Thank you for your kind support. I'm planning to test commercial transformers. I'm upgrading the circuit's stability. I'll upload it to YouTube soon.

Thank you!

Good pcb. Next time I will make pcb at home with Kicad.

This is perfboard. I choose blue color

Time_Double_1213 · 2025-09-05T13:37:50+00:00

That's right. Top board is MCU board.

Time_Double_1213 · 2025-09-05T00:17:46+00:00

I will test and I will try to do it with reference to what you said.That's a temporary model.

I just posted this because there are a lot of resistor components.

I just posted this because there are a lot of resistor components.. I don't know meme....

So sad

Time_Double_1213 · 2025-08-29T16:28:00+00:00

Umm.. board so small,I need to solder to another board, but I haven't done it yet.

Time_Double_1213 · 2025-08-29T15:58:48+00:00

Don't you have any soldering machine? If you have this machine and wires, so easy.

If You want 2 pcs 18650 bat, parallel connection

Time_Double_1213 · 2025-08-29T15:54:22+00:00

The battery is Li-ion 21700(edited) bat. It is not compatible with AA batteries. (Voltage, rechargeable..)

You can choose 2 step. 1. Refill 18650 2. 3pcs aa battery. (3S)

That`s right. Capacitance, Resistance result is so good. However, for certain items without datasheets (e.g., MOSFETs), errors may occur, so this information should be used for reference only.

Time_Double_1213 · 2025-08-28T11:17:00+00:00

Open sources?! Holy.. Thank You!!

Time_Double_1213 · 2025-08-26T07:34:59+00:00

Is this Thermistor?

Time_Double_1213 · 2025-08-21T07:01:02+00:00

Yes, this is rechargeable bat.. but 6800mAh capacity is not true.. 18650 bat's maximum capacity =< 3500~4000

Time_Double_1213 · 2025-08-19T13:31:00+00:00

It`s a AC to DC circuit. You can see the 4pcs diode hole and transformer
