Overview (Reminder...)A versatile, multi-purposed, portable and low-priced measurement device that can instantly measure and display results, or store data for later re-evaluation.

The device will be easy to use and will allow some degree of monitoring and control over its environment using various measurements. In addition,

Possibility of customization and extension of feature-set in HW & SW Possibility to assemble several versions of the device Friendly interface (Cell-Phone like keyboard, LCD Display) Portable and hand-held with internal rechargeable battery Support for USB and microSD card for data transfer

So Far...

Preliminary design and characterization. Found necessary HW for all features. Detailed mechanical design in a 6.1x10x2.5cm box,

with 3D model ensuring all HW can fit in such a small

device. Electrical design for all possible hardware. (in progress) Layout.
