Yes

Crosshead, just normal screwdriwer. It is better open from back. There are lots of screws, but it is better. Replace fuse and tighten DOOR SWITCH screws. There are THREE door switces. Up, middle and bottom switch mount screws. They get loose over time.. After that device is fixed! Door switches need to operate simultaneously. If not, the fuse blows, it is safety system. No need to replace anything else but fuse.

@SnapTinker Thanks for your reply I checked the fuse and its working seems the door switches are stoping the microwave/oven from starting there are 3 Next is to find how to verify those

All switchers tested with multimiter and working and both fuses as well not sure why it doesn't allow to start after I choose the program Only start button is not working

Is your devise totally dead? Does the light work, does the control panel power, does the motor spin? I would check the thermal fuse, but you have probably done that? If control panel gets power, the start button may be broken?

@SnapTinker device is not totally dead it start you can choose the program .the control panel is working fine except the start button (touch panel ) .thermal fuse tested and working fine. Unless there is a hidden fuse, I don't see any problem. Will try to add pics later on

All slots work independently. You can test four slots simultaneusly, or only some of them.

Keeping the angle is impossible freehand. Use table and wood blocks/anything as a support for elbows and scissors. Angle must not change during process. Practice and perceverance will finally pay off.

I looked at your spot welders, heavy duty industrial machines. I bet they work well! Probably too heavy for hobbyist battery builders?

You're completely missing the point of the video.

If you set cc-limit at 3 amps, voltage drops at 3 amp load. That is how cc/cv works. Below cc limit voltage should not drop ( except measured at cable ends because of cable resistance). If cc limit is above 3 amps, your device is faulty or this device does not function well at max values. I cannot test myself, I don't have proper test load.

Lii-500s is very fast, but it lacks storage function. It needs 12V power source but Lii-M4S-works with any usb charger. Lii-500 costs more. You make choice which values more to you.

Pet stores does not normally have much tortoise supplies and you must buy online. Bigger caves are difficult to find and it is difficult estimate the size online.

I have not had any problems with it. It delivers 10A as expected, but I did not have a long time load test though. The only issue is the ripple current of usb-port. Can I fix it with a capacitor? Some day I'll test that.

I soldered a 100uF capacitor into usb output. It solved the ripple voltage problem. Easy fix!

This is probably cheapest charger with test and storage function.

I ended up buying new pods, then learned about a recall. I got new AirPods from Apple (pods only, not the case), this recall is probably still active. Google :"Airpods pro program for sound issues".

@@SnapTinker Yes, I knew about the recall service, and I also know that it's for three years from the initial retail date. The recall program itself continues, but most users postpone it because they think it's going to cost them after three years or even if it's in trouble, and then they know the news of the recall belatedly after three years. In my case, I knew it was an AirPods subject to recall because it was created at the time of four years, but I couldn't get the service because it was normal during the recall period. I can buy a new one, but I repaired it myself because it's pretty cheap and easy for me, to fix it myself.

@@Aeh5oodeaQuwow how do you fix yourself?

​@@emirhannsezgin replace driver, i posted method and tool at Thingiverse, search "AirPods Pro Repair Tool"

You should make youtube video for that! Where did you get a correct spare part?

Yes, it is slow, but It has usb-c. I'm trying to get rid of separate power adapters. There is Liitokala fast charge model, but it has a separate power adapter. I hope that some day they'll utilize usb-c capacity, which can reach up to 100W.

I use dedicated bike chain lube, but cheap one. Washing chain wastes a lot, most of oil comes off with dirt. Most important is to lube often.

Thanks much!@@SnapTinker

Storage mode is for Li-ion batteries only. NiMh batteries must always be charged full. Inspired by your question I made measurements for NiMh charge mode: charger makes short current pulses at one minute interval after termination. So it does not ruin your batteries.

@@SnapTinker Thanks for this. :) It’s not as fully functional as the Lii 600 but it is less expensive. Nice :)

You'll need to hold the button down until screen flashes dark. You need to repeat until that happens. Watch the video at 2:18. This is a design flaw of the charger which we have to bear.

I have blocked the lower part of sides with wood strip to help that. Also, I take him out from cage when he wants out. Usually he is satisfied for some time, when I take him back to cage. Cage is anyway too small for him to stay all day.

I have only one tortoise, you'll have to ask local pet shop.
