[13:59:18] <averowsky> I bought XL4015 to reduce voltage from 18 to 5V. I've connected + and - to IN pins in XL4015 and no matter how I adjust voltage with 2 potentiometer I get 18V on output
[13:59:34] <averowsky> Do I miss something
[13:59:35] <averowsky> ?
[14:02:08] <LeoNerd> It's a buck regulator
[14:02:10] <inkjetunito> yes :D
[14:02:16] <LeoNerd> Those usually have minimum load current requirements
[14:02:21] <LeoNerd> What are you loading it with?
[14:02:37] <LeoNerd> The way a buck works it can't really do its thing with zero load
[14:14:32] <averowsky> LeoNerd: Acha, ok I didnt know that :)
[14:15:21] <averowsky> thanks
[14:43:17] <Casper> A proprelly made buck should be able to operate at zero load
[14:43:24] <Casper> ... lots ain't well made..
[14:56:27] <averowsky> Casper: this one was very cheap
[15:36:34] <Mr_Sheesh> Adding an LED should be doable to keep it at minimum load maybe, tho?
[15:45:52] <MokoLokoToko> if I drop my library into /usr/lib/avr/include, will I still need to pass it explicitly to the linker ?
[15:46:21] <MokoLokoToko> or does the linker scan through all the libs in that folder to find what it needs anyways ?
[16:13:43] <averowsky> guys i connected XL4015 to stepper motor driver and and regulation doesnt work ?
[17:30:36] <Lambda_Aurigae> MokoLokoToko, no, it won't work that way.
[21:58:48] <ferdna> on a diy scanner can you use zoom(not digital) on your lens?
[21:58:56] <ferdna> diy 3d scanner
[21:59:00] <ferdna> 3d laser scanner
