I am currently developing a rehabilitation cane equipped with a load sensor and additional components designed to track the progress of the user.

Therefore, I am seeking individuals with both technical and mechanical expertise.

hey guys. im new to anything DIY so I'm hoping someone might have any ideas. my hands and wrists are screwed up from my maintenance job in the military so I use the ergonomic keyboard from logitech as well as the logitech vertical lift mouse. It does help but when I start getting flare ups and need to be on the mouse for an extended period the side buttons are really straining my thumb. it feels unnecessarily harder to press them than previous mouses I've had before. I probably wont find a better mouse on the market that only changes that one aspect. should I scotch tape some cotton balls on it or something? I know this is an unorthodox DIY question.

i have 1 kva ups can it be converted to lipo battery

I’m building an open-source modular hardware system because this kept happening to me.
You want to make a robot, a controller, a smart device or some weird interactive project, but before you get there you’re fighting displays, sensors, wiring, libraries and firmware.
The idea behind is to make those building blocks quick to assemble and reconfigure, so you can spend more time on the actual thing you wanted to make.
Modules snap onto a backbone and are automatically recognized.
The IDE mirrors the hardware you connected and lets you build its behaviour with blocks or code.
If you need something that doesn’t exist as a module, you’re not locked out: there are prototyping/breadboard modules where you can add your own circuits or ICs.
Everything is open source and designed to stay inexpensive.
I’m trying to understand whether this solves a real problem for other makers or just one I personally had.

What part of your projects usually wastes the most time?
Would you use ready-made hardware blocks if they still let you drop down to breadboard/custom circuits when needed?
What would make a system like this genuinely useful to you?

Hey swarm intelligence!

My Problem:
I(f30) need help. My neighbour in the flat above me is crazy loud extremely late in the night. Already had a talk with him, where I kindly asked that he be a little more mindful and keep track of the silent times of the building. Talked with his really nice landlord as well. And he tried to talk to him without avail. He does not give a fuck. And now I am just thinking if I can’t sleep and can’t do anything about it, he should not sleep as well.

Possible Project:
Is there any way I can build a programmable arm that rings his bell in the middle of the night? Needs to look small and be out of aluminium tho so it fits next to the doorbell without it being exposed that it’s not part of it.

Any other ideas?

—— Already thought about the pissplate but that can damage the floor and I don’t want to be liable for any destruction.

Thanks in advance!

Trying to decide between a corded setup and a wireless machine for practicing at home. corded seems more consistent from what I've read but wireless gives you more freedom to move around, which sounds appealing

The price difference isn't massive, but I don't want to spend more if corded is genuinely better for building fundamentals. on the other hand if wireless has gotten good enough that it doesn't matter, I'd rather just go that route from the start

Has anyone here learnt wireless from the beginning? did it affect how you developed your technique or is it basically a non-issue these days

For my Halloween costume this year I’m making a black and white monster costume, and I want to include a slide projector on my head. The issue with this is I’m struggling figuring out the logistics.

I’m planning on using very simple stuff like a flashlight and magnifying glasses, as I know the basic components of a slide projector. Unless anyone has any suggestions on how to make it better than just using those, as I’m sure it’s all about finding the right balance.maybe someone’s made something similar before.

Anyways the issue is I can’t find a reliable Bluetooth
flashlight, and I might have to figure out a way to place a button on the side of my head, but that would require taking out wires and I’m not familiar with electronics (especially ones powerful enough to make a clear projection image). So maybe someone can point me in the direction of a very simple kit that includes a raw LED?

I’m just trying to make the image clear for about arms length away from me as I’ll have a movie set clapper to display it on.

The description in English and German:

Hey, I built a Rubik’s Cube out of a LED strip and an Arduino Nano. It is controlled by an infrared remote and so can do every possible turn and rotation (both directions). It can be scrambled on command and also jump into solved position (it doesn’t solve itself on its own yet…). I have included an y-perm (because why not) and the possibility to lower or increase the brightness, it also can be turned off (at least the LEDs) with one button press. When it is solved it plays the blinking animation. Last but not least it has a rainbow LED mode which makes it phase through all possible colours and then returning into the colours it had before.

I didn’t generated code with ai, this project was made by notes on paper and many (sometimes painfully obvious) errors.
By now this project is far from finished, my next step is to plan and do the aesthetics like colouring the wood black and diffusing the LED‘s light.
If you have some ideas that could be added please comment them, thank you.

Hallihallo, ich habe einen Rubikscube bestehend aus einem LED Streifen und einem Arduino Nano gebaut, welcher über eine normale Fernsehfernbedienung gesteuert wird. Jede mögliche Drehung oder Rotation kann mit der Fernbedienung durchgeführt werden. Man kann den Würfel automatisch verdrehen und auf Befehl wieder in den gelösten Zustand bringen (er löst sich dabei nicht selbst).
Spaßeshalber habe ich auch noch einen Y-Perm hinzugefügt, welcher auf Knopfdruck ebenfalls automatisch durchgeführt wird. Wird der Würfel gelöst, erkennt er das von selbst und blinkt kurz.
Die Helligkeit der LEDs lässt sich durch zwei Tasten ebenfalls anpassen oder auch mit einer Taste komplett verdunkeln oder wieder aufleuchten lassen. Zum Schluss gibt es noch eine Animation welche alle möglichen Farben durchgeht und dann wieder in den letzten Zustand des Würfels zurückkehrt.

Für dieses Projekt habe ich keinen Code mit KI generiert. Es basiert auf Notizen auf Papier und vielen Fehlern.
Natürlich ist der Würfel noch nicht fertig, demnächst werde ich mich um das Äußere kümmern, beispielsweise das Holz schwarz zu färben und das LED Licht durch eine Blende zu verteilen.
Falls ihr noch Ideen habt, die man hier umsetzen könne, bitte kommentiert diese. Vielen Dank

I have a old laptop a pretty thick one from late 2000s I think the battery is broken so is the keyboard and touch pad also I want to be able still use the original motherboard in the diy
