Title: Raspberry Pi anyone?
Post by: mtnbkr on February 29, 2012, 01:28:46 PM

I missed the launch, but put my name on the list.  Dunno what I'll do with it, but it'll be fun to experiment with such a small form factor.

Nope. Don't much care for raspberry.

Probably 1000X more "powerful" than the IBM 1620 on which I cut my teeth.

The pic in the link reminds me a little of my old SDK-85.

Assembly language only, hex keyboard.

I used one of those, too. It's not Assembly language, though - Machine Language!!

Assembly was an order of magnitude more complex; MOV xx yy. That sort of thing.

Really interesting concept.  Reminds me of an Arduino

Real programmers code right down on the metal.

I have a feeling this project is going to die for the same reason the Touchbook and Pandora did.

That is, geeks are really bad at business; they don't know how to market, sell or price a product. The result is a never-ending series of revisions, pushed-out release dates, pre-orders, and they never actually ship a worthy product. Usually this is because they under-price the product; charging what they think it's 'worth', or what they would like to pay for it, rather than what the market will bear, and thus they don't get enough early cash flow.

Maybe.  We'll see.  I was able to place an order today, it should ship April 3rd.  

It's powered via a micro-USB port.  I think I'll connect mine to my PC's USB and power it that way. :)

I think I even have an appropriate case at home.

Hmm, it runs off 5v, I bet I could rig up a tiny UPS inside the case along with it.  Maybe a LiPO battery...

Edit to add: Found my UPS, http://www.amazon.com/Duracell-Instant-Charger-Lithium-universal/dp/B002FU6KF2/ref=sr_1_1?ie=UTF8&qid=1330812174&sr=8-1

I bought one of these when Woot.com had them for $10.  I need to check the output ratings, but I'm quite sure it'll be more than enough to power the Pi (needs 5v@500ma if you're going to run other USB devices).  Plug the Duracell into the wall and the Pi into the Duracell and you have an instant UPS power supply. :D

we had built one like this using an 8086 processor.  we even burned the boards.  that was one of my favorite school projects!  (why didn't i persue a career in electronics?)
