Building a #Stirling #Engine #Bike.

A Stirling Engine is a heat engine, powered by the expansion and contraction of a working fluid [such as air] which is heated and cooled in a cycle. In the video [Tom Stanton] begins by demonstrating the Stirling Engine with some model engines and explains the role of the displacer piston. His target power output for his bike engine is 150 watts [about 0.2 horsepower]….

Successful high power test of the glider's electric motor with the spinner and propeller installed.

I had it at full power: 4600 RPM and 150 amps at 115 volts DC. I conducted this test three times. No problems with vibrations, excessive temperature of the motor or any other components, or rapid draining of the batteries.

This is a major milestone for the electric motor system.

Hey! I've been creating a #game #engine #framework in #vala

Its ECS based, and its called Veggies (eat your veggies!). 🥦

My reasoning for this framework is to have a game framework alternative to #csharp. I'm not liking the encroachment #microsoft has over #gamedev and #indiedev

The video is the well known bunny mark demo. Renders up to 16000 bunnies before being under 30 fps. Still needs a lot of optimization.

I'm taking ideas from frameworks like #pygame, #pine, #FNA and #excaliburjs

Because of AI slop and confusion caused by (often well-meaning) Americans on international online spaces, I was unsure if the engine on my #GolfGTI had just direct or multi point #fuelinjection

Managed to snag an official VW workshop manual and checked with my own eyes, was pleased to see the CHHA engine in my car does indeed have the extra fuel rail and injectors in the intake manifold (this is good, as #petrol sprays over the back of the intake valves and keeps then cleaner, without it they are prone to coke up and require walnut blasting)

I do not know why Americans only get engines with direct injection (into the combustion chamber), whether this is simply cost cutting by #Volkswagen of #America or some other reason..

Vello, github.com/linebender/vello.

Vello is a 2D graphics rendering engine written in Rust, with a focus on GPU compute. It can draw large 2D scenes with interactive or near-interactive performance, using `wgpu` for GPU access.

The more I learn about Vello, the more I'm fascinated by the number of state-of-the-art techniques that are used. It's so rich.

The #effect of #AI on #search #engine #traffic from #tech #guru Shelly Palmer. shellypalmer.com/2025/06/seo-t

Shelly Palmer · SEO to AEO: The Transition BeginsThe era of ten blue links is ending. Depending on the industry, search traffic is down 30-45%. It will never return to its former dominance. You could say, "Search has lost its job to AI." But this is just an interim state. Yes, we are at the beginning of the transition from search engines to answer engines. But answer engines are not the end state. Sooner than later we will be marketing to (and transacting with) bots. Until that time, we have some work to do. Let's explore some strategies and tactics we can use during the transition from search engine optimization (SEO) to answer engine optimization (AEO).

A few years before someone else jumps on the back of it, completes the project, and makes millions.
I love being British, but our inability to fund innovative projects is a major failing. I’m sure Frank Whittle, John Harrison and Christopher Cockerell (among many others) would agree.
