Any areas that the moisture detector found to be even slightly wet had to be replaced up to 2' for insurance reasons... This here's the scene of the crime. There was no real "overflow" in my bathroom - almost all of it went down the pipe hole from inside the toilet, so there was no way to know about the leak... however some "clean" water from the toilet inflow did backup from the bowl and drip onto the floor, which is where the wetness on this side came from. It's amazing what a huge job this is.
Due to poor installation (way back in 2005) my toilet overflowed recently, sending waste water from inside the toilet down the pipe into the ceiling and hallways adjacent to my suite. Let this be a lesson, boys and girls. Always have home insurance to cover the shoddy workmanship of others.

I know everyone has done this before. RFID and arduino that is. But looking at the example code it looks like the antenna is always in receive mode. I am not sure how this affects the life of the chip / reader but I thought of adding a way to detect human presence before activating the receiver.
I found some little IR heat detector (here: www.allelectronics.com/make-a-store/item/IRD-10/INFRARED-... and tossed together some analog read code and viola. Now when the IR detector detects over a certain variable heat temp it activates the RFID reader.
I will post the code and write up on my blog.
These are the Lawrence Berkeley National Laboratory (LBNL) members who helped create the Pixel Detector, which is the inner part of the Inner Detector.
Analog signal measurement of 2 fast consecutive marbles. The pulse duration of a marble is about 17 msec, the minimum distance between 2 marbles is about 47 msec. If the marbles are supplied from the transport chain, the time between 2 consecutive marbles is much longer, around 2 sec. The speed is then determined by the motor and the number of teeth between each magnet holder.
This measurement indicates that you need to be able to process a pulse of at least 15 msec in the TXT-Controller. These signals are measured at the top of the input of the module where the IR detector is located.
IR sensor voor Fischertechnik kogelbaan. De IR sensor kan werken op 5V en op 9V. Hij is niet gevoeilig voor omgevings licht. Zelfs getest in volle zon blijft hij correct werken. Het stroomverbruik door de IR diode is ongeveer 9mA en de load voor de Phototransistor is 5 mA. Burst van kogels worden mooi verwerkt. Ook getest met de TXT Controller Fischertechnik en 9V voeding.

Een nieuwe reeks enkelvoudige en dual decoders. De gebruikte chip is de AH3144 of de TLE4905L. Dit zijn unilolaire chips. De magneten moeten bijgevolg met de juiste polariteit aangebracht worden. De behuizing is voorzien voor Fischertechnik blokken. Kleine deksels zijn voorzien om de draden van de chips en plug te beschermen.
De dual decoder zijn voorzien voor quadrature decoding waardoor het aantal pulsen per schijf 4x groter wordt. De chips staan op de juiste afstand om een mooie 90 graden verschoven signaal tussen A en B te bekomen. Heb je ook een home punt nodig dan kun je hiervoor een extra enkelvoudige decoder blokje gebruiken.

Brookhaven National Lab invited both amateur and professional photographers to a three-hour, behind-the-scenes Photowalk of the laboratory on Saturday, Sept. 22, 2012. Participants were able to visit and photograph five major experimental facilities that are not usually accessible to the public including the Relativistic Heavy Ion Collider (RHIC) Tunnel, RHIC’s STAR Detector, RHIC’s PHENIX Detector, National Synchrotron Light Source, and National Synchrotron Light Source II.

Results from an excel data analyse of the sensor data of a high-speed moving object that come in focus and the flash light after the delay of the external shutter-lag time. The difference between flash light and triggerpoint give the delay. Here I have 70 scan lines at 50 usec/scan line or 3500 usec delay. Even the flash time (power) can be seen on this diagram. More flash power will give wider flash section.
At the triggerpoint the lasers are switched off. This give a very clear low level sensor signal. After the shuttter-lag delay the flashes are on and this give on all sensorlines a equal high level light. The duration of this light is show on this 3D diagram.
I use only 32 readout pixels/line at the centre of the ideal focus triggerpoint. Tomorrow I will give 64 pixels per line in order to better reflect the adjacent properties.
The aim of this presentation is to develop better algorithms for the detection.

Parts for the IR detector.
This detector can be inserted anywhere on the existing marble track. It has the dimensions for the Fischertechnik blocks. The detector works with an IR led and a photodiode as receiver. The 3D print housing is made in such a way that it shields the ambient light as much as possible. If necessary, an extra cover can be mounted afterwards on top. It has 5 mounting possibilities for optimal environmental suppression. The resistance values are given for 5V. If 9V is desired, the values can be increased slightly. The current values will also work at 9V but the current is higher. I use my regular 3 pin connection: output, VCC, GND. Because there is a pullup resistor you have to take into account that the output voltage will have the same value as the installed VCC. Therefore, do not use 9V where the output should be 5V max!
You have to be a little handy to solder the whole thing. The free space is a bit limited because of the shape.

Sue bought me this very very cool Acurite lightning detector off of Amazon. It arrived just in time for the severe storms that went through our area late last night & into the early morning hours. I left it on overnight & it counted 137 strikes. It has an indoor & outdoor setting & is very sensitive to interference from other devices such as your computer, cell phone, fluorescent lighting & microwave ovens. I had to move it several times as it tells you there is a problem.
It emits a low to medium volume beep (mutable) & a red light flashes for every time there is a strike within 25 miles which include cloud to cloud, cloud to ground & intra-cloud lightning. It may see further action later today as a cold front moves through.
