The prototype sensor showing the main components. We used an Arduino microcontroller for the initial prototyping. The Arduino communicates with the gyroscope and accelerometer and sends the data out over the Bluetooth radio.
Please don't try this at home. Let the expert do it.

Carnts removing services from the community - three of the big 4 banks (Westpac, ANZ and now NAB) have closed their local branches
wind sensor of weather station AR092 / DB0XHI
Antenna system of station DB0XHI:
- the vertica antenna is shared for the APRS connection (144.800 MHz) and the POCSAG amateur paging transmitter (439.9875 MHz)
- vertical 4element yagi for packet radio user access point (430.675 MHz)
- vertical yagi for packet radio link to DB0PRT
- horizontal dipole for FM radio reception
- 85cm dish for ASTRA satellite
The pickup itself has a 12inch (30cm) long leads.
Brown - Common
Blue - Normally Closed
Black - Normally Open
contacts are crimped onto the leads and then inserted into the connector

The samsung tends to make somewhat grey and drab pictures. As with the canon 260HS, I suspect there is more too it than simply saturation or colour balance, and I don't want to spend hours trying to fix every picture.
If I look at the grey bear, I see more detail in the less pixels TZ5 picture. I deliberately chose a fairly low iso, since I want a camera that works outdoors in generally decent light - thats what a compact is for - if its dim, then I use a camera with a larger sensor anyway.
Both shots at ISO400. WB is custom on both shots, set for the 'wall art picture', by pointing the WB set option at the gap between the pictures, roughly a white wall.
The clock/date is of course wrong.
The PmodTMP3 is an ambient temperature sensor built around the Microchip® TCN75A. Users may configure the output through I2C to up to 12 bits of resolution as well as setting a trigger to occur when a user defined temperature threshold is reached.
This sensor is used to take measurements of salinity, temperature, turbidity, pH, dissolved oxygen and more at ten sampling sites around Washington's Puget Sound and outer coast. Scientists are using decades of this data to find patterns in WA water quality and better understand how humans play into problems like low oxygen and ocean acidification here.
One of my larger small sensor (1/1.6") cameras that I use. Its quite good and gives good definitions, but there's not much controls you can have, so you are pretty much stuck with either the Scene mode or the "P" mode, there is also a "Smart" mode, but I don't trust it.
Not sure if its true, but this is one of the very few Kodak digital cameras that DOES apply their Perfect Touch Technology in both "P" and "Smart" modes, you can see it being added to the photos you take right after they are taken, on the LCD screen.

I followed the instructions in the manual and got rid of the dust on my D80's sensor with a single puff of air.
Dit is een print van het sensoroppervlak, voordat de cleaning plaats heeft gevonden. Vooral de linkerzijde is behoorlijk vervuild. De vlekjes zijn op mijn foto's duidelijk te zien en moeten worden verwijdert in b.v. Lightroom.
Cleaning the 30D with the Lenspen SensorKlear.
OK, so from the comparison, you can see that the result is not 100% perfect.
With further passes, this could be improved, targeting particular areas.
One this has to be kept in mind, this is with f/32. Who uses f/32 with a crop sensor body, honestly?
The images have also been processed with the purpose of highlighting filth, disregarding any actual photographic application.
So in the real world, this is just simply not noticeable - hell, I could hardly notice the same blemishes on the original sky blue image shot!
If you want to check for dust yourself, and have photoshop, it's a simple process.
1. Choose the lowest base ISO of your camera, for most people this will be ISO 200, even though your camera may go to ISO 100. Select Av mode, with zero +/- exposure compensation.
2. Choose the smallest f/stop on your lens. Most people should manage to obtain f/22, but some lenses allow smaller (darker) apertures.
3. Set your lens focus to manual and dial to infinity.
4. Shoot the clear uniform sky (or overcast).
5. Load the image into photoshop.
b) duplicate layer
c) apply auto levels to the top layer
d) desaturate the layer
You now have a representation of the shadows of where the dust and other crud is on your sensor.
To get a true picture of where the dirt is on your sensor (so that you know where to target), simply flip the image vertically by 180°.

The Cobra4 Sensor-Unit motion measures path, velocity and acceleration of an object moving in one dimension, e.g. a cart on a demonstration track. The measurement is performed via an ultrasound sensor.
Die Cobra4 Sensor-Unit Motion dient zur Messung von Weg, Geschwindigkeit und Beschleunigung eines Objektes, das sich in einer Dimension bewegt, z.B. ein Wagen auf der Rollenfahrbahn. Die Messung erfolgt berührungslos mittels Ultraschall.
The IR Range Sensor is a great way to add range detection to robotic projects that use Cerebot™ boards. The sensor detects reflective objects 10 to 80 cm away.
The sensor connects to the ADC found on all Cerebot boards. The cable maps the output pins to a 3-pin connector. The yellow wire is for the analog output signal. The pin should be connected to the analog-to-digital converter (ADC) on your microcontroller. The red wire is the Vcc power supply to the sensor and is diode-protected against reverse polarization. The black wire should be connected to the ground of the ADC.
