Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would
be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate
that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views.
It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if
you would like to post something on RF Cafe's
page, please do.
Below are all of the forum threads, including all
the responses to the original posts.
Post subject: Design a USB RF Device Posted: Sat Oct 11, 2008 2:09 am

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.
