04:26 AM Jak_o_Ombroj: my tap set arrived from china!
04:26 AM Jak_o_Ombroj: M3, m4, m5, m6
06:57 AM Kake_Fisk: I'm planning on combining gyro and accelerometer readings using a complementary filter. Does it make sense to use a lowpass filter on the accelerometer first?
06:58 AM Jak_o_Ombroj: depends on how noisy your accelerometer is?
06:59 AM Jak_o_Ombroj: Like, if you can sample that faster than the rest of the system needs?
06:59 AM Jak_o_Ombroj: and like, do you care about missing spikes?
07:00 AM Kake_Fisk: I see, thanks for the input :)
07:11 AM Jak_o_Ombroj: I'd say model it, but tbh, I only have the vaguest idea of how to do that
07:11 AM Jak_o_Ombroj: and even less idea of how to do it without simulink

08:56 AM Kake__: In many PID implementations in C++, I see that they have the delta time as a parameter to the controller. I assumed you had to have a dynamic time here using timing.
11:02 AM Moistmelon is now known as Wetmelon
01:28 PM hasioehrchen: Hoi
02:24 PM justan0theruser is now known as justanotheruser
02:39 PM katsumi: moin
02:48 PM katsumi is now known as simion
08:45 PM Jak_o_Ombroj: Kake__ is gone, but i tend to think that that's not really the case. Static time, and just hope it repeats at the right rate
