Feature Request: decade counter, bcd decoder, another kind of OTA, magic eye tube

[xaez]

@pfalstad

Some suggestions to extend the "features" of circuitjs.

The possibility to create and save a separate options-file (e.g. for the offline ver.).

This should be embed into the next update: merging of schematic parts (at this time only possible in the online version).

With the usage of ringcounter models, some examples would be practical.

Some newer models: johnson-decade-counter (4017) bcd-decimal decoder (74154, CMOS:4028) another kind of OTA (CA3080)

What about some extension of other tube models (like magic eye etc.) );

thanks and regards TSt

Merging of schematics is possible in the offline version. Load circuit one, select all, copy, load circuit two, paste.

For a bcd decoder, use a regular 4-bit decoder but ignore the extra pins.

There's already a ring counter which looks a lot like the 4017. It's just missing the clock enable and carry out pin. Do you need those?

Hello Paul,

thanks for your informations, the hint (using the online ver. to merging circuit parts works, but I'm not everytime online)

about your 4017 question, here are two circuit-examples using this IC

I didn't see any attachment showing circuit examples using the 4017.

Here are the examples, note: also the CE (clk inhibit) is an important pin, eg for cascading the 4017 regards TSt
