RedBubble sticker order
I recently (07/08/2021) ordered some stickers from a company called RedBubble.

The order arrived today (12/8/2021), much quicker than expected, which is great and just in time for the Debian releases too (given some of the stickers are Debian related. Well worth taking a look at their website.

Gaming on Linux – Open 3d engine
This was posted to Mastodon, so am sharing here to. Update on the Ppen 3d gaming engine.
Still moving alone quite quickly! The Open 3D Engine (O3DE) from the Open 3D Foundation (headed by The Linux Foundation) is a game engine donated by Amazon based upon Amazon Lumberyard.

Planck's Constant Module
One of the projects from the CLEAPSS website resources is to build a small module (circuit) to help determine Planck's Constant.
I have built this up,with a minor modification (for now at least)
- The circuit needed 5 LEDs Red, Orange, Yellow, Green and Blue. I have built this up and allowed space for a 5mm Orange LED as i don't at present have one. I do have the other colours, plus importantly the data for each The data information gives me the wavelength in nano meters (nm) for each of the colours.

This is the built up module. I am using a CR2032 to provide the power, I could not find a PCB mountable switch that I wanted for this. So i just soldered on 2x 2.54mm PCB headers and this can be bridged for the switch. Works fine.
The 1k potentiometer works fine along with the 1k resistor I think is there to provide that extra protection to the LED's.
The same image, from a different angle is below

I can't provide a link to the resource for copyright reasons. If you work in a school you will find this project in the Physics resources.
