Curve Tracer calibration partly accomplished

CALIBRATION PARTLY DONE

Calibration involves adjusting trimmer potentiometers to set various behaviors, as well as some testing of the limiters and fault detectors. 

The adjustments completed were:

  • 10V reference voltage set
  • triangle wave generator frequency set
  • step generator gain to 1V per step
  • high voltage range to 200V max
  • mid voltage range to 70V max
  • low voltage range to 35V max

The adjustments completed were:

  • 10V reference voltage set
  • triangle wave generator frequency set
  • step generator gain to 1V per step

The adjustments with issues were:

  • high voltage range to 200V max (erratic adjustment)
  • mid voltage range to 70V max (erratic adjustment)
  • low voltage range to 35V max (erratic adjustment)
Verifications were done for:
  • current limiting indicator operation
  • triangle output in sweep and DC modes
I am not happy with the quality of the contacts for the cable connectors, as I get lots of phantom behavior as I move the front board and attempt adjustments. That may settle down when the unit is all together and in its enclosure, but I will think about some way of improvement the connections.

Bizarre behavior detected in a Raspberry Pi Pico based design and partially understood

ORIENTATION OF THE PRODUCT CAN CAUSE THE PI TO FREEZE AT STARTUP This particular product with a Raspberry Pi Pico would not boot up when sitting flat on the table in its normal orientation, but if tilted or turned it would come right up. When I hooked up a USB serial connection to the debug header, it worked fine even flat on the table.  INVESTIGATION BY DESIGNER AS WELL AS ME I first assumed that I had introduced this problem in the product, but happened to describe it to the maker who was able to reproduce it reliably. I continued to try variations to determine whether it was pressure on a board or component that caused it. I also searched the web for any reports that might cause Pi Picos to fail to boot based on orientation, but found nothing.  The designer found signals introduced on a serial connection trace when sitting in the normal (failing) orientation but not injected when rotated or otherwise turned. Traces were routed from the UART0 on the Pico to a header, for use...

Incompetent coders - the frustration of using Vivado to build FPGA designs

IDIOT SOFTWARE MUST BE RESTARTED CONSTANTLY TO SEE INPUT FILE CHANGES When I update a source file, often Vivado is somehow working from a cached copy and never notices the changes. It is highly frustrating to fix an issue, rerun a Linter or Synthesis and get the same old errors. The only solution is to shut Vivado down and restart. I remember hitting this many times in past years as I worked with the toolchain, but it has changed from sporadic to nearly constant failure to see the changed timestamp. I can't be the only person running the toolchain under Windows, yet this kind of bumbling misperformance has been a feature for years.

Found correct mod for the Arduino Mega 2560 to avoid powering it from USB

USB HANDLING CIRCUITS IN THE MICROPROCESSOR REQUIRE USB VCC TO RUN The reason my first attempt failed, simply removing the poly (resettable) fuse, is that the fuse is between the USB connector and the microchip which needs the USB VCC connected. I had to reinstall the fuse.  BETTER CHANGE IS TO REMOVE A MOSFET THAT ROUTES POWER The Arduino uses a power mosfet and a comparator to decide when the external power is adequate to run the board, disconnecting the USB VCC from the board. It does leave that wire connected to the USB circuitry in the chip, however. With the transistor removed, the USB power never gets to the board so it is always powered by the external (1130) power. This means the board powers up and down with the main system, whether or not a USB cable is connected to anything else. When the board is powered up, the cable is active as a serial connection, exactly what I wanted to happen.  In the picture below, the green circle shows the reinstalled polyfuse. The red c...
