These are the slides for my 'How to make a night lamp out of a beer bottle' talk we had in the TinkerSoc OpenMic #1 (http://bit.ly/4uo3uC)

It mostly covers different ways to detect 'touch', using capacitive touch sensing solutions and how to make a simple on-off controller using a flip-flop.

  • The memory elements in a sequential circuit are called flip-flops. A flip-flop circuit has two outputs, one for the normal value and one for the complement value of the stored bit. Binary information can enter a flip-flop in a variety of ways and gives rise to different types of flip-flops.

    • 1. Beer Bottle Night Lamp
      ...a bit more than just sticking a bulb inside a bottle!
      Omer Kilic
      omer@tinkersoc.org
    • 2. A highly technical overview...
    • 3. I am mainly going to talk about capacitive touch sensing and how to use a flip-flop+transistor as an on/off switch
    • 4. Capacitive Touch Sensing
      Serious business…
      …if you are sensing multiple ‘touches’
      Single touch detection is easy
      ‘Hot Topic’
      Loads of alternative solutions/vendors
      This talk is about a single ‘button’ application
    • 5. Choices...
      Cypress CapSense
      Microchip mTouch
      Atmel (Quantum) Qtouch / maxTouch
      Simple PNP transistor
      STMicro S-Touch
      etc...
    • 6. Simple PNP Transistor
      Cheapest
      Kinda hacky...
      http://www.diylife.com/2008/02/11/build-a-touch-activated-pulsating-led-heart-valentines-card/
    • 7. QT100A a.k.a AT42QT100A
      Horrible package to hand solder
      Easiest implementation
      Cost not too bad...
      http://www.atmel.com/dyn/products/product_card_touch.asp?part_id=4451
    • 8. QT110
      Simple package
      Seems to be obsolete 
    • 9. AN1202 - Capacitive Sensing with PIC10F
      Cheap
      Need to program the PIC manually
      Can be customized!

    • 10. Right, we got the ‘touch’ bit working...
      Next step is to create a simple controller...
    • 11. UltraTouchSwitchNG3000 (tm)
    • 12. Flip-Flop?
      (cc) flickr/comingupnext
    • 13. That’s all folks...
      Thanks for listening, any questions?
