I screwed up with getting the wrong type of crystals. But my test erupter works fine now I replaced with stock xtal. Now I await a new shipment of xtals.

On the resistor front - damn I wish jaycar stocked them instore Sad

Also I found with the xtal's - either flipping them and using a fine tip iron to add a little solder (or putting a little on the pads) then placing them on the board and using a heat gun to melt the solder works great.

EDIT:

An idea about getting enough power to a stick:

Anyone tried using those dual USB cables commonly found in older external 2.5in HDDs? Obviously your USB hub would be then out half their ports - but maybe a neat way to run it without screwing about with more indepth modding.

And to the person who posted the melted PSU - how random! I just had a dream last night where my pi's case melted like that!

Jaycar? you must be aussie.

im in Melbourne and have spare resistors and a few spare crystals. but RSonline sells packs of 50 resistors for $2 delivered if you can find the right brand. I think they were listed as 4c each min 50 units.

delivery built into the price and they were here in 2 days. cant complain.

as for powering I find im just putting less per hub atm till I can get new power supplies. so instead of 5 I might get 4 etc.

Haha yeah - I'm Aussie. Used to manage a DSE back when they actually sold components, then we went on our own and used Farnell, Electus and a few others for component supplies. I miss those days of being able to walk into a shop on a saturday and get everything you need right away.

I did an order with RS after my last post. By the time I am back home on the weekend I'll have the xtals, resistors and a few more erupters. I have found an interesting 5VDC fan and heatsink combo that I could pair two erupters onto one board. And they are only about $8. I doubt I'll bother though and just use a big heatsink row I have already.
