This is an upgrade to an all-sky camera I built following Thomas Jaquin’s excellent guide ( Wireless All Sky Camera ) A common problem that occurs to sky cameras (and telescopes too) is that dew will condense on the camera dome as it gets colder at night, which obscures the view of the night sky. The solution is to add a dew heater that will heat the dome to be above the dewpoint, or the temperature at which water will condense on the dome.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
