Q: Has anyone run these pumps from 12volts? Will they run or burn out?

Задавает Libra на 2023-08-24 04:34:36

maurits The pump is marked 4.5 - 12 volts, so 12 volts should be okay.

Q: What is the third pole on the female contact?

Задавает Arnror на 2022-09-01 03:35:28

maurits The innermost negative terminal on the socket is connected to the negative pole of your equipment's internal power source (usually batteries), and the outermost ("third") negative terminal completes the negative line to your equipment. When a plug from an outside power source is inserted into the plug, it disconnects the batteries, and supplies its own power to your equipment. (Of course the plug's positive terminal (the centre one) must be connected to the your equipment's positive line.)

Q: Why there is no UK plug?

Задавает Fai00 на 2022-02-01 11:20:23

maurits It seems all the ones with UK plugs have been sold out. Ust get yourself a US to UK adaptor plug. Voltage will be OK since the AC adaptor is rated for 100 to 240 volts.

maurits It seems BTMate is an iOS (Apple) only app. Maybe a similar Android based app will also work.

Q: can this work to engrave on gold/silver jewellery?

Задавает BG131049114 на 2021-12-27 08:29:37

maurits Lasers generally do not do well on reflective surfaces, and metal could be a problem for a weakish laser like this. Maybe one can experiment with temporarily painting the surface with paint, and remove it after lasering.

maurits No, if you look at the picture of the back of the circuit board, you will see that those holes are connected, thus the same terminal.
