I Bought two Milwaukee MXF XC409 battery backs for a good deal on Market place with intentions of using them for my kids power wheels upgrade. Soon realized the battery's must have a safety feature where they wont produce power unless they are attached to one of the MX line of tools.

Has anyone tried this before?

Thanks,

I want to make a custom wrap for my ski helmet (Arizona ice tea for me and red bull for my friend) I have access to a full cmyk vinyl printer/cutter that I think would work but I was wondering if anyone hat tips of could help with how to make it.

I'm working on a clock that plays a snippet of different tracks from Animal Crossing New Leaf, every hour on the hour. I was inspired by the National Audubon Society clock, which plays a different birdsong every hour.

I'm having trouble finding informartion on how to go about designing the electrical and audio component, and especially on writing a program. I have some background circuit/PCB/soldering experience, but I've never made my own circuit before.

There's some other complications: The NAS clock cycles through 12 different sounds, while my clock will be 24 tracks. I'd also like to incorporate a switch on the side of the clock that can be used to play a different set of recordings, as there's different versions of the music depending on the weather in-game.

Any resources or advice is greatly appreciated!

Ok so I've been working out of a small workshop for a while now, renovated 20ft x 11ft space, walls insulated and old metal shed door replaced with pvc door.

My issue is heating, I have nothing other than the small 3000w fan heaters which here in Ireland are expensive to run.

I don't have any wall space nor any plumbing in the space to add a traditional radiator.

Can anyone recommend something potentially ceiling mounted? Electric if its more efficient that could heat the space? Most of the year isnt bad but decDecember through to February the temps aren't great for papainting projects.

This German fellow made a really nice wired lamp using a glass block.

I was curious if there was a rechargeable LED module that would fit in the wood base instead?

It's a marble machine with copper wire.

How rigid do you think it is?

Is the wire bent by hand or some type of machine or design?

How thick is the wire?

I've always wanted to make something like this - with a similar aesthetic - and curious if people have ideas?

Thinking of something I can use in my garage. Something similar to https://www.aliexpress.us/item/3256806895731257.html

Anybody with experience chime in?

I'm building a mock school bus driver setup from a racing wheel stand (gaming). I want to build a working stop sign and crossing arm that can be activated when the driver turns or pulls a lever.

I have a 3D printer and am reasonably capable with tinkercad. I'm struggling to find any per-designed mechanisms to translate the lever's motion to the sign and the crossing arm. I'm imagining using either a loop of string or a set of dowels to transfer the motion to the hinged parts. The simpler the better.

Are there any suggestions/links for some printable parts? Any specific part names I need to search for? Any example projects I could use for reference?

Hey all!

I've been looking for old instrument parts that no one wants. Specifically for any sort of old xylophone wood keys that are not that pricey.

I'm planning to make other machines that make music out of them, and i haven't found a good place to find old instruments that are busted... any help is appreciated!

I'm looking for small projects accessible to me with... Just about zero soldering skills/knowledge to get me from "probably gonna burn my house down" to "I kinda know what I'm doing" for an e3pro upgrade I'm working towards. I'm willing to buy Arduino/pis and just want something cool (and not extremely expensive) that'll teach me the basics. I'd also love something that I can print parts for. Any ideas/suggestions?

I just purchased a new home and the buttons inside the garage to trigger the garage door openers are these sad little door-bell reject white push buttons from the 70's or 80's. I would like the replace them with big durable beautiful buttons. I've found the Apiele 22mm machined aluminum buttons, which are beautiful, but fully 28mm from panel to the tip of the terminals. Can anyone suggest something equally aesthetically pleasing (and rugged) that is lower-profile?

My son (18M) has been into maker-type things for a few years. He owns 2 Ender 3 printers and a Resin Printer. He also makes resin molds and pours gaming dice which he has a pressure pot to use to remove bubbles. He has dried flowers to put into resin pours as well.

He's away at college now but I would like to buy him an impactful gift for Christmas that lets hi know I support his hobbies. I don't want it to be something 3D printer specific because I have joined him in that hobby and I don't want to give the impression that I bought something for "us" to use.

For example, is there any point in looking at laser engravers that cost less than $250US? The Comgrow Z1 looks capable.

I appreciate the input!

I'm going to build a rig that will attach to the rear of a picture frame and strike it from behind to break the glass (safety glass from a prop shop, rear cardboard removed). I'm trying to decide how large of a cylinder to get. Also open to other ideas to accomplish this. It's for a film. Trying to keep the footprint small too so looking for the right balance.

Thinking specifically of the trade off between bore size, bore length and PT size. Longer stroke? Shorter stroke but larger bore? Stroke length not too important because air exhaust will create a bottle neck either way?

Thank you!

I used 3mm aluminium plate, some brackets, 3 pieces of wood, a door stop and 4 drawer handles for the feet. Constructive criticism welcome.

I'm a long time maker, right to repair activist, homelab enthusiast and general tinkerer. I have a healthy stock of parts in my shop becuase when I need a one off part, I pay the extra $2 to get a dozen of them instead of one.

With the potential economic impacts of tarriffs, stronger demand to maintain existing appliances, or supply chain hiccups like we saw during the pandemic, what parts, tools, or matierials would be most benifical to stock up on? I thought about stocking up on PLA but there's a decent number of US manufacturers.

My inability to get a Rpi for under $100 really sticks in my mind from 2021/2022 so I've personally bought a dozen of each dev board I usually use, some common basic breakout boards I use, and a new soldering iron tips, boost/buck converters, some chips I use often.

Is there anything anyone is stocking up on or buying now in advance of supply chain hiccups or increased costs?

TL:DR Is there anything you guys are buying this season? I don't want to have another project with no way to build it again.

I posted something here about needing help with how to do these buttons. I figured it out! I used a button that was already waterproof, and attached the cats (they were going to be bells but now they’re cats) to hinges and it works just fine! We used a raspberry pie, an outdoor speaker, some waterproof buttons, and lots of MDF and paint and it all came together!! Let me know what y’all think.
