Here I’ll list useful circuit calculators and conversion resources for electronics.
555 Timer Calculator
Voltage Divider Calculator
Capacitor Value Converter
Resistor Color Code Calculator
(More to come…)
What Calculator Would You Like To See?
If there are any calculators or converters that you’d like to see here, let me know in the comments below.
I want to learn electronics I’m 69 years old and guess what you’re never too old to learn teach me
You’re never too old (or too young) for electronics!
A frequency to antenna length , quarter wave, half wave and full wave would be super handy for those of us who dabble in amateur radio.

Tengo 69 años y tengo mucho interés en aprender
Cómo funciona la electrónica muchas gracias
esta mucho bueno.
I’m 63 and am excited to learn as well.
77 here so you’re not alone.
I am also in the same age and trying to learn.
I want to learn electronics that’s all thank you
Great =)
I want to learn more about electronic, I am 86 yrs young and never to late to learn more. I think it is good to keep the old “grey cells” active, or, get them rejuvenated a little.
Great to hear, you’re definitely never too old!
It would be nice to see an LED Resistor (Par/Ser) calculator.
Thank you for your efforts
Thanks, I’ll add that soon!
I’ve been interested in electronics since I was a teenager. But was always afraid with all the components involved it would be far beyond my brain capacity. Right now I’m 51 I’m a carpenter iron worker mechanic I can plumb and wire a house including the breaker box I can fix HVAC systems. I recon I have enough room for some basic electronics at least!

I’m 85 and spent a lifetime in electronics, started dabbling at around age 10 and spent most of my working life in the field. Still dabbling and glad to have a really useful set of calculators which save time and effort. (I guess I’ve grown lazy!)
Thank you for your resource.
I proud of you mr.Bill. I am also 64 years old.
Great website and projects. Teachers of electronics may be interested in looking at our apps for teaching.
You are very geneous teacher of an electronics
yes. i want those circuits dymistified.
spent 30 years working in pcb fabrication and 15 years in Electronic Assembly. Learned a lot thru association with electronics in this 45 year period, but finding this website has taught me more about electronics in the past year, since my retirement, than I previously learned thru my jobs. Thank you for this wealth of knowledge. aT 71, I never tire of electronics.
Glad to hear =)
Hi – if you could please – I would like to an inductance calculator for rf coils – I recently dug up a tracking transmitter circuit from long ago and it calls for two ” air wound 1uH coil – doesn’t call diameter nor length nor turns – just 1uH. Other calculators want all this info – yet if a calculator could work it backward like plug in 1uH and the calculator spits out the rest ?? Thanks !!!
I liked all of the interest and friendly comments.
