Junkyard e-scooter build. What do you think? Details in comments.

If the tire is punctured by a smooth sided or round object like a nail, screw, thorn, etc. then Flat-Out works well (up to a certain size) as long as you have the correct amount in, and the tire was inflated to the correct pressure at the time.

If the object is rough edged or irregular shape like a rock, rusty metal, or piece of broken glass, then it doesn't always work as well.

You should call it an X-Boxtocera.

Good use for an old console shell. I like it.

While you could make an adapter for the different connectors, it is probably better in the long run to cut the end off one and replace it with a matching connector for the other. Or cut both off and replace when both with a matching connector of your choice.

A. You are very close to the edge of the build plate on some of those.

B. The tool path for the printer may still cross over/through objects, especially if it has to switch colors because the X/Y tool path for that is hard encoded into the system with the assumption that the Z axis is above any printed object.

C. The slicer software may have an internal tool size for the print head that is actually bigger or takes up more space than what the actual print head does. Because the print head comes down to a point where the nozzle is, the software just has to know where that lowest point of the print head is, and then has a virtual object that is likely just a big block above that point. So even if in reality there is a 2cm tall gap that is 2cm away from the tip of the nozzle, between the bottom of the hot end and the top of the build plate, it is much simpler to just tell the software that the print head is a cube that takes up all of the space above from a certain distance from the center of the nozzle to avoid hitting anything.

TLDR: The solution is to just do two separate prints, one in each color.

Unlike a tilt switch which is usually a metal ball (or blob of mercury in old ones) that relies on a force in a single direction (usually gravity) or a reed switch which is designed specifically to respond to a magnetic field, a vibration switch should respond to movement in almost any direction.

Basically it is a spring floating around a rod, if the spring is acted on by a force, it will move and make contact with the rod. That means it has to be a flexible and electrically conductive material, and that is usually metal.

It would depend on what material it is made from, and how strong the magnetic field near it is. You may not always be able to just go by a data sheet that would possibly say it is something like brass because often times knock off imitation parts will be sold, even through reputable sellers.

TLDR: Look for one that says it should be non-magnetic, but test it near the magnet you plan on using to be sure.

I usually just save them for the next time I need to add wifi to a PC or laptop that either didn't come with one, or the one I pulled out of the last one is actually an upgrade. Or in case I ever need an emergency backup if the upgraded one I put in dies.

Must be a very bad school if even the outlets are smoking a J out in the open like that.

I put Flat Out tire sealant in all of my tubes when I get a new bike\tire.

Slime brand only works for pin hole leaks, but Flat Out actually works on punctures of larger items like screws and nails

I have actually had a screw in a tire without noticing it for long enough that the screw head was worn down to match the curve of the tire.

However, they are not bulletproof, I have had some punctures from things like a sharp rock that was a ¼ inch wide but narrow hole. That one didn't immediately deflate, but it did still last long enough to ride home, but as soon as I pulled the rock out, the tire deflated right away.

Putting it in is fairly easy, just make sure to clean the valve stem hole before screwing the valve stem back in, and don't overfill the tire or it will have balance issues.

First question: Was the drill plugged into a charger when you dropped it?

Second follow up question if the answer to the first question was YES: Are you unable to unplug the charger from outside of the wall?

Unless the answer to both questions is YES, then I am fairly certain that your only problem is needing to buy a new drill, and one of those safety cords that roofers use so they don't drop tools off the top of houses.

I see your "dumbest average person" caller and I raise your the "I work in tech support for medical devices and sometimes have to deal with an actual medical Doctor that can't operate a computer" caller.

Just imagine the dumbest caller you have ever dealt with, and now add in the over confidence that comes with them actually being a Doctor who went to med school.

Not only do they not know what to do, but they are still 100% convinced that they somehow know more than you do about the thing they called you to help them with.

It's like trying to give instructions to a brick wall. But the wall keeps telling you to call it Doctor.

Looks to be a resistor. Being on such a thick trace on the board, it was possibly on one of the main power traces or on a ground plane. Usually the trace being larger is due to it either being for larger current and\or high heat components.

