One I missed: OnSemi NCV68261 ideal diode and high-side switch - And, being partial to a nice ideal diode, I thought I would take a look. It is a neat chip, called NCV68261 and measuring 2 x 2mm... #EngineerInWonderland https://t.co/rqFftY8hpj
Current source rectifier confusion - “Reverse applied voltages of up to 20V will draw only a few dozen microamperes of current, allowing the devices to act as both a rectifier and current source in AC applications.” #EngineerInWonderland https://t.co/fOuhAAWlBa
Community-sourced desktop #CNC milling machine product - It is the Millenium Machines project which: “started life out as a mod for the #OpenBuilds mini mill, but has continued to grow into the ecosystem of machines and tooling...” #EngineerInWonderland

Ebay ‘collect in person’ – something you should know - Much stress later, miles from home, and having signed in to ebay and email accounts to a stranger’s computer, I found said QR code. #EngineerInWonderland https://t.co/19G6fRVaWI
App note on half-bridge emc tells you more than just that - Well worth a look as it is an easy read for such a technical subject. Hats off to whoever wrote AN90011 #EngineerInWonderland https://t.co/dBBnc19DSx
Pcb drills at Lidl! At least, my local one. They are branded ‘Parkside’ (a lidl own-brand) and are in packs of 10 assorted sizes, for £4.99 per pack. #EngineerInWonderland https://t.co/LF8n8WpMbh
A quick lens holder for Gaggione’s LLC15E and Cree’s XP-P - @DesignSparkRS Mechanical used, and I knocked some holes in the side of the model to speed printing – done in silver PLA from #Prusa #EngineerInWonderland https://t.co/pyDNZlwKWk
First rotating led lamp in a US lighthouse - “This upgrade is the Coast Guard’s first led-based rotating beacon for an active aid to navigation and will provide a permanent, cost-effective and energy-efficient solution” #EngineerInWonderland https://t.co/mQ4U3agz22
An interesting dc-dc topology: synchronised boost-buck - Slobodan Ćuk invented the Cuk converter – hence the capital ‘C’, which should probably be ‘Ć’, but that is not so easy on this computer – sorry Professor Ćuk. #EngineerInWonderland https://t.co/189ZEt0V2D
Switched tank converter? According to Google and the University of Udine, switched tank is a way to convert power largely using capacitors, resonating them with small inductors – that might even be well-controlled stray inductance #EngineerInWonderland https://t.co/MlUdVLTcIh
Locked down project – servicing loudspeakers - The caps come with a note that they have been measured on a bridge at the correct frequency, and they might seem the wrong value if measured on a multimeter as the frequency is not right. #EngineerInWonderland https://t.co/wyr7vUbQl3
Covid-19 3d printable mask approved – Designed at the Czech Technical University by its Institute of Informatics, Robotics and Cybernetics (CIIRC CTU), it's called ‘CIIRC RP95-3D’ and has to be printed on a ‘multijet fusion’ printer #EngineerInWonderland https://t.co/vswrF1eG0L
Open ventilator project – 3d printed emergency ventilator for covid-19 - The aim to to have something that can be made simply in many places around the world – to be used only when not enough ‘proper’ medical ventilators are available #EngineerInWonderland https://t.co/idC66rVHV8
#EngineerInWonderland: Some people say there aren't role models for young girls in engineering - technology editor Steve Bush says different!
His latest blog post contains a fantastic list of recommendations for female engineering content creators: https://t.co/CdsTWxB4xd
Great phase-locked loop motor control app note - And to someone who is in love with phase-locked loops (4046s to be precise), the only respectable way to stabilise such a thing is using one. #EngineerInWonderland https://t.co/bfvJdrUkCv
3d printing: the problem with cheap ‘dual-drive’ extruders? - The ‘hot-end’ which melts printing filament and delivers this to the thing being created #EngineerInWonderland https://t.co/ZTD5AdwOIb
#EngineerInWonderland: In his latest blog, technology editor Steve Bush recounts his experiments to find a simple way to charge a small Li-ion cell: https://t.co/zdn0q61KpK
Printing a case for Raspberry Pi 4 - I was going to chase it around the desk uncovered, and then I though I would design one and 3d print it
