3mm between collar and edge of panel wouldn’t scare me off, personally. that isn’t much different compared to other modules even just in the picture you attached :slight_smile:

Pam’s encoder is definitely closer to the edge, Pole looks like it might be 3-4mm, and the jack nuts on my Intellijel 1U headphone module and knob skirts on my 1U Quadratt must be within 3mm of panel edge, too. no pressure either way from me to do 22hp, just thought I’d point out that it probably wouldn’t feel too tight once installed!

edit: plus, I personally think using blank panels to gain space would work for folks who want extra space, but the 1U world is full of tough combinations of hp so keeping things as compact as possible will likely help widen the appeal (if that matters).

Hey @bpcmusic it’s been a while since you made an appearance here. I’m sure I’m not the only one who’d love an update and for me personally my interest is in the TXo upgrade :slight_smile:

Hi. Apologies to all for being so quiet lately. Work has been whisking me out of town and out of the country constantly this year. It has been kinda bananas.

I’ve been chipping away at my final tasks in the cracks. All TXn and TXb are boxed and ready. Some % of the TXo have also been boxed. All remaining modules are assembled and awaiting Teensy and final testing. I have all of the Teensy on hand and was able to resume attaching headers to them today.

I’m home for the holidays so it shouldn’t be too much longer before they are all ready to ship and the store goes up. I’ll give you all notice well in advance. :slight_smile:

So does that mean that there are still some TXb left. I’m desperate for this as I have Ansbible and ER-301, but nothing to power the i2c connection to make it work with polyearthsea

#1017

I’ll purchase one of each please
Thanks for making cool stuff

#1018

There will be plenty TXb, I think (based on interest shown on the site). I made a bunch of them.

The TXo, TXo+, and TXi will go quickly. I think the TXn will as well - even though I made a bunch of them too.

I’m currently putting headers and daughterboards on the Teensy 3.6 processors for the TXo+ modules. It is a pretty slow process I’m finding as there are a lot of pins to solder and then to trim.

When putting on the daughterboard, I need to snip the headers so that they don’t touch and remove the “extra pin” that isn’t used (the one to the right of the daughterboard).

I’ll be notifying folks here a few days before the sale goes up and, as has been my practice, I’ll work to pick a time that is the least painful with some international considerations. :slight_smile:

Hey… where do you find those pin headers? Are the pins round?

Amazon/Ebay. They are listed as “precision headers” or “machined headers”. I always have to go on a hunt for them when I need volume - but they slimmed up the TX modules a bit to help the two-board layout fit in most cases.

#1021

Yeah OK - I have some machined headers that are round and they don’t want to work with the “square” female headers I have from Tayda so I’ve been wondering about other options. :slight_smile:

#1022

Stupid question but I couldn’t find the answer : is it possible to upgrade a TXo to TXo+ and if so what is involved, i.e. what do I need to get and what do I need to do (especially : is soldering involved) ?

Thanks again for all your work :metal:

Yes, me too.
I have two TXos, and Would like to have these up to spec with the TXo+

Thank you for help/advice!

Yes, I’ve read that page before but I’m still not sure at all of what needs to be done to perform the upgrade (I’m more of a software person than hardware person) :slight_smile:.

#1026

To perform the update, you need to remove the old Teensy from the back of the TXo and replace it by a “structure” (see photo) consisting of a Teensy 3.6 and a small PCB with just two or three SMD components soldered on it. If you DIY you also need to flash the Teensy firmware of course :slight_smile:

I think you can buy the teensy 3.6 and its “power board” from BPCMusic (soon) - already soldered and ready to be mounted on your TXO - or you can get the PCB from OShPark and the Teensy from anywhere you want and DIY.

I don’t know if some capacitors need to be changed on the main boards (C2 C3 C4, maybe ? 180p instead of 110 according to the BOM. I don’t know if it’s important, I built the 3.6 versions directly with 180p)

In case it helps, I’ve found a reference at Mouser but it’s quite expensive, the brand is called Samtec, they make machined pin headers male/male and female/male 07

Hi there - I’m late coming to the TELEX range, so not fully clear on all the options. I would really like to add a TELEXi to my TT, and keep my connection to Ansible. Looking at the gear that means I’d need a TXb right? many thanks :grinning:

#1029

Not necessarily. My Teletype supports three connections (Ansible, Just Friends and a Slashes board for W//) across my small case with just a ribbon cable with multiple headers. TXb could be useful for other things as well, ofc

I also have a very newbie question to ask, is it possible to use a Txi as well as an ansible in the same scene? I essentially want to use my ansible as 4 additional outputs while using the parameter knobs on the Txi to control aspects of those outputs.

#1032

Yes, this is possible. Teletype can communicate with several modules at once over I2C; the commands that aren’t relevant to a given module will just be ignored
