linNet
The Software for symbolic Analysis of linear Electronic Circuits
linNet is an application to compute the transfer function of linear, electronic circuits. The computation is done symbolically, not numerically, and the result is a formula rather than a number or a series of such. The found formula is the Laplace transform of the dependencies of the voltages and currents in the circuit on the input voltages and currents. A linear electronic circuit is a combination of the supported basic devices; these are resistor, conductance, capacitor, inductivity... -

octelec - Electronics calculations
Electronics calculations in GNU Octave
The "electronics" package for GNU Octave provides functions for electronics calculations. Select resistor or capacitor values from E3 to E192 series, convert two-port parameter sets, calculate operational characteristics (voltage gain, current gain, input impedance, output impedance) for two-port circuits connected to generator and load impedance, convert ratio to dB and vice versa, calculate parallel impedances, and round values to a number of significant leading digits. -

ArdWeighno
Ultra simple way to connect a load cell to an Arduino.
A load cell bridge can be driven by two Arduino Nano outputs configured as an H bridge. An AC coupled op-amp amplifier is used to amplify the signal and synchronous detection used to measure the signal. Timer 2 is used to drive the bridge and timer 0 is used to trigger the analog to digital converter. The hardware consists of a Nano, a single general purpose op-amp, a feedback resistor, coupling capacitor, compensation capacitor and bypass capacitor. Measurement speed is 122 Hz with four... -

Precision_trimmer
Precision resistance value trim circuit using standard parts.
By using standard precision resistors in parallel and series with standard 1, 2, 5 multiple potentiometers, a precision, narrow range resistance trimmer can be created. Fixed resistors are more stable than potentiometers and the circuit reduces the effects of the potentiometer while also determining a precise range. For convenience, a Python script is used to assist in part selection. -
