<div>Sensebridge Cyborg Meeting April 5th, 2009<br />
<br />
==Introductions==<br />
<br />
* Rachel - doing "eyes on back of the back" vibro-vest<br />
* Rendy - likes buildings things out of electronics. From the meetup list - and Rachel has been telling him about Noisebridge. He made the microphone-armature breathalyzer. Can we make an inverse volume control for karaoke mics?<br />
* Matt - interested in anklet project<br />
* Skory - linguistics, bought an electronics book.<br />
* Eric - anklet, mechanical and electrical engineering<br />
* Corey - Denise invited him. Wearable computer boots which flash, which sense when you tap/kick something. Communicate with other similar boots. Click your heels three times and they turn ruby. Works with Swarm, which is doing something similar with hexagon thingies. <br />
* Mikolaj - anklet as well. Wants general spacial awareness like Rachel's vest, context sensitive - longer distances when you are on your motorbike (motorbike has radar rangers), etc. $5 modules for cruise-control distancing (radar) available now (message to list about this). (left early)<br />
* Michael Kan - touted Design Engineering Thursdays again<br />
* Denise - making [https://lilpeepmerch.net/product-category/shoes/ converse shoes]!<br />
<br />
==Boots Discussion==<br />
<br />
Denise is going to do boots.<br />
<br />
Can we put a pico projector in them?<br />

==Discussion of Ultra-sonic Rangers==<br />
<br />
Kinda crappy at distances larger than 3 feet<br />
<br />
Want three directions - the three lanes behind you (left, center, right). <br />
<br />
Phased array may be possible & better, but would probably require a fixed (not fabric) armature<br />
<br />
LIDAR - could we rig up our own to avoid the expense of commercial systems? Story about 3D scanning using laser, wine glass and turntable with matlab script to do the math. <br />
<br />
<br />
==Order Distributions==<br />
<br />
RBBBs, Batteries, and Shift Registers are all in.<br />
<br />
Mikolaj paid Skory & Eric for RBBBs and Batteries<br />
<br />
Rachel paid Eric for Batteries<br />
<br />
==Show & Tell==<br />
<br />
Rachel:<br />
Has lamont shift register to drive motor.<br />
Has functioning circuit using ultra-sonic ranger ("sensor module").<br />
The Maxbotics works better than the Parallax Ping))), and it's half the size and easier to work with. They can also be daisy chained. Range is about 3 feet reliably, Ping))) was about 2 feet. They also sell different focussed version - more focus gives more distance, but less angle. Difference may be in code only. <br />
So sensing is a large problem - she needs 10 feet!<br />
<br />
Eric & Skory:<br />
New armature, with pockets & velcro & ribbon cable.<br />
New small circuit using RBBB and Shift Register.<br />
Analog compass which turns on motors? Ten pins sticking out in a circle. <br />

Super promising for an entirely analog compass vibro-anklet, which would be much simpler and cheaper than current Ardiuno one, but of course less flexible.<br />
