zed65 posted picture of his UniSolder 5.2 build designed by Sparkybg: Ok, first of all thanks sparky for a great project! I’ve now finished the project and it finally works. Thought I would share some of my experience when building this. Via the project log forum.
Lucky Resistor has written up documentation on his fan controller project: The fan controller described on this project page, controls one or more PWM controlled 12V PC fans. It uses the input from two precise DHT22 based temperature sensors. The MCU is an Arduino Uno, which is powered using a 12V power source. On top […]
In this video Dumitruv demonstrates his Unisolder 5.2 designed by Sparkybg: First part is the calibration with a precise 10 Ohm resistor then I plug the iron and you can see the temperature stabilizing after quite awhile. Once it stabilizes I touch the wet sponge and it goes out of whack again. Via the project […]
SZ64 posted picture of his soldering controller PCB build in the project log forum: Hi sparkybg, You have indeed perish in labor ;-) Just say that you are well. I managed to finally all up and running as it should. Via the forum.
sparkybg shared his universal soldering controller in the project log forum: The intention was to build the most universal soldering controller I can think of. It can drive any low voltage (upto 24V) iron with thermocouple or resistive sensor, in series with the heater, or separate. Here is a short list of features: – power: […]
Diego shares his latest project a WP8 bluetooth RGB LED controller with pic12f1572 16bit pwm in the forum: I made a Bluetooth board card with a pic12f1572, this pic can drive 3 output pwm at 16bit. Project files are available at Github. Via the forum.
Thrifleganger wrote this instructable detailing his Teensy MIDI USB foot controller for controlling Mobius Looper: The concept is quite simple and straightforward. You press a button, the arduino interprets the signal arriving from the button as a midi “control change” signal (typically represented as MIDI CC), and this signal can be mapped to respond to any of […]
Dilshan Jayakody writes: Workshop Organizer is light-weight, cross platform inventory controller for home-workshops. This application is specifically design to manage electronic/electrical components at home-workshops, but it can use to manage other areas of workshop including tools, machinery and mechanical components, etc. To store data, this application use SQLite database system and all the necessary runtime […]
Weiss has written up documentation on his Stepper motor controller: The reason for this project was my frustration over how much it takes to just test a simple stepper motor. To test a stepper motor you usually need some kind of MCU most likely a Arduino, your breadboard, cables, some kind of driver and other components. When […]
Zak Kemble writes: While working on an update for my CPU Usage LEDs project, I thought why not just make it into a universal RGB LED controller? The CPU Usage LEDs controller took a value between 0 and 255, worked out what colour it should be and then fade to that colour. This was very […]
Jaanus has been working on a buck-boost converter from LT3791-1: I’m building quite high power (for me) buck-boost converter for a friend. It takes in 12-45 V and has to output regulated 24 V. Total output power has to be more than 300 W. I don’t understand switching regulators well enough to build more than […]
Ray has written a detailed article about his OpenSprinkler 2.0 Arduino-based irrigation controller: OpenSprinkler is an open-source Internet / Ethernet sprinkler timer / controller based on the Arduino platform. It works with standard 24VAC sprinkler valves commonly found in household watering and irrigation systems. You may be planning to buy or have already purchased a commercial […]
William built this Karma controller and wrote a detailed explanation on his blog describing the build: My latest project is the Karma Controller, which has seven buttons to control Reddit Enhancement Suite. I made two revisions. The second is custom etched (which looks super cool!). I’ll also be sending them off to a real PCB shop for […]
Matthew of Electronics for Humans has been working on 3D printer controller: The design is based on an Atmel Atmega328 running at 8MHz (using the internal clock) at 3.3V. This is in order to keep the same voltage as the main controller board, which will be powered by the LPC1768 that only works at 3.3V […]
Zak Kemble posted his AVR based PWM fan controller build: So this is a bit of a continuation on my 555 timer based PWM controllers, but now using microcontrollers and MOSFETs instead of 555 ICs and transistors. I made 2 versions, one with switches for speeding up and down and the other with a potentiometer […]
Bill developed an Arduino library for PlayStation 2 controllers: I had to rewrite a lot of code that powers the library, there is not much left of the original code written by Shutter of Arduino forums. There were many bug fixes, now the controller should automatically be in analog mode, and the mode button should […]
Paul made a controller for the Flight Sim airplane simulator. He used the Teensyduino to connect various input and output peripherals to the famous Sim. He goes into detail on how he programed his board, and he also provided all the source code.
TinyG is a multi-axis motor controller for DIY CNC machines. Most CNC controllers receive instructions from a PC, but the TinyG executes G-code directly. By running the Gcode interpreter directly on the chip it avoids the expense and problems of trying to precisely control step timing with a general purpose computer that has other things […]
