Remote Controlled Neon Trade Show Display Sign

The Parallax trade show booth was outfitted with a 10-foot wide neon display of our logo. Visitors to the Parallax booth would be handed an infrared remote control which could be used to set one of ten different blinking sequences on the sign. The volume keys would change the speed of the flashing. The patterns include a chaser, inverse blinker, letter scroller and several other routines. Before the sign sustained any damage, we retired it to our BASIC Stamp demonstration room and mounted it to the office wall so visitors could see it in future years.

Click on Image for a close-up | The sign electronics consists of nine individual neon tube sets each on their own 120 VAC transformer. Neon can be activated without startup delays or flickering to create a unique series of lighting sequences. Each letter’s transformer is connected to a StampCI board with a 120 VAC optically isolated relay. When a BASIC Stamp® module’s I/O pin goes high an LED inside the relay activates a phototransistor circuit to allow current flow.
An infrared detector receives commands from the visitor’s universal programmable remote control. The BASIC Stamp 2p decodes the infrared receiver’s signal and performs the necessary control scheme on the optically isolated relays. The Stamp CI Board provided a safe way of making the various connections. All of the  wiring was tucked behind the sign to keep it clean.
Visitors to the Parallax booth were astounded by the amount of interactive BASIC Stamp exhibits.
For this project you need the following parts:
- Parallax BS2P24 Module (#BS2P24)
- StampCI Board (#27945)
- OPTO 22 16-module I/O Rack (#27320)
- AC output 12-140 VAC modules (#27322)
- Neon elements or other high-voltage I/O device to control
