I just hope I can actually film this! It's so easy to get excited about a project and totally let it fall apart 😅. I don't know if they'll even let me film it tomorrow, if another employee is there, or if I can't find a camera man, or if something else comes up 😅.

After a lot of grunting, and making her bottom much browner and bigger, she reads the rest of the label:

"Magic Lax! Send your problems down the Rabbit Hole! (24hr. Laxative action.)"

Kacy has to waddle up to the front of the store to pay for the "solution" to her bathroom problems.

Kacy looks around, no one's watching, so she drinks it! Oh good, she doesn't feel like she has to fill her diapers anymore!

The ln she takes one step and... Disaster!

Kacy looses control and totally fills her diaper uncomfortably!

Kacy, our innocent diaper girl, goes into a nearly empty store. She's hoping they have diapers since this is her last one, until new diapers arrive tomorrow!

But what's this? On an abandoned shelf, a tiny bottle that says

"Bathroom problem?
Drink me!"

Lol, the Pro Micro has a linear converter onboard. I'm good!

(Just ignore the one I cooked when I applied input power to the wrong pin 💀)

Thank you 🥰! I'm way too proud of it 😅

Phew! What a long thread 😅. Let me know if you have questions, though I may not answer very much if it's something I'll address in another thread or video.

Also, look out for an Amazon list soon of all the parts I got from there!

Finally, the structure! Simple: it's corregated plastic (like for signs). Easy to cut with a knife, but strong, lightweight and waterproof. I used hot glue to give it some walls and shelves to hold up the pump, battery and reservoir. Then I used VHB tape and hot glue to attach electronics.

Ugh! I had a bad negotiator at first that would only get 12V half the time, which means the Arduino would work, but when the timer was up the pump wouldn't run! So disappointing.

Also, I nearly destroyed a $100 batter with a big leak. So now I use a smaller one, and I sealed it up 😅.

The battery is a USB battery pack. Important; I have a nice one that can deliver 12 Volts, for the pump. But, I need "USB PD Negotiatior" which acts like a USB device that just asks the battery for 12V instead of 5V.

The Arduino can also run on 12V.

I'm going to upgrade to an ESP32 or 8266 very soon, so I can control it from my phone! Currently, I have to get into the backpack to set a time and start it up, and that's a pain when I also have a tube from the backpack trying to run down to my diaper 😭.

The controller is currently an Arduino Pro Micro (my favorite 🥰), on a breadboard with buttons and a screen. I'll have another thread on the software (which took a long time to sort out), but it basically lets me set a time, then controls the whole system.

That's tougher and has a better shape. I snipped a corner, forced the end of the crown bottle with the cap through that, then sealed all along the seam between the bag and the bottleneck with hot glue (I use black hot glue so it's easy to see if I missed a spot.)

So much bigger, better, easier!

But they were leaky, and didn't fit well in the backpack and didn't hold enough. I tried plumbing up two bottles, but they didn't "share" well and the plumbing sucked.

So now I have a gallon Ziploc bag! The first one nearly burst 😳, and soaked my backpack. So now I have a "freezer" Ziploc.

The reservoir was so hard to make! At first I used coupled water bottles (two "top/cap" ends glued together with a coupler). I 3D printed bottle-¼"MIP adapters to connect the bottom to the plumbing, then added a tiny hole to the top cap for vacuum relief (or else the water couldn't be sucked out.)

The pump is a cheap PC pump because it isn't *too* powerful and it is extremely quiet. But it has a huge issue: it isn't self-priming!

This means the pump needs water in it when it starts, which makes it annoying to set up the Flooder for a flood. (I'll make yet another (shorter) thread on loading)

I got some 1-way valves on Amazon too. Mostly so that when I use this for an enema, I don't make the Flooder all nasty with backwash, but I also realized this morning that they will be super useful to break the siphon effect! (More on that in a thread on testing.)

The plumbing is 12mm (or 3/8") ID silicon tubing. I got lucky and found stuff on Amazon that is flexible and easy to use, but doesn't kink too easily!

I also got a lot of ⅜" hardware from the hardware store that works with it.
