They are in stock @modular addict! Tot mime There as well after mailing for weeks with Doboz without a reply.

I’m kinda new to filling up a mouser cart in that a lot of those parts are “currently not available”. I was wondering if someone has a recent project on mouser (or Farnell)?
I’d be truly greatful <3

Hello,

I have a problem in my tsnm!

On every out I have a constant voltage around - 9.25 to - 9.55!

All other shows/works great, I can go to any programs
and the touch plates work too I think (the LED's light up)!

I have search really hard to find bad contacts but can't find any one!


Any ideas were I have my mistake....?


Thanks to you guy's

Great module!

Just finished this a couple weeks ago. After playing with it for a while I have to say it’s its a really worthwhile module. It works well and provides a lot of musical options.

ARP mode with hold is really great.

I had a similar problem. Did you solder all of the pins on the Teensy. There are two parallel rows, and one pin that is on the end at a right angle to the bottom row. I missed this pin and things worked but the pads didn’t work.

make sure the diodes are oriented correctly. i was getting high voltages on my outputs because one was facing the wrong way. i had assumed they were both oriented in the same direction.

Shellfritsch you are the man! I have one diode in wrong position!

Now the outputs run better ;-) gate work great....
But on the cv out I have only one Voltage.....

I think the opa171 have a problem


Thanks to all of you!!!

So tiny

Post by GrimmWobble » Sun Nov 18, 2018 1:52 pm

Hey all,

I think I have all the components in to start building (even a hot air thingie) but I’m doubting the very very tiny parts.
I have 0603 parts and I was wondering if that is the correct size for this build because the pads seem way bigger.

I’m just scared to start....please sooth me

Missing 1 component

Post by GrimmWobble » Tue Nov 27, 2018 1:47 am

Dear all,

I’m nearly done with the SMD parts but I’m missing the 1206 10u Cap
It seems to be out of stock everywhere and I was wondering if there are good alternatives for this component?

Depends where you usually buy your components. The package size is important, but capacitance and voltage rating not so much. The voltage regulator (ADP150) datasheet suggest 1uF cap for output, so I think anything from 1uF should work. Also as it is a 3.3V regulator, a cap with DC voltage rating 10V or 16V or bigger, would work fine. Hope it helps.

P.S. Where did you buy the pcb and panel?

Luckily I found a replacement on Farrell that arrives today :)
So I guess I’ll be doing some more soldering tonight yay!

Got it on Modular Addict a while back. Tried to get in touch with Doboz himself but never got a reply on my question if he could sell me one.

Can someone tell me if this is normal behaviour:

In Arp mode, with hold off (so H! is not visible)
I hold a pad and turn the encoder to change the pad note, but the display does not update the note name - unless I release the pad and press it again.

Same with the transpose pads, but they never show any visual feedback...

Morning all!

I just finished building my TSNM and everything seems to be working.
I have a question though, how does one start playing a sequence?

I figured out how to set the sequence or record the steps but the clock in of the varigate doesn’t trigger anything.
Do I need to do something more to get it to work or do I start trouble shooting my build?

Thanks all

Yes I did but it seems I’m either missing something or I made some mistakes during the build.
I must say, yesterday was late and perhaps when trying tonight I’ll be more lucky.

After you have input your sequence by pushing the pads, you push the encoder once to get back to the sequence menu. Then you start the sequence by inputting a clock to the c-input. Thats how it works for me

Yeah, I figured out that it should work like that.
Tried different clocks (varigate 4+, Dixie II+ in lfo mode, ears and a clock from er-301) as well as input but no luck.

So here’s what I do.
Hold down de encoder for 1 second, set to “se” press again and select s• and then tap in the sequence. Press the the encoder again to back out to s• and then nothing happens :(

Hopefully you’ll price me wrong and I’m just missing a step. I’m glad I’m finished this module but hope I don’t have to start troubleshooting...

Checked the 100k (r25) and 1m (r26) resistors and they seem to be ok.
Not sure how to check the transistor on Q1 but what I’m not getting “beep” when I check the right leg with the center one. Left leg does do something however I can’t say with certainty that it’s reading the way it should.

Other then that I think my touch thingy might also be faulty :(was

Alrighty, ordered a new transistor and a (blue) mpr121.
Hopefully that’ll fix it.

Troubleshooting a build isn’t fun... then I get reminded how little I know about electronics:/

I accidently hit the TSNM3U with +12V on the +5V and it smelled like it didn't like it :doh: It was on like 5 seconds.

After fixing the 5V problem (and hitting myself hard) I tried powering it up again, and it booted but started smelling again. It was on for about 3 seconds.

So, my question is, how do I proceed from here? I could just power it on and either be fine or have it burn out completely. Byt I'd rather not burn something hard to replace, that could have been avoided by replacing something easy to replace.

From visual inspection everything looks fine, but I might be missing something, cause I don't know what to look for...

Suggestions?

EDIT: On closer inspection IC7 (voltage regulator) seems to have taken a hit), I'm gonna replace that first.

logical that this part blew with wrong voltage - hopefully replacing it does the trick!

Hi
from what i read the diodes on the pcb are correctly placed (see image below) but gates and triggers are not working.
