76700 Soldering set hourglass "VARIOSAND"

The circuit board kit "VARIOSAND" is ideal for soldering beginners, all budding electronic 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 each time a different time ("sand amount" available for 1 - 109 minutes) can be selected. E.g. 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 top to bottom, the beeper sounds and announces: Egg is done!

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, educational institutions, workshops and many more. Age recommendation: From 10 years Difficulty level: medium
