|Build Log| - DIY midi gamepad controller

Sorry no endless rotary(rotary encoder) with a gamepad.

really?

No I also tried endless rotaries on my gamepad pcb… no way :disappointed: you need some sort of “translator” because it sends 1-O-1-O-1-O-1-O…

finally the acrylic has arrived…

:smiley:

now i can take my project forward.

don’t be affraid, i’m not planing to keep the transparent finish, it will be black.

initially it was supposed to be covered with black matte adhesive film, with holes for the led, but i got this beautifull black fake leather adhesive film (finish similar to the cars dashboard) so i’m thinking of going with it…

i will post some photos in a couple of days showing the holes, led, and the finish

whoa, looks pretty badass!
love it! :smiley:

nice man! and gonna look so epic in that wooden case

whoooa that is super clean!

hi you guys,

lide pot problem solved, i have a new slide pot (not stereo) and everything works…

remember the photocell idea…

it’s not really workin…

i’ve made the following wiring scheme

and i can’t make it to work, when in light the values are random and only go to zero when hi completly cover the cell and touch it with my finger…

does anyone have experience connecting this things?

the goal is to convert a analog input to a “theremin-like” sensor…

thanks

hi,

hows it going?

im not that well versed with LDR but i think for one you should make the resistor an adjustable one,
because it sounds like the circuit is currently too sensitive, so its experiencing random values with positive light levels and is still sensitive even when covered, at the very least use a large valued resistor till you get something variable!

hi there,

the project is going well, but i’m thinking of puting the ldr aside … let’s see if i can make it to work … because these random numbers are impractical …

i will try with different resistors to see how it goes,

just a quick question, iff i had resistors, to confirm how it works, step by step, should be connected in paralel or serial? (i now it’s a stupid question…)

ok, a variable resitor would provide easier flexibility so you could fine tune,

and in series

and

let me know how it goes!

It depends on the resistance that you need. Series obviously gives you an overall higher resistance because it when resistors are in series they just add up. Resistors in parallel will be the resistances multiplied by each other divided by the resistances added to each other.

it needs to be in series to act as a pull up or pull down resistor, otherwise youll get random value because the input will be floating

good news…

the LDR photocell is working…

:smiley:

i’ve tried a different aproach…

i replaced the resistor by a pot connected has a variable resistor and it works great…

i’ve decided to keep this pot because i can now control the sensitivity of the LDR according with the environment.

i will also connect the LDR to a simple pot with a switch, like this i can toggle between pot control or LDR control…

:smiley:

i’m happy

awesome!

glad to hear it,

hows it looking? any more pics yet

pictures soon… soon…

now i’m looking for a place to make the vinil template…

:slight_smile:

Cant wait to see the progress!

I never imagined that finding decent vinyl film was so difficult…

the project is on hold just because of this…

This is awesome. Lovin the box

logo

hi there,

finaly i’ve found a place that could have the vinil film… let’s see…

in the mean time here you can have a look at the logo of the controller…

it’s going to be called “SIFÃO”, that in portuguese (in a direct translation) is a “siphon”, remember that the wood box was an old wood box from a plumber…

i love the metaphor that this is a devide that allow the flow of music from one place to another…

:smiley:
