Logan's EPIC Magic Wheelchair Halloween!


Can I get a show of hands from those who are planning on going to meet Logan and his family in Oklahoma this afternoon? Planning on leaving from MakeICT around 2:45 pm.


Me for sure. I’m also happy to drive my car or anyone else’s for all or part of the trip.


We’ll definitely want to keep an eye on that issue. I thought I might bring our mock-up along today to compare it with the actual chair.


Very good.


Does anybody have a (full-size) 4gb or smaller SD card that we can use?

We’re using an Adafruit WAV/audio shield to generate sound effects. It only supports FAT16 formatted SD cards, which have a maximum size of 4gb. I only have micro SD cards that are larger than 8gb+, and even though I’ve formatted a 4gb FAT16 partition on one, the Arduino fails to read it. I have an adapter for micro cards, but if anyone has a full-size card that’s 4gb or smaller, it would be good to eliminate another variable.


I have a 1GB card right here in my hand. I’ll bring it with me this afternoon.


I started a github project so that we can track revisions and better share our designs with the rest of the world.

Right now it just has (the start) of some Arduino code, but we should include our art, CAD designs, and any other digital assets that we can. I’ll be at the meeting tonight if anyone needs help adding them to the github project. If you prefer, you can also just give me your files and I can add them to the project for you.


Please, take good pictures and notes, as I’m at the State Fair.


Sorry to leave everyone high and dry tonight – I was pretty far gone. I’ll be sharing the latest photos from Oklahoma as soon as possible. Again, I’m really sorry. I had every intention of being there tonight, and even got down there early. I wouldn’t have missed if I thought I could have avoided it.


I took additional wheelchair photos on Saturday.


@Malissa, I spoke to Shelly (Logan’s grandmother), and she said that you could call her directly about costumes for her or Logan, sizes, whatever. Get with me privately and I’ll give you her cell.


David, we glued some foam last night. The adhesive is not up to par. Was okay for sanding and such. But when moving back to the front we noticed delamnation. We need think of another glue. I tried weld wood contact cement and had severe melting. Thoughts?


It could have been that we didn’t use enough super 77?

@Malissa im not sure everyone who was helping last night, but the ones with me were Jerry, Barbara, Roz and Rick. Combined we put in about 7.5 hrs. :smiley:


I got some ‘Iron grip silicone adhesive’ and some ‘gorilla glue’. Both test strips are on my bench drying. I will have a report this afternoon.


Okay both setup and held equally tightly. The white gorilla glue did setup the quickest and would be my choice. Both are silicone based. I will bring both down tomorrow. The wood shop has a class tonight. So I will not be there.


If you’re getting good results with white Gorilla glue, that will work for me. Let me know where I can get some and I’ll pick up a gallon.


We use Super 77 at work all the time without issue. Here’s how we do it spray both surfaces to be adhered, let dry for at least 1 min then press them together. I’ve had military drawings call for this on computer equipment cases.


I have been out of town the past couple meetings–Sorry! Do we still need the fittings in ceramic to mold plastic over? I will be at the next meeting but I will also be at the maker space during the day and most days before it gets dark from here on out, so I can get those made if they are still needed.


Speaking of this week’s meeting, I won’t be able to join since I’ll be on a flight.

I did make some time this week to breadboard some the controls, including input buttons, most of the sound effects, and stepper motor control for the snorkel. It’s probably 90% done. Code is on github and on an Arduino in a small plastic container which I left in the project area with the flashers and other electronics.

I might miss the next meeting too for a different trip, but if someone can communicate what’s needed software-wise, I’m happy to contribute remotely or when I’m back in town.

If someone can/wants to pick it up from here, I’m ok with that too. Just be aware that pins 2-5 and 10-13 are used up by the audio shield, leaving pins 6-9 and the analog pins (but no PWM on pin 9).

Also, the software expects a file called T-OR-T.WAV, which isn’t on the SD card yet. There’s a dedicated button for this sound byte which is supposed to vocalize “trick or treat!” when pressed. I thought it might be fun if we recorded the volunteers saying it together. It might not sound very good, but I thought it might be fun to try and see at least.


The body still has some work but it’s getting closer. I’m planning to round off some corners and sand it down smooth still. Next weekend we’ll be ready to foam coat and paint.
