Project: FlashNade

One more gadget in our inventory.

It started out like this.
- - -

Then I found some high powered LEDs
20w to be exact :astonished:
cgi.ebay.com/ws/eBayISAPI.dll?Vi … 0181334382
Only had 2 so one side is 3x 3w.

The 20w are running at 3.5w.
You will want to turn away at less than 5m
At full power it will leave a dot in your vision for some time.
Once the smaller lipo cells arrive it will be 1/3 the current size.

Any sound component would just be an indicator as nothing would be loud enough to do it justice in that size.

Push button.
Starts flashing in 1.5secs
Flashes for 3 secs
After 5 mins flashes once every 30 secs to remind anyone nearby to collect and turn off.

What sort of cost would be involved in putting one of these together?

R

Aiming for a target price of $80

Key will be finding the right priced LEDs.

This seems really pretty reasonable.

R

Got around to making a revised version.

New modes
Constant on (1% brightness), for ambient lighting
Pulsing, for beacon

I was going to use ali but only had 2mm, not the easiest to work with.
So grab some lexan that was lying around.
