Located in London, Earthshine Electronics is a source of parts and kits relate to Arduino. Other electronics or microcontroller needs also.

Digital Barograph made with SCP1000 & GLCD

Arduino Mega Project – Measurement and Data Logging. Digital Pressure Sensor and 128×64 Graphic LCD. Plots graph of current pressure, temperature variation with time.

This certainly is a good project for college students. You can also enhance it for multiple channels, mini thermal printer interface.

Stand alone remote data loggers must be able to take a Standard Thumb Drive for storing and easy retrieval of data. In urban areas a wireless internet transfer is better. In a desert or jungle a satellite data transfer or small flash storage, that can be manually collected and logged into network.

Environmental Monitoring Arduino - The Arduino Guy

The blog of ‘The Arduino Guy’ aka Mike McRoberts

The basic premise of the project is to have sensor nodes monitoring things such as temperature, pressure, humidity, light levels and so on and then send that data wirelessly back to a base station which will upload it to a web server.

At the PackRat WorkShop Lee Bell has archived Power-Energy Ideas, Mechanical Howto and Robot Designs too.  A Practical Man, His drawings are a language by itself. He has created a useful resource which will keep a DIY Enthusiast busy for many months.

Alternate Energy Plans by Lee Bell

“I already had a marine deep cycle type battery and an alternator that someone had traded me a while back in exchange for a 1hp dc treadmill motor. He was building a windmill and the car alt needed too many rpm’s for what he wanted to do. I think it’s a standard GM type.” – Lee Bell

delabs Notes

Alternate Energy, storing and managing your own small power source, are an invaluable asset for Home or Small Business.

Depending on oneself, not only develops skills but also keeps you in form always. Building an energy source cost-effectively, requires you to put in a lot of learning and building efforts.That itself may become your future Small Business

Remember Fossil Fuels are Running out fast, Only Internet Communications and Alternative Energy will keep Business Blooming.

The lifestyle has to change, The future Generations are going to face the Heat, or is it Bitter Cold ! Even Freezing ?

Coal and Steel with Steam brought about the First Industrial Boom. Then Oil created unprecedented Magic, the Second Technological Revolution. This will not last long. If only Rover found Oil in Mars, this post was not needed.

Some projects are Audio VU meters, Serial Port PIC programmer and other interesting articles. The low and high logic levels are displayed by LEDs,which are OFF if the probe tip is floating or connectedto a hi-impedance (>220k) output. A pulse transition isdetected and is indicated by turning on the LED for80 ms.

Logic State Analyzer – The analyzer fetches 300 single bit samples at a select-able rate (in 16 steps from 40 Hz to 1 MHz). It has aprogrammable start at High-to-Low or Low-to-Hightransition at input. Digital waveforms are displayed in apseudographic mode on the LCD

Engineer’s Assistant – Electronic hand-held instrument invented by mr. Voja Antonic. It’s based on Microchip’s PIC16F84 (running at 10 MHz) and a standard 2×20 character LCD-module.

Amplify uV from Sensors to mV levels for A/D Converters, which in turn may drive a display or connect to a uC means MicroController.

I have my own human interface and memory limitation. I am like a 8086 based nobody’s computer in a Penta-Core 5 Ghz Fiber-Computing World, add a 5 Teral Byte HDD. I am Obsolete, i am Legacy.

Now getting back to Bizness, the inputs from the world we interact are analog, A uV level from a Strain Gauge to measure Weight/Pressure; mV from a K Type Temperature Sensor or mV from LVDT Displacement Transducer to Gauge measure linear displacement. All these Low voltage/current, AC/DC need some signal conditioning and special construction – FOR – Amplification, Attenuation, Noise/Pickup Immunity/Rejection, Linearizion, Isolation and Transmission (long wire/wireless).

Thermocouple Amplifier Standard

This means take a small signal sample in the best possible way. The Sensor/Transducer shape and sensing/converting element/technology is chosen/developed. This low mV/uV is then Amplified/Cleaned and Transmitted.Some steps like Linearization can be done by software not all steps. Now we have a nice 0-10 V or 4-20 mA Signal which any A/D with process enthusiastically. The Digital signal will be eagerly processed by a uC with firmware, without batting a eyelid or like the kids say “look no hands” (then its plaster of paris for a few weeks).
