Make use of iCamera 1000 units?

I have 3 "iCamera 1000" camera units laying around. I do not have the rest of the security system they are designed to function with, but there has to be some way to make use of them and have some fun. I have lots of cat 6 cable and RJ45 connectors to custom make a cable if anyone has the expertise to figure out how to make use of these. Before posting here, I searched and searched here and on Google but only found information regarding the "normal" application of these cameras..... I was hoping for something more outside the box which is why I am here. I included a front/back picture. Thanks for any ideas!!

Dog hydrotherapy pool?

Has anyone attempted to make their own hydrotherapy pool for a dog? The vet has one--it's a big boxy thing, portable (in theory), and has water jets to simulate a lap pool/endless pool. I want to try to make one myself...any suggestions?

Squishy Silicone (shore hardness 30-10) with 4 ingredients

I owe my findings to the maker of "Oomoo" and community of hobbyists; thank you everybody! I needed squishy silicone, and the random knowledge I found here helped me with the puzzle pieces. The pink rectangle that you see in the pictures has the consistency of a gummy bear (shore hardness ~10). Grab: GE Silicone 1 caulk (or equivalent) Caulk Gun Odorless Mineral Spirits Baby Oil (Mineral oil) Acrylic Paint Sandwich zip baggies (medium large will help you) Cutting tool Mold negative (I use play doh because I only need basic shapes) Try to avoid glass... Don't use glass. A way to measure Tablespoons ADVISORY- your silicone (should) smell of vinegar and your mineral spirits will be potent of fumes.. and flammable. Use ventilation and protect your eyes. Your only saving grace is the baby oil scent. Okay. Grab the (new) silicone caulk and cut the whole pointy tip off of the tube, making a flush cylinder. Load that bad boy in the gun. Open a plastic baggie, and fill it with: 2 tbsp Mineral Spirits 1 tbsp Baby Oil (Mineral oil) Then shoot one full shot of silicone directly into the oily puddle of liquid. Close the baggie, leaving a little air. Find a way to mix it. I lay the bag on a smooth table and repeatedly iron the baggie with my pinky. You have 20+ minutes pot time, so be thorough. You should now have a clear 'spit' like liquid that runs, similar the two liquids you just mixed. Open the bag. Add: 1 drop acrylic/oil paint Close it, and repeat the mixing until your color is even throughout the liquid. Turn your baggie sideways and cut a small triangle from one of the bottom corners. Carefully tilt the bag like an icing baster and pour the silicone into your mold negative. This method is clean and offers control. You can squeeze ALL of your mix into the pour, as well as combat air bubbles. Don't touch it for 3 hours. Better yet, leave it for three days. It takes this long for the shrinkage to happen. You can avoid shrinkage if you use xylene instead of mineral spirits, but it is not available to me. The color will become opaque in this time as well. You now have very squishy silicone. I have tried many other pours and I can't manage to get the cured squishy consistency without mixing a liquid to start. A goop is preferable to me because I can use it a caulk, still, allowing me to 'draw' silicone positives. To achieve a shore hardness of ~30 Repeat the steps above, but now use: 1 tbsp Mineral Spirits 1 tbsp Baby Oil (mineral spirits) This will have an initially 'goopier' mix, and you will have similar pot/cure time, but no shrinkage. It will be oily until you repeatedly dry it. The picture of four silicone squares illustrates my last advice. Each mix has only one drop of the same pink acrylic paint. You may want to experiment with how much color you want. Far Left: the gummy bear mix 2:1 softest Inner Left: the hardness 30 mix 1:1 Inner Right: FAILURE did not cure (1/2 tbsp baby oil, 1tbsp mineral spirits) Far Right: FAILURE did not cure (2 tbsp baby oil, 1 tbsp mineral spirits) toughest The two squares on the right could have been made with just silicone, mineral spirits and NO baby oil. Maybe, add ~3 drops of glycerin and I could have had the same hardness AND a thurough cure, but I want the squishy. Hopefully this helps.

I bought a Haier wine cellar for $5 that no longer cools below 81 degrees, what would cause that? Answered

I know it's a thermoelectric cooler. When I got it home the inside temp read 101. I left it on for several hours and it went down to 81. But it's set to go down to 46 (there is no lower setting than that) but it won't get cooler than 81 degrees (not even after being on for days). When I removed the back, it looks pretty simple, there is a large fan on top of a large heat sink on the back. From the inside, there is a second large fan that blows into the cooling compartment. I'm trying to figure out how it works so I can either fix it or turn it into something else.

