Howdy folks. I have a couple spares of these https://www.amazon.com/gp/product/B01NAL6MND/?tag=pfamazon01-20 and I was thinking about repurposing one as a food dehydrator. Do I need to worry about fumes? IIRC the max temp is 150F. Will one of these help...

I got a new Ninja blender (model ss351) a few months back that was DOA. The manufacturer sent a replacement immediately, but I found a blog post on hackaday showing a simple mechanical mod that would enable me to use the motor to drive a flexible rotary tool shaft (Dremel etc). The attached...

Welp, that's why I said optional. But the app would only set pressure. After that you just open the valve.

No, no no, The purpose of the squeeze bulb is to maintain pressure on the fluid chamber so water is sprayed out of the feed tube. I want to replace the squeeze bulb with an electronic system. That way, I get - precise pressure control -automatically replace pressure as water is consumed...

I was thinking the exact same thing. I was copying the original design too closely, but the main disadvantage with your suggestion is it might be a bit difficult to make it work with every existing system.

The old fashioned way :). Plus, I'll obviously include solar charging.

This is exactly what I needed, thanks so much. But now I think about it, couldn't I simply calculate rate of flow as mass of water per unit time and determine work to be done by the bladder, given worst case scenario of tube pointed vertically upward? I mean, I'd have to find a worked example...

Yes, I specifically would like to do an electrified hydration pack. Basically identical to the one in the Amazon link, but with an electronic system that will maintain pressure as I discharge water. I'm fairly familiar with the electronic aspects of the problem. It's the reservoir itself (and...

I considered this and temporarily dismissed it for the exact reason you mentioned, it might not be able to set to low enough pressure. Besides, I want something that will automatically restore pressure as I release water from the reservoir.

As I mentioned previously, I'm trying to emulate this https://www.amazon.com/dp/B087D8XQM9/?tag=pfamazon01-20 Obviously, it's portable, but I'm afraid I don't know enough to specify minimum pressure with any confidence.

Let's save a few steps. I want to do an electronic version of this; https://www.amazon.com/dp/B087D8XQM9/?tag=pfamazon01-20 Aside from the issues people had with build quality, I'm really unclear why I need to be messing with a manual pump when I could design a system that will maintain a...

As stated in the summary, I'd like to design a chamber to store water under pressure. Nothing too powerful - basically at the level of a super soaker, maybe a little higher. The trick is, I want it to be powered and controlled electronically. But, I come from electronics land and know nothing...

Most things like this https://www.coderedheadsets.com/Assault-MOD-Waterproof-Tactical-Throat-Mic-p/assault-mod-wp.htm generally have 2 transducers. Why? If for phased array noise cancellation, can someone give a broad outline of the "summing" circuit?

Actually I got involved trying to kitbash something because the original enclosure had a crappy i/o board (dropped output voltage when input was connected). I just realized I could simply pull the terminals from the old enclosure and desolder them. Lingering effects of some health garbage make...

Solder is certainly not that hot. The iron, OTOH, hits 320c according to the onboard sensor :).
