Wave JT Firmware Update
A new function has been added to Wave JT. It’s auto-changer or “demo” mode. With this mode activated, Wave JT will change the animation pattern every minute. (Hence the word demo.)
You can activate this new function by holding the button down at the startup (when power is off). After each of eight LEDs has lit once, all LEDs will blink eight times. If you release the button within this period, the demo mode will be activated.
Wave JT only keeps this setting until powered down, so to get out of demo mode, turn off the power, and tap on the button again to turn on the unit.
The kits are now being shipped with this new firmware.

Wave JT – Kit and PCB
Wave JT is a tiny LED sequencer or “Larson Scanner” on steroid. It has over 16 sequence patterns, and speed can be adjusted by double/triple tapping the button. It’s the most versatile LED chaser.
Unlike other LED chasers, Wave JT controls each LED in smooth 7 bit (128 levels) brightness levels. The brightness curve is gamma-corrected like Aurora series, so the fades are visually pleasing.
Not only Wave JT versatile, it’s also energy efficient. Wave JT runs on a single AA battery, and the battery lasts for days!
Please view technical details and assembly instructions at instructables.
Wave JT is made with 100% through hole parts. No surface mount parts!
