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.
  • Transcript

    • 1. Beer Bottle Night Lamp<br />...a bit more than just sticking a bulb inside a bottle!<br />Omer Kilic<br />omer@tinkersoc.org<br />
    • 2. A highly technical overview...<br />
    • 3. I am mainly going to talk about capacitive touch sensing and how to use a flip-flop+transistor as an on/off switch<br />
    • 4. Capacitive Touch Sensing<br />Serious business…<br />…if you are sensing multiple ‘touches’<br />Single touch detection is easy<br />‘Hot Topic’<br />Loads of alternative solutions/vendors<br />This talk is about a single ‘button’ application<br />
    • 5. Choices...<br />Cypress CapSense<br />Microchip mTouch<br />Atmel (Quantum) Qtouch / maxTouch<br />Simple PNP transistor<br />STMicro S-Touch<br />etc...<br />
    • 6. Simple PNP Transistor<br />Cheapest<br />Kinda hacky...<br />http://www.diylife.com/2008/02/11/build-a-touch-activated-pulsating-led-heart-valentines-card/<br />
    • 7. QT100A a.k.a AT42QT100A<br />Horrible package to hand solder<br />Easiest implementation<br />Cost not too bad...<br />http://www.atmel.com/dyn/products/product_card_touch.asp?part_id=4451<br />
    • 8. QT110<br />Simple package<br />Seems to be obsolete <br />
    • 9. AN1202 - Capacitive Sensing with PIC10F <br />Cheap<br />Need to program the PIC manually<br />Can be customized!<br />http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=1406&dDocName=en539707<br />
    • 10. Right, we got the ‘touch’ bit working...<br />Next step is to create a simple controller...<br />
    • 11. UltraTouchSwitchNG3000 (tm)<br />
    • 12. Flip-Flop?<br />(cc) flickr/comingupnext<br />
    • 13. That’s all folks...<br />Thanks for listening, any questions?<br />Comments/Suggestions to omer@tinkersoc.org please...<br />*All copyrights/trademarks/etc belong to their respective owners yadayadayada...<br />
