Custom SkyRay King SRK Driver

Maybe put together DIY kits… I dunno there has got to be a way. Preferably in a way that gets you compensated for doing the the hard part.

This is the best driver topic ever. :slight_smile: I will be interested in two of these drivers definitely if you do begin building them to sell.
I will keep watch on this topic.

My $30 King died today, last week one of the leds quit and then today I tried using it briefly and the remaining two leds have only one mode, a new very weak moon mode. :_(

I used it probably 15 to 20 hours before it died, I was hoping it would last longer. I liked using it on low under the house fixing plumbing leaks. I guess I have a reason to mod it now.

I asked Fasttech how much for 5000 ’7135 chips? … haven’t heard back yet…

subscribing, and hoping

Still watching and hoping it goes well. :slight_smile:

Finally got a quote back on some large quantities of AMC7135 chips. Will probably build them up with 350 mA chips (2.8A/LED)… 380 mA ones cost twice as much. Adding a single 350 mA chip would bring the current to 3A/LED

This will probably be a stupid question, not sure if the pin arrangement is the same but could ATTINY85 be substituted with attiny13A ?

Good point on the cost savings. I will still be definitely interested in buying one or two of these if you build them with those modes you planned :slight_smile:

It uses the TINY85… code is around 6K long…

yes, and I have code/UI that I like very much burned into attiny13a (purchased and locked) …

Do you still plan on using your friends pick-and-place machine? It sounds sophisticated and flexible if it can place all those 7135’s at the necessary various angles. If youre able to do it, a vid of that baby in action while making these drivers would be cool to see.

I was thinking of using a commercial board house to assemble the boards.

Ron’s machine will be rather slow and may not be ready for a while. He is trying to do some fancy pants image recognition to align and place the parts. So far it’s looking pretty good…

If you go the commercial board house route, do you know about how much you would be selling them for?

:wink: i second the notion :wink:

This is sounding good. Of course this like… what- the choir preaching to the choir? How much and when?

Ditto!

I would LOVE to get a PCB from OSH Park and get the components and build my own...or pay some money for pre-built...I have a SRK and definitely are interested.

Tell ya what...trade you a pre-built lead acid battery desulfator for one of those (got mine from OSH Park as well)

OSH Park (Open Source Hardware) guy makes PERFECT PCB’s for dirt cheap…
