or...
Hi Clinton, ... Check out http://www.edtp.com/ Or for the ultra-simple interface, there's the lantronix XPort, which is essentially a serial to ethernet...
Hi, I've put up a couple of new web pages: The first one deals with servos. I hooked up an encoder to see if I needed to do any calibration, and the answer is...
I think the price is actually OK. Yes, you can get the other boards for less money but they usually don't have power electronics on them. Additionally to ...
Hi Markus, ... I don't think that will ever happen. It only has 256K of flash and 64K of RAM. You could do uC/OS-II or something similar though. -- Dave...

We are starting to look at replacing the PIC16F877A with the PIC18F4525. This would give us much more programming space and allow for some verbose RS232...
Hi Group, there will be a Big Computer Swap Meet on Sat Aug 5th at the Croatian Cultural Centre 3250 Commercial Dr, Vancouver. Hours 11am-4pm Admission $3.00 ...
Has anyone tried any of the USB AVR programming cables yet? I have tried unsuccessfully to add an LPT1 port on my new computer but that hasn't worked (not...
I use an AVR JTAGICE II to program Atmel chips it is great for programming and debugging, it has both a serial and a USB interface. The only thing is they cost...
Hi Lee, I picked up one of the Atmel USB programmers from Digikey (about $40) and it works great. It won't emulate the SP12 interface but it does plug into the...