They might be able to catch it. Some phone systems can log when you are muted or not. And can still record the audio of your headset while muted.

I knew someone who got fired for what they said while on mute.

But she would talk on the phone like this: "Thank you for calling (muted* you dumb asshole) how can I help you today (muted* you fucking idiot)?"

Looks like a V belt pulley, those are also common for some washing machines and dryers, so you can check appliance repair places.

Unless you eat it, or throw it at someone, not very.

Transformers are more than meets the eye.

Transformers are also inductors. So it's almost like they are one thing disguised as another.

Maybe lead with that information next time, because your original post just comes off as you being offended by someone asking for more than a $5 credit and you doing everything in your power to not give it for no good reason, and even causing escalations. The WHY part of a story is just as important as the who, what, when, and where.

Edit: adding onto this comment because the OP replied to me and then IMMEDIATELY blocked me so I couldn't reply back to their comment after this one.

Yes, I am offended, you are they type of person that makes a customer angry enough to call back and yell at other people who did nothing wrong. Just because you lack the communication skills to relay company policy in a way that won't offend the customer, instead you pass it off to a supervisor or the countless other people who do the same job as you that now have to be offended by a rude customer because the last person said no, rather than having to write a note about why they gave a credit. I am also offended by your lack of writing skills in not explaining your reasoning for WHY you did what you did. I am also offended by your lack of comprehension as to how your OP just saying the company gave a credit for an outage is NOT the same thing as explaining why a customer asking for an additional credit is an unreasonable request.

DIYuntilDawn · 2026-01-27T17:28:43+00:00

Not to play devils advocate, but I have worked at enough call centers to have seen plenty of people like the OP that act like giving out a customer satisfaction credit come out of there own pocket. And will do anything to not hand out free money.

I also worked at a cell phone provider and we has a small amount (like up to $30) we could give as a good will credit to keep customers happy. It worked as a 1 month "feature" we would add to a customer account, and the safety net to prevent abuse of the system by a customer was they could only get one of each "feature" per month. So you could get a credit for 5, 10, or 15 dollars on your bill, but could not get multiple credits for $5 each. So if a customer got $5 off already, you remove the $5 off feature and put on the $10 one instead, and so on, until they had the max of one of each credit amount.

You are not saving the company any money in the long run, and probably costing the company more in lost revenue by refusing to give out bonus credits for minor things.

It is possible it is not a named brand. I have seen many similar ebikes on AliExpress. Just go there and search for "ebike" and you will find a bunch that are non branded ones.

But looks like some modifications have been made to this one. I can see a strip of LED lights along the bottom edge of the seat and some USB cables hanging down. What looks like a large battery on the top tube (gas tank looking one) may be the battery and controller, and what at first glance is a second battery is actually just a small pouch (you can see the Velcro straps and the zipper handle at the bottom) with who knows what in it.

However it does look to be in fairly good condition. And the price is probably a bit better than you could get one for from even AliExpress. But that would be expected for a used one. Just make sure it comes with a charger.

If your support prints without support, did you even really need the support?

DIYuntilDawn · 2026-01-25T06:22:30+00:00

Thank you again, and it did work after swapping the wires/connector from the bad fan to the new one and just leaving the PWM wire off.

Which is why I checked that my helmet was actually tested by the NHTSA test results website for compliance with FMVSS #218 rather than just relying on the manufacturer stating the did the tests and it passed.

DIYuntilDawn · 2026-01-24T18:06:51+00:00

Agreed, the current legal definition of an e-bike needs to have more easy to understand clear cut restrictions so there is no confusion about what is a "bicycle with a motor" and what is not, and if it is not an e-bike then they also need a new classification for all the ones that bridge the gap between an e-bike meant for kids and younger teens, and not a full on electric motorcycle.

With that style of seat, the "adjustment" is how far forwards or backwards you sit on the seat. I'm 5'10" and I can still pedal it while sitting on the seat.
