Electrical schematic help/wiring + arduino programming

Hello,first time user here, so i would like to just apologize for the wall of text that's coming up.Im trying to build this little enclosure here https://www.instructables.com/id/Touch-sensitive-... and i have a hard time understanding the basics of the electronic schematic thats invovled, when he shows how to build it. Nor do i truly understand what components are in it, hence why i cannot determine the price of this build (based on electronics). So i was wondering if anyone could lable one component by one for me, aswell as how to connect them all together? so that i could calculate the pricing and see how much it would actually cost. Seccond thing is that i wanted to change it up a bit, and use neopixels, or ws2812b led strips instead with a teensy 3.2 and fastled library code, for that fiery effect. Thought that might look really cool. However im concerned with the power draw of these ws2812b led strips. Getting information from adafruit: 60mah per led at maximum brightness, but thats eye blinding, so a 20mah per led is more logical, as someone with neopixels wouldnt be running full white anyways, and more colorful setup, or patterns. Im able to get 144 led/m quite cheap, but then the power draw of just 1m is a whopping 8.64 A. Which is starting to sound pretty dangerous at 5v. But then again, im not buying neopixels to run at full white brightness, i want the patterns. Im wondering if there is any possibilites to make a admin command or a priority list or something to lower the brightness of the strip entirely without messing up the code? i know regular leds have ir remotes to dim the light. I mainly just want the red flame effect, which is only 20mah at max brightness and a peacefull 2.88 A, but i also want white light + i want the safety of knowing i can supply the strip of the power it needs, just incase. The video with the code is underneath: (code in video desc)and i know 144 leds/m is probably overkill, but then again, im getting them dirt cheap, + it would give off a much better fiery effect than a 60 leds/m or even a 30 leds/m thanks in advance for any replies, and sorry for my wall of text. :)

How to combine 2 audio signals from HDMI

As I've known so far there aren't receivers that mix audio.I want to mix 2 HDMI sources, lets say 1 is a PS4 and second is Xbox One, how would I mix them in 7.1? Mix the 2 audio sources into 1, is there a way of doing that? What is the simplest way.I know that there are stereo mixers, but haven't heard of a HDMI one.What is the simplest way of mixing both signals?I think it might have something to do with modulating the signals, but I dont specifically know how modulators work.

The save button in deactivated in Acura 15.04.6

I am trying to export a G-Code from Acura I noticed when I loaded the file, starts processing and at some point it stops. I can see the support material did not finish processing and the top portion is not complete.Then I make changes to the settings I increased the height of the layer and reduced the density.In other words is a lighter density overall. If i decrease this a lot, Then the software manages to finish the set up proces and the save button comback active to export Gcode.Seems like the large data of the higer density settings runs out of Disk space to create the cash.Does anyone know how can I fix this problem?I remember when I work in Adobe after effects editing videos, the software ask me to reserve a dedicated folder with an specific disk space just for cash, when this folder is full, the software ask you to empty the temporary cash files to make more disk space for more projects.Does anyone know how i fix the space disk or what ever i need to do to allow the software to finish procesing with higher density?Please helpYou can email me to gamelicruz@gmail.comThanks

Need a table top that can push stuff upp in the air

Okay so i need some help with a prop for a photographing stuff in mid air.I need a device (flat surface) that I can place objects on and it will shoot them up in the air.Imagine a bowl of popcorn or a pair of glasses with water in them flying up in the air etc. I will then have sensors that will trigger the camera at the right time. (these devices and system I already have)My dream would be to be able to control this "jump table" device thru a simple solenoid valve. (12v) So my rough plan is to have to sheets of wood 40cmx50cm about 1cm thick.Next is to have a pneumatic cylinder in between these two that will push the top plate up and down.I probably need some sort of guides in the corners of the plates so it moves correctly.The pneumatic cylinder will be controlled by a solenoid valve, the solenoid valve i hope to turn on/off with a 12v power supply. The easiest solution for air source would be a co2 cartridge.But if that's to much pressure for the components maybe a cheaper air compressor in a smaller size is usable ?So what im looking for in general advice in terms of pressure and pneumatic cylinders, which i do not have any experience with.This video pretty much has the basic components i need i guess ?Any general advice what to look out for when choosing components and air source ?Thank you!

Tips or products you recommend for clearing or preventing ice in winter?

