The Long Boring Bit:

We are Env Open Technologies. A group dedicated to affordable products that give you the right to modify and repair the device as you please, why pay for something you cant fix on your own? This project is being developed by two people. Argo, our head design engineer (+ support technician) and EnvIr0n (Psuedonymn). The lead software engineer for this project. 

Extensive research has been put into ensuting we are being cost effective while still staying high quality. The device uses an ATMEGA328 as its main processor, which has a low power consumption with high power combined with a cheap price per unit. Furthermore, 5 revisions of the schematics have been drafted to ensure the best performance and proper connections between components, aswell as 3 circuit board drafts. We have now settled on ENV-005A.rev3 as our final circuit board.

The money is going to manufacturing the final product and sourcing some extra parts for even more rigorous testing. Some (but nowhere near all) expenses are:
 - Circuit board manufacturing
- Component costs
- One-off manufacturing purchases, such as precision soldering iron tips, solder flux-gel, etc

A sucessful campaign will mean the product will finally get to the final phase of production after months of work.

This means alot, as this will be the first proper, public project made by Env Open Technologies, who otherwise has mainly done contracting and personal projects. This project idea was submitted by a local Logan Park Highschool student, we would love to send him one as a thanks for the idea, but we need your help funding this venture.

Ok, enough chatter, what even is it?

The P.E.A is a small device which will send an alert to your emergency contacts when pressed for 3 seconds. It acheives this through connecting via bluetooth to your phone, and using a lightweight sister app, will send an SMS with your location and a call for help to your set contacts. Yeah, that simple, and that's how it should be for the users, people don't want a long process, all the tech stuff is left to us, simply chuck some button batteries in it, put it in pairing mode, and feel safe knowing you have a discreet, silent way to call for help. Why bother with all the complex setup, use something simple, use a P.E.A.
