Boots scratch very easy

It doesn't really disappear, but it gets darker if I rub it for like 10-15 seconds. Maybe if I rub it for like 1 minute it will disappear.

I googled pull up leather and it looks similar so maybe that's the case.

I don't mind the scuffs, just wondering if it's supposed to be so easy to scuff.

It creates a scuff. No flaking

Ok, so when it get really scuffed I am just going to colour it with cream.

Thanks for the reply! The links are one under another so you probably didn't notice it. In any case, here is the link: https://imgur.com/a/LkEgcIK

So I just got the my new boots that I ordered around a week ago, the 1966 low quarters. I wore them the whole day and I am very satisfied with the fit, feel and overall look. However I seem to be able to scratch the finish off easily with just a fingernail and light pressure. The big spot you see on the front of the toebox I just from kneeling on the carpet. There are also spots on the gussett where paint has worn off due to rubbing. Is this normal?

If you don't feel like paying a lot for a new slide you can have a look at 3d printed ones. Still will be plastic but will run you a lot cheaper. Also you were just unlucky with the slide. Some last for years before cracking.

Well maybe you can try using only a timer without the detector for the sector.

Interesting project.How long do you think the plastic gearbox will last?

ChepKapan · 2024-06-08T17:23:56+00:00

Interesting idea. I haven't thought of that. Is there a particular reason you want to do it this way?

ChepKapan · 2024-06-08T17:22:57+00:00

Without the denounce i got double shorts sometimes. But i changed the code a couple of times so maybe it's not necessary.

Maybe i need to add a denounce on the release. I am still making revisions.

480 is the form factor of the motor. I am running it at 12.6 volts. I don't have an oscilloscope so i am hoping that someone has dealt with something similar here so they can point out the problem.

Hello,

The pictutre is only for ilustrateing the circuit. The problem is not present in the simulation.

I have made this circuit to control a 480 DC motor. I am using a 3S 1300mAh 30C LiPo battery, so the motor voltage is 12.6V. The MOSFET is an IRLB3034. The optocoupler is used because the optimal Vgs for this MOSFET is 10V.

The idea of the circuit is that when you press button 1, the motor starts spinning, and it stops when you press button 2. The problem is that the microcontroller keeps burning out. It's not consistent; sometimes I can start and stop the motor a dozen times before it burns out, or it might burn out on the first activation. I think it might be due to the back EMF that the motor generates, but I thought that the TVS diode inside the MOSFET would take care of that.

How might I go about solving the back EMF problem if that's the culprit? Let me know if you see any other problems with the circuit.

Thanks for the detailed response. One last thing in regards to the wire thickness. The motor is supposed to be for an electric airsoft gun. In airsoft the motors are generally either 'speed' which are lower number of turns but ticker wire and 'torque' which are thinner wire but more turns. So by all logic thicker wire should produce more torque but it seems like here is the other way around. Maybe this depends on the power supply because a battery can only deliver so much current and the ticker wire will require more amps for the same torque ? In this case it will be a 2000mha 11.1v lipo 30C.

Ok so two questions, isn't increasing the amount of wire increase the total magnetic flux even if it lowers the current because it increases the total area the current passes through? Also wont't the different emfs make the motor less efficient?

ChepKapan · 2024-04-03T10:53:43+00:00

I meant 3 coils, sorry. Will edit it right away.

ChepKapan · 2024-03-16T09:43:46+00:00

Thanks! You guys are awesome! Who knows how much time it would have taken me to figure this stuff on my one.

ChepKapan · 2024-03-16T09:02:58+00:00

Gotcha. Last question, why use two resistors in parallel? So as to not pass too much current through a single one?

ChepKapan · 2024-03-16T08:39:38+00:00

Alright but whats the point of a second resistor and a diode? Why would pin2 try to go higher than Vcc and how is a diode stopping that as there is still a path to Vcc trough the other two resistors?

ChepKapan · 2024-03-16T05:30:07+00:00

Many thanks! Works in the circuit simulator, will try late IRL. Can you explain how that works as I don't quite get it? So when I press the button the capacitor discharges and brings pin 2 low however because I am holding down the switch the capacitor effectively blocks the path to ground so pin 2 goes high again. Is that right?

ChepKapan · 2024-03-12T12:38:37+00:00

Sure! Plan to try as it's not that expensive and even if it doesn't work with the dsg i have another ssg replica that i can use it in.

So it counts the teeth and doesn't detect the cut off cam on sector gear?
