Soldering kit "VARIOSAND" , the extraordinary hourglass

The "VARIOSAND" circuit board kit is ideal for soldering beginners, all budding electronics engineers, hobby technicians and anyone who enjoys working with a soldering iron or a soldering station. More than 60 components are soldered onto the "VARIOSAND" board, including an already programmed microprocessor. Once the board is completely assembled, a great programmable hourglass is created.

The special thing about it is that a different time ("amount of sand" available for 1 - 109 minutes) can be selected each time. For example, VARIOSAND can be set to 5 minutes for a soft-boiled egg or 10 minutes for a hard-boiled egg by turning the dial. After the time has elapsed, in the meantime the "sand" has visually trickled from the top to the bottom, the beeper sounds and announces: Egg is ready!

The power supply of this intelligent hourglass is provided by a power bank or directly at a USB port, for example a mobile phone charger. This eliminates the costly use of an extra battery.

Suitable for: Schools, training centres, workshops, etc.
