DutchTronix ScopeClockx

Do you have an oscilloscope? Do you have an Arduino? Do you need a clock to impress your houseguests and/or fellow engineers? If you answered “YES” then you must build Jan’s Scope Clock Shield TODAY!
For super extra bonus points, combine it with a Pong Clock.


Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

  1. The scope-shot looks like a raster scan display. Is the Scope Clock Shield generating pixels in scanline order, or is it generating vectors and your digital scope is rasterizing it?

  2. The image is generated using vectors but there is a separate character generator which uses a small raster scan. The numbers on the dial are vector generated. The characters in the name field and the numeric field are generated with the raster scan.
    Each dot in the character generator actually occupies 3 pixels (“fat pixels”). This solution saves a lot of flash table space for the character generator; important since the Atmega168 AVR flash is completely full.

    All source code is available on http://www.dutchtronix.com/ScopeClock.htm.
