3D Scanning with Autodesk 123D Catch

Gareth's picture

This 3D scanning software took me a long time to find out....

I just bumped into this Autocad 123D Catch app which impressed the hell out of me.

The object you see is a project I made a few years back using Polymorph plactic (thats how you made 3D plastic stuff then)

Test rig :- 4 IRs dangling from space

Its basically a Nintendo WiiMote camera which is able to track 4 infra red leds/laser giving XY coordinates and also the size of the blob seen.


Weather prediction - using wunderground.com with a WiFi enabled ESP8266

Gareth's picture

I have been experimenting with OLED displays, json strings and Web Weather sites.

I plumped for the wunderground.com weather site.

You have to signup for a free account which allows you to poll the site 500 times a day (hum...so a scan every 2.5 minutes...not bad). They then supply you with a YOUR_KEY (see below).

I am using an ESP8266 as the wifi link to wunderground site.
