you will need, a brain, two hands, eyes and some stuff below
a soldering iron.
Step 1: Parts (transmitter)
Case: I used a case from Rapid, I can't remember what the code was, but it comes with buttons and the project fits perfectly into it. Or if you are using it as a detonator you might want to make a snazzy case with lots of switches and knobs to make you feels more powerful.
i am from england and i use other companies to all you americans. i dont know if Digikey stock them or Radioshack, or you can use the internet. (dont complain to me though, its your problem)
two resistors, 1M resistor (R1) and a 150R to 400R(R2) are the values (you can get them anywhere in the world) the letter then number in the brackets for all the components relate to the layout and schematic (if you cant find these on radioshack then well...)
(c1) Ceramic disk. value; 100nF
(c2) Electrolytic. value; 100uF (you should be able to find these on radioshack as well)
(U1) HT6014 this it the encoder chip, i dont know if you can get it over in america, but it works well and it is very available in U.K.
(U2) AM-RT4-418 this is the radio module, again i dont know if you can get it in america, tough cookies if you cant.
(D1) this is a 5mm led of any colour you want the resistor value to be between 150R and 400R beware that 150R will have the Brightest LED but any lower the LED will burn out.
3V battery holder (two AAAs) you can get that in america
SW1 - SW4 these are the transmitter switches (you guessed it, it is four channel, which means that you can detonate four different things seperately. the rapid order code for these is 78-0622. see they are PCB pushes.
18 pin dil socket you can get these in america. this is to mount the chip in.
then finally (for the Transmitter at least!)
an eight pin dil switch, this is optional and is purely to encode the signal, you need the same code on both ends to be able to use this. (might come in useful so no one detonates the stuff when you are close!)
That concludes the Transmitter parts list...
