  1. just to let you know that this is the most updated working scheme, using 3 tiny transitors instead of led drivers and a 3.7volts lithium battery. this is the easy assembly kit and all the components needed list the most updated arduino code is here (bottom page): for more info you can reach me on facebook here
  2. i just tested the new pcb board where i replaced the led drivers with 3 small transistors and it was working fine if there wasn't an error on the original scheme (i used a differente transistor schematic) so i have to reprint another stock
  3. I just looked at your blaster project - AMAZING!

    I was wondering where you got the audio files from?

    I'm looking at doing something similar but not to the same extent as yours.




    1. skyone



      mp3 sound files are available here:



      password: arduinoe11

    2. Commander Damo
  4. i have to finish the E11/sterling model first, to make boards 100% compatible with spaces, speakers, led and buttons
  5. updating this project a bit, i canceled the led drivers and moved to 3 transistors + 3 resistors 1/2w to control the 3watt RGB super bright leds i will post more updates with the scheme
  6. the 1 kohm resistor is needed between Arduino TX and DFPlayer RX because the serial input is goign at 3.3 volts while arduino otuput is 5 volts. " 4.1 Serial Communication Connect Module's serial port is 3.3V TTL level, so the default interface level is 3.3V. If the MCU system is 5V. It is recommended connect a 1K resistor in series" http://www.picaxe.com/docs/spe033.pdf btw great work!
  7. just send me a PM and i will send you the link with the zip file to download (sent you) IMPORTANT NOTE ABOUT THE PROJECT: i fixed the RESISTOR value between the MP3 Player (DF Player) and Arduino, it must be 1 KOHM instead of 10KOHM or the DF player (and clones) wont work fine or at all!
  8. that sounds great, i just ordered the MAX4466 over ebay i think it can go even with 3 AA alkaline batteries
  9. it's working great! the MAX4466 preamp microphone is very reliable
  10. just note i made an easy assembly board to make the work easier and better. Just succesfully completed its testing, the sound is loud and clear, no clipping or noise, thanks to PCB connections. With this board it will be easier to fit arduino and their components inside the PVC pipe, saves extra cables and work, no mistakes. Size WxLxH mm main unit: 91x29x21.8 drivers module: 41.5x29x18.70 bar leds module: 35.5x19.5x9.85
  11. that was a good find, by the way these sounds are streamed at 22.050 kHz / 16 bit because of the limitation of their board. In this project you can play MP3 files at 44.100 kHz (and over), that is much better quality. This is because here the limit is just the SD capacity (up 32GB!). For example, you can upload the best soundtracks from the saga or any background sounds (like the stormtrooper chatting radio from 501forum), playing them while your blaster is folded. If you need the mp3 sounds just send me a pm, i will send you the link and the password.
  12. just in case, i update the range limit of the power supply of the latest scheme with arduino pro mini, from 7,4v - 12v into 7,4v - 9v after some testing and reading around, i realized that these arduino pro mini chinese clones can't handle in this project 12 volts, it will burn their small voltage regulators. By the way, it is really unecessary 12 volts, the project just need around 7,4volts
  13. great job! i like the idea of the transparent rod to light up the bar
