ZERO unroutes! (Also, there was an extra pin on the MCU, so I added a second LED. Can't let pins go to waste!) I still need to clean up the routing, do planes, and silkscreen, but the worst is over! Backing up.

Lots of progress! Down to about 35 un-routes. So close! Backing up.

Lots of progress on routing. The end is in sight! 156 Unroutes left and almost all the important lines are connected. Backing up.

I am laying out this PCB in the back seat of a truck on my way to Southern Utah. For some reason that feels hard-core. More layout progress. Backing up.

More progress. We're at around 200 unroutes and just about all the components have been placed. I am using pin-swapping to make the routing easier and cleaner.

Lots of progress. Less than 400 unroutes now. Looks like everything is going to fit! Thank goodness (but....... I can't say that for certain until I'm done I guess.) Backing up.

Tons of progress today! Still lots to do. (I started at about 1200 unroutes and now I am down to about 750). Backing up.

Solid progress on PCB layout (it's going to be pretty challenging!) Some changes to the solid model to reflect board outline changes.

Further updates to the PSDR2.5 Schematic, basically done. Time to start routing! Due to weirdness in the .PCB file, I am creating a new file and replacing the old, but I wanted to push it before I do that, as a backup.

Progress on updating the schematic for the PSDR2.5. This is mainly a backup.

This adds the final encoder board for the PSDR2.5, and includes much progress on the updates to the schematic and a little bit of work on the PCB layout.

Making changes to encoder board for new housing design, started integrating the new RF synth and mixers into the schematic.

Upload of my development on my work computer. This includes some efforts to get serial working for the GPS (I think) and maybe some experimental transmitting test stuff? Anyway, mostly included here for completeness, and because I will not be doing PSDR development on this machine anymore.

Initial transmit support. Internal microphone working. Capacitive touch sensors working. Currently touch TOUCH1 to transmit, waterfall changes color and shows the filtered output that should be transmitted (except that it's MUCH noisier than it looks, due, I think to DSP issues.)

Just backing up. PSDR2 is receiving well, image rejection is good. Gain pot settings work. Audio out works (to earphones only, the speaker fails pretty badly, not sure why, but that's hardware anyway)

Enclosure 3D files, Assembly Diagrams and Assembly Guide. Also so work on getting the firmware compatible with the PSDR2 hardware. Probably some junk as well. Lots of files.

PSDR2 Release. Schematic, layout, and gerbers complete. PSDR1 gerbers moved to Old folder (probably should just call it PSDR1...) Started (and almost finished) Encoder daughterboard.

Backing up. Routing is looking good. Just planes and silkscreen to go!

Backing up. PSDR2 has reached the point where it could be produced and would work; all lines are routed and there are no clearance issues. I am cleaning up the layout now, need to do some planes, silkscreen, then I am DONE.

Backing up. All components placed and only a few routes left. Cleanup, and other finishing details will happen next. Almost there....

Except for the microcontroller, component placement and routing is complete. Now it is time to start doing that.....

Backing up. Cleaned up component placement a lot. Made moats around circuit blocks so there is room for vias. I also like the idea of the blocks being separated, maybe even labeled. I'll do it if I have room. Need to redo almost all of the routing, then I'll be ready to move the MCU into place and start hooking it up! Lots of work to do, but it's coming along very nicely :D.

More progress on PSDR2. Schematic is basically complete (at least, all the components and blocks are in, though some connections between blocks and to the MCU are not in there yet.) Also started layout. Location sensitive components have been placed. It's going to be so cool!

Initial commit to GitHub.
...
Includes the Source (as an Eclipse project) and the Hardware files (including schematic, layout, gerbers, and bill of materials.)
The firmware is extremely incomplete. At this point the DDS chips work (with controlled phase relationship), the LCD (with fast-ish SPI, scrolling, and GFX, modified from Adafruit's library), the encoder knob, and LED work.
The ADC is capturing, but not in a usable way, but it's enough to feed the DSP code and see a nice pretty waterfall. Timers, interrupts, and DACs are not working yet.
