A knob for your input needs. It uses an indent free optical encoder to keep track of your rotating input. It uses a precision Rotary encoder with ball bearing supported shaft and just feels great to use. Comes with a pre-programed Arduino Pro Mini 168.
I designed it primarily to use as an input knob but you can also use it in a machinery if you remove the knob and connect the axle. The dimensions are 75 x 60mm and about 70mm in height. The shaft is 6mm in diameter.
To make it easier to use a rotary knob in my projects
It is a butter smooth knob with a great feeling. Great for precision input to set frequency in a receiver or to set a precise value in a CNC machine etc. It uses an Arduino Pro mini 168 to keep track of the rotation. You get the rotation either on the serial port or I2C bus. On the serial port it will display a positive or negative count every 50mS if there has been motion on the knob. If you want to use I2C, simply query it on address 8 and you will get a number back indicating the motion since last query. This can be very useful if you connect to an Arduino or other MCU that is pressed for time or is going down for sleep etc. The encoder is interrupt driven to maximize speed and the unused pins on the Arduino is available on an unpopulated pin header.

I'm a electronics technician with hardware design as my speciality and software as a side line.
My interests and expertise are wide ranging but RF and Radio technology excites me the most.
I started doing electronic design in my own company when I was fresh out of school but after a few years I
became an IT Manager and have been working in the Computer industry for 30+ years at large International Software companies.
So now I'm finally going back to my roots by designing hardware for myself and for the public.
I take on custom jobs if I can fit them in.
My products are aimed to people that want to have an electronics piece to fit in to their project without to much hassle.
I try therefore to have my products pre-programmed and ready to use.
They are for the most part open in hardware and software so you can change them and tweak them.
