A MSD (Mass Storage Device) USB bootloader for a PIC18F47J53 with an external SPI flash chip. I'm writing this primarily for my MPPT Solar Charger but the code is rather universal.

SolarChargerHardware

Various versions of my MPPT Solar Charger

HID_Utility

This open source (GNU GPLv3) project is aimed at simplifying the development of C# applications that communicate with USB HID (Human Interface Device) devices.

UltrasonicAnemometer

Standalone Ultrasonic Anemometer based on a PIC32

UniversalInterface

Interface that can perform any arbitrary logic function from up to 3 inputs. Multiple outputs are provided: a relay, open collector, logic 5V, logic 24V.

SolarChargerRevE_Software

Firmware of the MPPT Solar Charger Rev E (PIC18F47J53) with USB HID/MSD composite device

KeysightInstrumentCommunication

Connecting to HP/Agilent/Keysight devices via USB or GPIB

UltrasonicAnemometerHardware

Hardware design of my standalone PIC32-based Ultrasonic Anemometer

InductanceMeter_Hardware

Various inductance meters: Arduino UNO shield and PIC-based standalone version.

AnemometerLasercut

OpenSCAD models for the lasercut structure of my ultrasonic anemometer

SolarChargerApp

A windows WPF application written in C# to communicate to my MPPT Solar Charger over USB

InverterController

A device to control a frequency inverter and to measure and display RPM. Works straight off mains voltage and can be remote-controlled by a CNC controller. I've built this for my lathe but the circuit is quite universal.

DimmerHardware

Multiple versions of programmable LED dimmers, some with multiple outputs for RGB LEDs

SolarChargerRevC_Software

Firmware of the MPPT Solar Charger Rev C (PIC18F46J50) with USB HID/MSD composite device

StepperMotorController

StepperMotorController A board equipped with a 4x20 character LCD and two rotary encoders designed to controll a stepper motor driver. Supply voltage can be 12 or 24V DC for revision A and up to 60V DC for revision B. The pinout matches the Planet CNC 6.0 amps controller (https://planet-cnc.com/product/motordriver-6-0a-256/). Firmware will be shared here as well as soon as it exists.

Game Maker Language

RPM_Meter_Hardware

A nicely made RPM meter that takes a quadrature encoder input and displays the result on a 4-digit display. The input signals are properly filtered and schmitt-triggered first and a reconstructed signal is made available as an output. Works with any supply voltage in the range of 6 to 30V DC and is reverse polarity protected.

SequencerHardware

RX/TX Sequencer with 3 Reed Relay outputs

InverterControllerSoftware

Firmware for my Inverter Controller. Written in C for a PIC16F18855

HexFileParser

Two command line tools (one written in C#, one in C) that parse, error-check and decode .hex files, i.e. the files one uses to program microcontrollers.

RelayController

Properly hardware debounces up to 6 inputs and provides corresponding open-collector outputs with free-wheeling diodes included able to drive 500mA each

SensorInterface

Interface between the CNC controller of my mill, a tool lenght probe and a 3D probe

YaskawaSpeedControl

A fully-featured interface between a CNC controller and a Yaskawa Sigma7 servo drive

ProgrammableDimmer_Software

Firmware for the universal programmable 4-channel LED dimmer based on a PIC16F18325

Sequencer_Software

RX/TX Sequencer with 3 Reed Relay outputs

StepperMotorController_Software_RevB

Firmware for my StepperMotorController. To be used with the USB bootloader.

StepperMotorController_Software

Firmware for my StepperMotorController. Written in C using the Microchip XC8 compiler.

UserInterface

Easy-to-use, low-power user interface with I2C interface and 20x4 character LCD

BeaconKeyerHardware

A PIC-based beacon keyer design

InductanceMeter_Software

Software for my standalone inductance meter. It's written in C for the Mikroelektronika MikroC for PIC compiler.

SMeter_Hardware

There are 2 eagle projects. The display unit and the db-linear amplifier. The display unit serves multiple purposes. It provides clean, linearly regulated and filtered plus/minus 5V supply to the amplifier, it measures its output and displays it on the 2x16 character LCD. It can also communicate with a computer via USB (see SMeterApp).

SMeter_Software

Embedded software for the display unit of my S-Meter. Measures the output of the db-linear amplifier (see SMeter_Hardware), displays it on a 2x16 character LCD and communicates over USB with a host (see SMeterApp).

SevenSegmentDisplay

A project for beginners in the field of microcontrollers. Two 74HC595 shift registers control two 7-segment (plus decimal point) displays via an SPI interface.

MotorController_Hardware

ToolChanger

Some hardware logic for the tool changer of my milling machine. No tool change while spindle is turning etc...

RPM_Meter_Software

Software / firmware for my RPM meter

Robot_Hardware

Eagle files for my robot with two stepper motors and some other stuff

HoldingCurrentLimiter

A little circuit designed to limit the holding current of a relay. While it limits the holding current, it does not limit the current when the relay is switched. Current is adjustable via a pot.

LubricatonController_Hardware

Hardware of my Central Lubrication Controller

RotaryTableApp

An application written in C# that communicates with my stepper motor / rotary table controller via USB.
