Nice, but could you use cotton wool instead of that other type of stuffing which I've never heard of?

Starting to learn KiCad.
The clearest (step by step tutorial) I`ve found is here
http://store.curiousinventor.com/guides/kicad/

If you are thinking of selling your circuit boards in the future and don`t want to spend money on software, use Kicad.
Warning long video! Part1 45m, part 2 over an hour!


I also watched this

and was quite impressed.

Diptrace also has a free version (not for profit) version, no size limit but 300 pin limit.

Portable Amiga Mod Player! smiley-grin

I still have a collection of my fav amiga mods stored away in the depths of this hard drive somewhere. smiley

Yes, that's the total width of the display, each number is about 20mm high.

Like this? (6" Display)

The photo does not do it justice, it's a nice large display.

I guess its possible using custom characters on a "normal" 4 line display?

Thanks for the replies.

I'm looking at this circuit (my application has nothing to do with doors though) smiley
http://www.npeducations.com/2013/01/laser-light-based-door-opener.html
The op amp in this case is used as comparator, I could probably do away with this and feed the output of the transistor to the arduino and do the same in software?

LM324, LM358, other?

It will be for a photodiode amp circuit.

Thanks.

Is not the MakerBot platform arduino based?, I think they made quite a bit of money out of that.

Very nice clean design.
41  Using Arduino / Sensors / Re: MSI Barcode Wand Connections? on: June 15, 2013, 03:55:13 am
I did some measurements on the connections using the meter Diode function.

Diode Test on Meter
Red +  White -   1316
Red -   White +   574
-------------------------
Red +    Black - 1326
Red -    Black + 1360
-------------------------
Red +    Shield - 1315
Red -    Shield +  575
-------------------------
Black - White + 1579
Black + White - 1938
-------------------------
Black - Shield + 1579
Black + Shield + 1938
-------------------------
White + Shield -  001
White - Shield +  001

Blue wire has no connection and is OC.

I would have expected Red and Black to be power, with the white wire to be (TTL) output.
But it appears from the above connections that white is connected to shield, which makes no sense to me.

Comments please.

Yup, a big cardboard pointer stuck to a (decent size) servo, and you could make a big analogue style meter showing the wattage.

Or try another utility like the first one here

see if Autoit will read the text from that.



45  Using Arduino / Storage / Compact Flash Interface? on: May 27, 2013, 02:43:14 pm
I have quite a few Compact Flash devices here, memory wi-fi cards etc

The breakout board sold by Sparkfun
https://www.sparkfun.com/products/195
has been retired, is there an alternative to this, and are there libraries to work with compact flash style devices like these?

Thanks.
