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. Comments/Suggestions to: omer@tinkersoc.org please...

Beer Bottle Night Lamp DIY Guide
- 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! 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...
- 13. That’s all folks... Thanks for listening, any questions? Comments/Suggestions to omer@tinkersoc.org please... *All copyrights/trademarks/etc belong to their respective owners yadayadayada...

- 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.
