A rolling test stand is a really nice tool to have. But I was not using mine because it was not installed permanently. In this video, I will be modifying and installing it on my workbench ready to use.

I have the STL files for the blocks available on my GitHub if you want to make one for yourself.
All that you need is some 3mm and 6mm linear rods. Plus some M3x10 Hex bolts. The trolleys can be found on AliExpress. (search for: Track Roller Test Stand)

• In this video, I'm converting a Märklin BR 128 to new LED lights and an ESU Lokpilot 5 using PCBs designed in Eagle CAD.

This will enable high beams and shunting light which the standard Märklin decoders do not have.

In this video, I'll be modding a Seiko SKX007K2 Divers watch.
The movement will be upgraded to a Hattori NH36A hand winding and hacking movement. The Dial will be swapped to a white SNK369 Racer Dial and the Seiko bracelet is swapped for a Miltat Super Oyster bracelet.

In this video, we'll be delidding soldered Xeon CPU's for use in a Mac Pro 4.1

The delidded CPU's are actually the ones used to edit and render this video on.

I conceder the delidding method used in this video the safest one compared to others seen on YouTube.

In this video, we will use the ESP32 with integrated OLED as an internet connected Bluetooth Low Energy Client to a Heart Rate Monitor.

We will display the Heart Rate on the OLED Display and also send it to an MQTT topic to switch a lamp on and off.

Big thanks to Andreas Spiess for his YouTube Videos.
And also massive thanks to Charlize Theron for raising my heart rate again and again.

In this video, we will use the an ESP32 with OLED display to connect to the WiFi module in a Omniksol Solar PV Inverter.

The data from the inverter is stored in a struct array and send out to MQTT and displayed on the OLED display.

The code will even work if you don't have an OLED display. It will output the data using the serial port.
