09:08 PM rue_mohr: L9110 can take 12V
09:15 PM rue_mohr: 800mA
09:15 PM rue_mohr: maybe at the same time, maybe not
09:15 PM rue_mohr: their not expensive
09:15 PM Tom_L: good thing if you're gonna test em that way
09:15 PM rue_mohr: its a chineese datasheet
09:15 PM rue_mohr: what can I do?
09:15 PM rue_mohr: anyone else going to be here for countdown?
09:21 PM Jak_o_Shadows: guys, the countdown was hours ago
09:27 PM rue_shop2: k, well you shoudl have said something
09:27 PM rue_shop2: I'm only 7:21 here
09:33 PM Jak_o_Shadows: Like, PM? Well, I'll be around for your count-down then
09:35 PM mrdata-: https://cdn.dopl3r.com//media/memes_files/when-your-jeep-is-just-as-upset-as-you-are-about-the-weather-1hoKj.jpg
09:35 PM mrdata-: it's 10:24 pm here
09:37 PM Jak_o_Shadows: ah, yeah, I'll easily be around
10:01 PM rue_mohr: hahh
10:33 PM rue_shop2: oh, theres the L293
11:02 PM rue_shop1: ok, I got 300 degrees in 194ms
11:02 PM Jak_o_Shadows: ooft
11:02 PM Jak_o_Shadows: wait, not temperature?
11:04 PM rue_shop1: hah
11:04 PM rue_shop1: no angle degrees
11:05 PM rue_shop1: so, thats the max slew rate of my servo
11:05 PM rue_shop1: next I need to do a freq sweep
11:06 PM rue_shop1: I dont know if I can just do it closed loop proportional
11:06 PM rue_shop1: idea
11:06 PM rue_shop1: what has a pulse width of 100ms at 50% duty
11:07 PM rue_shop1: 5hz
11:16 PM Jak_o_Shadows: Happy New Year?
11:18 PM Tom_L: yeah happy new year on the E coast
11:18 PM rue_shop1: HAPPY NEW YEAR
11:18 PM rue_shop1: where?
11:18 PM rue_shop1: ok I have to watch the clock more carefully
11:19 PM rue_shop1: ok, so, open loop, I have the following frequency response
11:19 PM rue_shop1: 5Hz 1.5V p-p
11:19 PM rue_shop1: 6Hz 1.1V p-p
11:19 PM rue_shop1: 7Hz .84V p-p
