You Find Makers in the Strangest Places, or My Dentist Built the Squelette Amp
I was at my prosthodontist’s office the other day getting some work done and the conversation turned to what I do for work. I told my dentist, Vu Huynh, DMD that I worked as a Web Producer for MAKE magazine. He almost dropped the cheek clamps (not a real thing…). He’s a subscriber and a […]
Turn a Pencil Drawing Into a Capacitive Sensor
Alan Chatham of Unojoy wrote an Instructable on using pencil drawings as capacitive sensors: Did you know? You can make pencil drawings reactive to touch for use with your projects! It’s really easy, and gives you a lot of flexibility in making interfaces for whatever microcontroller project you’re making. Making a capacitive touch sensor from […]
LCD Clock Syncs via Network
David Moisan hacked up his own NTP-synchronized clock from a #Twatch, the ethernet-enabled LCD backpack from our friends at Dangerous Prototypes. Head over to David’s blog to check out the code and the incredibly thorough manual he wrote for the project.
Tool Review: NEMA 23 Stepper Motor Covers

Eventually I want to use mist coolant when machining parts but I do not want to run the risk of shorting out the wiring due to spotty connections.
3D Printed Mintronics: Menta Case on Thingiverse
ThingM’s TodBot wasn’t content in keeping his Mintronics: Menta (available in the Maker Shed) in the included tin so he 3D printed his own!
HeinyBot Delivers the Beer
Daniel of Valencia, Spain, built this clever waiter bot to dispense (warm?) beer: This time, I show the operation of HeinyBot Waiter in static mode. In this mode, once activated the robot, it enters a loop oscillating movements, gestures and audio messages which only comes when we approach from the side or front to less […]
