#72 Learning to MIG weld

While living on the farm I couldn’t help but notice the necessity of a welder. From fixing gates to fixing vehicles and setting up fences. Creating burglar guards and security gates. These are all musts especially in the dangerous rural areas in South Africa.

So I endeavored on my welding journey, looking for the best welder for a beginner. After months of research I decided on the MAC AFRIC 180 A IGBT (MIG & MMA) Industrial welding machine. It has (120A=100%, 150A=60%, 180A=35% ) duty cycles.

I purchased the machine from Adendorff

After setting up and practicing a few beads I got the hang of it, Just need to improve my bead and reduce splatter. More practice.

My first bead… quite a hot mess.
Second bead (on the other side) much better but still needs work…

Very happy with this option as a first timer welding steel.


#71 ESP32-CAM WiFi & Bluetooth Dev Board

The ESP32-CAM, is a fine product of Espressif, and features WiFi + Bluetooth with an onboard Camera and even a built-in flash for complete solutions to IoT, so you can give your IoT systems eyes to “see”, in addition to the many Sensors that allow them to “feel”.

The camera included with this development board is the OV2640 camera, which is surprisingly high quality for the low price that it’s typically offered for. However, the board also allows use with the OV7670 camera too, allowing you to use whichever camera best suits your project – with more than enough computing power to operate a range of different tasks, and multiple sleep modes for impressively versatile power consumption.

This product is comprised of two parts, one of which is the Development Board while the other is the OV2640 camera module. This allows you to utilise these separately, or as a single unit, giving you more freedom to take your projects in whatever direction they need to go.
