Oshpark Projects

Welcome tterev3…there are a BUNCH of absolute geniuses and artists here (I’m just the cheerleader :smiley: ), I stumbled across your build and video’s and about tripped on myself trying to find someone to invite you here to enter into the fray…with your expertise added to the pool…there is NOTHING you guys can’t whip up! I’m 100% positive on that!

tterev3, I just watched the videos- Very cool. Do you sell or have you considered selling some of your drivers?

I’d recommend going with v2. V1 has a flicker issue that can be solved, but it requires cutting a trace so small I needed to do it with a microscope. If you would much rather the single board solution, I could send you one of my v1 boards that I’ve fixed—I’m not really using them since I got v2 running. I’d let it go just for the cost of the components. Again v2 is a much better option though

I’ve thought about selling but I think the cost may keep most people away—there’s a lot of pricey components on the multicolor boards. If there’s interest I would certainly consider it though

How pricey are we talking?

I would estimate around $20 for a parts kit and maybe in the $40 range assembled

I’ll pm you to not tie up the thread. Thanks.

The name here might be budget light forum but quite a few members wlill drop a good bit of money into a flashlight.

The vias are open, I can see daylight through them, but there needs to be some kind of sealant between the PCB & body anyway so that's really not a big deal. They're a little thicker than the originals but that's a good thing - the switch bezel will clamp the PCB tightly, compared to the stock parts where the PCB floats around even when it's all screwed together tight.

Just got my 3x 7135-based SRK boards in today. They’re very nice. Not only do the purple and gold boards look great, they feel like they’re well made. I have my parts on order (though I may be waiting a little while for my 7135 chips from FastTech)

Overall, very pleased w/ OshPark (and shout outs to the board designers too).

I’ll post the links in the op if I have wifi in the next few days. Do you have parts lists for these and are you going to provide firmware or sell flashed mcu’s?

That’s a pretty amazing bit of programming in that video.

I’ll put together a parts list today or tomorrow and post it. It looks like most of you are set up to program Atmel parts, so it’s probably easier for me to provide programmed PICs, but if anybody wants to build one and has a PIC programmer I can provide the source

Welcome to the forum tterev3. You come here with substantial and unique knowledge acquired outside this forum. That is great because much of what has been accomplished here has been built "in-house". Thanks to hard work of former and current BLF'ers. I'm not one of them. I'm just a follower.

I have a humble request and totally understand if you don't have the time or interest to oblige. It would be awesome if you could create a thread giving a high level how to on PIC programming. Doesn't need to be step by step. Just equipment and software needed. I've attempted to research it a couple times, but have not been successful in finding much info on the subject.

No it's not. I designed it as a simple back up for something else I was making but I don't have any intention to actually use it. Figured I'd share it for anyone who wants it. Basically a 2 cell driver set up so you don't have to stack parts. 20mm in size so a bit limiting.

I'm no expert (hell I can't be bothered even compiling my own code half the time!) but I experimented with PIC programming when I bought a few of PilotPTKs 3xXML modules last year. From my experience, PIC programming (when taking into account the cost of equipment, ease of use of software, and component choices available) is a hell of a lot more troublesome and expensive than the ATMEL programming we generally do around these parts. I'm not sure what the advantages of PIC is over AVR, but I'll take AVR anyday. Again, that's just based on my LIMITED experience!

tterev3....Welcome! I actually emailed you through your site, never got a response but now I see that blogspot never actually informed me that you did respond. Email incoming :)

Thanks for you input Mattaus. Was hoping that wouldn't be the case as I have so many darn PIC based drivers.

Don't let me put you off it. A thread like you suggested might be helpful. If it's written by someone who knows their stuff it could show how little I really do know ;)

That being said I had to pay $40+ for my PIC programmer whereas my AVR programmer was about $2. The AVR programmer also clips straight onto the IC, where as the PIC needed break out pads and a home made adapter. Depends on what PIC package you choose of course. The PIC software was also not that great but I really can't compare it to AVR studio as I've barely used that either.

Run 3x layers of clear finger nail polish over em…that’s what I do when I want to weatherproof conformal coat PCB’s…that or run some clear RTV silicon over it and let it self level…but the bubbles…uggh

I just realised I never provided a Version 2.0 FET SRK driver. Did people still want it? It's done, it just hasn't been uploaded. It includes a few minor layout changes as the addition of the resistors on the FET gate.

But a large pepperoni pizza sure sounds good…

Before last night’s little coat pocket liner burn through, I had ordered an UCLp lens for the M6. It came today. I put it in and it looks awesome on there, anybody think the M6 will melt it?

Go for it…

Does it need the resistors on the FET gate?
