DIY Animatronic Puppet Head

at 4:47 pm. Filed under DIY Hacks, Electronic Hacks

 

The Ben Heck Show has a cool DIY Animatronic Puppet Head project. This project listens for speech and moves the puppet mouth accordingly.

 “In this episode Ben sets out to help Backflip films with their upcoming puppet movie The Princess Knight. The film requires its actors to memorize prerecorded dialogue in order to match it with the mouth of a puppet. In this episode Ben sets out to create an animatronic head that would move its mouth automatically by detecting the highs and lows of audio waveform.”

BB-8 Robot

BB-8 Robot

 

 The BB8 Robot looks amazing, there is a lot of discussion how it is done. My bet is that there is a heavy drive mechanism in the marge sphere with an arm that can turn and tilt, This is them magnetically coupled to the top piece which simply sits on wheels.

POV Globe

 POV Globe

 

Antonin Martin-Schouler had created a nice POV Globe. IR is used for position detection, a slip ring gets power over to the globe, it is packing some serious processing power with the ARM processor running the show.

“For building the device using this tutorial, you’ll need the following material:

  • The Zybo board from Digilent
  • The Neopixel LED strip from Adafruit
  • A 12 wires slip ring like this one from Adafruit
  • The GP1A57HRJ00F Sparkfun photo interrupter breakout board and the GP1A57HR photo interrupter that you can find here and here
  • A 12V DC motor
  • A micro SD card
  • A cross-compiler for ARM processors”

Make a Emergency Phone Charger from a Pencil

at 9:16 pm. Filed under Cool Gadgets, Electronic Hacks

 

Language Warning on this video by AvE. If some swear words turn you off this video isn’t for you. This is the type of project that could come in handy when you find yourself stuck in the bush with no stores in site. We are shown how to use the resistive properties of the pencil lead to act as a voltage divider and drop the voltage to a save level for phone charging. It would be better to connect it to a 5 volt USB charge cable if one was handy since this will most likely have some voltage protection circuitry built into it, the cable could be cut and stripped with the knife in your back pocket.  That way if you are connected into the USB side of things you could slowly increase the voltage till the phone turns on and starts charging. The only thing to look out for would be the thing you are using as your voltage divider, if it has low resistance it might heat up and burn you.

Thin Film Resistor Networks

at 10:34 am. Filed under Insane Equipment

 

Dave take a close look at Thin Film Resistor Networks. These are used in various precision electronic gear where extreme precision is needed. This one is from a Keithley DMM7510 7.5 Digit Multimeter and is stamped Fluke, I didn’t now that both companies were owned by Danaher. You may have seen a similar resistor trimming design on a large scale if you have ever purchased a high current monitor shunt except they use a hack saw to cut through the metal strap before painting to dial it into spec.
