Re: DIY Mutable Unsuccessful Builds

@aseaman

Are these AC or DC measurements?

Do you have an oscilloscope to measure signals with?

Check you have the correct value components in place especially round the op amps

Re: DIY Mutable Unsuccessful Builds

Some of the jack sockets are normalled to the normalisation probe so plugging in cables will change the measured resistance.

Re: DIY Mutable Unsuccessful Builds

The trick to desoldering the capacitors is to put more solder on their contacts so it forms a bulge. Then apply the soldering iron at the side of the capacitor so that it heats both bulges simultaneously but not the body of the capacitor. Push the capacitor to one side away from both pads whilst the...

Re: DIY Mutable Unsuccessful Builds

There’s no reason why C13 should get hot unless it’s damaged.

The state of the LEDs will probably be random until the microcontroller is programmed.

There is probably as short(s) somewhere still on the board.

Re: Synthi options

I don’t think Behringer will have a Ghielmetti matrix in their VCSX, EMS never used one from them and the engineering tolerances aren’t that tight.

The issue will be economy of scale.

Re: Synthi options

How about an alternative design to the the expensive matrix?

I would imagine Behringer are considering this.

If you replace IC3 are you getting the correct voltages across C3 and C22?

[/quote] thanks for looking at the pictures. In the meantime I tried to take some higher res pictures with my reflex camera, but taking macro pictures of a pcb is quite a difficult task I realize... I'll give it another try tomorrow. Also, I reflowed the pins on IC5. makes no difference. I tried to ...

Re: DIY Mutable Unsuccessful Builds

Something is getting hot and has thermal shutdown protection or is expanding and breaking a connection.

Re: DIY Mutable Unsuccessful Builds

I think the buzzing is the DC-DC converter trying to supply too much current. Can you measure how much current is being drawn from the supply on each rail?

It's difficult to tell from your photos, because of their resolution, what problems there may be.

Some of the pins of IC5 don’t look soldered.

Re: DIY Mutable Unsuccessful Builds

I just finished assembling beehive (Plaits). It's my second mutable module after EARS and I was really looking forward to start the flashing procedure. Unfortunately, the module itself makes a constant high buzzing noise when connecting it to power. It is clearly audible. It's hard to localize, but...

R40 and R41 are 'Do Not Place' so do not bridge pads or place any components there.

Re: DIY Mutable Unsuccessful Builds

I sometimes find my STLinkV2 doesn't connect to the Utility program.

The update option in Utility gives you the option of connecting.

Re: DIY Mutable Unsuccessful Builds

If you didn’t change the voltage setting on the interface then you could have damaged the microcontroller.

Re: DIY Mutable Unsuccessful Builds

Heyo guys quick question. I built a clouds like a year ago and it didn’t function correctly even tho the soldering was pretty darn perfect with no bridges. However I was a noob at programming and I programmed the clouds with a 5V FTDI instead of a 3.3v one. Did that fuck up my processor? Because ev...
