Hello World!

Oh, this was Blogger... Oh well, nevermind. We'll stop coding for a moment to give you guys a heads up of where we are now.

Since last post (was it 8 days ago all ready?? Sorry for that, we have been making progress, while problems have kept us busy) we have made new IR-beacons with our new power led's! Also now we have case's for the IR-beacon's (still need's some adjustment's), made a solution for attaching the cameras to truss with Superclamp and some coding. I'll add some photos to explain better.

First some messages from our Gateway running on
Raspberry Pi 3.

After calibration last week we started to receive some coordinates of the beacon.
Some tidying up need's to be done.

We got our new LED's and some resistors \o/

Tatu soldering our new 3W power IR-led to heat sink.

We also added small RGB led to our beacon to tell it's status.

Close up (almost) of RGB led and resistors on breadboard.

Part of ping pong ball on top of RGB led. All colors on.

As we got beacon working, we started to do a case for it's
brain. Old tape case needed just a bit of cutting, sanding and
drilling to do the job.

Power led with heat sink attached to piece of plastic. That
should work as a base for our beacon. Part of a ping pong ball
will be attached on top of the base.

Trying to get everything in to the case. The fit pretty nicely.
In this (case_v1.) power switch is on side, witch will be
changed in v2 to bottom.

Case is ready now to be used. It will be transparent for now,
maybe in the future we'll use gaff or something to cover it.

When I was working on case_v2, I wanted to have beltclip on it.
I took an old coat hanger made from steel wire and cut a piece of it.
It had to be reshaped, so I took some alternative tools as we had no hammer
in use.

Creating new calibration grid. Took couple of hours from one man to do.

New calibration grid is ready for use. Now we'll have more accurate calibration.

Tatu doing calibration. Calibration is done by placing
beacon on a know position, and sending it's coordinates to
gateway (which act's as a server) After that gateway make's
calculation's from 2D coordinates coming from cameras
and is able to display 3D coordinates.

Making Max Msp patch and googling solutions for problem's. After a while
googling and one support call we got Max to send position to GMA2 via Telnet.
Not ideal, but we got it to work. More on that later ;)

I'll keep you guys posted!
