Cool, for creativity! Sorry not to adjust the accuracy of the stroke

Cute designer-clock with alarm clocks! Thank you all before me for a long time but all the whole not crooked not bent. Now you need to attach a sound sensor. Find a decent convenient body (to be put at different angles with a magnet on the refrigerator, etc.) and a good light filter. Power connected battery 18650 like 3,7 volts. If the accuracy of the clock will suit then there will be excellent watches
