IC 342 is a big barred spiral galaxy of morphological type SAB(rs)cd. It glows brightly at magnitude 9.1 but has a low surface brightness. This makes it challenging for small telescopes or as a ...

The smaller ATtiny microcontrollers have a limited number of pins, and therefore rely on an internal 9.6 MHz oscillator rather than an external crystal. This oscillator lacks the accuracy of a crys… ...

A metal detector used to be an entirely analogue instrument, an oscillator whose frequency changed with the inductance of its sense coil when a piece of metal approached. [Łukasz Podkalicki ...

(PhysOrg.com) -- Looking like a spider's web swirled into a spiral, Galaxy IC 342 presents its delicate pattern of dust in this image from NASA's Spitzer Space Telescope. Seen in infrared light ...

IC 342 is a hotbed of activity, with forming stars, gas and dust melding into a spiral shape around the galaxy's bright center. The Hubble image is a zoomed-in look at this central area.

While stars in our own galaxy appear as blue/white dots, the blue haze is from IC 342's collective starlight. Red shows the dust structures, which contain clumps of new stars.

(Yes, serial on ATtiny. Even ATtiny13!) – A buffer IC between target and host MCUs only connects the two while flashing – Open hardware driven by open source software. Unfortunately, ...
