01:20 AM anonnumberanon: polprog, i found my solar cell this is what I have : https://www.velleman.eu/products/view/?id=438010
01:25 AM polprog: hmm, single one
01:25 AM polprog: should be good with that boost converter you posted, if it really can give 200mA
01:25 AM anonnumberanon: yes
01:25 AM anonnumberanon: since microcontrollers take very little current the only real draw would be the screen
01:26 AM anonnumberanon: lol
01:26 AM anonnumberanon: no man i like the stmf103
01:27 AM anonnumberanon: i want to learn it through a not too unoriginal project like a weather station
01:29 AM anonnumberanon: 120 milliamps for this apparently, and it even seems overkill for what I want (and definitely too expensive): https://www.amazon.com/Elegoo-EL-SM-004-Inches-Technical-Arduino/dp/B01EUVJYME/ref=sr_1_4?keywords=arduino+TFT&qid=1552116148&s=gateway&sr=8-4
01:30 AM rue_mohr: uh, you going to put it to sleep?
01:31 AM anonnumberanon: That would be neat
01:32 AM anonnumberanon: if you mean sleep mode for low current
01:32 AM anonnumberanon: I'm getting up to speed with libs and the way to code it right now
01:53 AM polprog: if its supposed to take little current you need to keep it in sleep mode as long as possible. no busy loops
01:53 AM * polprog sees a beautiful state machine brewing
02:08 AM anonnumberanon: at which point would you use a state machine?
02:15 AM anonnumberanon: 1134 pages
02:15 AM anonnumberanon: sigh
02:15 AM anonnumberanon: the reference manual for stm32f10x
02:39 AM anonnumberanon: how many bits is the stmega328 ADC?
02:42 AM rue_mohr: 10
02:42 AM rue_mohr: its all 10
02:44 AM anonnumberanon: ah

11:36 AM veverak: well
11:36 AM veverak: and here I thought
11:37 AM veverak: I won't put a ton of electronics into the ship
04:08 PM veverak: so
04:08 PM veverak: water proof connectors
04:08 PM veverak: 2.54 pin header style
04:08 PM veverak: any tips about how to do it?
04:08 PM veverak: (RC Ship)
04:10 PM deshipu: just cover them with grease?
04:10 PM veverak: hmm
04:44 PM rue_mohr: deox
04:46 PM veverak: deox?
05:09 PM rue_mohr: yea
05:10 PM rue_mohr: https://www.gescan.com/products/fittings/ilsco-de-ox-4oz-16470
05:11 PM veverak: interesting, thanks
08:05 PM justan0theruser is now known as justanotheruser
09:35 PM rue_shop1: today I made a 0.2"x0.3" 7 segment display, with charlieplexed segments, controled over 9600 baud serial by a tiny13
09:35 PM rue_shop1: hmm
