OLED – 128×32 SSD1306 This OLED uses the SSD1306 driver, it is 0.91" in size, and has 128x32 pixels.
M5Cam
I am going to use the M5Cam as a surveilance camera for wildlife, it is a very simple setup, connect the M5Cam to a 5V battery source through the grove interface, and design an enclosure for 3D printing.
M5Cam – ESP32+OV2640 RPi UPSPack Standard RPi UPSPack Stadard case
The case above holds the RPi UPSPack Standard, the cut outs are for USB ports, and the hole in middle will have the…

3D printing-Making an enclosure
3D printing-Making an enclosure
Making your own enclosure for your electronic project, is a very rewarding way to showcase your creation.
To help you do this I have included my own experiences of making enclosures, over a hundred so far, and will share my procedure below.
Design
When designing my electronic project I make sure that I keep the limits of 3D printed parts in mind, and also exploit all possible…

ESP32-CAM
ESP32-CAM as it’s name implies,  is a low cost development board with WiFi camera.
It allows creating IP camera projects for video streaming with different resolutions.Â
ESP32-CAM has build in PCB antenna. ESP32-CAM-UFL is the same board but with U. FL connector ESP module – an external antenna can be connected.
I will be using an external antenna, as streaming video is very poor using…

Badger paint Mixer Holder
Badger paint Mixer Holder
I just designed a holder for my Badger paint mixer, it is an essential tool for mixing my paints for airbrushing.
If you like the 3D printed holder and want to print your own, or maybe even customize it, the file will be available to download soon.

New Graphics..
We just designed some new graphics using Inkscape and Gimp2…
Meet our new robot mascot above, we will use him in various poses around the site, where appropriate of course.
The next graphic is a MakeBlock robot we have been playing with lately, more to come soon!

Sense Hat - RPI Zero
Sense Hat – RPI Zero
We are using a Sense Hat ( Astro PI ) connected to a Raspberry Pi Zero to collect environmental variables, we will be collecting temperature, pressure, and humidity readings using the on-board sensors.
We will be using the readings to compare against those collected from a DHT22 connected to a LinkNode D1.
We will upload the readings to ThingSpeak.com, and display the two sets of readings…

ThingSpeak Experiences:1
Thanks to ThingSpeak for allowing us to upload data and get real time graphs and Matlab analysis.
So far we have managed to upload temperature, humidity, and light levels to a ThingSpeak channel ( 212605 ).

Arduino + ThingSpeak
We recently had a weather report warning of a very cold snap with the likelihood of snow.
We were told that temperatures could drop to below -10 Centigrade.
This is a good opportunity for us to use an Arduino combined with a DHT22 temperature and humidity sensor, and light sensor, to record data during this weather event.
So let us decide what we will use…