How to make a single frequency am radio receiver?

I know how to make a 1 mhz am radio transmitter, so now I want to make a 1 mhz radio receiver to receive audio. I would prefer to not have to wind any coils and just make solid state with few components. Do I need to have a coil to receive the radio waves? Also can someone link me to an explanation or explain how I can demodulate with a 1 mhz crystal oscillator. I don't want a link to 'how to make an am radio' I can do that myself. I just want to know A. how to receive the radio signals hopefully without a coil (only using a variable cap?) and B. How I can demodulate using a crystal oscillator. Can I somehow receive the signal using an oscillator like was done with a 555 timer here https://www.instructables.com/id/555-timer-radio/ Links to schematics / pictures of schematics must appreciated? Thank you

LED's and Arduino Question,,,,

LED's and Arduino Question,,,, I am looking to install LED lights (a LOT) in a 1:18 diecast car. I'm slowly grasping the wire schematics, and feel the install wont be too tough (yeah right)... But, I am looking for a way to turn the lights on/off. Since I will put lights (or extend fiber optics to) tail lights, blinkers (front and rear) brake lights, fog lights, running (marker) lights, head lights, and a bevy of interior point lights via a Fiber Optic layout. My main question is the lighting controls. As you can see, I need to be able to switch a variety of lights, in different modes,,, Blinking for 4-way, blinking for turn signal, all on, just running lights on, and brakes lights on....Anyone care (dare) to step in? Similar to this... http://youtu.be/WbqQ0tUtX3U

Fishing the traditional way

A while ago I had a very bad day of fishing in terms of catching something for my frying pan or freezer.Same story for the old bloke sitting a few meters away from me.So we decided to pass some time with useless chats about our previous record fish we caught.While the old bloke changed bait I noticed that he did not have a hook at the end of the line.....What is that contraption and how do you catch fish with it?Old bloke laughed and said he goes hunting a lot too and always keeps the antlers from deer and such.Instead of a hook he used a round and pointy bar with a little notch slightly off the middle.Couldn't figure out how this possibly could hook a fish, so got a bigger laugh for it this time :("Make a loose fist, put it in and then pull on the line." he said and I was dumb enough to assume it would not work :(Figure it out by getting two bleeding pricks...Fish swallows the "stick" inside the bait and one there is some pull one pointy end will always get stuck.The other moves until there is no room to move anymore and the fish is spiked up for good.Only downside is that one you get a fish too big it might not grab - bad luck then LOLThis approach instead of steel hooks reminded me of the bamboo fishing poles my grandfather used to make.Be it for eel, trout, carp or even from the boat for pollock and sardine - he loved his bamboo.Even made me my fisrt fly fishing rod from a piece of bamboo :)The old guy however had more than hand made rods or horn needles as hooks.When his hands were still as good as his eyes he even made flies from these horn sticks!He explained the process to me but I never had the patience for normal flies and doing this with horn sticks and estimating how big the biggest fish might be while making sure it is neither too heavy nor fails to float...What I really liked about this otherwise wasted fishing day was the stories I got from the old man."You don't need fancy or oversensitive gear to fish, a safety pin and some packing coad do just fine if you are hungry!"Best story was how he caught a 2m gummy shark with a hand line meant to catch some sardines for bait.I could really his 3 hour struggle to get the thing on board LOLWhat are your most successfull old school or just plain weird catches with something a real sports fisherman would not even touch to cast?

Polarity of fan motor?

Recently I had occasion to change the small fan that cool the aluminum fins just above the exturder. Not paying too much attention to the polarity of the 12 volt supply voltage, I figured that if was turning the wrong way, I could easily change the plus and minus connection. When I fired up the controller, I thought it was turning the wrong way and I changed the polarity. It then wouldn't turn at all. Changing it back to the original polarity, it worked fine. It is normal to have the fan polarized, and if so, what is the proper direction of air flow?Alan

How do you know if a capacitor is finished charging to its full potential? Also if you were to have a group of capacitors linked together in a series or parallel fashion how could you determine whether or not the capacitors were charged completely? I am mainly referring to polarized capacitors.

