Product does exactly what it says. This is a great tool for interfacing with the receiving end of a MIDI signal. Fits nicely into a breadboard and is easy to integrate with other circuits, or probe with a scope. Took a while to get to shipping (I think it was the last in stock and was hard to find or something. Didn't feel like normal turnaround time + I don't think it was their fault), but once it got in the mail it arrived pretty quick. They threw in their LED VU meter kit along with this one, maybe as consolation for delayed shipment, or just a fluke. Either way, it was appreciated. Both kits were well constructed and did their jobs. Documentation on their site is extremely thorough, though I would have liked to see a link directly to it on the Tindie product page. Would recommend and would buy again.

I love the Heart Me! It's highly functional, works exactly as described. It looks great on clothes or a backpack. Not too bright, which is good considering the number of LEDs on the board. It doesn't have an on/off switch per se, so I use a small bit of plastic or paper between the battery and the holder when not in use.

Seller was very fast to send the item and provided a tracking number. I couldn't be happier. :)

I need about 10 more of these kits, maybe up to 15. Can you get more of these, I purchased what you had!

When I got my mini amp kit the resistor was missing. It took a day or two of emails to get a replacement mailed. The mail was delayed and was delivered several days after the estimated delivery date. Had there been documentation on the type of resistor I could have bought one myself.

Such fun and easy to build and modify. Liked it so much I bought 3 !
