Put me down for 100pcs at the moment :slight_smile:

I can’t use a hundred, but I need about 25 right now. But I’d do more (maybe double that) if I had to to get the numbers up for this to work. I’d MUCH prefer them assembled and would take a “short-order” (3-5 for immediate field/beta testing) sooner than later!

That’s very doable. I bought enough to make 10. Anybody who wants some for beta testing let me know. USA shipping is easy, Funtastic, let me know what is the best method for NZ if you are interested as well.

I’m interested in a few of each size, assembled please.

Thanks

4 of each assembled please

JaredM…

I see you are from USA and Quadrupel is from Europe…

I am from Europe and I know that shipping from USA to EU is PITA. Expensive plus additional 25% of tax on whole order.

So your idea to include Quadrupel in this story would be great for EU costumers.

I need to try sample order to see weather it will work ok for my rig.

So far from what I can see it looks fairly simple with enough room for soldering components. :+1:

Are these compatible with 2S lights?

Thanks

A 2S spec can be made. Currently I have ordered a 6.3V capacitor. 10V would be required for 2S. Easy enough change to make. Mosfet is okay with 2S

Whatever is cheapest haha, I’m not familiar with what’s available over there. Needs to be tracked though.

Zappaman mentioned he’ll pot these, they don’t need it do they? I’ve never had an issue with any Convoy driver failing due to recoil

To clarify… I’d only pot the FET in the tail (mostly to waterproof it) using JaredM’s punch through the silicon tail method. As there will be no battery (that may need servicing after a few years), I can’t see why I wouldn’t “pot” the thing (with silicon most likely, but ideas???)

Silicone is most appropriate if you go that route. I think this method along with a spacer ring(s) the same thickness as the switches they replace makes this a near universal fit.

This board also provides reverse polarity protection intrinsically.

Hoping parts show up next week.

Just pulled out my Sofirn pressure switch and it also requires too much pressure on the pad, no different to Convoy’s. I guess we can all go our own route with what we buy since this thread is just for the boards.

Put me down for 100 pcs. Good overall price could be achieved if we have finished switch assembled in China, with this setup the final price of the product will get 5x times the regular Convoy switch. If Simon manages to source locally the wire/button and assemle the switch, I guess we can finish ~ 2x price of current switch, which will bring totally different numbers of orders.

Yes, but if it’s assembled in China the guys who designed it wouldn’t get paid

From what I understand from JaredM… this PCB can easily be soldered by most who own an iron. So I’m now ordering mine in “kits” Vs. assembled since there are no specially soldering tools needed. I ALSO understand there is a mod needed on the driver, wondering how that might work (*as we use these for different lights)? Might need tech support there ;)>

A bleeder resistor is needed on the driver. It’s the same concept as using a lighted tail switch.

If someone else is interested in producing these in another place they can go for it. I’m going to make these in the USA, either all myself or with domestic manufacturing. The price is in line with what Lexel used to sell his boards without the need for a button cell.

I’m waiting on Oshpark to deliver these pcbs. Hoping to finalize this by the 24th of May and ship by June 4.

I would like (10) 20mm assembled… please…

I am still in for 100 pcs 17 mm assembled. I do not want to produce anywhere, just shared why my forecast is so low.

This is a game changer to me except if it is not piece of cake to solder lets say from spring side of the driver? I would have to see few pics to visualize that modification…
