Well, I took a look! Nice, think our guy might have some tips to pick up from you. How much was a completed unit, then? Or how much would it be if you were making 500 of them? 

A UV LED is nice, IR remote is nice (though with 3 buttons?), colour sensor, all that... But that's more for a gadget you'd make and own yourself. People will tend to buy things to do those jobs separately. I'd stick to a product that does one thing, and costs less, if you're selling 500. Even though yep it is a cool toy! 

I never quoted a completed unit, but if I were to do so, I estimate it would be <<$50.  The BOM cost at 100 qty was $23 in parts from Newark, but that didn't include the LDC1000 inductive sensing chip.  I thought of doing another quick Kickstarter, but I have something much bigger going on right now and I feel like it would be a distraction.  

If I *were* to quote it, I would go to Moko Technology in China.  That's where I had my BooSTicks made and they were 1/3 the price of Seeed.

It's nice that ordinary people can have something done, like your Boostick, in a small enough run to be affordable, and I imagine make a small profit. In the past you'd have had to have thousands done, I'm sure, or find a factory with some spare production capacity. And they'd charge you for setup etc. I'm sure it'd have been way beyond the finances of an ordinary guy who had a useful idea for a  gadget.

It's nice that factories can solicit directly to inventors, and vice-versa. And that you can sell a product without needing a chain of shops to stock it for you, or else be stuck with mail-order. Viva L'Internet! Yet another society-changing thing from the last few years, world changing in my life as an adult.

Still, liked the Internet better back in the 1990s. In a parallel world, a beautiful utopia, Mark Zuckerberg was killed, quickly and painlessly of course, on his way to his first day of college...

Thanks!  That's very cool.  A bit overkill for what we are trying to do, though.  Our assembled cost is less than 1/3 of the Magicshifter since we don't include things like the UV LEDs.  I love their design,  though!

you are welcome, all the design files and software are open source and under e free license, so make sure to check that out.

especially the picture stabilization alorithm using an accelerometer is really worth a look.

the design is totally bloated with so many sensors that you wont believe it.

it can be used as an IR remote control, it has a colorpick sensor, an UV led, a super bright flash light led, a realtime clock and 12313123 other features that you dont need to make a blinky gadget. but it is an extraordinary cool toy.
