The "what it can do" is an interesting question. I have a "gut" idea, but you are right in that it should be written down.
No, the have a programmatic state that is separate from the main CPU.
Wow, I have over a dozen motors here and all have at least an 1/8 of an inch.
Even an 1/8 of an inch?
What's it going to teach them? Motor control, programming, operating systems, computer math, electronics, etc.
The only difference is "programming a microcontroller." I'm not sure of the singular value of this.
This is clearly an opinion, you are free to have it, but I don't subscribe to it.
I see a different project.
Maybe.
Why?
It is impossible for anyone to create anything that doesn't reflect their background.
I have a year or so old EPIA 800 board. You can get faster than that these days. I think I sent a link to find the power supply.
I've seen 128M sticks for $9.99us, its insane.
Net boot is very cool, but dhcp, bootp, and tftp is too much to ask of your audiance.
I wouldn't touch Windows in an embeded application.
Cool, what did those run you?
Me neither. Just an interesting note.
I thought it was a neat novelty.

This website will create a boot floppy image for pretty much any network card. I haven't tried it myself but I have seen several reputable websites refer to it.
I think that the adapters were less than $20 per from Logic Supply
The CF disk drive was the expensive one at over $200.
However, with Stuart I was concerned with battery power because I'm not overpowering (24 or 48 volts) and then going down with a DC-DC converter.

Nope. A solid metal for a backing.

That sucks. I'm using much cheaper motors, maybe that's the difference.
It's not a question of cost -- it really just depends on the motor. I have a boatload of DC gear motors, and some have an exposed aramture shaft, and some don't -- I generally go surplus, and you're pretty much stuck with what's available. Sometimes there's even a glut of suitable motors with built in encoders -- you just never know. I don't think I'd assume an armature shaft is available unless you are designing with a specific motor in mind -- or at least have a plan b.

could also hang a few 8255 (or similar) chips off the parallel port to expand it. They are cheap enough.Futurlec sell them for US$3.90 but should be able to get them cheap, surplus.
Could also do the same with some of the usb chips / modules.
