I am trying to build a circuit which will close a switch allowing current to flow through nichrome wire upon receiving an rf signal. The application is to burn flash paper, but do so from the other side of the room (aka magic show). The components I am using:
Adafruit Simple RF M4 Receiver - 315MHz Momentary Type - https://www.adafruit.com/products/1096
NTE11 NPN SI high current amp (as relay) - http://www.nteinc.com/specs/10to99/pdf/nte11.pdf
Typical 9V battery
Nichrome wire
The receiver has 3 nodes of importance: Vin, gnd, and D2 (or the output for the receiver when the proper rf signal is transmitted. The voltage output of D2 to ground is also 9v, however the current is limited to 200mA). Vin is connected to the positive bus, gnd is on the negative/ground bus. I am then connecting D2 to the base of the bjt, the collector to the positive bus, and the emitter to the nicrhome wire, with the other end of the wire on the negative bus. In theory the wire should heat up when I send the signal, however my bjt is the only part of the circuit heating up, and it rises to probably 200°F+.
Any thoughts or help would be appreciated!
