These units are not fully water proof, but if you break them its okay. should I have different wrist sizes? is this more hassle then they are worth? do they properly activate? Would a jacket with indicators fit in be more effective?
Also when the arms are completely dropped and resting by your side, because of the analogue method chosen to activate the lights these units will flash. Is this going to be a serious issue?
If I were to choose a digital method of light activation, the cost would be nearer £30 for a set of wrist bands, would you still buy them?
My logic was, make them as cheap as possible
Waterproof is essential for final product, it's a very common and annoying failure of lights.
If they are likely to flash when not in use, why not just have them constant, with a simple on / off switch? Surely a tiny LED will only use a small amount of power, and this would be simpler / cheaper?
Is a switch what you mean by "digital method"? Surprised it would cost so much more.
As I said, my mate bought two tiny lights with elastic loops which strap round his hands. They cost about £5.

okay so some answers for you guys. It is made using 4 mercury sensors, that require 85 degree angle or more. I believe when I made it you had to hold it for something like 0.8 seconds. This I found worked really well. This is pretty much an analogue solution, in an ideal world you would choose a digital accelerometer and gyroscope.
The second image was the first one I ever made so hence the size, all the units I will hand out are like the first image. Again when I originally tested them the 2 LED's were adequate, if this were to go production, these would be much brighter.
These units are not fully water proof, but if you break them its okay. I do not mind, they are testers. If this was ever to go to production, I need to know things like, should I have different wrist sizes? is this more hassle then they are worth? do they properly activate? Would a jacket with indicators fit in be more effective? also guys remember that all of these units have been hand made.
Also when the arms are completely dropped and resting by your side, because of the analogue method chosen to activate the lights these units will flash. Is this going to be a serious issue?
If I were to choose a digital method of light activation, the cost would be nearer £30 for a set of wrist bands, would you still buy them?
My logic was, make them as cheap as possible so everyone anyone can use them and make it so they can be used in summer and winter and it must not tie you down to a particular style of clothing.
