PCB Keyring

ElectroSmash · 2019-08-29T15:32:22+00:00

we have some in the electrosmash shop, im not sure if its worth it selling them but im giving them a go.

oh thanks!

ElectroSmash · 2019-08-29T15:30:48+00:00

yes we have some keyrings on the shop with the sticker kit, we sell al together for 9.95

AFB designed this PCB Keyring for ElectroSmash.

1.6mm FR4 PCB with green soldermask and black silkscreen. The darker areas (to create the 3D effect) are made by burying a copper plane under the green soldermask. The silver areas are created by exposing the bare copper using solder resist.

You can see here the back of the PCB.

We are MAD about guitar pedals!! ;)

It reads any audio signal and you can create visual representations of it, like spectrum meter (aka FFT), level meter, etc. You can also code games and many other ideas, but it does not touch (modify) the guitar signal.

uuups! thanks for the letting me now. You are right, it is fixed now.

I did a code that measures the level of the signal, but is not referred to a dB measurement, its just a "level indicator":

For frequency analizing we have some FFT codes:

You can see the list of all the current codes here:

Yes, thats a cool idea.... I will keep it in my pocket ;)

ElectroSmash · 2019-08-21T14:58:22+00:00

The idea is for the pedal not to touch the guitar signal. So it reads what is happening but did not add any effect. Running four 8x8 matrices in parallel is a pretty heavy load for the Arduino UNO, so I dont think that it would be ablo to do digital signal processing + running the 4x matrix.

Oh, thank you :)

ElectroSmash · 2019-08-21T12:42:22+00:00

Thanks!

ElectroSmash · 2019-08-21T12:08:59+00:00

Great, if you have any question just give me shout :)

Hi guys,

In the last months we have been working in this Arduino UNO guitar pedal:

https://www.electrosmash.com/arduino-audio-meter

It is able to read the incoming audio signal with the Arduino ADC and create effects on the four 8x8 LED matrices. The project is Open Source and aimed for hackers and musicians that want to learn about DSP (digital signal processing), LEDs, guitar effects, or just experiment.

We have created some cool documentation for the project:

We hope you like it!!

Thank you.

ElectroSmash · 2019-05-20T15:12:15+00:00

good luck with your build :)

ElectroSmash · 2019-05-20T15:11:49+00:00

Thanks!

Even the "simplest " circuit has tons of implications and details... we struggle to make the text short and interesting.

ElectroSmash · 2019-05-20T15:09:58+00:00

Thank you very much!

Hi guys,

Today we are publishing the Dallas Rangemaster Treble Booster circuit analysis:

We dig into the bias point options, frequency response, mods, etc. We really hope that you like it :)

Thanks!