Convert 5VDC to 3.7VDC?

Hi everybody ! I'm currently working on a speaker project, and I want it to be powered by 4x 18650 3400mAh 3.7V batteries in parallel, but when they are recharged (with a separated 18650 wall charger), I want to be able to power my speaker from a wall power supply. The idea is to get the 5v power supply voltage down to something between 3.7v and 4.2v, in order to mimic the battery voltage. I already chose this one which is a 10amp-capable power supply in order to be sure to always give the speaker enough current (speaker current consumption is between 0,55 at medium volume and 3 amps a maximum volume). I first thought that i would use this board to convert 5v to 3,7v but it's only able to output 1.25 amps max so I need to figure out a way to convert 5v to 3.7-4.2v without loosing a lot of current. I've heard of low dropout regulator (LDO) but I cannot find one capable of delivering 4amps or more... Any help is appreciated ! Mahot

"Open source" marketing research, anyone?

                                  Calling any and all market research buffs!   "I need help finding my target market, but I can't afford to pay the giants in the business who have many many years of experience and probably have an agenda."   I'm sure that has been said, and heard, many times, and now its my turn. I had a thought recently about how I could find a market for a product I'm working on. Since I intend to release it openly, I want most of the side stuff the project spits out along the way to be open as well.   My idea centers around a collaborative and "smart" marketing research system. Of course there would be problems inherent to the system (trolls and SPAM, for instance) that could be remedied in a similar fashion to Wikipedia or Kickstarter. Now that I've put this idea out there, who wants to make it happen?

Help wanted in designing a switching circuit.

Problem is that there is a combination of any one on at a time or all three at once or none on. I can’t connect all 3 outputs together to drive the pump as the inkbirds will get damaged. Can anybody draw me a circuit whereby if any combination of of inkbirds switch 230v only one output is switched to the pump. Have attached a diagram showing all outputs connected together but have been told that mains connected across the Inkbird output will probably damage it.

How do you keep deer out of your garden without a fence? Answered

I just planted a small victory garden in my backyard. The yard is mostly a steep hill, and the patch shown is just about the largest, flattest part. I planted cabbage, cauliflower, lettuce, artichokes, and spinach. A few days later, everything but the artichokes has been munched, and there are hoof-prints all over. So, knowing I don't want to build a huge fence for a small hobby-level garden, how should I keep deer out?I live in a fairly urban Oakland, CA neighborhood, so despite what one might think -- and what I might enjoy --, hunting the deer is out. I read that human hair works as a repellent, but I don't need a hair cut anytime soon. Among other ideas, Country Wisdom and Know How suggests that I put a 4-foot barrier of chicken wire on the ground around the garden. Apparently, deer don't like to walk on chicken wire. Has anyone tried putting chicken wire on the ground? They also suggest tying a dog up in the yard near the garden, but I'm more inclined to the chicken wire idea.

Homemade hydro excavator?

I recently stumbled onto a website that sold a special hose and powerhead that allowed a typical pressure washer to be used as a sewer jetter (unclogging sewer lines).  I was blown away.  So simple.  Pure genius. Then it occurred to me:   A standard pressure washer could be used as part of homemade hydro excavator -- a digging tool that liquefies soil and removes it with a vacuum.  These machines can excavate around pipes without damage and make surgical-style incisions in the earth. Very precise. Very fast.  Factory made hydro excavators are *very* expensive and they typically rent for $350.00+ per day.   To turn a pressure washer into a hydro excavator, you'd need an economical homebuilt vacuum tank to suck up the liquefied soil and a vacuum hose attachment for the wand.  The excavated liquefied soil is very heavy -- so weight considerations and spoil removal are engineering issues to work on. So ..... anyone know how to build an economical vacuum tank?

Combine (relay?) multiple cellphone batteries for one large powerbank

I rarely trade my previous primary mobile devices when upgrading; as a result, my cache of obsolete phones with perfectly useable batteries is a dozen, give or take. I'm sure not many, if any, tinkerers, modders, hobbyists, etc., would recommend such a project, as these batteries can be unforgivably volatile if used any way other than their manufacturer's suggest, and sometimes even then. So let's assume we've all been warned; no need to reply "don't...". that being said, has anyone here ever attempted anything like this, or know, or heard of someone who has? if so, links would be much appreciated.fyi, i ask because i'm considering trying to mod an old rc car into a wifi/app controlled car, and repurposing as much of my neglected junk as i can to do this, would be soo satisfying.Thanks!

