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)

ESP8266 capturing 4 Infra Red dots/markers using WiiMote camera

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 with a WiFi enabled ESP8266

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

I plumped for the weather site.

You have to signup for a free account which allows you to poll the site 500 times a day ( 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.

ESP8266 meets the force....
Using the code posted here
for the Arduino, with some minor changes it ports easily over to the ESP8266 WIFI ........

"Blynk"_ing your ESP8266 Wifi - Servo Example

What is "Blynk" .... It is a Smart Phone APP that uses either Android or iOS to IoT your projects for remote control.

High Tech. or Low Tech .... Principles stay the same :-)

BlueSun ESP8266 WiFi 'o' Sonar

Gareth's picture

Continuing the theme with my ESP8266 WiFi "Wonder" chips.

First experiment in making a sonar scanner for remotely displaying depth/distance mapping.

The MaxSonar EZ0 is mounted via a 3D printed mount directly to a simple stepper motor.

The Stepper motor is controlled directly from the ESP8266 output pins.
