Kevinli, I still see the pictures. Is anyone else having trouble viewing them?

Darksyder, if I could start from scratch, I'd use a Pi4. I'll eventually need to add some bits to the walkthrough for people who are using the Pi4. I don't reckon it would change too much about the build, but there may be subtle differences to connections. Let me know, anybody, what the difference w...

Hi, here’s the balancing board I used! https://www.ebay.com/itm/2S-3S-4S-Li-ion-Lithium-18650-Battery-Packs-Charger-Module-Balance-Board-100mA/122727035587?_trkparms=aid%3D111001%26algo%3DREC.SEED%26ao%3D1%26asc%3D20160908105057%26meid%3Dc2b16bdacddb4b1f93f72be7f79dc140%26pid%3D100675%26rk%3D6%26rkt...

Thanks again, AntFJ! I did indeed have in mind adapting his general idea to my hardware set-up using custom code. One of these days! Your help is greatly appreciated.

The resistors are why I thought I could run it the way I had it before. To be lazy and paste from my Page 1 description: “you want to be able to monitor how much life is left in your battery so it doesn’t die while you’re playing! If you use a 3.7V battery setup, there are a few possibilities for cr...

AntFJ, thank you for clarifying that. Is this updated diagram what you meant? I have moved the ground wire too, just to keep things consistent.

LabreaReloc, thank you for checking in. I’ve been thinking about this project nonstop. You’d think that this would be the perfect time, right? And yet due to a number of logistical factors involving being furloughed from my main job and having to pick up a freelance gig, and having to constantly att...

Djobbydjobba, so sorry for the delay -- I had notifications set to "On" but I don't think I was receiving them, so I didn't realize anyone had replied to me! Thank you for pointing out that the diagram was missing a ground wire! This was a complete oversight, and I can't remember what my headspace w...

Darksyder, you’re so kind to check in — I really appreciate it! I haven’t touched the project in awhile I’m afraid, because we bought a house and moved a couple months ago, and everything has been nuts since then trying to fix the house. But again you’ve spurred me to get back into it again. I would...

I was hoping y’all could take a look at my diagram and see if it looks ok or if anything is out of place. Thanks so much! https://i.imgur.com/T7RbChx.png EDIT 5/4/20: djobbydjobba kindly pointed out the diagram was previously missing the ground wire to the Pi pin 6! I have replaced the original diag...
