AlDente
Menubar Tool to set Charge Limits and Prolong Battery Lifespan
AlDente is a MacBook battery-care app designed to extend battery lifespan by letting you set smart charge limits and monitor health over time. Instead of always charging to 100%, you can cap the maximum percentage so the battery spends less time at high voltage—one of the biggest contributors to wear. A compact menu-bar UI exposes live status, charge target, temperature, and optional protections like pausing charging when the laptop runs hot. Advanced modes help with real-world workflows: you can maintain around a target level while on AC power, calibrate periodically, or temporarily allow full charge before travel. ... -

Throttled
Workaround for Intel throttling issues in Linux
This tool was originally developed to fix Linux CPU throttling issues affecting Lenovo T480 / T480s / X1C6. The CPU package power limit (PL1/2) is forced to a value of 44 W (29 W on battery) and the temperature trip point to 95 'C (85 'C on battery) by overriding default values in MSR and MCHBAR every 5 seconds (30 on battery) to block the Embedded Controller from resetting these values to default. On systems where the EC doesn't reset the values (ex: ASUS Zenbook UX430UNR), the power limit... -

linNet
The Software for symbolic Analysis of linear Electronic Circuits
...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, operational amplifier, voltage source (constant or controlled by another voltage or current), current source (constant or controlled by voltage or another current) or a current probe (i.e. a wire). The circuit is described by a netlist. The computed formulas can be used for further investigation of the circuit or for publications or didactic purpose. An interface to GNU Octave opens up a bunch of simple to use numeric analyses and plots. -

PZEM-004T PC interface app
PC application for PZEM-004T energy meters (RS-232 or RS-485)
...PC application (Autoit script) which works with old version of PZEM-004T using RS-232 interface. Version 1.1 also supports RS-485 devices (PZEM-004T V3.0, PZEM-014/016) The program has four “displays” to show four parameters that PZEM could supply. Voltage, Current, Power and Energy. Each parameter has “Log” checkbox which enables data logging into the text field at the bottom of the application window. Each parameter has “Graph” checkbox, but only one of them (any one) could be checked at the moment. If any parameter has “Graph” and “Enable” checkboxes checked then the value of this parameter is plotted on the graph. ... -

solaton
Monitor software for the epever solar pv charge controller.
This software is used to extract operational data from the EPEVER Triron solar-PV controller, including its PV power output, battery voltage, load current, device temperatute, etc. Data collection is done in two halves: a client ("solatonclient") that talks to the controller via a serial port and RS-485 adapter, and a server ("solatonserver") that stores the information in files. The "solatonclient" sends information to the "solatonserver" over the network, and because it does not need to write to the file-system itself it can be run on a small computer such as a Raspberry Pi. -

Metal detector based on RP2040
Pulse induction metal detector using Raspberry Pi Pico board ( RP2040)
...This pulses are amplified and applied to a MOSFET device that had the searching coil in series with drain. The pulse will produce a magnetic field generated by the searching coil, and becose of eddy currents, the target will produce a very low corresponding voltage at the coil terminals. The mode this signal decay depends of target characteristics ( form, type, material ) and the distance. This is the signal we need to analyze, so it is supressed by two antiparallel diodes and passed to an operational amplifier . After amplification, the analog signal is read by one of analog input of Raspberry Pi Pico board and is analized by the software. ... -
