Has anyone ever user the dorji 433mhz modules at 3volts without the antenna? I need to use a coin battery to power the transmitter and 3.7 volts on the receiver. I am wondering what kind of range I would get at this voltage with no antenna attached on the transmitter or receiver.

I have been creating a few projects for a few magician friends of mine. One project was a simple transmitter that once a button was pressed a vibration motor silently vibrated on the receiver unit. Basically a secret coding tool...Very simple stuff here. I was using the 08m2 mcu with the cheap...

I have built a project with a sparkfun ID-12 RFID reader and a vibration motor. I was able to get the RFID reader to read RFID cards properly with the following code: 'This program Reads RFID cards and displays the 10 digit HEX number in the terminal Pause 2000 SetFreq M8 SerTxd( "Starting"...

I have a 08m2 Picaxe microcontroller on a protoboard that I am running at 5 volts with an ID-12 RFID reader. I would like to add a pager motor to the project board. I have a 3V Radioshack Vibration motor with a 95Ma current rating that I would like to add to the project. I know I cannot simply...

I am new to PICAXE and learning so I am learning but I have a question: I have my 08m hooked up to an ID-12 RFID reader and I am reading Parallax RFID cards. the code I am running to test is: Pause 2000 SetFreq M8 SerTxd( "Starting", CR, LF ) Do Serin 2, N9600_8, ( $02 ), b0, b1, b2, b3, b4...