Designing a working Ranque-hilsch Vortex tube to be 3D printable or machinable on a lathe

I have looked far and wide in the attempt to fully understand how these tubes actually work.Nothing online really satisfies me fully so I made my own theories ;)I won't bother you with them tough as the foucs is on giving some tips on designing these tubes.Lets start with the main components as you find them in petents and some of the online videos and tutorials:1. The tube.It does not seem to do much but it is a very important part of the design.The diameter needs to be correct for the pressure and air flow rate so the up and down vortex can form properly on the inside.The lengh is important as well because you won't the hot end outlet right where the tube is hottest.Too long and you waste more than you use, too short and you won't get a decent temp difference.2. The chamber, rotation box, inlet box or whatever you wanna call the thick bit where the air goes in that holds all parts together.Most designs, even commercial ones, seem to go dirt simple here.Inlet on the side so the air starts spinning around on the inner wall.And that's about it as it really is nothing but a simple cylinder.However, the free space and internal design of the components affect the performance of this chamber.3. The engine, diffusor or cold end tube.This little gadget, in commercail tubes, serves a dual purpose.Firstly I provides small inlets to generate several vortex stream for the tube.Secondly I provides the cold end outlet nozzle.Both the nozzle and the inlets are important for the workings.Depending on their dimensions you need a higher or lower airflow and get a higher or lower temp difference.With just these three bits you see that a lot of variables are involved.I simulated most of my parts, but with the lack of proper software this happened in the empty void between my ears ;)Needless to say I learned a lot of ways to design fance looking tubes with no real function LOLIf you use some aluminium tubing for the actual tube and machined parts you have an advantage over 3D printed plastic parts.Not just in terms of safety but also in terms of actually measuring the temp of the tube.Blessed are those who have a heat vision camera :(Either way, once you start the design there will be a lot of errors you would need address later - and they waste time and material.Let me share my thoughts on how designed my first working tube:Compressor delivers a certain pressure and flow rate.I made something to test how different diameter holes as a substitude for tubes would affect the air pressure and flow.Once I had a diameter that would not drain the compressor and kept a stable pressure I used this to calculate inlet and orifice sizes.Goal was to have the same overall cut area as for what worked on the compressor test.For example if a 10mm hole works fine than a first guesstimate for 5 inlets would be a 2mm diameter.Usually slightly more as interal friction and such create more pressure in the system.So far for the inlets and vortex creating parts - what about clearances??Imagine you have a short cylindrical space where the tube shall be mounted to.Your inlets need to have enough free space to allow for the air to spin around the center.Key is to have the clearance tight enough to keep a high pressure in this area.Imagine the 5 2mm holes from the above example providing the air flow.A 1mm gap would mean insane pressures that most likely will limit performance.On the other side a 8mm gap will cause a massive pressure drop and results in the vortext from the inlets to get chaotic.Hint:If you blow compressed air through the housing with the engine inside but no tube mounted and just a backing plate to close it then you should hear a distinct sound.If it sounds just like air escaping through some holes you got it wrong :(However, if start screaming like mad when the pressure goes up it means you created a quite powerful vortex ;)But don't confuse the sound of small holes with something that almost sounds like a siren ;)A tube lenght of around 15cm seems to work fine for most applications.However it makes sense to check the tube temp to make sure the lenght is set to the hottest part of it.If in doubt, try it out ;)You designed it so well, it makes all the right noises but it won't cool or get hot....I had this problem a lot in my early days.An old patent however gave the clue that you won't find that easy.On the hot end outlet you can use a simple cone to limit what comes out of the tube.Either with fancy internal outlets or just outer casing with slots.Not much different to what you find online.What you might miss though is the diffusor or vortex terminator.You see, the upgoing vortex is extremely fast in it's rotation.If it hits the outlet cone like this then most of the air will be forced out and the inner vortex won't form at all.A star like insert at the end of the tube will cause the outer vortex to become a straight upward stream.Not all of the air will be able to fllow this route, so the rest is refected and creates the inner vortex.A tiny detail that often gets lost it seems.