My partner and I just bought a house and we're doing some repairs and upgrades. One of the major things I want to focus on is making our front entrance less icy. Most of the time we're covered in snow, but whenever it warms up briefly we end up with an icy disaster on the front porch the next morning. :P Currently, the roof melt runs right off onto our front steps and it's a mess! (see picture for the icicle death trap)I have been using a "pet-safe" ice melt (we have two dogs who are in and out all day) but it doesn't do enough for how much I go through. I still break up the ice in the morning when using the ice melt because the ice builds up really quickly.Are there gutters strong enough to handle heavy snowfall? Some sort of heating element I could install? For reference, I'm in northern CO in the mountains and we tend to get feet of snowfall every winter! I've never lived somewhere with this much snow, but I'm hoping some of you do and can offer some suggestions :D

HP, Lenovo, ... Laptop Bios update boot loop fix

I had to install Windows on an older HP laptop today.And being the nice guy I also updated the Bios to the latest available.Now these Windows tools for this job are great fun, start it, press a few buttons and all is updated.Well, until you realise the thing ends in a constant bootloop going back to the bios update part created on the recovery/backup partition.Going the official way by asking the support is pretty much useless as my searches only came up with copy and paste answers but no solution.Some people got desperate enough to order a new bios chip, program it and solder it in :(But the fix is sooo easy and obvious that it might take a little kick to realise it ;)I assume you downloaded the right tool and bios update.For HP and Lenovo it all comes in one pack anyway.I also assume the tool stated that all went fine and the backup and update were done correctly.Now the boot loop that you experience is actually on purpose ;)You are required to enter the bios - for my HP it is the ESC key, then F10.Here you load the defaults, then adjust what you need - like the boot order.Once you set the boot order to the internal HDD or the OS boot manager you are good to again.I hope that will help the desperate people that got nowhere by trying the support for their laptop ;)

10 Best Electronics Suppliers

First off, I would like to give notice to Electronics Projects for Dummies for most of this info.I wanted to make a site with many of the best sites to buy Electrical Parts, because it can sometimes be a strenuous activity. I have 10 here, because if you can't find something on one online store, you might be able to find it on the next.Reynolds ElectronicsReynolds Electronics is a good supplier of remote control components, micro controllers, and robot kits and parts. One feature that stands out on Reynolds Web site is the clear and helpful project/circuit tutorials. You can also find links for educational books on topics such as robotics and microcontrollers.Hobby EngineeringHobby Engineering is a sit slanted towards the hobbyist. This site carries some useful items that can be harder to find from other providers who are catered towards the corporate customer. it also has a good supply of micro-controllers, robot kits, parts, ad miscellaneous components and tools.All ElectronicsAll Electronics has an incredible selection of many of the useful items you would use to build your project. They are very inexpensive and it is easy to find your way around the site. This site also has a "consumer comments" section where the consumers get to talk about the quality of the product and more. (Thank you westfw)BG MicroBG Micro is a cool site for rare and pretty neat gadgets as well as a nice selection of alot of the items one will need for a weekend project. There is also a very nice search engine at the top which lets you search for an item you can't find on the left. (Thank you Las Vegas)Jameco ElectronicsJameco has a very nice site catalog. It's not very big that you sspect a forest was sacrificed in its making. I has great color photos with relatively easy to find components. This is one supplier wih a low price fuarantee which means that if you can show a part offered for less, the lesser price is honored. jameco also provides lower priced generic products as well as name brands.DigiKeyDigi-Key is a large distrbutor of components from various manufacturers, offering a very large catalog with lots and lots of choices. However, the site uses small print that might be hard to ead. The catalog includes line drawings but o part photos, but it does do an excellant job of labeling the parts. Overall, Digi-Key has a huge selection of products, but they might need a little looking to find them.loading...Mouser ElectronicsMouser ElectronicsAnother large distributor of components from various manufacturers is Mouser. I like how Mouser's site allows you to compile separate orders for different projects. You can come backa s many times as you like to complete your order and make your purchase. We also like how Mouser label parts because the labels are easy to read and provide alot of information about the specific part.Like Digi-Key, Mouser provides a very large catalog.RadioshackRadioshackEveryone knows Radioshack!. This electronics convenience store is pretty much like any food convenience store: CONVENIENT BUT EXPENSIVE. If you are stuck at 4:30 on a Sunday afteroon needing a small part to keep working on your project, this store is right for you. Be aware that not all radioshack are equal.Fry's ElectronicsFry's ElectronicsFry's has stores in nine states, and if you are lucky enough to live near one you can browse the isles in person. Fry's stocks all kinds of electronics and parts including an EXCELLANT selection of IC chips.Goldmine ElectronicsGoldmine ElectronicsIf you are in the market for bargains, try Electronic Goldmine.. This online store often offers sepcials that can save you money. Based in Scottsdale, Arizona, Electronics Goldmine offers great help with international orders and also offers wholesale items on auction on eBay.Quick Tip: Try clicking Electronic Goldmine Treasure Ball for the best deals!FuturlecFuturelec offers a very nicely done site with color photos of the parts that makes for easy browsin. Futurelec also offers semicnductor news links and also links to recently added parts to help you keep on the top of the latest and greatest as well as PCB design and manufacturing services.[htpp://maplin.co.uk Maplin]MaplinThe British suppplier Maplin has stores scattered around the U.K. and also offers an online store.Unlike electronic gadgets and appliances that operate on different voltages in European contries, electornic components are pretty standard. Although Maplin will ship overseas, you might want to check out U.S. Suppliers first.SparkfunSparkfun was originally a PCB Manufacturer, and turned in to a company well beyond their expectations! They have a large variety of PCBs, LEDs, and MANY more everyday electronics components. The site is well organized with so much to choose from!

