Great Tips on Working with Medium Density Fiberboard (MDF)
James of Stumpy Nubs has a wonderful guide to MDF. He talks through when to use it, when not to use it, how to properly join/fasten it, working with it safely in your shop, avoiding cutting it with expensive blades and bits, and more.
He also talks about preparing the edges of MDF using drywall joint compound to seal off the otherwise rough and very thirsty edge. By applying the compound and then sanding, you can get a primable/paintable edge that’s at least as smooth as the material’s surfaces.

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.
