A spectrograph lets you analyse light. Attaching it to a telescope enables you to discover all sorts of things about the stars. In fact, almost all we know about the universe has been obtained through spectroscopy!
This field of science is becoming more and more popular amongst amateur astronomers. A commercial spectrograph however will set you back € 2000 or more!
That’s why I decided to build one with a 3D printer. Of course, you’ll have to buy the optical components (slit, lenses, mirrors and grating) . But that will ‘only’ cost you about € 500. Which is a huge difference compared with a commercial spectrograph. This spectrograph is designed for telecopes which are f/8 or slower.
This is still a work-in-process project. I’ve included a STEP file of the whole design so you can change or improve upon it. Later on I will include more information on how to assemble the instrument. This will be done as a series of images that I will add in the coming days.
Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
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.
