Breadboarding

I used to love that sort of thing when I was back at Boeing. The H/W contractor would build something and 'throw it over the wall'. If anything didn't work, they'd just say, "You can fix it in the software".

Perhaps you could just buy thin copper tape and cut out the shapes you need?

I think I've seen that before. Still curious how well thin FR4 over a solid plane works, though. Plus, I like etching more than xacto-ing. And etching is easier for really small details, too.

IIRC expresspcb uses proprietary software, and if you can get your hands on gerbers it comes extra. PCBExpress takes gerbers and a drill file, and mails you back PC boards.

Their 'base' service is 1 day, fairly inexpensive, no silk, no solder, two sided only, and they specify the drill sizes (I think there are 23 to choose from, however, so unless you need precision holes you'll get something close enough).

So you can pretty much use your regular design process and tools, even to the point of sending the exact same gerbers to a full-service board house when you're done with PCBExpress.

I can't imagine that some enterprising eastern European entrepreneurs aren't doing this now, at least until their countries are overrun by Russia.

Do you need to implement control loops in software?
"Applied Control Theory for Embedded Systems" gives you just what it says.

A bit fiddly for DILs.

And for TVSOPs too, but like I said, I prefer etching ;-)

Vectorbord used to make one, but I haven't been able to find them - presumably, there wasn't enough demand to keep making them. )-;

Sorry for the teaser. Rich

If you'd sent your layout to one of those quick-turnaround board shops when this thread started, it'd probably already be done, and you could be refining it now. ;-)

Q. How many engineers does it take to change a lightbulb? A. None - we'll fix it in software.

Are you crazy?? I can't afford kapton tape! ;-)

But seriously, is there a supplier for kapton that's not $25-40/roll?

Ebay maybe?

How long will a roll last? Is it worth worring about the cost?

On account of budget reasons the design's not yet finalised actually.

It depends on how much you want:

About $15 a 36-yard roll for 1/2" is easy (eg. McMaster), there are some offshore sources for $5/roll landed but I'm not sure it's actually Kapton (or generic polyimide) but maybe amber colored polyester.

Farnel can't be far away from you, and a single board costs a bit over ten quid.

Why not order one (order code 1201481 - see above) and see?
