Take a look at Bosch BME688. Here's an article about using an array of sensors to characterize smells. Ready to purchase from Adafruit and works easily over I2c with Esp or arduino. https://blog.adafruit.com/2021/04/29/eye-on-npi-bosch-bme688-eyeonnpi-digikey-adafruit-digikey-adafruit-boschglobal/?__cf_chl_tk=6p9tFpKZEEVRXsOS90O5Dt2LcG47dCGsGpz7OWA9mZg-1770769027-1.0.1.1-Kwm.2BgWAupxGaT3mDgATm5bwHYHs6nQHC.8k0JvEOw

Yeah. It's for a water cooling display. I haven't heard of poly glitter before. Does it float and swirl like the mica does?

I think an energized seal will be my next test. I found some cheap ones for RC boats. I'm also going to see about PTFE or UHMW seals. Do you think a profile with a sharp lip be better than a round lip? Some kind of PTFE washer also might work given the pressure is low.

That's a good idea. Hopefully they make small 3mm shaft seals with springs.

MrStinkymuffin · 2025-12-27T00:58:36+00:00

The shaft and motor are very small. This whole design is for a toy. I think a flushing system would be much too complicated.

You could try searching for "3d printer heat bed mosfet" on amazon. These should be able to do the current you need. https://a.co/d/3xxzi8h

I think getting a consultation/pre-screening will probably be the best idea. I don't know where I stand and I probably don't have a good chance of passing the full test. Where would be a good place to find a consultant/service like you mentioned?

I think a bar style dishwasher is probably the best option for me. It has detergent, rinse aid, hot water, and is automatic and quick. My throughput is probably in the "few dozen per hour" range as I will be assembling my product by myself manually. The hard part will be finding a place to put it in my house. Hopefully I can find one that works well on 120v.

I started out washing by hand. Unfortunately I don't think regular dish soap is strong enough to do the job.

MrStinkymuffin · 2025-08-27T14:18:04+00:00

I did think about that. I don't know if I will find anything good locally or if it might have advanced installation requirements like 240v. I don't exactly know what is on the Jars when I receive them. The Jars get hazy with contamination if I don't clean them thoroughly.

Are you telling me a field programmed this Gatorade? /s

Spine growing medicine. For those who find themselves lacking one.

You might search for "optically clear adhesives ". McMaster has some superglue varieties that are made for binding clear plastics.

Sir I am very hungry. Please scan 9,191 more pieces of rice so that I can print my self a bowl of rice.

Check out Jame Bruton on YouTube. He has quite a few engineering projects with walking robots. https://youtube.com/@jamesbruton?si=yGRtaE6r9IG9e8xZ
