Powerlimit
Set Power Limits and Voltage Offsets for Intel CPUs on Linux
...Additionally, you are able to set Power Limits for Cores, Graphics and DRAM, if your CPU supports this. Moreover, to reduce the power consumption of your CPU you can define voltage offsets for your Core, Cache, Uncore, Graphics and IO voltages. And finally, Powerlimit allows you to set a Temperature Offset to reduce the allowed maximum temperature of your CPU. Take look at the Wiki for more information -- it's easy! -

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. ... -

IGA PEH
Isogeometric Analysis (IGA) of Piezoelectric Energy Harvesters (PEH)
Isogeometric Analysis (IGA) is a modification of the Finite Element Method (FEM), which uses Non-Uniform Rational B-Splines (NURBS) as shape functions. With NURBS in the Kirchhoff-Love plate theory framework, the geometry is precisely represented, and the second-order derivatives appearing in its weak form can be efficiently approximated. In this work, we analyze piezoelectric energy harvesters (PEH) with the IGA, considering the Kirchhoff-Love plate theory. The work includes cantilever... -

rims-arduino-library
Recirculation infusion mash system library for Arduino
This library implement RIMS controls for home brewers. For definition of a RIMS, see https://tinyurl.com/j3lyuyc For me, an Arduino micro controller + a LCD Keypad shield was cheaper and a lot more customizable than a commercial PID controller. So, with this library, a commercial PID controller is unnecessary. Automatic PID tuning toolkit is also included. Temperature can be read with a thermistor, a resistance temperature detector (RTD) or any custom temperature probe. Heater is... -
