The Missing Piece for Project Success
From obsolete vehicle and marine parts to rare industrial components — we connect you with what others can’t find across South Africa.
In a follow up to our article on South Africa data centres, research shows we now have 60+ data centres. I explain where they are, why POPIA drove the boom, and how operators beat Johannesburg’s power and water crises.
AI data centre water usage is sparking backlash worldwide. I compare it to the 2016-2018 bitcoin mining outcry — with a Brackenfell, Cape Town case study.
Lithium Imports and Shipping Risks – Why South Africa’s Battery Supply Chain Still Has Big Gaps. South Africa has always been good at moving heavy industrial goods around the world. We built an entire logistics and distribution culture around it. Yet when it comes to something as fundamental as batteries — the very things that keep vehicles, factories, data centers and now homes running — the supply picture remains surprisingly fragile and this is not just a national problem!
CAD CAM software CNC 3D printing guide covering G-code theory, free and paid training, controllers, drivers, limit switches, spindle speeds and best filaments for makers and hobbyists.
Vinyl vs CD vs tape compared. Why vinyl and open-reel made a comeback, the loudness war’s effect on CD fatigue, and the best collector turntables and tape machines.
Coolant leaking into automatic transmission isn’t bad luck — it’s a 60-year-old design flaw. Why BMW, Volvo, Mercedes, Audi and Nissan gearboxes fail, and what it costs.
Lasers vs Masers vs HPM Weapons – Confused? Clear explanation of how they work, the real difference between them, and why HPM and laser systems are changing modern warfare — written for students, electronics fans and gamers.
Single Sideband Transmitters & Receivers – Pure Innovation Radio communication has always intrigued me, as with the enthusiasts of the international Amateur Radio League. Having
Discover the key differences between subtractive vs additive manufacturing. In-depth comparison of CNC machining and 3D printing for hobbyists, makers, and small businesses in South Africa. Real DIY insights, kits, controllers, and practical advice.
Discover FinFET and Gate-All-Around Transistors technology — the advanced 3D architectures powering modern semiconductors. Learn how FinFETs extended Moore’s Law and why GAA (nanosheet) transistors are now taking over at 3nm and below, delivering superior efficiency, performance, and transistor density for AI, smartphones, and high-performance computing.
Discover the fascinating world of Thermionic Valves (vacuum tubes) in Part 3 of our active components series. From the Edison Effect and Fleming’s diode to the triode, pentode, magnetron, and iconic CRTs like Sony Trinitron, explore the history, operation, biasing, and enduring appeal of these glowing devices in guitar amplifiers and classic electronics. Learn why tubes remain preferred by audiophiles and musicians despite modern semiconductors.
Discover the world of power switching semiconductors: from thyristors and TRIACs that powered my first disco sound-to-light system, to modern IGBTs, GTOs, SIDACs, and wide-bandgap (SiC/GaN) devices. Part 2 explores their applications in industrial motor drives, renewable energy inverters, EVs, and switchgear. Learn advantages, disadvantages, timelines, popular components, and critical safety warnings when working with 230V mains power. Essential reading for electronics enthusiasts and professionals.
