Hello, what transformer do you use for the power supply? I'm about to build that clock and I was thinking of winding my own transformer but if an off the shelf version can be used that's easier. Thank you. -------- Original message --------From: jörg <post...@gmail.com> Date: 04/03/2023 12:14 (GMT+00:00) To: neonixie-l <neonixie-l@googlegroups.com> Subject: Re: [neonixie-l] ScopeClock with teensy4.0 @Jon,yes, I will share the code. I have moved it to the VS Code IDE with PlatformIO. I do not like the Arduino IDE much. It should run on david's hardware, too.Do yo you have build the hardware already?On Friday, March 3, 2023 at 5:12:46 AM UTC+1 David Forbes wrote:I was able to change to a Teensy 4.1 with a 2 channel 12 bit SPI DAC in my latest version. I had to reduce the DAC rate by half. It looks just as good as the old version. Of course, the DAC I chise is already unobtanium.On Thu, Mar 2, 2023, 7:17 AM jörg <pos...@gmail.com> wrote:Hi, maybe a bit offtopic.I've put some effort in using the teensy4.x to run the scope clock based on david forbes one.The teensy3.6 based one is running on my own hardware for a while.But because of CPU shortage and the use of the teensy3.6 internal DAC's, I was curious to get the stuff up and running on the faster teensy 4.x CPU.In this approach I'm using a parallel driven 12 bit 4 channels DAC. The usage of a serial DAC was too slow and I did not get DMA up and running on teensy4.x.Anyway, this works and I like it.Video: https://youtu.be/HYwgyYnQUxw
