Pi in a Sega Genesis USB Hub Build

Those needle ones are cheap (in price and quality). I mean, they're like the diameter of pencils, and not the fat ones you use in Kindergarten. When I took one out to feel it, etc, it was like I could snap it in half easily. I think I'll probably get the bigger ones. But before I do that, I might check out the toolbox in the basement. My dad my actually have a file in there.
-
@hansolo77 the needle ones are what you really want. I have sets of the diamond and the regular files. You need those to do fine detail for small cuts. I recommend getting some. I bought my sets from ebay for cheap. But i have no regrets. Ever. If you only get one set get the ones without the diamond dust so you can do fine detail.
-
@hansolo77 if it were me, and your only buying one of the ones you spotted, I would go with the needle files.
Sure they are small and feel fragile (all files can potentially shatter if you drop them) if you think of some of the sizes of things you will be working on, you will find the needle files more use. Plus if your using a dremel to get close to size anyway, you don't need anything rough
On a side note, files only normally cut one way (pushing away from you) so the proper way is push the file on the material, then lift it off the material before pulling it back ready for another stroke. The only exception being diamond dust files, they work not like sandpaper

I'm going to reclaim my thread from @hansolo77 for a bit. ;)
My Mausberry arrived yesterday and it looks like it's going to fit just fine. I'm going to have to remove the strain relief post entirely,but that's OK, there won't be a USB cable dangling outside the case anyway.
I did notice that one resistor is a bit crooked on the board (above RST), but I'm assuming that Mausberry tested the circuit, so hopefully it's ok. If not, I'll try to fix it, but man, I always mess up SMT stuff, especially in close quarters.
I'm going to try to get the Mausberry circuit mounted and the USB hub wiring re-routed today. I still am searching for a good power switch, so if things go well, I'll probably just use a spare light switch as a temporary way to control the Mausberry.

After giving up on local shops and my spare electronics parts, I ordered a few of these SPST switches from Digi-Key this morning. Based on the technical drawing it has a ~3.6mm switch travel, so it should work really well for this application. Since minimum shipping was $3.40, I ordered a few switches to make it more worthwhile, and I'm sure I will have a use for them in the future. We'll see how quickly they arrive and if one actually fits.

@obsidianspider that wonky component looks a little dicey. I guess if it works ok, then it should be fine. Speaking of smt soldering, I saw this the other day, could be handy

Whenever I have had issues with smd, it has been because I couldn't heat both sides at the same time. You can also get special tips if your iron can take them

@obsidianspider Is that a 2 or 3 pin switch? Thanks for the updates, keep it up! :) I had to buy 10 switches via Newegg.com, here is what I have coming for mine, I'm thinking to use the taller switch and shape it inside the plastic slider already there instead of replacing it.
UPDATE: I didn't realize these were 3 position switches, for this build a 2 position switch is the way to go!! (sorry)
-
@obsidianspider Hiya, can you talk about how you fastened the pi3 to the inside of the hub? Looks pretty clean and secure.
-

@meyemind It's a SPST (Single Pole Single Throw) switch that looks like it has two pins on it, which is all I really need for this.
-
@meyemind i am planning on rounding the post and snuggly fitting the switch cover on it where its screw was. you might want to drill the screw hole on the fake switch cover bigger so the switch doesnt have to get sanded smaller. If a switch is hard to flip making the switch too small can make it snap off.

I hot glued nuts to the bottom of the case on one side of the Pi. Unfortunately the riser hardware I had was M3, and the Pi is made for M2.5, so I had to drill out the holes a bit, but it works. If I was going to do it again I'd probably order some M2.5 screws and nuts.
I only glued them on one side because putting them on all four holes would have raised the Pi too high and my holes were already made in the case. Plugging and unplugging my cables a few times seems like things are stable and with the case also pressing down on the ports it keeps the Pi from flopping around.
I haven't totally worked out how I am going to mount the Mausberry yet. I am leaning toward waiting until my power switch comes in the mail to mess with it.
-
@obsidianspider Thanks that's fantastic, I'll have to pick up some M 2.5 plastic nut/bolt action. I tried pretty hard to find a more simple switch like you found... ahh well :)
@edmaul69 That sounds like a good idea, nice one, thank you.
-
Finding M2.5 screws/nuts is hard to do locally. I went to 3 different hardware stores and couldn't find anything. When I was mounting my Pi in the Nintendo case, I had to settle with some #4 size screws. When did the notations of thread diameters get so complicated?

#4 is the bolt size, 40 is the number of threads per inch. When you get under 1/4" that's when you start seeing things like #10, etc. That's been the way of noting bolt sizes for as long as I've known. M2.5 means it's a 2.5mm diameter.
-
I guess I just don't shop for these things often enough. :)
-
@hansolo77 My dad was a machinist for 40 years. You pick up on these things.
-
@cyperghost Hmmm... yeah, getting more hands on, it does appear that PetRockBlog PowerBlock most likely won't fit!! Dammit. Between this thread and that Ivan guy making and selling them on ebay, it looks like all the Mausberry boards are SOLD OUT :(
Curious if you all think I can get this below to work for mine instead:
Using that 6 pin / 3 position switch I picked up with the RB-Pis-10 on/off power supply board? There is 'off', 'soft off', and 'on' options via the board, so I was thinking I could take advantage of all 3 using this switch. Is this possible? If so, how?
Might be, this isn't a smart thing to do... looking for guidance :)
Thank you in advance!

@meyemind According to the Mausberry site they're redesigning the boards, so they were probably just running out their inventory. I'm curious what the new ones will do that the old ones didn't.

@cyperghost This looks like it could be a winner no? I'm going to try and gut and use this thing...
Headset Audio Controller for PS4 DualShock Controller w/ Volume Slider
via Amazon dot com ~> http://a.co/cDFUJsV
Note: Cropped Photo NOT to scale :)@cyperghost
UPDATE w/ Pics regarding the utilization of the Volume Slider: (sorry to be all in the mix hi-jacking your post @obsidianspider, I hope this is okay :)Any advice on how to hook this up?
-
@meyemind any luck with the volume slider? I'm interested and likely to order
