MOC: Sensor GTR. A variation of the theme from my previous Supercar - I wanted to see if I could build something a supercar that looked a bit more like it was meant for the road than for the track. Very happy with the result.
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.

ZIGBEE BASED HOSPITAL AUTOMATION WITH ONLINE GRAPH AND WAP
ABSTRACT
In hospitals, the patients in the ICU need a constant monitoring of their temperature, BP and heart beat. This project is a working model which incorporates sensors to measure important parameters namely the temperature, respiratory temperature and ECG. The sensors are interfaced to computer, so that the condition of a patient can be analyzed by doctors in any part of the hospital wherever they are. Thus it reduces doctor’s work load and also gives more accurate results.
Whenever there is an abnormality felt by the patient, the particular patient will give an alarm signal, by which the doctor can rush to the patient. Even when the patient is in an unconscious condition, all the parameters will be sensed and doctor will be cautioned with a multimedia support. A saline monitoring system has been incorporated, which gives an alarm when the saline bottle is about to be empty. The data collected by the PC are recorded in separate file with date and time, which can be used for future references by the doctors.
ZigBee was designed with these applications in mind and understand the importance of low cost. For that reason, it was designed to run on the existing 8-bit MCUs that control many devices in these areas, reducing the need for additional processing power. Freescale’s 2.4 GHz band ZigBee-ready RF transceivers can be used worldwide, eliminating the need to redesign and certify a product for various markets or regions.
This technology has a desired impact on industrial and hospital automation. The hardware of this project is built on a printed circuit board, constituting PIC micro controller 30F4013. It is a versatile micro controller with in-built features such as 12 bit multi-channel ADC, USART, synchronous serial port, programmable low voltage detection circuit etc, which is to be interfaced to PC system through RS232C. The necessary signals from the external cords, like different patients temperatures can be converted in to digital form by giving them to dsPIC. The software can be easily modified for any alarm setting or record intervals since it is written in Visual Basic.
INTRODUCTION
COMPLETE BODY SCANNING SYSTEM
The objective of patient monitoring is to have a quantitative assessment of the important physiological variables of patients during critical periods of biological functions. For diagnostic and research purposes, it is necessary to know their actual value or trend of change. Patient monitoring systems are used for measuring continuously or at regular intervals, automatically, the values of the patient’s important physiological parameters. The long term objective of patient monitoring, is to decrease mortality and morbidity by
(i)Organizing and displaying information in a meaningful form to improve patient care.
(ii)Correlating multiple parameters for clear demonstration of clinical problems.
(iii)Processing the data to set alarms on the development of abnormal conditions.
(iv)Providing information, based on automated data, regarding therapy.
(v)Ensuring better care with fewer staff members.
Complete Body Scanning System deals with real time continuous monitoring and recording of some of the parameters like body temperature, electrocardiogram, respiratory temperature as well as their analysis. It also deals with the alarm system for patient call, saline checking and temperature level. With the advent of computerization in biomedical field, this project has very wide scope, due to the computerized data acquisition, monitoring and control incorporated in it. It reduces the workload of doctors and also gives more accurate results.

New sensors. More intelligent apps. Mobile-connected smart objects. Wearables. LTE. Augmented reality. Multi-platform development tools. Precision indoor location sensing. Ultra HD. Flexible screens. The list of anticipated future mobile technologies goes on and on.
On April 23, NYC Media Lab and Razorfish presented an evening of demos and discussion on Mobile Futures to learn what’s on the verge of commercialization, what’s still in the lab, and what advances will change the nature of media and communications in the future.

On my birthday in 1983 I got my first camera. With this camera, an Agfa Optima Sensor, I made my first train pictures.

The Agfamatic 100 is a viewfinder camera for Pak-Film 126 cassettes. It has an Agfa Colorstar lens with fixed focus and fixed aperture. Two shutter speeds are selectable with the ring around the lens barrel, the scale showing a cloud and a sun symbol. The camera has a single stroke advance lever that advances the film, cocks the Parator shutter and turns the flash cube holder on which magicubes can be fired as flash. On the axis of the advance lever is the red "sensor", the shutter release button hidden under a round piece of red foil. A little black plastic button side on the side unlocks the back door for opening the camera. The back door has a window for making visible the film cassette's exposure counter. The camera has an optical bright frame viewfinder of reverse Galilean type
This is a very simple digital sound sensor (Arduino Sound Sensor Module for Sensor Shield, SKU 74446) from Goodluckbuy. It’s either triggered because there’s a sound loud enough or not. The sound level threshold can be set by adjusting the pot on the PCB and the red surface mounted LED can visually show you when the device is being triggered. Much like the light sensor an op-amp is used (LM393).
The only down side is I would have liked the choice of either a digital or an analogue value much like the light sensor and it’s switch.
First small stack of the samsung KC73129 chip with the mitutoyo 10x lens and the new led module with 12 x power cree leds.
The lichting time is now shorter, 3ms, and the resolution is better. I hope to be ready end this year with the hole unit and the new controlbox.
This is a 100% crop from the Nikon D7100.
Left side with the old setup, right side with the new setup.
This light sensor works reasonably well. Goodluckbuy list it as “Electronic Brick Light Sensor Brick Module” (SKU: 75283). That’s right brick is in there twice.
From what I could find I think made by Itead. The A-D switch lets you pick the type of output from the sensor. An analogue voltage or digital high/low. The switch point for digital is adjustable via the pot and the board uses an LM358 op-amp.
Programming and working out how to apply an analogue input value to automatically adjust an output brightness value for my series of 7-segment displays proved annoying and I had little success. I believe a lot more trial and error would be needed to make this and other displays adjust with the brightness of the room. Or perhaps I’m just a bit crap.

I will be using this camera in week 71 of my 52 film cameras in 52 weeks project:

At one time, I would take my digital cameras to a technician to clean my sensors. When the cost became prohibitive, I started cleaning my own.
Here are two Youtube videos that I found helpful :
