voltage

I am working on a 6 layer trim based on Nold's Miicro. I finished the trim, tested the resistances and everything seems good to go, but when I have 5V connected to AV it won't turn on. When the 5V is disconnected (white wire shown below) it turns on, evidenced by the CPU heating up. I have tried...

Hi! I have tried for a few days now to get my wii to work after being trimmed. Stupid as I was, I trimmed it before moving U10, so I don't know if that is the problem or not. I managed to desolder it losing only one leg, and that leg being one of the ground legs (the ones on the side with 3...

Story time: I trimmed the board, relocated U10, and connected voltages to the board from the PMS. The board booted, to my delight. But then, disaster struck. I was considering removing the LDO to save some room in my case, and so I was probing with my multimeter to find where the 1.8 V output...

I don't know which power distribution boards to use for a portable wii. Will one from a gamecube work? If not what are some good PMS boards to use?

I am redesigning a mini-arcade machine, and I would like to make it rechargeable. It requires 4.5v of electricity. I was going to use a pth08080wah regulator, but I was thinking: would I be able to just use a rechargeable 9v battery and a simple 2-resistor voltage divider instead?

Hi, before trimming my console, I wanted to make sure my custom regulators are working fine. These are my readings from the four regulators (PTH08080WAH): size of resistor used - output voltage reading from multimeter 82k - 0,995 V 33k -...

I've been reading a lot of stuff on the site and lurking around a lot of the other worklogs of complete noobs like me while collecting parts and tweaking my design. But I've actually done some work on some things and I like feedback so, In the words of our favourite plumber, here we go... BOM...

Hey guys! I've decided to make this a project for myself. With my determination and local connections, I have faith that I will eventually fix this portable. As known from my last thread, the N64 engine does not like to activate with the rest of the machine majority of the time. I opened it up...

Hi! So I've started work on a GCP and wanted to ask a couple of questions! 1. I have a DOL-101 Motherboard, can I directly plug in a 12v battery or do I need to step the voltage down to 11.1v? If so, how do I do that? What's the easiest and safest way, because I'm not that experienced yet :D...

So I'm curious, what does everyone do for resistor values regarding the pth08080w regulators? They require some pretty oddly specific resistance to get the needed voltage for wiis so I haven't been able to find singular resistors with the correct values. I haven't actually strung them together...

I am referring to the circuit inside of the portable and how can you add a battery life indicator to tell if the battery is charged or dead? SOLVED:
