The document provides a technical overview of designing a beer bottle night lamp using capacitive touch sensing, focusing on creating a single 'button' application. It discusses various solutions and components, such as Cypress Capsense and Microchip MTouch, along with practical implementation tips for touch detection and control. The author invites questions and feedback, emphasizing the simplicity and cost-effectiveness of the discussed solutions.

1. Beer Bottle Night Lamp...a bit more than just sticking a bulb inside a bottle!Omer Kilicomer@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 SensingSerious business……if you are sensing multiple ‘touches’Single touch detection is easy‘Hot Topic’Loads of alternative solutions/vendorsThis talk is about a single ‘button’ application

5. Choices...Cypress CapSenseMicrochip mTouchAtmel (Quantum) Qtouch / maxTouchSimple PNP transistorSTMicro S-Touchetc...

6. Simple PNP TransistorCheapestKinda hacky...http://www.diylife.com/2008/02/11/build-a-touch-activated-pulsating-led-heart-valentines-card/

7. QT100A a.k.a AT42QT100AHorrible package to hand solderEasiest implementationCost not too bad...http://www.atmel.com/dyn/products/product_card_touch.asp?part_id=4451

8. QT110Simple packageSeems to be obsolete 

9. AN1202 - Capacitive Sensing with PIC10F CheapNeed to program the PIC manuallyCan be customized!http://www.microchip.com/stellent/idcplg?IdcService=SS_GET_PAGE&nodeId=1406&dDocName=en539707

10. Right, we got the ‘touch’ bit working...Next step is to create a simple controller...
