the majority of our deliveries are made abroad.
Orders are usually shipped the same day.
With Corona, however, the times for shipping per country have increased considerably.
Many customers view this with great impatience.
We have therefore decided to interrupt sales in December to wait until the situation has eased. Since paypal as payment processor does not want to be able to distinguish between different countries of the buyers, the sale has to pause for all countries - the buy buttons are deactivated.
We wish you a contemplative and healthy christmas time and hope to welcome you again as a customer in January 2021.
Motorpot remote control
Motor pots such as e.g. The ALPS RK27112MC can be remotely controlled with this module.
Nearly all audio handset switches for Philips, Grundig, Marantz (RC5) or even a universal remote control can be used to control the function.
Motorpot remote control
· Volume +/-
· 1-4 Source
· Source +/-
· Stand By
After connecting the supplied infrared receiver, a 5V supply voltage is required.
The motor of the motorpot is connected to PIN 4 and 6.
Switching on reduces the volume for a moment.
The left port can control relays for up to 4 sources.
The mute button on a remote control switches off all source relays, and when pressed again, re-activates the last known relay.
A relay for e.g. "Stand By" can be controlled with pin 15.
With push buttons to ground / GND can also be controlled manually without remote control.
· Pin 3/4: Motorpot right / left-run
· Pin 13/14: Source selection up / down
With "reverse logic", the switching signal for the relays can be inverted during operation.
Depending on the requirements in a pre-amplifier or integrated amplifier or relay cards, the module can provide the necessary signal without any changes to the existing circuit.
Pin 16 is to connect to 5 volt for inverting.
Relays are always controlled via a shield and can not be connected directly to a microcontroller because of their current consumption.
Such a shield consists of a transistor or opto-controller, which switches the coil voltage for the relay.
Depending on the wiring, this shild requires a 5V "signal high" or a 0V (GND) "signal low" from the microcontroller.

The RH8808 hand switch was chosen because it is superior in function and value to other models.
It is intuitively easy to use even in the dark and does not offer unnecessary buttons.
A functional replica of a well-known hand switch from the 90s.
Many functions and rubberized buttons, but the quality of the plastic case is rather easy to describe.
This hand switch ensures order on the living room table.
In addition to the CD player, it controls 3 other devices.
All you have to do is enter a device code from the attached list.
In addition, the hand switch has a learning function to copy functions from an existing remote control.
Macros can also be programmed to perform multiple functions at the touch of a button.
