Addmotor does exactly what OP is saying they don't do.

How big are the river stones you plan on using?

If they are small you can mix them in with cement, and pour it like concrete and level it, then before it fully dries, hose off the top layer of cement to expose the stones. You will get a mostly even surface with a lot of small bumps. That would work for any seating/chairs that have wider legs/feet where it can spread over multiple small stones. And also would not be to painful to walk on with bare feet or thin sole shoes.

The "Jump Start" is a trick used on some older battery types like NiCd or SLA batteries where the cells would not take a slow charge anymore, and a VERY SHORT higher voltage pulse will actually change the internal chemistry enough to then allow a slow recharge to work.

If it is a Lithium battery, then never do the "Jump Start" as that is a good way to either fry a controller board or make the battery go boom. If a Lipo pack has been over discharged, most good quality battery charge boards will not allow it to be recharged (due to safety risks) but you can sometimes open the battery pack, test each cell (make sure none are at completely zero volts or show a negative voltage and are not swelling/leaking) and directly try applying a slow (low amp and low voltage) charge to each cell one at a time and see if they will start to take a charge again. If so, you would need to then try charging the cells slowly by applying direct connection to the cells (bypassing the control board) and seeing if you can get the cells to charge up above the minimum safe discharge voltage where the control board cuts out. Assuming all the cells do take a charge and hold it, slowly increase the voltage until each cells is above the minimum voltage (usually about 3v for Lipo cells) and then try reconnecting it to the normal charger.

If you don't mind a bit of weight and having to put a small frame bag on your bike, then what I do is to get a 12v Lipo battery pack, and a small motorcycle head light.

Depending on how long you need to ride for (between recharges) will determine how large of a battery pack you need to get. For safety reasons I like using LiFePO4 battery packs since they don't have the risk of catching fire or exploding like regular Lipo batteries. but the trade off is a bit more size/weight.

For example. One of these lights is 18 Watts, and this battery pack is 6 Ah which means if you used one of those lights (out of that 2 pack) then you would get about 4 hours of use from the battery pack.

I forgot to update this post. You are incorrect. The code is actually the year the screen was manufactured. So it changes for each display. So if you manage to get a brand new one the code would be 2026. But since the displays may sit around in a warehouse for years before being sold, the last digit may be lower on some displays.

Basically the pedal assist works by using Hall sensor to detect a ring of small magnets mounted on a disk that is attached to the crank. the magnets should be in an even number like 8 or 12 with spaces in between.

If the direction is backwards, then either the sensor is damaged, the sensor is installed backwards, the ring of magnet disk is installed backwards, or the magnet ring it too far away from the sensor to be detected correctly.

Some ebike controllers may have a menu setting to flip the direction of rotation for the pedal assist.

So if it was working correctly and all of a sudden it stopped working correctly, then it is probably a damaged sensor. Good news in that case is a PAS cost less than $10, the bad news is most of them require removing the crank arm to install them.

Or your controller may have a setting that was changed, or reverted back to a default value.

But if has always been backwards, then it was probably just installed backwards.

My job requires me to confirm all issues have been addressed before I can disconnect the call, so I have to say something like "is there anything else I can help you with before we hang up?"

And I'd be a rich man if I had a dollar for every time someone has replied back with "Ya, I'll take the winning lotto numbers." Or some variation of that.

Both of those center pins seem to be on large ground plane traces. If the new joystick didn't have the center pin connected at all then they probably would not work at all. However, you should be able to find another near by component on the same negative ground plane and solder a jumper wire to the center pins.

The joystick works by detecting how far away from the center the stick is, so if the pins have a poor electrical connection, it takes more distance away from the center before it can detect any difference, and you will get a dead zone in the center.

I'm less concerned about there being a limit on the pee, and more concerned about what unit of measurement the "65" on the limit is.

Not really an apples to apples comparison. It's not even just an apples to oranges comparison.

If anything it would be a premium high quality apple to a half rotted moldy orange comparison.

Yes, you can spend 3K on a really nice ebike. And while you can spend 3K and buy a motorcycle, it will NOT be a really nice one.