Has anyone made a solar heat powered Fluidyne stirling engine air pump?

So, I will start with what I have in mind.  (Might be total rubbish because I don't fully understand).  You have a solar collector box, not more than 1 meter square.  painted black 1 to 2 cm deep,   and probably with glazing over top. The box itself is metal fully closed up and the back is insulated.  From the box through the insulation there are some metal tubes that go to another box at back for the cooling chamber. Tubes are constricted so the air sprays through to the cooling box and it goes into steel wool as it expands. On the reverse stroke, it does not go so much through the steel wool because the nozel constriction is  on that side not the hot side.   Power is taken away from a liquid piston somewhere attached to both chambers  or a diaphragm at the back. (It can be water cooled). I want the strokes to be long and slow. Can it work?   Temp difference will only be around 40 degrees C and the pumped air ( 2 valves  in chamber off of liquid piston) only needs to go to 2 psi. )    I have been in contact with a guy in Germany who made Sterlings that worked with sun heat.    But he didn't use Fluidyne (also called liquid piston stirling) and he did not pump air.          My specs are extremely low, I only need 60 litres per hour of air at 1 or 2 PSI.  It would be very cool to make it from such basic materials.                 Thanks Brian

What is your glue preference for 3D prints

I'm curious to find out what glue people prefer to use with 3D prints, why, and how you use it to get the best results. Here is what I've tried and how it has gone for me. E6000 - good glue, kind of messy and takes time to dry. I usually squeeze some out on some wax paper and use a toothpick to apply it. Weld-On 4 Acrylic Adhesive - very liquid, have to transfer to a bottle to use, which for me requires a dropper, dries super duper fast so make sure it's in the right place when you push pieces together, can leave a white residue if it dries on your piece. SCIGRIP 16 10315 Acrylic Cement - pretty liquid, dries fast as soon as it touches plastic, I had to buy an applicator bottle to use with it and it doesn't work so I'm not sure if I need a different bottle or it doesn't work well with a bottle. not really usable for me right now unless I can figure out what to use with it. So when I have used it, I squeeze some out and use a toothpick to apply it but it dries as soon as I pour it out. I've also tried misc super glues but they tend to leave white residue for me. Currently, I would say the Weld-On is my go-to for gluing 3D prints, but I'd love to get other people's opinions!

Cultivating blackberries - works for roses too!

Although in many regions (wild) blackberries are considered to be a pest, in our gardens they can be delicious.I don't mean the wild variety here but the cultivated ones with big fruits and no thorns on them.And if you ever tried to successfully save money by just buying one and using cuttings from it for the new season you know the troubles....Creating cuttings from blackberries is quite easy if done the right way.But there is an ever easier and simpler way if you don't mind doing your pruning a bit later than usual.Once the harvest season is over and all berries are gone you see that the blackberries still keep growing before they finally start dropping their leaves.And if all went well then your blackberries have grown in long "snakes" supported on a vertical structure - like long bows.During a good season this bows get so long that they almost reach the ground at the end of the season.All you have to do it to free your snkes so you can places their ends into the ground, preferably out to the side so you can start a new row of blackberries with enough space between them.Use some soft cord and weights to keep the ends in the ground and fill the hole.Only water once when done otherwise let nature take care of things.In a very dry climate or season you might want to water a bit once a week though.When leaves start to drop in big numbers cut the above ground bits off with about 10 to 15cm left standing.Prune the big ones as you always do to get them ready for the next season.And when the next season starts you will see that most of your little "cuttings" take off like mad.They had the mother plant until it was time to go dormant, so no extra energy was required to stop a dying cutting from going dry.The end of the plant realised it is under ground and for that reason it is time to grow roots.Then suddenly it is time to hibernate and all energy is left in the remains, ready for use in the next spring.It is no problem to get over 15 new plants from a single one this way for the next season.It also works quite well fo roses.Although here you might need to create a podest or similar to place pot on.And the season for it is different too ;)It all starts with your pruning at thend of the season.All parts that did not produce flowers, those "wild" stems need to be fully removed.Those who produced good are cut back so you are left with 3 to 5 "eyes" - these tiny pimple where the new shoots come out.Pay attention to their location as it determines the direction of the new shoots ;)Don't have too many facing inwards.When the rose starts growing again in spring you should prepare your stand for the pot.The new shoots are quite flexible and can be directed to grow where you need them for the pot by using bonsai tape or wire - just be gently with them!Once long enough that the end can be placed about 5cm deep into your pot with good potting mix or the good soil from your garden:Place the pot so that the end shoot is held in the soilwithout force - if in doubt let the shoot grow a bit longer and form it donwards with wire.You want to bury it only when there is new growth going out if it but not of the end currently only has the leaf(s) showing.These fresh end shoots should point downwards into the soil.Cover it all and keep the soild moist at all times but not soaking wet.It really helps to have the pot shaded.You can use small seedling pots and check for roots a few weeks later or just wait till the end of the season.Either way a root should form in the pot and once strong enough you only have to wait and look out for eyes forming on the stem.If the do you can cut the stem so you have enough eyes on the potted stem.Be aware though that this will only result in a strong and healthy rose if the mother plant is not a hybridised clone.For the later it is best to transplant and eye onto a donor bush or wild rose.

