    Question GameCube Portable: Add Battery Voltage?

    Hello! So, I have this old pencil sharpener from when I was in high school that I'm trying to make into a portable GameCube. Believe me I know it's not a good idea in the slightest. I'm going for "lets see if we CAN do it," not "let's actually make this a practical game system." That's all fine...

    Hey, absolute beginner here! I want to build a PS2 portable (from a SCPH-75004), but I have some concerns. I'm looking to slowly work my way into portablizing the console, starting with making it independent from wall power. Now what I need to know is, how would I exactly do this? I know I'd...

    Discussion Custom BMS Balancer

    I thought about creating my own 3s Li-ion balancing/charging circuit to place on my recent projects pcb. But after some research, I havent found any solid leads on how to approach something like this. For comparison, if you search for "DIY audio amp circuit", you get truckloads of great designs...

    Question Red Board problems

    So I hooked up the famous Red Board™ to my batteries, double checked the connections, and plugged it in. Problem is, one charger didn't charge them at all and the second one caused the red light to flicker quickly and the voltage to drop relatively quickly. The AC adapters have the same ratings...

    Question Thinner alternative to 18650 cells?

    Hi everyone. I'm not quite done with my current portable yet, but my head is already buzzing with new ideas for my next. I'm hoping with my next build I'll be able to cut back on the size for a much slimmer form factor. The question: are there good thinner alternatives to the 18650 cells? Off...

    Solved Batteries not Charging

    ey bois so, I'm making a battery pack with 18650s and I'm pretty sure I hooked 'em up right, as my mini chinese LED display rates the batteries at 8.06V (confirmed working from my old pack). But for whatever reason, my batteries won't charge. After reconnecting the the b- to b-, and the b+ to...

    Question Lots of 18650s

    I have a bunch of 18650s from various sources. Is there a method I should use to test their health before I use them together? Any rules about matching capacity? Also, is there a BMS (like the ebay "red battery boards") that would be suited to using many cells together? I'm not really sure...

    Question Portable Battery Pack in a Portable?

    I've got a question on the feasibility of taking a portable charger, say an Anker power pack, disassembling the pack to improve form factor, and using it for a power source. Is this possible? I've realized that spending $20 on a battery pack that already comes with a protection circuit might be...

    Question Wii Portable Battery

    So I discovered that you can buy "18650" 3.7V Li-ion cells (5800mah/per cell apparently) for really cheap here in Canada, plus they're quite small. Four of them wired in series can supply 14.8V... a good amount to give to a Wii portable, no? Wondering if any of you have done this or if it's a...