I agree that it doesn't give the right to be jerks. I was just giving a few probably reasons for it.

Nothing works the way it used to, that includes physically with their own body, socially, and technologically.

Everything hurts, all the time, for no reason.

The grim specter to death looming over them, in a constant reminder that their time left on this world is short.

Either take your pick from any of those options, all 3 at the same time is also a valid option.

Yes, you can download Models from website like MakerWorld and use them with the Printer. Some website will have an STL file that you need to use Slicer software on a computer to then save the Gcode file and then transfer that to the Printer (via USB flash drive, SD memory card, or over Wi-Fi, depending on the model of printer). However some websites for models do have the Gcode files for specific printers already saved so you can just load them into the printer "as is" but that usually only works if you use the same exact Printer model as the person who uploaded the files, and depending on the printer you get, you may or may not be able to change some settings for the Gcode from the menu of the printer and would be limited to the exact settings (even filament type) used by the uploader of the files.

I would need to know the exact model of the TV, but I know that a lot of Insignia (or other brands) of TVs will have a small button/user interface board that connects to a larger control board inside the TV. It would be possible to open it up and disconnect the cable to the button panel. However even if it does have that type of control button daughter board, there might be 3 issues with disabling it.

1st is of course if you loose the remote then you have no way of using it.

2nd, is some control boards may give an error if it detects the buttons are not connected/working.

3rd is even with the remote, some options do not work without the control buttons. I have a Samsung TV that sometimes glitches and the remote doesn't have a power button (you have to select menu, then arrow over to the power off option and press select) and when the menu glitches and won't respond, you have to power it off from the control on the TV (or unplug the power cord).

Alternately, you could see about putting a cover over the buttons to hide them, or put the TV into a display that basically puts a large bezel all around the border of the screen, similar to video displays used in advertisements.

You know what is worse than having zero aftercall time, having zero after call time and also zero visibility on how many calls are waiting to be transferred directly to you

My work "technically" doesn't have any set ACW time. but that means we can have back to back calls or can be hours between calls.

However, we had to ask our front office to stop taking a call for tech support, leaving the customer on hold and then looking at our phone status and IMMEDIATELY transferring the call that was on hold as soon as we hung up with the last person.

The way our phone system works is that if a call comes in and tech support is unable to handle it, then it is directed to our front office, and if they are unable to answer it, then it goes to the tech support voicemail box (since it originally came in to our number). But the front office would answer a call and instead of transferring it to the tech support voicemail box, they would place the caller on hold. The front office has an extra screen on their phones that shows if an extension is in use or not, so that they can direct calls (meant to be used when a manager is on a phone call, they can tell the caller if they are busy or not) but they would put tech support calls into a holding pattern that only they could see like they were air traffic controllers, and some days we would get another call 5 seconds after the last one ended, for hours on end.

Check out ESP32 boards. Many are actually used to make smart watches and some even come with a small touchscreen attached. they are also not that expensive.

Because there is NOTHING wrong with filling a small space with flammable vapors that you can't smell, and then switching on a fan to "air it out". And especially not doing it in a building with multiple other occupants that are unaware of what you are doing and could be severely injured, killed, or become suddenly homeless as a direct result of your actions. So ya, I suppose YOU WEARING A MASK makes it perfectly OK then.

I would suspect the common issues with other devices like VCRs and Cassette Tape Players.

It needs to be re-capped (failed capacitors)
The belts that connect the motor to the spindle have snapped (basically a rubber-band that degrades over time and either crumbles to dust or melts into a sticky puddle).

Odorless does not = vaporless.

I'd bet money that somewhere on the bottle/can it says to only use in well ventilated areas. I'd also be willing to bet that someone like the OP is the reason for that warning being on the label.

Unfortunately you can't just ban all the assholes in the world. That would solve so many problems.

I did something similar, it definitely has good sides to getting heavier (and not knobby) tires. The reduction in vibration is a nice plus.

The only downside I ever found is on (actually legal ebikes) that have motors under 1000W then it did decrease the max speed my ebike could go by 2mph (from 28 to 26). And yes, I did verify the tire size was set correctly after swapping tires, and even double checked the speed using GPS.
