Just a quick update.
I have discovered that the flickering issue is not entirely my fault. Some are certainly my fault (as a result of the new spring - any driver 1 drivers I replaced were
definitely because of the spring problem) however some appear to be dodgy drivers straight from the factory. The affected drivers are certainly the firefly drivers, and by extension the moonlight drivers as well.
I'm not saying they are all affected! Just a small number. The reason I am now stating they could be defective is because I built one drop-in for my father as a gift for his birthday this year. I made
zero modifications to the driver - I left the drive level at 3A and left the stock spring on the PCB. It is now flickering randomly.
So no change in my policy of fixing these drop-ins what-so-ever, just taking
some of the blame off my shoulders because honestly it's stressed me so much that I need to give myself a little bit of positive news!!!!
For those who were affected (and I have a list) I will offer version 2 in exchange for their version 1 drop-in at no cost other than postage. Version 2
will be more expensive so this is a pretty decent offer I suspect. At least I hope it makes some affected customers happy
If they do not wish to trade version 1 then I will simply offer version 2 at a reduced cost to them.
The reason version 2 will be more expensive is because I designed my own driver, my own emitter PCB and a new blank pill all from the ground up and specifically for this application, and this application only. Aside from low level parts (which all come from China or Japan pretty much) all assembly work will be done in Australia using Australian made PCBs and heat sinks, with American sourced springs and hand assembled by my brother and I. The new design dramatically reduces the amount of work we have to do to assemble a module but more importantly requires no physical modification to meet individual customer requirements. The spring system is solder-less and the whole unit requires no epoxying (but is still just as resistant to the elements as other epoxied designs). I've
seriously cut down on the potential problems to the point at which it's practically idiot proof - ie// Matt proof. We'll also be running a small trial period to test the driver as much as possible before I make them available for sale. I will build some prototypes and request a few CPF members test them for me. No idea who yet but people with a history of providing reviews (so efficiency testers, UI testers etc) will be asked. One or two members who purchased version 1 will be asked as well - most likely those mucked around most by the flickering.
Hardware design will be completed early next week (was supposed to be today but I had an unintended trip to the doctors) which will allow me to nail a price down. I am still a month or so off announcing anything though as there is some software work to be done to allow the thing to light up!
Thank you all for your patience.

EDIT: Just in case Nailbender reads this and thinks "what the hell Matt you said you didn't have a good source for springs!?" this is still the case. These American made and sourced springs are not suitable for use in traditional P60 drop-ins that the likes of Nailbender, Vihn and Oveready make. I designed the battery end of my drop-in around these springs, rather than selecting a spring that would suit my drop-in, so these will only work with my design. Nothing ground breaking, but certainly different and IMHO a big improvement. That's all I will say for now. Thanks!
