Group Update and interesting items

2009-11-27T13:27:35Z

I know it's been a little quite on the group recently apologies, I've
been up to my neck in both work, research and DIY at home..

Looking to arrange a meetup shortly (sorry been slacking), if you have
any ideas let me know.

Here are some interesting items I thought I would share:

Farnell and Microchip have a training event on the 1st December which

They have also trying to get the RepRap to build its own circuitry :

Paul you might also be interested in MakerBot :

It doesn't have the same lofty goals of self reproduction but it is a
very good 3d printer that was a fork from RepRap.

Just in case you have not seen this fab project. I had not. Have
now. Please Santa...

If you can print with cement then you might be able to print a
conductive paint, hack an inkjet cartridge a give it a go on your
inket printer!

This stuff is spray gunnable.

Adrian,

Yes, it seems that fixing demisters etc. is currently the main way
that conductive paints are sold. I've just bought some but haven't
tried it yet.

Thanks for the replies Al, Adrian

Yes. Kits like snap-circuits are one of the inspirations. It should be
easy for kids to play and learn electronics with something like this.
And similarly the little-bits project is heading in the direction I
want.

But the price and form-factor is still wrong. The components need to

How about using magnetics to assemble the components like this

But more 2D of course, would that be permanent enough or our you thinking

Actually I nearly forgot you can actually get conductive glues but I have
never used them, but remember reading about them.

You could use vero/strip board to make permanent your breadboard design
without going having to design and create PCBs, but that involves soldering
.

Getting good conduction could be an issue, especially from the stickers to
the conductive ink/paint. The stickers would need metallic edges (foil?).

Hi Phil,

I'm not quite sure what you mean by cushioned stickers, but I wonder if
the foam mounting board [1] you can get from art supplies shops would
work as a breadboard replacement? Then once you've stuck all your
components into it, would the rear window demist repair paint [2] you
can get at places like Halfords (I think, I haven't looked for it for

Hi everyone.,
Here's something I've been thinking about for a couple of days. What
do people on this list think of the technical feasibility of this?
Prototyping circuits is too hard. Or rather, breadboard is OK; but
there's no way to keep a more permanent copy of an experiment without
soldering up a real board. I'd like some intermediate option.
