alain6870. I'm not currently doing planning on doing PCBs with pre-assembled SMD.

It is something i investigated with Dervish a year or so back. I had a some prototype boards built & I constructed a test rig to fully test them. The quality of the built boards was great, and the price is good if i had a quantity built (at reasonable quantity, almost as cheap as buying the parts at one-off). But I have concerns about how a builder repairs the board if rework on the SMD components is needed, so i decided not to offer them. Whilst boards from me would be fully pre-tested, there's always the chance of a fault developing, or the builder makes a mistake that damages one of the SM components. Builders who would buy pre-assembled boards are unlikely to have SMD rework equipment to repair this, as would someone who is building unpopulated PCBs. I wouldn't want people spending a lot of money on something that they'd have a problem fixing.

The fab have just emailed me to say the PCBs should ship on the 26th, so they should be with me by the end of next week.

Sorry toneburst, i didn't realise you'd posted this. I only got the email notification for your first post.

The control board is designed & tested for the brighter Kingbright SC05-11 displays. Other 12.7mm/0.5" 7-seg CC displays with identical pinout *should* work, though you might well need to adjust the value of the current limiting resistors to suit.

Ah just noticed this!! - definitely up for a set Graeme (most likely 2 sets) - the original Dervish is pretty much ubiquitous in my patches.

EDIT - PS I'll take all the extras too, including the pre-programmed chips. The Yellow Kingbright Screen looks fab!

yup, i'd take a set of pcbs, I 've been looking at the dervish for a while and may as well jump in on a group order.

Are the sv1 chips tough to find?

You can buy the the FV-1 from me as one of the "harder to source" extras (see the "purchasing/build" section in the first post), so usually it'll be tucked away in the box along with the PCBs ;)

I've just ordered enough FV-1's to fully cover this run of PCBs, so I'll have plenty.

Apologies for the lack of updates. The PCBs were delivered at the end of last week. Since then I've built a couple up & they work fine. The windows are very slightly bigger for the cutout in the panel than i'd intended, but thats fine. They'll just need a bit more filing than the Dervish ones do to get them to fit.

I'm most of the way through re-working the Dervish build guide to cover µDervish. Then I'll do the debug doc.

Over the weekend i'll work out prices for the PCBs & extras & then contact everyone who's expressed an interest in PCBs. Hopefully i'll get that done by sunday/monday.


Before i ship PCBs, I'll go through the Mouser carts & update them to ensure all the parts are actually in stock in reasonable numbers. I'll do this at the last minute as i know some 0603 parts are in short supply. Fingers crossed they'll have everything. I just re-stocked some of my parts here from RS & there's minimal selection available from there now.


I still haven't worked out what i'll do about what programs/banks are in the default image/images :deadbanana:
