Hi All,
Saar has come up with a very cool board design for a kit which is going into the OSHCamp 2013 / Wuthering Bytes goody bag:
http://boldport.blogspot.co.uk/2013/08/new-board-wuthering.html
This is essentially Ihsan's LittleWire board, re-spun via Saar's PCBmodE, for added wonky track goodness along with other artistic flourishes.
Feedback is welcomed and in particular on functional considerations!
Cheers,
Andrew
Hi Andrew,
This is wonderful! As expected, Saar has done a wonderful job of re-creating the Little-Wire. Sadly I won't be able to make it to OSHCamp this year so I'll stick a couple of these on my next PCB order.
A minor suggestion -- and this is mostly because I am paranoid about power -- would be to add an extra capacitor to the USB power net, to act as a reservoir in case the host is noisy. There are some really low profile 22-33uF electrolytic capacitors that will do the job nicely.
This is primarily for the case where you use LW to power external circuitry. Since the intended use for a LW is a debugger/development tool, eliminating the possibility of noisy power is a good idea (one less thing to worry about when you are bringing up a custom design!).
Cheers, Omer.

Ah, that is a shame, but hope to catch up at an OSHUG meeting soon after.

Many thanks for the suggestion!

Right, good advice...

Hi Omer.
Thanks!
I agree that a beefier input cap would make the board more robust. I'll add one somewhere ;)
cheers, saar.
