Description

Ich übernehme keinerlei Haftung für irgendwelche Schäden, die beim Aufbau und Betrieb elektronischer Schaltungen, an Personen oder Geräten entstehen können.

Mit maximal 12V und nie ohne Aufsicht betreiben.

Der Solenoid ist für maximal 5V ausgelegt und darf daher immer nur für kurze Impulse mit 12V betrieben werden.

 

Angeregt durch das faszinierende Model einer Solenoid Kanone von Franck alias "ffleurey" wollte ich einen Schalter bauen, der die Kanone auslöst. 

Daher habe ich eine Reflexionslichtschranke mit einem „Mosfet“ kombiniert und in die Bahn integriert.

Somit löst eine kommende Kugel die Kanone aus, und schießt eine schon bereitliegende Kugel nach oben

Angesteuert mit 12V kommt die Kugel 4cm hoch.

Eine Lötanleitung und die Datenblätter gibt es unter „Dateien“,

die Schaltpläne (Fritzing) sind bei Thingiverse erhältlich.

 

Die Schaltung könnte auch in eine eigen Platte vor dem Solenoid integriert und angeschlossen werden.

Für den Vorwiderstand der Leuchtdiode, in der Lichtschranke, bitte Werte von 470 bis 1k Ohm testen. Bei kleineren Werten reagiert die Lichtschranke schneller, kann aber auch dauernd auslösen.

Zudem kann, an Stelle der Reflexionslichtschranke, auch ein  normaler Schalter verwendet werden, siehe letztes Bild oben.

 

1x Widerstand / Resistor 33k Ohm 0,25W
1x Widerstand / Resistor 470 - 1K Ohm 1W Metalschicht/Metal Film Ø 3mm
1x Gleichrichterdiode / Diode 1 N 4001
1x Lichtschranke / Reflector switch ITR 8307 (Everlight)
1x Mosfet P-Channel IRF 9630
1x Solenoid Mini Solenoid 5V (sparkfun, adafruit, exp-tech.de)
2x Schraube / Screw Ø3x6mm

 

Englisch:

I take no responsibility for any damage that may occur to electronic devices or people during the construction and operation of this electronic devices.

Operate with a maximum of 12V and never without supervision.

The solenoid is designed for a maximum of 5V and therefore may only be operated for short pulses with 12V.

 

Inspired by the cool design of the solenoid cannon by Franck alias "ffleurey", I want build a switch that triggers the cannon. 

So I combined a reflector switch with a Mosfet and integrated them into the track.

An incoming ball release the cannon and shoot an already available ball upwards.

Powered with 12V it will be able to shoot 4cm high.

An instruction and the data sheets could be found at “Files”,

the circuit plans (Fritzing) are available at thingiverse.

 

For the resistor, which is responsible for the diode of the reflector switch, please test values from 470 to 1k Ohm. Smaller resistor values triggers the reflector switch faster, but could also turn on the switch permanently.

The circuit could also be integrated and wired up in an own plate before the solenoid.

Instead of the reflector switch, a normal switch could be used, see the last picture above.
