Flashing Speed El-Panel for Motorist Enthusiasts
Speed el-panel is a sound-activated el-display that tunes in to the sound your motor makes as well as its volume.
The design resembles a speedometer, which goes from 0 to 300, depending on the amount of sound the shirt is exposed to. The speed-panel design works best when paired with a dark background. The el-Panel is powered by a small battery, which lasts a long time so there is no need to worry about the power running out while you are showing off.
