    I figured there had to be something like this. A little easy-crimp connector that hooks wires to LED strips without any solder. Also have them for 4 wire strips and even butt splicing one strip to another. Also a version with screws if you're a barbarian. ';^) #electronics

    I'm really hoping for Fediverse help here.I have a 14 year old niece. She's incredibly smart and extremely motivated when it comes to engineering things.I want to get her some electronics stuff, like an Arduino kit, but maybe something with wearables, etc. to make it more relevant to her than just a breadboard.She'll also need some books on electronics, since she doesn't have the background in that.Sadly, some limitations:- I can't help her. Her mother won't let my wife or I talk to her. This gift itself will have to be given through a third party.- She has a learning disability around reading- likely dyslexia, and so we need material that's easy to read- Her English is not amazing, especially because of the learning disability.So I'm looking for a kit with a ton of instructional material. Programming, electronics, breadboard, the whole kit and kaboodle.If you have ideas, please share, and boost!#Maker #Arduino #Wearables #FediHelp #Electronics

    Heart Rate Monitoring via WiFi.Before you decide to click away, thinking we’re talking about some heart rate monitor that connects to a display using WiFi, wait! Pulse-Fi is a system that monitors heart rate using the WiFi signal itself as a measuring device. No sensor, no wires, and it works on people up to ten feet [30 meter] away.https://news.ucsc.edu/2025/09/pulse-fi-wifi-heart-rate/#PulseFi #wifi #heartrate #monitoring #diy #esp32 #engineering #media #tech #maker #news

    @mdione I mean, you don't buy your tools based on the availability of free software firmware to flash them with?I thought that was everybody did these days(ok, not really. that's what we tend to do, however :) )
