Electronics Design

Circuit board manufacturing

One of the key concepts in electronics is the printed circuit board (PCB). A printed circuit board (PCB) mechanically supports and electrically connects electrical or electronic components using conductive tracks. Simplest PCBs have only insulation board with copper traces on one side. More complicated PCB is sort of like a layer cake or lasagna- there

NE555 DIY organ electronics kit

To introduce  a kid to electronics I ordered  DIY NE555 Electronic Organ Teaching Kit kit from Banggood (cost around 3 Euros). They sell also many other similar kits, but this seemed to be good quality at decent price (around 3 Euro).  There was not much information on the product page other than product picture, circuit

Needling Your Projects: 3D Printed PCB Probing Jig

https://hackaday.com/2019/11/15/needling-your-projects-3d-printed-pcb-probing-jig-uses-accupuncture-needles/ Trying to probe a modern electronic circuit with tiny SMD components, without letting the magic smoke escape in the process, can be quite a challenge. [Giuseppe Finizia] solved this problem with a 3D printed PCB probing jigthat uses acupuncture needles. [Jonathon Oxer] from the YouTube channel SuperHouse did a very nice video on the

A Carbon Nanotube Microprocessor Mature Enough To Say Hello IEEE Spectrum – IEEE Spectrum

There has been for several years talking that nanotube transistors are coming to use and they can be better than traditional transistors made of silicon. I see this news as a major milestone. IEEE Spectrum writes: https://spectrum.ieee.org/nanoclast/semiconductors/processors/modern-microprocessor-built-using-carbon-nanotubes Engineers at MIT and Analog Devices have created the first fully-programmable 16-bit carbon nanotube microprocessor RV16X-NANO. It’s the
