Electronic Clock Kit Build

NFM EC1515A Clock Kit Build

In this video I build an electronic clock kit! I attempt to do it with a cheap USB soldering iron, but don’t last long before switching back to the Hakko. I also offer a few soldering tips and useful tools and gear.

It’s a decent little clock with animated LEDs, time, date, temperature, and light sensor.

    Hey there I have the same kit ! Nice little unit indeed. Do you know of anyone being able to reprogram the chip via an Arduino to change the melodies perhaps?

    Hello Darian, I built this clock with good results – all works just fine, but I am wondering if you know about the ‘P1’ as it should be a bluetooth enabled port. I noticed a build of an earlier module the EC1204 v1.2 that incorporated the HC-06 BT module with success and he also wrote a apk for it. Would you happen to know if there is an apk for this version as I would love to have it also in bluetooth mode. Thanks – good site, thanks for your help

    Hey, nice to see the newer version of this.

    I used the older version a few years ago and installed it into a 12A rotor from a Mazda rotary engine. Made a few LED changes and it, apart from “machining” the bearing face a tad, it fit straight in.

    Got my hands on another rotor again (RX8 13B) and will make another for work lol! But will use the newer design for sure as it is a lot simpler to do.

    Hi, I have made the same kit, any problems, it work well also!
    Thanks for your article.

    Best wishes, David

    This clock is really nice. Careful construction and it worked the first time, and the acrylic case is a nice finishing touch.

    One problem though is the operation manual seems to be for v.02 firmware, and the clock is newer, probably v.03, as is silkscreened on the circuit board. The v.03 firmware seems to have many more functions that the v.02 instructions do not cover. It seems v.02 has 12, while v.03 has 24, or possibly 12 thru 24 are not programmed to do anything.
