Greenweld – Surplus Electronics and Kits
Electronics Lab –
The fun way for children (or adults) to learn about electronics. This Electronics Lab contains all the parts and comprehensive illustrated instructions to enable you to assemble 130 educational experiments. Safe for children to use unaccompanied as it’s battery powered and all the components are assembled using solderless terminals. Projects you can make include: AM radio, Intruder alarm, Electronic organ, Morse key, Kitchen timer and loads more . The Electronics Discovery Lab comes in a sturdy storage box so you won’t lose any parts.
Discover Electricity –
These 3 fully-working models allow you to make an Electric Motor and a Door Bell and power them from the Electric Generator or batteries. Children will have fun building these kits and learning about the principles of electricity. Simple solderless construction makes it safe and suitable for ages 8 and up.
Located in London, Earthshine Electronics is a source of parts and kits relate to Arduino. Other electronics or microcontroller needs also.
See on right is the DFRduino Duemilanove – 100% Arduino compatible clone. Compatible with Standard Arduino Software and Shields.
Beginning Arduino – Michael McRoberts
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.

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.

Before Hams invented DIY Electronics and even before Electric Current gained any respectable position in the Manufacturing Community. The thing that was making many heads nod in unison, was Steam Engines.
Coal, Steel and then Steam Engines made the word Industrial Manufacturing very Meaningful.

“In the early 70’s while still working as an electrical engineer, and as a Dj in the evenings I was given the opportunity by a Dj friend to visit the then new BBC Radio Leeds, they wanted anyone interested to go out with recording equipment and collect interesting stories on a freelance basis, both my friend and I where keen and during the following evenings and weekends we would get together and visit youth clubs etc, collecting news and interviews returning them to the studio’s and editing them, yes on the old 1/4 inch real to real tape machines ..”
