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

Mini arcade machine on AVR Atmega328p

Do you remember yourself sitting by one of these arcade machines and playing games like Space Invaders? Well these were really popular before PC’s took over. But still they are available in many public areas and seem to be popular. Put a coin and get ready. I see one major advantage of arcade machines – they are designed to be convenient to play with few handy controls and big screen in front of you. But don’t get too comfortable because arcade machine may be very tiny so you can step on it without noticing. Actually this project tries to mimic real arcade machine. It is built around AVR Atmega328p microcontroller and 1.5 inch OLED display. Machine runs on RTOS so called FunkOS that is specially designed for low resource microcontrollers. Currently mini arcade machine allows playing Tetris, Space Invaders and Breakout. Keep eyes on it there is more to come. Continue reading
