- Speed of execution
Thanks to the software optimizations discussed in Software Design we were able to achieve real time updating of both the LED panel and the LCD display with no discernable flicker. The device is extremely responsive to even the slightest tremor when the sensitivity adjust dial is set to the highest sensitivity level. We are able to poll the buttons and update the LCD screen at 30Hz and poll the accelerometers and update the LED panel at 100Hz.
Due to a lack of accurate measurement equipment and the inability to accurately position the accelerometers physically within the device, we were unable to get an exact angular reading from Digi-Lev. Our testing shows that the device is accurate to within less than 1 degree of arc.
The Digi-Lev circuitry, even in prototype form, can easily be packaged in a 12" x 3" x 2" metal case giving it a standard level form-factor and shielding the electronics entirely. All the electronics are low-voltage and low-current devices and should cause no safety concerns. The device in packaged form could be powered by a standard 9V battery.
The Digi-Lev does not emit any considerable amounts of radiation and will not interfere with any wireless or wired devices.
The usability of the device is a key selling point in that it works and feels just like an analog level. Anyone comfortable with using a level will have an easy transition to Digi-Lev. Besides, it's just about placing a block on the floor or against a wall. Anyone with a nursery school or higher academic degree will be able to correctly operate the device.
