Whiskers Goodcomment Randy. Obviously you like it. Handy that there is space for plug sockets under the ZIF socket. I have done that myself on a transistor tester I built.

Whiskers GoodMan, excellent photos and instructions

Whiskers Thanksfor that, I was thinking of getting one. I don't think I will bother now. Is that piston operating a diaphragm? It looks suspiciously like it is as there is no pin in the piston end. I have an extremely old red plastic bodied one that still works so I think I will stick with that.

Whiskers Thanksfor those photos, really helpful for tinkerers like myself who likes to replace the non replaceable. It looks like a massive Lithium battery. 2450 so 24 mm diameter and 5 mm thick. I never knew such an animal existed with tabs or without. As the previous commenter says sorry for the circumstances in which this knowledge was gained. I should think it would last at last three years though.

Whiskers Iwould have thought that the two pins for the planetary gears per gearbox would be included as you are replacing the internals of your differential gearbox but not so looking at the details and pictures.

Whiskers Ifyou paid VAT as Banggood should have charged it you should not have to pay extra. If Banggood did not charge the VAT then you have to pay it to get your items. That's how it works in the UK. Check your Banggood invoice.
