Skill Set: Electronics tips from “Ask MAKE”
For the past few years, we ran a column called “Ask MAKE,” where we attempted to answer reader-submitted questions about all things making.

OLED cube responds to gravity
This neat experiment uses a Teensy development board, an MMA7455L accelerometer, and an OLED display to show a cube in three dimensions. The acceleration sensor MMA7455L is used to measure the direction of the gravity vector to rotate a cube accordingly. [Via Dangerous Prototypes, thanks Ian!]
Chemical Crayon Labels
These chemical crayon labels from Etsy user, Queinteresante, are so fantastic. They are made to stick on the label of crayons, and give the chemicals that make the colors of the crayons. Awesome! I’ll take a Pheomelanin, please. [via Geek Crafts]
HiJack power and bandwidth from iPhone headset port
Project HiJack is an elegant take on an old idea. Ye-Sheng Kuo, Thomas Schmid, and Prabal Dutta from the University of Michigan’s EECS Department have done the iPhone hacking world a solid by producing one of the coolest little pieces of kit to come around in a long time. In short, the device can pull several milliwatts at 3 V and communicate at 8.82 kbaud using the iPhone’s headset port. Its design encourages the use of daughterboard peripherals to sense and collect data.
Tint ABS feedstock with a felt marker
Thingiverse contributor theorbtwo found that a simple felt marker is all it takes to tint the output from a 3D printer, so they designed and fabricated a holder for those interested in giving it a try. If you do attempt this, be forewarned that some markers may clog nozzles, so verify compatibility prior to a print run.
Describe Your Craig’s List Finds
I look on Craig’s List frequently for items, both new and old, that I can use for craft projects. Take a look at this flowchart found by Dude Craft, courtesy of Lunchbreath, on how to describe furniture listings on Craig’s List. The next time you look for a piece to refurbish on Craig’s List, check […]
