If you really want to stay relevant to what all the big boys are playing with these days, you'll learn ARM. And maybe a sprinkling of FPGA with an eye to ASIC implementation. Smaller microcontrollers are being used, but ARM is where everything is happening, if you want to base a career around embedd...

If you wanted to swede this, maybe take a plain resistive potentiometer and put an LED out on an arm extending from the base of the shaft. Then cover with a disc of dark translucent plastic. Of course this removes all the advantages of the real thing, while preserving the same look.

They might not be too amazing for prototyping quantities, but I think you'll be surprised if you start working with them on large quantities of assembled devices. It really made me wonder at the retail prices charged for a lot of the electronic products we buy.

Unless a PCB supplier says otherwise, you can assume that their hole sizes are 'finished' sizes. Olimex is the only co. I know of that requires a plating allowance to be added to the drill sizes. Leon That's one of the reasons I quit using Olimex. When all is said and done, you're paying about $1.5...

I'm hopeful that these are resolved, but if anyone knows how to guarantee that x random small office network will have 100% uptime, I'd appreciate your letting me in on the secret (bonus points if it doesn't cost anything). Use straightforward, basic hardware (i.e. a simple DHCP/DNS and some switch...
