    I see that camera supports up to 36v input. Could you, please, explain how different voltage affects camera function.

    Modern Coat Rack

    I think a strip of some metal at hook contact will help to save the wall and to hang some really heavy things on it. And at the same time it would be hidden.

  • Fold Down Table - to Save Workshop Space

    Have you tried to make table top closing down to the floor? It would free space at top for more shelves and keep table parts together. And attaching table top to the wall will be a lot easier this way. You can even attach legs to the table top to save holes in the wall.

    Excellent answer, thank you. I am wondering how much more it can be seen in complete darkness as compared to the naked eye? For example if with naked eye you can see about 10m.

    It's great that power source is rechargeable, but it will be even better if you'll design a case with easy detachable battery pack to replace it on the fly, like in quadro-copters.

    Great job! Thank you for sharing your work! I hope video of Eagle Scope 1.0(ES1) in work will come soon to see it in action. I would really love to build one, but I'm not a professional in this things, so could you answer is ES1 better than available NV scopes on maket for a such price or it's just a hobby project? And you can be annoyingly descriptive if you wish;)

  • AutoBooch — Automate Your Kombucha Brewing System With a Raspberry Pi

    Hi Ra,Great answer(Devs of Instructables might add reply to an answer option aka answer to an answer). > It's something of a monster now, very thick and leathery at the top with lots of tendrils at the bottom.Thats a relief. I did the same thing, but when it's so big it have a great appetite - he eats sugar faster than i can add it and eventually it produces a lot of vinegar which destroys the taste of the drink. Now i keep pellicle max 10cm thick. And it needs around 2-4 days to produce light kombucha. As i use it substantionally for 2nd stage it's enough for me. > However, I have seen a lot of photos of weird colorations, such as black, white or dark red mold on top, usually with the obligatory "Is my SCOBY OK?". I think the answer there is usually "no," but ...

I think the answer there is usually "no," but I don't know how to tell from just the color alone.Same here. For me i decided that healthy color is the one it gets when it's young(top layer) or old(bottom layer): everything between #ffccXX - #ff77XX*. Sometimes i get more darker spots on top i suppose when it gets burned by undissolved crystals of sugar. * the color i provided is approximate, but like you said light\dark brown.> It also provides a physical barrier to the air, so the only exposure to the air is via the pellicle, so the only means of oxidation is via the bacteria in the colony matrix.Thanks to you i have some new ideas now. Have you tried to keep the 1st stage jar closed(not fully, so it won't blow up, but enough to maximally limit access to oxygen? It's interesting how it will affect the taste of kombucha at this stage(...and SCOBY itself).> If this is what you're after, what about a 'kegerator' or other carbonation system (one brand is 'SodaStream')?Thank you for a tip, but i'm searching kind of a natural solution to keep things as simple as possible. I'll try idea with balloon on top of jar. Theoretically it will "breath" accordingly to pressure. Another problem is to get oxygen and keep CO2 inside at the same time.> I find it hard to picture mentally because you want to limit exposure to oxygen, and retain pressure so the carbon dioxide dissolves adequately.Totally agree to you, but i believe that solution exist we just have to find it).> Yeast thrive on a little bit of protein. The best source of protein is... dead yeast. Have you tried another sources of protein?Best wishes,Vitaly

    Awesome instructable! I recently found out a second fermentation stage just by accident(actually year ago, but who cares) and i thought it's cool, but after reading your instructable i see that there is still a lot to learn. Could you, please, explain more about continuous primary fermentation. Your SCOBY pellicle is growing isn't it? How big(thick) do you keep it? And what do you do with remains? Do you keep the old one or new part of it?I am wondering about dark brown coloration you have on pellicle - how old is it or what is it? I have little lighter brown coloration, but on downside of pellicle. Upwards it's clean and shiny, like everything around that dark spot.Second fermentation stage is incredible and i enjoy it so much that i tried to remake it into continuous using jar with li...

Upwards it's clean and shiny, like everything around that dark spot.Second fermentation stage is incredible and i enjoy it so much that i tried to remake it into continuous using jar with lid and spigot. But the problem is that i can't fully limit access to oxygen because i couldn't find adequately strong jar for such capacity(at least 4L). Maybe you know some method or tool like brewers airlock but with manual control of over-pressure level? It would be awesome to have fizzy drink in high volume.Have you tested alcohol content in it?

  • Mindflex EEG with raw data over Bluetooth

    I checked android app source code and solution of the previously mentioned problem was quite easy. Problem was in instant retries after failed attempt. They should be divided and controlled by user. That's because after first attempt MindFlex starts to send some garbage and for the next attempt it should be restarted. Now it evolves at first attempt using UPSCALED02ALT instead of UPSCALED02 and it's cool.
