Watch With Oscilloscope

This is a must have watch for geeks. It combined all the features of a watch along with an oscilloscope and surprisingly a waveform generator. I would say it’s the nerdiest thing you can put on your wrist. Another good thing about the watch, that it’s hack able. With access to hardware design, users can write their own applications. The brain of the device is a powerful 8-bit XMEGA microcontroller, easy to program in C or assembly. The estimated battery life will be over 30 days on each charge without using the oscilloscope. When using the oscilloscope, the battery will last about 12 hours.  The Oscilloscope Watch uses a 1.28″ e-paper display which combines fast refresh rate and great contrast, with a very low power consumption. It has features of oscilloscope, multimeter, freqency counter, logic analyzer, and a waveform generator. The project is being worked upon to make the enclosure water/ splash proof so as when it’s raining outside, the watch didn’t get destroyed. The enclosure are made out of plastic and are splash proof. I have to say, what… Continue reading

Oscilloscopes Redefined

Everyone related to electronics must have used an oscilloscope. What, if you can carry it in your pocket, to where you go? With XPROTOLAB portable, you can carry the oscilloscope in your pocket. The Xprotolab Portable is a small mixed signal oscilloscope with an arbitrary waveform generator and protocol sniffer. It’ a portable version of Xprotolab which is a mixed signal oscilloscope with an arbitrary waveform generator in a DIP module. It measures only 1 x 1.6 inches, and can be mounted directly on a breadboard. The Xprotolab can also be used as a development board for the AVR XMEGA microcontroller. At first sight it was hard to believe that all of the useful functions that have been crammed into one tiny device!  The device is built around an ATMEGA32A4U and an OLED display and also has four tactile switches. It has a maximum sampling rate of 2MSPS and features 2 analog and 8 digital inputs. The scope is amazingly useful despite its limited resolution and the triggering options. The price is very reasonable and the documentation is excellent. Continue reading

Single board AVR DSO project

Digital oscilloscope projects or so called DSO are always interesting, because there are speed and quality concurring on limited resources. Vassilis Seradiris constructed single board AVR oscilloscope based on Atmega32 microcontroller.   His attempt was to build DSO scope programmed only in C language instead of ASM. This scope can display maximum 5kHz square signal while for other signals frequency is lower (~1kHz). Maximum signal voltage input 24V(DC)/30V(AC). Wave is displayed on 128×64 pixel graphical LCD. Scope has auto triggering function which allows to view continuous signals like they are stopped. If signal isn’t continuous – it can be frozen by pressing button and analyzed. Project files. Really cool project and may be practical for those who work with low frequency signals. Continue reading
