Hello, I am not an electrician or even well versed in circuitry but I do have an idea that I want to employ. I am currently setting off professional fireworks using a RF transmitter and receiver. Instead of using the handheld transmitter I want to build a usb device that mimics the handheld. In this way I can use the computer to send a signal to the receiver to set off the fireworks thereby giving the process much more accuracy and the ability to coordinate the fireworks with music. Any help with this would be most appreciated. Thank you.

Using the USB port sounds rather complicated.
Instead you could either design a simple parallel port interface to a UHF 433 MHz transmitter more easily, or there are ready-made solutions available on the market that do it this way. A source in the UK is quasar electronics, but they are available world-wide. The main application is to extend peripheral device range from several feet to hundreds of meters if desired.
Alternatively, the same sources probably have USB interfaces too. I never checked for those.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
