The proposed device is a simple stereo tube preamplifier, digitally controlled using a microprocessor. The device resigned from traditional rotary potentiometers and used digital potentiometers, and in addition, tube tuning indicators used as VU-meters were used. Sequential control of switching anode voltage and glow voltage allows to extend the lifetime of the lamps in the preamplifier.

The Tower Windmill from Ugears is more than a mechanical puzzle. It is an exciting adventure into the history of old England. The model is based on the Chesterton Windmill, a 17th-century cylindrical stone tower windmill that was built outside the village of Chesterton, Warwickshire county. Built around 1632-33, the Windmill was restored between 1965 and 1974 and today it is the earliest tower mill in England to retain any of its working parts.
This unique construction with an arched base was presumably built by a prominent figure of the period, Sir Edward Peyto that owned Chesterton Manor at that time. UGears 70055
