Exclamation Last Call for help

I'm looking for help everyone. As some of you know I started the delta RGB laser last year, and was unfortunately scammed out of a driver and a lot of money. I'm looking to pick this project back up and get it done.

I need a driver designed for it, and I will pay for the designs and your time. Since rgb lasers are becoming more popular I don't see any reason we can't open source or sell the driver.

Design requirements include adjustable current (from 200mA to 3A) and integrated adjustable pwm, two adjustable 3-5v outputs. a monitor and driver for a Peltier unit. A voltage in monitor, and a high temperature indicator.

Since this board includes so many options I'm sure I don't see a problem with other people being interested in purchasing a board, if it went into production.

I don't really have the time to learn and design this on my own. So I need this done for me. If I can't find anyone to do this, I will be selling the box of components I do have. You can check out my post to see what I have.

0 and 78 views. That's actually a record.

Would anyone be interested in purchasing a driver then? With three adjustable out puts, pwm capable, a Peltier driver, two adjustable 3-10v outputs, and input from a thermistor all on a 50mm board?

I found someone, but it'll be expensive to produce. So, who might be interested in said driver, and what price point would you buy it at?

It sounds like you just want to be the ideas man, but not do any of the engineering work. That's fine, but you really ought to offer a greater incentive than "oh, we could open source it or sell it" -- i.e. a financial incentive up front that covers the development costs.

That means numbers. People will not even start bidding unless you're in a ball-park range that it is even worth bothering.

Nobody has messaged me or replied offering to design it. I would do the work if I understood EE better.

Flaminpyro pointed me too drivers. But I can't design anything. I spent 20 hours on Eagle a year ago and I literally got nothing done.

I'm asking now, who would buy a Driver like this, and how much would you pay for it. I'm looking to see how many could be sold. What people, in their opinion, would pay for this.
