I bought 3 HC-SR04 Ultrasonic range finders from AZtronics for$5 each!!!

They are really accurate, easy to use, but you can see the side lobes coming into play.

I figured for $5 a piece I'd give them a try.

Because the output is digital there is a lot of "information" that you'll miss, such as the "quality" of the echo.

The way I'd normally do it gives me an idea of what the echo came from, just like watching an old school "fish finder" on a boat.

The other surprise I got was my free sample from Coridium!
One of these!

I was thinking of making a shield for it!

Overkill?

Hell yeah!

a 50Mhz ARM sitting on an Arduino seems like a good idea!  8)

Being as the LPC1114 is the only DIP ARM around I'd say it will be a popular chip. You can get in a TSSOP as well and that will fit inside the DIP footprint IIRC. So you could make a board that allowed for PHT and SMD, one for hobbyists/protoyping and the other for production.

Coridium have loaded a BASIC interpreter, maybe Picaxe had better look out. I'd post about this on their forum but they are very touchy about posts regarding other products and they get summarily deleted.

It's not a Basic interpreter!

The HackaDay article was really misleading, it runs compiled code.

HackaDay seem to be going down hill at a rate of knots!

The "just plug an FTDI cable in and pretend it's 1986" was a crock.

In the comments section the bloke from Coridium address's a few of the claims the writer made.


Graynomad

Yes I see, it's a compiler.
