STRINGLESS TIN CAN TELEPHONE
Geoff McIntyre @FacioErgoSum
A modern reboot of a classic children’s toy, this
Arduino-based 2.4G walkie-talkie provides a low
barrier for entry to the world of hobby electronics.
Yes it really works, up to 1 kilometer range!

WOODEN WANDERLUST MAP
Binh Thai @Binh
Adorn a wall or mirror with your world travels,
using CNC to cut out wooden continents and 3D
printing to make location markers.

3-LEGGED WALKING ROBOT
Yutaka Sato @VoidPump
Could three-legged locomotion achieve the
mobility of two-legged walking and the stability of
four-legged walking? This unique tripod robot’s
got a funky, slide-winding gait that does not exist
in the natural world!

MORSE CODE TRANSCRIBER
Jane Frauenfelder @BionicErebus
This thumb-sized handheld device lets you
practice Morse code or just write things with your
hand in your pocket without anyone noticing.
It uses an M5Stick programmed in Arduino to
convert button presses from Morse dah-dits to
alphanumeric text. Upgrade it to wirelessly send
messages to a computer or a friend with a similar
device.

DIY ELECTRIC PENNY
SKATEBOARD
Marcus Lee Wei @catleemiaw
Singapore is a hot and humid concrete jungle.
This electric pennyboard is perfect for moving
around easily, belt driven by a 6254 motor, with
longboard trucks and a tough 3D printed PETG
enclosure.

TEXT TO BRAILLE
Efe Tascioglu @EfeTascioglu
A high schooler prototyped this gadget to make
any book readable by the blind. She uses a
Raspberry Pi camera to scan the pages and
translate them to Braille, then an Arduino fires off
the Braille patterns in LEDs — just replace with
solenoids to create a readable tactile display!
