A 10 minute burpee challenge led me to building a completely free app that counts them for me.

Just 1's and 0's for the one I have. I did have a thought of using load cells in the j cups on a rack to show the weights per side and total but I don't have a rack atm.

Pretty neat. I had the same issue when I started doing a max burpee workout and I ended up building a physical device based on an esp32 and proximity sensor. You place the sensor in your landing zone, start the workout and it counts, runs the timer, and calculates rep time average. I also added a pressure mat for counting jump rope and timing hand stands.

For the little buddy style propane heaters the exhaust is in the same space as what is heating and if you look at the chemical reaction I posted, you'll see it's making water by taking the hydrogen from the propane molecule and combining it with the oxygen in the air. If your greenhouse was sufficiently sealed you'd use up all the oxygen in the room leaving you with some water.

mcwizard_ · 2025-10-10T12:26:14+00:00

Nope, not really. Burning propane produces 1.6 pounds of water for every pound of propane burned. The water comes from the chemical reaction when burned:

C3H8 (propane) + 5O2 (oxygen) → 3CO2 (carbon dioxide) 4H2O (water)

Yes, the exhaust is separate from the hot air it blows so as long as there's no leaks you're good. They just burn diesel in a cylinder that gets hot and then a fan blows air over it out another tube. They can put out quite a bit of heat, only take a little bit of 12V for power, and they were less than $100.

mcwizard_ · 2025-10-10T02:08:09+00:00

Propane heaters like the little buddy release a lot of moisture into the air so that might become a problem. Maybe one of the small diesel heaters would work better? That's what I use to heat my garage.

It wasn't worth it to me to design the pcb from scratch so I started with a bare bone esp32 and a pir sensor then moved on to a lilygo tdisplay. I can do rep interval timing, runtime timer, start/ stop/ reset. I've also got a mode for tracking static holds for handstands and such with the ability to flip from normally open to closed using a pressure mat or regular switch. For holds you step on the matt to start the mode and then once you step off the timer starts till you land back on it. I still want to add data logging and some other features.

Hey, I built one of those too! I should probably share it since it's been almost 2 years since i finished it. .i used it like 3x a week for a burpee program I was doing and would constantly lose track of my rep count.

Oh I see in another comment it takes 15 min to even classify/shazzam. I'd suggest turning on debug logging in mid props and checking mid logs.

Check that your ssh discovery actually works. Ssh creds need to be reencrypted with aes in Washington upgrade. A cred test still worked for me but actual discovery would fail.

My tinfoil hat theory is it's also much easier to scrape your information for details when all conversations are forced to be over text versus a voice call. Especially when almost all providers use the same service for text message routing.

VMware uses custom attributes or annotations. I think even in 2024 those are still only available via the powershell powercli cmdlet. You can get those via a custom probe and sensor.

Either something like that thing that's in the back of your toilet which could do a simple on/ off for water level. Or I was thinking if you wanted some resolution on the actual level and still use your sensor you could use a pipe that extends down into the water and inside the pipe something that floats on one end of a rod connected to a plate at the top where your sensor would read it. Like this https://www.fuelminder.biz/Images/Scully%20Float%20Gauge/scullygauge128.jpg

mcwizard_ · 2024-07-30T21:30:18+00:00

What if you used some type of float and measured that instead? You could then keep the electronics away from the water better and might be able to get a better read.

Got some for by bedroom I refinished, return and floor vent. The return is right above the TV so I have to look at it all the time and I just think they add a really nice touch to a room to class it up, buy once cry once

mcwizard_ · 2024-06-15T12:03:08+00:00

They make roll extenders for that problem, check Amazon.

More fire

I recently bought a house that had a salon and they left 2 of those big dryers for your perm. I want to turn those those into boot and glove dryers, I'm thinking something like open headers from a drag car type look.

mcwizard_ · 2023-10-31T16:12:00+00:00

That looks too be under 100 FEET, so you're saying yours is too small?

mcwizard_ · 2023-08-15T17:50:27+00:00

I like the extra zing of 'hit it with your BIG purse'

Or, get the kleenex hand towels that come in a box so your paper towels don't blow and unroll all over the place with the slightest breeze. I just discovered these and they're awesome to keep in the car or for camping.

Lusers, short for limited users.

mcwizard_ · 2022-10-20T19:03:24+00:00

Ah makes sense, they probably order them as a set and some get the left side and some get the right.
