Years ago you had to either build your own signal generator or buy usually a quite expensive signal generator. Lately there has been a push for very cheap ($15-25) digital function generator kits available from China. I wrote about some interesting function generator devices few years ago, and here is a closer look to one →
Prediction articles: 2020: A consumer electronics forecast for the year(s) ahead AI Chips: What Will 2020 Bring? CEO Outlook: 2020 Vision: 5G, China and AI are prominent, but big changes are coming everywhere Top 10 Tech Failures From 2019 That Hint At 2020 Trends – Last year’s tech failures often turn into next year’s leading →
There is a quite new electrical safety standard you need to know: IEC 62368-1. If you are working with electronics design, you need to notify this new standard. IEC 62368 is an entirely new product safety concept: it isn’t a merger of existing standards, but it does cover the older standards IEC 60065 and IEC →
I have made earlier a post on electrical car charging cables and charging stations technology. This s a continuation posting related to it. This posting links to DIY projects related to electrical vehicle charging cables. Those cables are quite expensive, so some DIY persons have tried to make their own versions. Some even claims have →
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 →
Cheapest Linux-capable computers are very cheap – just few dollars. “These processors are nearly cheap enough to give away.” So this embedded developer got an idea of making a barebones Linux board in a business card form factor. We have seen electronic business cards before, with various fun features including emulating USB flash drives, blinkenlights, →
It is pretty easy to do soldering ….Apply some flux, Heat the surface and apply solder .But when it comes to soldering SMD components it requires a little bit of skill and some tools and accessories. Industries use re-flow ovens with temperature profile Control to mass produce circuit boards. If you don’t have re-flow oven, →
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 →
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 →
There has been questions like those on 2600 magazine Facebook group: How do you prevent your phone from being used as a bug so malicious individuals can spy on you? What’s the best way to temporarily block/disable the microphones in an iPhone. Does anyone know of a phone case with a built-in shutter? The idea →
