Maths are done inside the accelerometer (by Freescale), so theВ I2C channel is free for whatever you want after the startup. We have the transient detection on pin PB1 and the pulse detection on PB2, of the STM32. With this two events we can detect when the blade hits something (a pulse) or moves (a transient). At startup we tell the accelerometer to detect a вЂњpulseвЂќ (a tap) and a transient (that is a certain acceleration in a given window of time). TheВ MMA8452Q has two interrupt pins that can be set to signal pre-configured events.

We have the STM32 running the program ( source code here), that senses the buttons and processes the accelerometer indications, reads the waveforms from the serial flash and sends them to the DAC, then to the audio amplifier.Д«asically we need to detect two events: when the blade hits something and when the blade moves. Having the speaker lying on the table only makes low volume noises. So you can use any 8 ohm, 4W speaker.В If you are using a hacked-from-somewhere speaker, we recommend you to find a proper enclosure, until you find a nice pitch.

Screw terminals: 1 x speakers, 2 x optional serial port.ДЄs you can see in the video, we are using a desktop PC speaker, but just for the plastic case around it (there is no amp inside the case).

Resistors: 1 x 47K, 1 x 1 ohm, 10K potentiometer.

An AK-POWER to step down the 9V from the battery.

A SSTВ SST25VF080BВ 8Mbit serial flash (we useВ the AK-SST25VF080BВ breakout board).

A Freescale MMA8452Q accelerometer (we useВ the AK-MMA8452 breakoutВ board).

A STM32F103T8 Cortex M3 (we use the AK-STM32-DIP36 breakout board).

So, between one earthquake and the other, the project took shape.Д®nough chat. After a few days, we received the breakout boards batch, and that changed the game. So as usual, we filled the table with every little piece of hardware we found around the lab. We wanted to do another project before the end of the summer. Side note: If you are looking for a ready-to-go board for a lighsaber project, check out the new PropBoard! But donвЂ™t worry, itвЂ™s nothing hard to get. This project is a little more complex than the projects we have done before for the blog, and it will need a few external components. This time we bring you a board that simulates the sounds from a lightsaber, using low cost components.

Hello, this is Ivan, and welcome back to another complete project from Artekit.
