TX Update (Panels and General Progress)
Just got a test set of panels from Lasergist and switched out for knurled nuts on the jacks:
- everything fit perfectly
- weight of the panel is fantastic - really make the modules feel done now that i've taken off the 3D printed ones
- their coloring is a little more shiny and metallic colored than the teletype (LED lighting and my fleshy face is causing the champaign tint of the photo - to the eye they look more steely grey)
- one panel (out of 15 total) had a slight mar on its face
- upper right corner of each panel has some extra material and is a little less than square (where the final cut of the laser is i guess); need to get a better tool to clean it up if i go this direction
- lettering isn't exact with the TT - but still looks pretty good (same font)
their price is the lowest cost option i have sourced for these things that still gives a nice metal 2mm panel (flush with the TT). I've made some panels with Front Panel Express before - they look AMAZING, but cost $$$$$$$. unless i can find a similarly priced option for a small run (thinking approx. 120 divided) that gets a color more like the TT, i think this will be the route that I go for the panels.
GENERAL PROGRESS REPORT:
i've already started bulk purchasing some components (knobs, jacks, passives, etc.). still have a couple TT firmware gotchas to resolve and want to do a "production" build test where I try to make a bunch of boards at once using my manual pick-and-place tool and reflow oven to see how many i feel that i can commit to making.
but, in reality, this is more or less the finish line. with a lot of help from others (especially @Galapagoose back in the circuit design and layout phase) they are"done" in that: they work, they integrate with the TT, they cover all the basic TT functionality + add some new cool stuff, i've assembled a bunch of them with a 100% success rate and consistent function, firmware for the teensy is stable, and mods to the TT framework are pretty straightforward (save a last couple of things i want to see done).
once i've resolved the two TT issues (adding timeouts for calling non-existent expander ports and problems reading from the input expanders on the metronome interrupt), i think i'll open up a new thread and start seeing who wants to get these babies. i'll also post everything up to my github site so that those who are more adventurous can make their own.
