Temp controlled cooling fan and inverted analog stick.

[DeRock89]

I have two inquiries and I'm hoping to hit two birds with one stone to only make one post.

1) How do I have a cooling fan kick on at a certain temp like with kites SAIO board instead of the fan running all of the time? I'm not using that board but I have the same cooling fan.

2) I'm using two PSP 1000 analog sticks. They work fine but up and down is inverted. I followed sotas tutorial for installing them and programming the leonardo. I pushed up for up and down for down when configuring the controls in Retropie, but it's inverted within games that use the Analog sticks like N64 games. It seems to be the left stick only that's inverted.

The solder contacts are facing south or down with both sticks. Initially I had the left ones solder contacts facing up just exactly like they are in sotas build but it was inverted then to, so I rotated to where the contacts were facing down and reglued it, but it's still invereted. Granted. I think it could have possibly been left and right that was inverted, I don't remember. I just know there was an issue with them being inverted so I rotated the stick.

Power the fan with the 5v pin going through a transistor that is connected to a GPIO pin. A script would control the fan by toggling the GPIO at whatever temps are coded.

As far as the analog sticks, I assume you can invert the control within the arduino code.

Hope this helps.

If you have the same fan that Kite is selling, DO NOT connect it to 5V. It supports only 3.3V.

In addition to HoolyHoo, you can also try to find a small circuitry with temp sensor and relay to switch on/off fan spinning... More easy than coding, but good luck to find something small enough to be usable with a GBZ

Something like this

That will work on 5V and throw 3.3V or adjustable voltage

The raspberry pi has a built in function to measure the temp already of the cpu. Adding another sensor and relay seems like unnecessary bulk to me in an already tight build. You can connect fan to 5v or 3.3v rail depending on your fan. You can even use a 12v fan and run it on the 5v rail. It will spin enough to do the job on most of those fans. Here is a link to something similar of what I was referencing.

Thanks for the information, i didn’t think of using Pi’s built in sensor that makes more sense to use GPIO then

Do you know if the air blows out the slit in the side or the actual top/bottom?

I figured I could invert it in Retropie, just push up for down, and down for up during configuration. I want to understand why this is an issue and how to fix it from a better solution then just changing the Retropie config. It confounds me that changing the orientation of the analog stick produced the same result. Logically to me, if up is down and down is up, if it's rotated 180 degrees, then down will be down, and up will be up. Why did this do nothing?

My experience with arduino coding is none existent. I just followed sotas tutorial. How do I change the code to fix this?

The air is flowing from the side... taken both from down and up to the side... it is a blower, not a fan

The answer may lie in what emulator you are using for Nintendo 64. I believe the default one (which has the best performance) isn’t a libretro emulator. Libretro emulators play nice with ES as they use RetroArch for the keyconfigs but unfortunately performance suffers with N64.

As far as the Arduino code, I haven’t looked at it to be able to answer that for you, sorry.

Edit: take a look at this part of his code.

Edit the axis you need inverted by changing the 0 to a 1.
