Electronics calculators, an adaptable formula solver, interactive circuit tools, and clear engineering references in one focused workspace.
Live tools
These quick calculators and interactive checks sit beside the full electronics bench and formula lab, giving visitors useful results without digging through a datasheet.
Calculator bench
Ohm's law, resistor networks, dividers, RLC impedance, filters, timing, LEDs, 555 circuits, op-amps, regulators, switching converters, MOSFET/BJT switches, dB levels, I2C pull-ups, debounce timing, batteries, ADC/PWM, wire and PCB trace estimates, reactance, colour codes, and supply ripple.
Electronics formula lab
Paste or type equations, choose the unknown, enter known values with engineering units, and check the result against the original formula.
See how the output changes when the next circuit draws current from the divider node.
Move the time point and watch how resistance and capacitance shape the capacitor voltage.
Compare ideal op-amp output with what a single-supply circuit can actually produce.
Why tools
The tools here are built for the work that comes up repeatedly: choosing parts, sanity-checking values, explaining trade-offs, and keeping engineering decisions visible.
Six focused tools for LEDs, Ohm's law, battery runtime, loaded dividers, RC timing, and op-amp rail limits.
Twenty-one calculator modules covering components, circuits, power, signals, interfaces, and practical limits.
Enter a custom equation, choose the unknown, assign engineering units, and inspect the rearranged working.
Formula notes, sanity checks, worked examples, and links to relevant Lab Notes accompany the calculations.
Bench coverage
Ohm's law, resistor networks, loaded dividers, colour codes, reactance, and component values.
RLC impedance, passive filters, op-amp gain and limits, RC timing, 555 circuits, and dB levels.
Regulator heat, supply ripple, switching converters, LED strings, and MOSFET or BJT switching.
ADC and PWM scaling, battery runtime, wire and PCB trace estimates, I2C pull-ups, and debounce timing.
Need a tool?
If a repeated calculation is slowing down a project, Albion can turn it into a small browser tool, script, dashboard, or internal reference.
