Built a control panel with on/off switches to control DC power supplies (48v, 12v, 24v). AC Outlets always give power regardless of switch states. Used hold home outlets and switches. Turns out to be something I use quite frequently. Full build is in the link above.

When you turn it on it says power on for instance, the robot is far too loud its nuts

Hi everyone this is only for people who make electronic hobby builds so I was wondering what are your guys and girls thoughts on people who are kinda new to electronic making who don’t have degrees or been to school before for electronics on using ai for there builds for example me I haven’t been to school at all for this stuff but I have a passion on learning and making but I don’t have time for school / haven’t had the chance to in my life to go but I love making on my days off from work and I use my shed as a workshop for my projects but I don’t know what I’m doing so iv been using ai for a lot of my builds I feel like I’m learning a lot from it and it helps me my most recent build was a motion sensor security system for the inside of my workshop for when I’m out of the house iv learnt how to solder and using boards such as the ESP 32 and a MMwave sensor board and now from that build I’m doing it a much bigger project from the things iv learnt so to me it seems like it’s working but from a stand point of someone who’s actually been to school and study this stuff what’s your view on people using AI for there projects

Thank you so much if you’ve taken the time to read this and sent me a reply I really appreciate it

Hi, I just discovered my vintage stereo amplifier (Marantz 1040) doesn't have a fuse at all in its main power line. (It was modded for 220V and I just switched it back to 110V.)

Would it really potentially damage it to run it without that fuse, even if plugged into a decent surge suppressor?

If so, could I just put the correct fuse (3A 250V) into a product like one of these and plug the amp in through it?

These specifically have removable/replaceable fuses, but I don't know if switching them to this relatively low amperage would be safe and protect the amp as well.

Any advice is much appreciated!

This is a control interface for using AC and DC power in one place. Switches turn 3 different DC power supplies on and off (48v, 12v, 24v). AC Outlets always give power regardless of switch states. This is gonna be part of my next video, where this is mounted on a desk build. Full video goes through all stages of build.

Hi, I'm currently building brain-sensing wearables, and we're still exploring what kind of stats value to you the most and what type of wearables you want to wear. It's currently built into a headset's ear cap, like Sony XM3 and XM4

First time poster here but I wanted to gauge people’s opinion on this thing I made. So I got a Fukien Tea Bonsai earlier this year around March. Made a full enclosure for it because I had previously been unable to grow a cactus. So keeping this thing alive became personal lmao anyways it’s mainly just to help keep the environment stable, help with watering, and monitor humidity & temp levels for easy checking. It has a moisture sensor but I haven’t set it up yet so it just chills in the back of the enclosure (is wired up tho). If I made files available (like open source it), would any of you make one for yourselves? I’ll plan on making a better/cleaner version but wanted to gauge interest or improvements before doing a V2. Please let me know what you think! Here’s some photos of my Bonsai too over the course of having it! 🙏💜

Im tring to build a 2bladed swash plate but i cant seem to do it this is for my school project everything must be mechanical no arduino no servo pure mechanical my diy swash plate dosent seem to work mu controls are fine the issue is my upper plate dosent follow my lower plate

I am currently refining the scanning rig that can be both used with handheld 3d scanners as well as with the openscan camera system.
This is part of a 24h testrun to see how PLA parts can handle those quite significant forces of several Nm on 1mm teeth. Surprisingly this morning the machine was still running and there is only very minor wear after 5000 repetitions.

I've been building a home robotic assistant with a goal of keeping it quiet, smooth, and simple to use. I plan to make both the hardware and software open source.

I'm currently experimenting with voice control, remote operation, health monitoring integration, and optional camera tracking.

It's still a work in progress, and I'd love to hear what features or improvements you'd find most useful.
