The parts are pretty small to solder but it was in fact my first SMD project after a lot of through hole and while it needed some trouble shooting it worked and I was pretty proud when I finished it.

If you are hesitant I think Music Thing’s SimpleEQ is considered as a great first SMD project (and it is useful too in delay feedback line for example). Also I find the NLC projects nice to work on - more but bigger parts compared to the TX.

I would have never expected this to happen, but only a few projects later I am now at a point that I prefer SMD over through hole for convenience…

hi, i’m about to build my TXi and TXo. just got a pcb+panel from this forum.
want to ask does anybody has done the TXo+ upgrade? how difficult is the upgrade? does it stable? does the improvement feature worth the upgrade, or most of you doing fine without the upgrade?
i’m still considering if i should do the upgrade or not…
any opinions/comments are welcome.
thanks in advance :pray:t4:

Where do people get panels and pcb’s from? Is it just a matter of lucking out with the trade ads?

#1397

upgrade is by no means mandatory. if you use the txo as an oscillator frequently, the upgrade gets you more waveforms, a higher sampling rate, and less aliasing. it is pretty easy to put together and a pop in replacement for the old teensy. you really don’t need to change the few parts on the tx that i started doing differently - the have only a slight effect bringing in a teensy teensy more high end.

Seem to have gotten my TXo (bought from @bpcmusic in the last batch in Jan 2019) into a bit of an odd state, where using envelope gate ops (TO.ENV ch gate) causes an envelope only after releasing the gate. That is, I have only TT and TXo connected via I2C, and immediately after power-on I can run the following, either with or without doing TO.CV.INIT 1 first.

TO.CV 1 V 5
TO.ENV.ACT 1 1

In live mode I then run TO.ENV 1 1 and the envelope does not open, but after I run TO.ENV 1 0 it pulses, as if I had run TO.ENV.TRIG 1 (which still behaves normally). This was working as expected a few days ago, with TO.ENV 1 1 opening the envelope and TO.ENV 1 0 closing it.

Teletype is on the 3.1.0 release firmware. I have possibly been sending TXo a bunch of weird I2C messages during development of I2C leader mode for Ansible. Reckon I’ll attempt to reflash the TXo firmware next, but found it very curious that I could get behavior like this that is now persisting across power cycles.

This is just a heads up on a weird problem that I found with a home built TXi (actually built by Rob Spencer’s Southside Synthesiser Repair in Glasgow). With no jumpers connected the module seemed to be reading the jumpers as if they were all set to 1 (we discovered this by using the debug mode with the teensy plugged into USB). This meant that the module wasn’t responding to anything from the TT over the I2c bus using the usual 1-4 numbering. Looking at the schematic it looks like the input pins for the jumpers are floating so I wonder if that’s the problem? Could this be something to do with the particular components that we bought?

In any case we solved the problem by hard coding the cfg variable to be zero in the code in the setup function.

Hope this might be useful if anyone else is having a similar problem. Although I would also be interested to know why this issue occurred for us but doesn’t seem to have been reported elsewhere.

Hey @SimonKirby, it’s me Rob. Decided on @GoatFarmer :slight_smile:

I think you’ve persuaded me to enter the world of Teletype :slight_smile:

I do have a question to the forum… What’s the accepted norm for building these? I’m happy to do a very limited run, but don’t want to go against the grain :slight_smile:

You’ll want to ping @bpcmusic but his licenses do allow commercial use. Cc-by-sa 4.0 on the hardware.

Doesn’t look like a can message @bpcmusic directly at the moment being such a noob :slight_smile: Maybe he’ll reply here?

No worries at all. I used to run a thing called GMSN! which I closed down for exactly the same reason :slight_smile:

Thought I would check what the rules were first :slight_smile:

#1410

Behavior is still the same after this, TO.ENV.TRIG 1 works but TO.ENV 1 1 doesn’t open the envelope. I also tried a TO.CV.RESET 1 in case maybe the software was confused about the current CV value when calculating the envelope samples or something? No effect. I’m left wondering if this is possibly a hardware issue or something, though all the CV outputs seem to work fine otherwise, and measure fine on a multimeter, very odd. Has anyone encountered something like this? This is actually a TXo+ so it’s using a Teensy 3.6.

#1411

@csboling - weird. should work. i’m on the road this week; i’ll post a full example script when i get back to LA. doubt it is hardware…

Are there any plans for more production of these units? Thanks!

#1414

I don’t know about the Telexb, but there are plans for TXi and TXo units to be available on pusherman’s website in the coming weeks.

It also appears as if there are telexb kits available currently on Pusherman as well:

I will have to keep an eye on that. Specifically looking for a TXb that is already assembled.

Are there instructions on assembling TXb? I couldn’t find anything on github, but i could’ve been looking at the wrong thing.

#1416

Check out the BOM and instructions

I believe this is a different layout, but parts and materials would be the same. I’m actually guessing that if you don’t want to build it, there might be folks around here that would be willing to help.

That is a good point… anyone want to make a TXb for me?? Name your price! :grinning:

To be honest, if my current circumstances allowed, I would do it for you! But I actually wonder if it’s worth creating a new thread, probably in the teaser section for people to buy DIY services from each other. Could be a nice way for the community to continue to support each other. Who would we comment to to get that going?
