Quote from: crorris on April 12, 2024, 05:54:20 AMThere is another option - CO₂

As a youngster we used a lot of CO₂ for airsoft pistols and I have learned to hate them for their single use purposes. But I do agree that they are a lifesaver when you are in the middle of nowhere and no airpump.

For some reason the pictures didn't upload to my post. It's a custom made solution that uses a basic horn (Amazon link). Then there's a 3D printed case that houses the charging circuit and battery.

There are lots of products available that offer a turn key solution of this, I just wanted to make my own.

Ah. It all makes sense now.

I carry a small manual pump that mounts under my water bottle holder. I don't recall it being too much effort to pump up a 20" fat tire.
A CO2 cartridge seems to me the poorest choice, if you have a chronic leak. What do you do when it runs out?
At home I have an 120V AC-powered pump for the cars and the bikes:

And, since I can never trust the gauges built into pumps, an inline pressure gauge with a handy little bleed valve:

What? Completely deflate the tire, push the bead in along a short section, pull out the part of the tube with the hole (if you know where it is). Patch it, push it back in and re-inflate.

- Custom Self Powered and Charging Horn
Very nice for getting car's attention. Custom 3d printed case that attaches to the front rack mounts. Charges with the USB port on the display. This took a while to figure out. It has a small 500mah battery that is kept topped off by the USB port using a small LiPo charging board. The button is wired to power the horn from the 3.7v nominal battery, which powers the horn. The horn is rated for 6V, so it's not as loud as it could be.

- Shimano Altus SL-M315-7R 7-Speed Right Rapidfire Plus Shifter

It looked like any ordinary horn. thanks for the extra info inside the unit. I will definitely buy one since it can be a standalone unit. I might even wire one up on my coworkers office chair.

I also liked the look of that shifter.

That ain't necessarily so.
I shave with razors that are 50-100 years old, they out-perform modern cartridge and disposable razors, and (most amazing of all) you can still get blades for them, at a cost of a penny or two per shave. I have a few modern ones too, but they're styled after the vintage ones and have interchangeable parts.
My 40-year old electric kitchen stove is primitive too but you can still repair it.

I just noticed that the automatically-added "Rad's New Lineup Is Here" final post is gone now.
Not that I'm complaining.

Quote from: Naranja_CT5+ on April 16, 2024, 07:53:35 PMIf you cannot find a replacement bracket why not try using a cellphone mount?

I don't think you could find one small enough for the UI Remote.
Also, the button-mashing subjects it to considerably more force than tapping on a touch screen.

One of my favourite (even more so than duct tape) DIY sekrit weapons is plumbers strapping. It typically looks like this:



Super strong, yet easy to cut with metal shears or bolt cutters and easy to bend by hand or with pliers. It comes in various widths and materials, such as mild steel, copper, and galvanized steel. Of interest for this project is the kind that is coated with PVC, so as to minimize scratching the finish on the handlebar.

The smaller holes should be big enough to get the threaded part of the screws through, but small enough for the heads not top slip through. You could also use washers with it too.

Maybe not very elegant to look at, but it should be secure enough until you find a 3D-printed one.

Or, you might get lucky and find one of these molded PVC pipe straps in the right diameter, or slightly bigger:

It should be on a shelf near the other kind of strap. If it's slightly bigger diameter then you can put a strip of inner tube rubber on the inside, or build it up with PVC tape.
[edit] Oops. It just occurred to me now that the part you are trying to replace fits around half the diameter of the handlebar, so it's only a half circle on the inside. The PVC pipe strap is designed to fit the full diameter of a pipe, so it's a half circle plus parallel extensions. A sheet metal one could be more easily bent to fit.

Oh - If you do have one printed, and it's printed with filament, have it be printed on its side (not upright like an arch), because the horizontal layers are more easily split than the other uh ... directions? ... dimensions?.
If it's a resin printer, then I have no idea.
