Re: About Capacitors (in Mutable Instruments builds)

btw.. if the BOM states >=16V for a cap, can i savely use a 50V cap with the same value or should i stick to the >= value as close as possible? It should be fine. I wouldn't go *way* past the suggested rating, to like a 200V cap. Do make sure your substituted cap will physically fit where you want ...

Re: About Capacitors (in Mutable Instruments builds)

Can i in general replace electrolytic ones with ceramic (ignoring cost)? Usually, maybe not always. Ceramic caps and electrolytic caps have different disadvantages. The electrolytics are polarized and usually have high ESR; ceramics are better on those points. High-value ceramic caps, depending on ...

About Capacitors (in Mutable Instruments builds)

I am an electronics noob, so i need some help by the pros here please. I recently built a MI Stages and saw that emilie entirely used 22uF ceramic caps, while on older builds she used electrolyic ones for >10uF. Question1: can i use like 1206 10uF ceramic caps like https://www.mouser.at/access/?pn=8...

Re: DIY Mutable Unsuccessful Builds

Built Clouds DIY - all 3.3V pins read correctly for power, the -10 reference is also accurate. Was able to successfully flash the clouds firmware to the device. Calibrated at 1V and 3V to note/CV and the LEDs all behaved as the manual indicated. When powering up, the unit lights up the 4 LEDs red f...

Re: DIY Mutable Unsuccessful Builds

Good news! Sounds like the other one has a problem as well! :-) Yes. I found out when i link 2 Stages and create a 12 step sequencer and have the "jumpy channel 5" module on the right the jump does not "bleed" through to the first output of the left module. the MCU seems to send the correct voltage...

Re: DIY Mutable Unsuccessful Builds

You need the dac to be calibrated first, before calibrating the adc. (Follow the order in the notes - the output for calibrating the adc relies on accurate dac calibration) Good luck sorting it out - I’ve seen quite a few people have had similar issues with the 0603 build.... Alright thanks. Here i...

Re: DIY Mutable Unsuccessful Builds

I’ve seen lots of reports of people having placed the wrong passives in the lower area of the board as I dont think anyone has found eagle files and the labelling on the board isnt straight-forward (apparently). Maybe look there ? (Triple checking against the MI files). No idea if this is the issue...

Re: DIY Mutable Unsuccessful Builds

Hi, new here. I recently finished 2 MI Stages with the 0603 conversion from Pusherman. Both modules are not calibrateable because their outputs drift extremely and do not stop to drift even after 30 minutes (voltage drift is around 100-500mV up and down constantly) On top of all output 5 on both mod...
