We are heading into the final stretch of the conference. If you are deploying capital into hard-tech, structuring strategic grants, or building LEO constellations, let's talk about securing Africa's orbital access. #DeepTech #NSAC2026 @SpaceAgencyKE #VentureCapital #SpaceTech

What a beauty! 🚀🚀

I don’t really understand the maths it takes to send humans behind the Moon and bring them back safely. And the more I sit with that, the more it genuinely messes with my head even tho my love for physics and my knowledge of physics is astounding to a point Somebody had to work out a path where the Moon’s gravity is pulling you in, the Earth is pulling you back, and you’re moving just fast enough and not slow enough not to get trapped by either. They had to figure out the exact angle to come back into Earth’s atmosphere too. Too steep, you burn up. Too shallow, you bounce off and drift into space. And they had to get all of that right at the same time, for real people sitting in a small metal capsule about 400k kilometres away from home. Nothing in that system is standing still. The Moon is moving. The Earth is moving. Even the Sun is pulling on everything. And still, some people looked at all of that motion, all of that chaos, and turned it into numbers you can follow. Go here. Adjust here. Come back here. And unlike nepa light, it infact works. There’s also that moment in the journey where the crew passes behind the Moon. No contact with Earth. No signal. Just silence, with a massive rock blocking everything they’ve ever known. The only reason they can stay calm in that moment is because someone, somewhere, did the maths and proved they’ll come out the other side. I don’t know what it feels like to trust something that much. To put your life in an equation when you’re that far away from everything. But I do know this for sure, whatever that level of thinking is, whatever it takes to reach it, it might be one of the most extraordinary things human beings have ever done...

Only ogs remember these apps

First time using windows after switching fulltime to Linux. I'd still pick Windows 10 over @Windows 11

(5/5) We've developed a comprehensive Human Machine Interface (HMI) that serves as our dashboard. All sensors and actuators (including the robot arm) are monitored and controlled via this interface.

(4/5) We have customized an AICO 200L MIG Welding Machine enabling us to measure Wire Feed Speed (WFS), Voltage and Current. We've also integrated thermocouples to measure workpiece temperature: Crucial process parameters in WAAM.

(1/5) Wire Arc Additive Manufacturing in Kenya. Update #1 The first year entailed building the foundation - simulation tools, scripts, circuits, and workflows. In 2026, research & development accelerates! #MadeInKenya #robotics #WAAM #AdditiveManufacturing #SmartManufacturing

Printing metal made easy! 🖊️ Most metal 3D printing today relies on heat. Lasers or electron beams melt metal powder or wire, fuse it, and let it solidify again. That works, but it’s inefficient: a lot of energy is lost before it ever reaches the material, and even more is wasted as heat dissipates into the surroundings. This work explores a very different idea. Instead of melting metal, it uses high-frequency, low-amplitude mechanical vibrations to temporarily lower a metal’s yield stress and enhance atomic diffusion. Under these conditions, metal can be shaped and joined without full melting. By combining shaping and joining at the same time, the researchers introduce a new additive manufacturing process called Resonance-Assisted Deposition (RAD). Because it avoids melt–solidification, RAD is far more energy-efficient and enables things that are difficult or impossible with conventional methods. Pretty cool method!

‘The Thinking Game’ documentary has just passed 200M views on YouTube in just 4 weeks! 🤯Perfect holiday viewing if you’re interested in a behind-the-scenes look at how an AGI lab works, or what goes into making a Nobel Prize winning project like AlphaFold happen.🧬🚀

@b3npayd Way to go chief🎉

update: we just got payd :)

@iyoushetwt Started with Notepad on Windows, then Notepad++ (Major upgrade of my workflow at the time!) Current code editor: VS Code.

What was the first code editor you ever used? Mine was Sublime Text

While in campus, I once made an electronic setup to simulate blowing the candles for my girlfriend on her birthday 😎🤓. github.com/codewithlennyl… #romantictechie #arduino
