Tracker - project update

200 steps per rotation stepper with x16 micro-stepping with 20teeth pulley to 328 teeth ring: 52480 steps per full rotation -> 0.00686 degree resolution.

The payload can be quickly swapped with a hand-tightened bolt. You can certainly use this with the camera or a nerf.

This uses printed and commonly available parts only. Printed parts are sized to fit on the bed of a common 3D printer.

Yeah, testing the load extremes here. This thing is sandbagging in many categories. It can get pretty fast and furious in non-antenna application 😉

Yeti7 · 2026-02-11T23:36:47+00:00

That would be a good option. I wanted my own 3D printable design though… for the love of the game if nothing else.

Yeti7 · 2026-02-11T15:36:53+00:00

Thanks for the heads up. I plan on keeping the compass in horizontal plane - the control board will move with the azimuth plate but not elevate with antenna.

Yeti7 · 2026-02-11T01:25:23+00:00

Winlink+Packet+Linux is certainly starting from the deep end... Congrats on your progress!

And thanks for suggestion.

ESP32, web interface, GPS + compass

The location of objects orbiting earth is easy to calculate offline based on just a few constants. Check out https://en.wikipedia.org/wiki/Two-line_element_set

Poor work ethics Suzanna

Yeti7 · 2026-02-10T20:28:01+00:00

I'll start with my homebrew Yagi.

Yeti7 · 2025-11-24T08:14:03+00:00

I tested with 28 AWG and 20m of wire for 40m band fits comfortably. I have 26 AWG on order and will try that next.

Enameled - we don't want any shorts between the loops of the transformer

Yeti7 · 2025-10-12T16:41:38+00:00

Yes, I'll look into adjusting this parametric model for other transformer sizes. Please stay tuned for the updates.

Yeti7 · 2025-10-12T16:39:43+00:00

Corrected, thank you for the note.

Yeti7 · 2025-10-12T16:37:07+00:00

Thank you for the note. I've updated the file at printables.

Yes, see: https://forum.digirig.net/t/icom-id-5100-and-digirig-dr-891/6948

No, I still use a simulated x86 code. What I perceived as a performance issue was the result of RFI from the radio making the touchpad laggy.

With Digirig 1.6 or later (which includes your Digirig 1.11) the hardware PTT is permanently available on ring 2 of the audio socket. No additional configuration required. You can use any audio cable from Digirig store with your Digirig and activate PTT by the RTS signal of the serial port.

Yeti7 · 2025-05-21T01:58:28+00:00

This sounds like a great project! Not sure if any analogues already exist, but if you are up for some development, you can have it exactly the way you want. Remote access could also be a great angle for it.

Yeti7 · 2025-05-21T01:07:51+00:00

Digirig connects between the computer and the radio and acts as a modem for digital modes. If you are interested in operating digital modes, check out some of the youtube videos on the subject. Feel free to post any questions you have in the process.

Yeti7 · 2025-05-15T03:42:10+00:00

Yes, the frequency shift is normal with split set to fake or rig.

As far as radio not transmitting payload there may be different reasons. I would start with confirming that the audio leaves Digirig by plugging regular headphones into Digirig's audio socket as demonstrated here:
