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!

Once again a great circuit, firmware & PCB. Just built my 1st WaveJT, I can see me investing in some more PCB’s to make colours other than Green.
Keep up the good work, I love the different patterns!

Hi,I want to use these on my dock lites. Is there any points I can hook to so that when voltage is apply it will come on. I don’t want to use the switch. The solar dock lites already have a joules thief build into the circuit.

Will this circuit work with the color-changing LEDs from your Color JT? It would look amazing if it changed color.

Hey! I planning on using this for a project. My question: what is the actual length and width in meters of the board? Sure it’s small, but how small is it? Plz answer!

Hello Jazzy,
The dimension of the PCB is 2.11 x 0.88 inch or 53.6 x 22.5 mm.
Thanks,
Aki

Awesome.
Been looking for a circuit to add into a space cruiser console for my sons bedroom.
Through this would be great to modify, run of DC supply, custom mount leds and integrate to custom buttons.
Then nearly fell off my chair at the $17 shipping price to UK.
Think I might get a US friend to by it and ship it over instead.

Hello Simon,
I know that the international shipping is high, but that’s the cheapest (and still reliable) method I can find. (USPS Priority Mail)
Being a tiny operation I don’t get the bulk rate from UPS or FedEx. I’m hoping that I will find a distributor in Europe soon…
Thanks,
Aki

can the 5mm leds be swapped with these ?http://www.ebay.com/itm/500x-Square-Yellow-12V-Car-Boat-Led-Free-Resistor-YY-/390267354912?pt=US_Light_Bulbs&hash=item5addbf3f20

Can’t guaranty, but most likely yes. Forward voltage 3v is fine. And so long as they have 2.5mm pitch leads.
