its a bit simple, can certainly use some work but overall useful if you know what you're doing. would be useful if there was a way to insert an output like you can the other variables. such as an input field for time with the 555 timer. id also suggest showing the equations that are being used so that one can understand what is happening and why.

if the scaling improves, the rating will too. very bad graphic experience. fields are off screen & cut off. otherwise it does the calculations as advertised

It's like having a very hi-tech electronics text blank template. Gotta be like 90% of every/any formula you'll ever need! 👍💝 Radio Edit 09/20/24. Wow! Now I just wish I knew only even half, or even only a third of what it's all about! 🦮MOg🎙📻💖🎙🎹💖
