* CatButts ponders stitching up multiple vape batteries together and sticking them to the back of n90020:56
CatButts1000mAh each20:56
CatButtssupposedly20:56
CatButts3x20:57
CatButtsprobably needs a charging circuit tied to each battery20:57
biketoolit has been done before20:57
CatButtsand a fake sense resistor20:57
KotCzarnyjuz go with dual 1865020:58
KotCzarny*just20:58
biketoolthe old souble scud in a mugen caseback20:58
biketoolbut sand down the bottom of your batteries or it will flec the board and you will have to reball your modem in a reflow20:59
biketoolflex20:59
CatButtsbut I have vape batteries handy20:59
CatButtssure, they have the width of 3 regular batteries21:02
CatButtsbut hey, why not21:02
CatButtsfor shits and giggles21:03
CatButtsand maybe I can do something about my keyboard's pesky layout21:03
biketoolthey are great to power a pinecil, I use that for field soldering21:04
CatButts1000mAh vape bat packs?21:04
biketoolpine64 soldering iron, the cpu probably could be a attiny85 but they use a risc-v21:04
CatButtsalso, about my keypad, it has a shitty layout printed21:07
biketoolI got an 6x18650 usb-c pack which can do up to 12v, the pinecil can do up to 20, the barrel jack happens to fit the power of my asus laptop too21:07
biketoolyou have a US keypad?21:08
CatButtsno21:08
biketoolif you look on TMO they is a guy named maemish who has parts galore21:08
biketoolthere is21:08
CatButtsI am thinking scraping the keys21:09
CatButtsand leaving them blank21:09
biketoolI recall that being easy even when you dont want that to happen21:09
CatButtshaha, it is partially scraped21:10
CatButtsa little21:10
CatButtsalso, I haven't gotten around developing things for N900 beyond crt hello world21:11
biketoolit is fun but a little late :)21:11
CatButtsit's not late if it's for myself21:12
biketooltrue, and it is easy to dev for with the gui and all21:12
CatButtsI also have an android device, but eh21:12
biketoola little python and you are good to go21:12
CatButtsI have a java applet for drawing ported to it21:12
biketoolpinephone is the furture, and the future is pretty cheap21:12
CatButtsoh, oh21:13
CatButtsI found another interesting compiler21:13
CatButtsbesides TCC21:13
biketoolI have to figure out the i2c lora back I got21:13
CatButtshttp://pcc.ludd.ltu.se/ has this been tried on Maemo?21:13
biketoolI dont know21:13
biketoolhave to scour talk.maemo.org21:14
biketoolthere was a full bootable dev OS a few years back with all of the tools and compilers once the maemo cloud went away21:14
biketoolas in boot form a USB or CR21:14
CatButtsoh, I wonder one thing21:21
CatButtsif I could use the n900, and wires with alligator clips to charge individual vape battery cells21:22
CatButtsbut I'll lack battery's sense resistor21:23
biketoolI forget the requirement but just ohm-meter the resistor and make one with through hole components21:28
biketoolttyl21:28
CatButts110kohm bl-5j21:32
CatButtshaha23:16
CatButtsthe phone instantly shuts off with one vape battery23:17
CatButtsprobably trying to draw more current than the battery can dispense23:17
CatButtsduring boot23:17
CatButtsor maybe I messed up the sense resistor23:18
