A Desktop standing engine with acrylic supports, flywheel and solenoid piston. This Solenoid Engine kit is externally electronically controlled. Piston timing comes from an opto-proximity sensor on the main flywheel and the speed regulation comes from the attached controller board, either a Raspberry PI or BBC Micro:bit. This gives a wide range of running speeds, which are adjustable with a pair of push buttons on the back of the motor to increase/decrease the speed. The speed is regulated by ‘missing’ power strokes set in the software of the controlling single board computer. Examples of controlling software is provided in the Resources section.
It is capable of running from 6-18V supply with an average current draw as low as 20mA, depending on the solenoid choice, speed and supply voltage. Piston timing and con-rod length are all adjustable and there is provision for adding 8 x M5 nuts and bolts around the flywheel for added weight. Outputs are available for monitoring of the flywheel position and solenoid on times for connection to a Raspberry Pi or micro:bit (5v outputs). An LED indicates the solenoid output.
This is the complete kit, and comprises PCB, Acrylic Hardware and a Solenoid. It is available with the electronics PCB as a kit or built and tested. I makes a great desk toy, or as a teaching aid for any piston based engine class.
Please note: The Solenoid Engine does not come with a wooden plinth. This Kit Contains small parts and is therefore not suitable for children under 5 years old.
Raspberry PI or BBC Micro:bit must be purchased elsewhere.
