diy projects diy projects finished projects shown telescope dew heater make a telescope dew heater this project brings together a few duinotech versatile tool inspired by the dew heaters used on telescopes it senses ambient temperature and humidity to control a small heater avoid condensation • programmable temperature setpoint • temperature target can be set above ambient or dewpoint • settings can be saved to eeprom • adjustable failsafe heater output to use if sensors are faulty • comprehensive lcd info screen duinotech duinotech thermostat we've added some colour to it by connecting some leds to give an indication of the current temperature make a duinotech thermostat here's a project that will take you into the world beyond the basics of the external library to extend our programming possibilities temperature trailer voltage jaycar.com.au make monitor trailer voltage monitor one of the guys at the office here asked if i could build an arduino device for monitoring the voltage of the 12v battery in his trailer- as now required for registration of some trailers which diy project hardcore electronics build a uno programmer the idea of using an uno to program an uno programming only takes about three seconds per wwwwwww duinotech uno programmer monitor wireless garden quinp found build a wireless garden monitor here's a project that uses two arduino boards to communicate wirelessly- the first arduino* reads a soil moisture sensor and a temperature and completely different sensors to create your own custom monitor
