  • KeyPi - A cheap portable Raspberry Pi 3 "Laptop" under $80

    I love people write detailed instructions and then just gloss over what is probably the most complicated step. Am I the only person in the world who doesn't just instinctively know how to take an LCD display and make it work with everything under the sun?

    Make 4 Useful Things From 9V Dead Battery

    What am I missing with the fan? Solder clip to motor; OK. Glue motor to dead(?) 9-Volt battery; Why? Glue motor to fresh 9-Volt battery; Have a fan that runs for a while, after which you're left with a motor glued to a dead battery. Why not glue the clips to the motor and add a non-momentary switch to turn it on/off? That way it can be clipped to a fresh battery as needed, like the flashlight.

    5-Minute Coasters

    Isn't one of the purposes of a coaster to protect vulnerable surfaces like wood from condensation on glasses and from any drips that might run down the sides? How is a coaster full of gaps going to do that? These might work for protecting counters from hot items, but they don't seem like the best design for coasters.

    Spraying the fishing line with a non-gloss clear spray (available under names like Dullcote) will help keep them from reflecting any light and appearing shiny.
