It may be possible to do this, yes. I believe that the TQFP parts (in Netzpfuscher's PCB) are basically a superset of the QFNs on the dev board, so that any pin selection that works for the dev board can also work for a TQFP based PCB.

Unfortunately the PCBs out in the wild (those from when Steve Ward built his, Netzpfuscher's and one that I have) are designed around a pinout that can't be replicated with a dev board, so there'll always be a need for a couple of different configs. None of this is particularly hard, it's just annoying as someone has to muck about changing stuff for every code release.

I reorganized the code and found a relatively good solution for the different boards. I split the code in a common code base and the board specific files. The common code is linked in the board specific folders. The _QFN projects are for the dev board and the _TQFP for the classic boards.

If someone gives me the pinout of the dev board version I merge it to the git. I only need the ".cydwr" file. Or clone the new repository and make a pull request.

common:
binary Binary files like the precompiled bootloader
ntshell Shell code
rtos FreeRTOS code
uart_ldr UART-Bootloader code
ud3core UD3 code

Here is what I have for the cydwr attached.  I also changed the clocks around as well.

Thanks,

Dan

There are a bunch of new features incoming. https://github.com/Netzpfuscher/UD3/tree/burst_mode

  • Ethernet support with a Wiznet W5500
  • Teslaterm with IP-Support
  • Teslaterm now has a MIDI-In. With a virtual MIDI-Port it is possible to send MIDI from every App you like
  • Teslaterm with support for a Korg nanoKONTROL2 controller
  • The UART is equipped with a protocol and transport layer for error detection and retransmission (https://github.com/min-protocol/min)
  • Burst mode interrupter

The Ethernet connects to the 8pin header on the UD3. I think Ethernet is a good choice. It is isolated, cheap and you don't need special Hardware. If you want to run a multi coil system, you can throw a switch between the coils and connect a fiber Ethernet to the computer. If I have the Firmware in a good state, I upload a release in binary form. I think it is much easier to flash a binary for someone who is no programmer ^^

We hit the 2m ^^

I've made several bugfixes. Ethernet is working, Teslaterm is more stable.

Actually I'm working on the duty cycle limiter for the MIDI mode. My first proof of concept works relatively good. There are no more big current spikes if a very high MIDI-Note is playing.

I've added a new synthesizer in the UD3. The new synthesizer "emulates" the famous SID chip. The UD3 interprets the music on a register level. The noise synthesis of the SID makes a very nice drum effects.

Very neat  :)
There was a short discussion on 4hv a few years ago on tricks to enhance TC sounds.

Cool, new stuff to play with :)
Unfortunately I haven't had time to do much work on coiling recently, but I will be giving your new code a go when I get a chance. I'll also be in NZ again at the end of the year, so will have my large coil to play with too (I have a 75% finished UD3 board to install into it). On that note, Uspring - I'll be having another go at the toroid current measurements I promised and failed to do in April, this time I will have a lot more time to spare and hopefully won't injure my back trying to lift the coil down out of storage like I did in April!

Great progress on the UD3 Netzpfuscher!

I will set it up as a goal for this winter to get a working UD3 with your software :)

One warning. The newest GIT-Version of the Dev-Board UD3 software has a messy pinout. I need to correct this before I merge it in the master branch. I use the dev-board for ethernet debugging so it is a little bit hackish. In general there is heavy work in progress ^^

I also work on a new PCB revision in Kicad with integrated Ethernet. Ethernet works so great and doesn't need special Hardware. I think it is better to go away from the expensive Altium ^^


Thanks to malte0811 the Teslaterm is growing. He added a scripting feature to automate the coil for show use.
In general the UD3 ist still fully functional with a normal VT100 Terminal.

I've made Teslaterm and the UD3 more user friendly with a settings form. I found some small bugs in Teslaterm and the UD3 and fixed these. The newest files are in the master branches:

Thanks! I'm about to order some boards to upgrade my big coil (in NZ) to a UD3 to use when I'm there over Xmas. Will take some pics/video and also some topload current waveforms to share.

Hello everybody and thanks already for this amazing work!
It has been >10y that I messed with tesla stuff, but somehow it's in my head again.  ::)
Looking at the different UD iterations using FPGAs seems obvious to me. Combined with the simplicity of this dev board... great!

I'm preparing to order the pcbs and was wondering if the plans for the Psoc5-Power found in the pcb pack are still the most recent/recommended versions for this driver?
Should I consider to add or change something?

Greetings from Cologne,
Flo

Apparently there have been updates to the pinout that I have not incorporated into Psoc5-power yet, so you might want to hold off.  You don't need the board if you want to breadboard it.

I could update it if I get an updated pin list.  I haven't looked at the latest PsoC creator project lately to see what the new assignments are.  I think there is support for Ethernet now.

It should be possible to go back to the old pinout. I primarily changed it to make a simple connector cable to the W5500 board on my desk ^^
Perhaps I add a non development version with the dev kit to the UD3 project.

I've added a new experimental feature. A fuse emulation.

You set the maximum continuous current and the 10s limit from the breaker curve. The UD3 tries to limit the duty cycle to keep the fuse under 60% of the trip point. The gauge on the lowest right is the fuse (100% fuse tripped). The gauge in top of the "fuse" is the duty cycle limiter (higher is more limited).

If the controller can not keep the current low enough and the fuse reaches the 100% the UD3 shuts the coil down.

I think there is a lot to improve, but you can see what I'm trying to do.

Very nice feature, I can really see that come in handy for shows where it would be good not to have a trip or any kind. Did you try it out with sparks and most interesting heavy ground strikes?

No, this is the next step. The test in the video is only a static load test with a bunch of scrap metal in the primary.

We have made some full power runs. Input power is around 10-18kW from 3 phase mains 580V on the bus.



We had some problems with the ESP32 interface, but I'm working on a new one. Based on node.js and can be run on every computer/raspberry/orange pi/ etc...

Just watched the videos - nice work!

Unfortunately haven't had time to do much work on my coil(s) recently, but when I do I'll have a play with all the new features you've added.