Quirky tip on how to propagate roses?

Recently I found this little quirky tip on how to propagate roses/ bushes and I was wondering if it was true? In the little tidbit, they tell you to use a cutting of a rose of course and then put a little cinnamon on one of the ends that you intend to grow roots. Then poke that end in to a potato. Then bury that part with the potato into the ground. After I guess eventually you get a new rose bush. I was wondering can this actually work? Or is this just bait to get you to read more of their articles?

Ideally i want to slice one trunk into coasters/trivets, keeping the exterior bark intact. The other trunk might become the base for a side table or something similar. Or maybe I'll just hollow it out like a cup and use it as a pencil holder. Thanks for your help! Josh

Please Help for AutoLevel TronxyX5S

Hi, I apologize for the corrupt English first.I have a Tronxy X5S 3d printer. And I bought a sensor( SN04-N NPN) to add autolevel property to the printer. I thought I would be able to get rid of the small curves on the hotbed. I've arranged my commands according to autolevel as follows. But when I want to print a large shape, the extruder remains in the air at some points of the hotbed, print properly at some points, and at some points worth the hotbed(no filament output). So the autolevel property is not working properly. Can you help me?

Problem with too much window condensation

I have double pane, insulating glass house windows that collect condensation during the winter heating months. The condensation is not between the panes, it is inside the home. The water builds up and runs down onto the wood frame causing rot. It occurs only on the bottom inch or two of the window. The home is in Northern Wisconsin where it is commonly 20 deg F outside and 70 deg F inside. The interior humidity is controlled and not excessive. Aside from setting the interior humidity to desert-like conditions, how can I remove the moisture and prevent further damage to the frame? Desiccant bags? Solar powered fans?

Any ideas on how to create solid roof for steel framed gazebo?

Have one of those $180 steel framed, 10 x 10, two tier roof, gazebos that every retailer seems to sell now a days. (kind of like the one in the picture) Its perm attached over our hot tub. Problem is, the nylon top keeps deteriorating and then shreds and has to be replaced. Any ideas on a good, cheap or maybe recycled material, roof that would be permanent? (WI=Snow in winter, has to be strong enough for an occassional storm) And how to attach it maybe? Looking for a few brainstormed ideas because all I can think of is boring PLYWOOD! *GRIN*

How do I make a power indicater light for a bluetooth?

I have Bluetooth headphones, & I'm modifying them. I want my Bluetooth to light up tow external LEDs when I turn the device on. I can't wire a line to the micro LED, its to small for me to solder. I was thinking wiring the External LEDs to the Bluetooth's battery. Is there a way to make a simple connection from the battery, to the external LED wire & back to the circuit board, so when ever the Bluetooth is switched on, all the external LED is indicating is the power going to the circuit board?

Mariko Kusumoto

I have been trying to create color stripes in the same manner as Mariko Kusumoto. Cotton and silk thread have not worked. I think I need a different tool to apply polyester dye or different thread. The second image is messy but it was to test the strength of the dye on the bubbles. I think my problem now is how to draw the lines using polyester dye before steaming.

For those of you who have time off over the holidays, what will you be working on?I have 3D printing and laser cut jewelry ideas I want to work on both for Instructables and Etsy while I (hopefully) have some time and I was curious if people had plans for projects they wanted to try to get done.

Using a hall effect sensor with TL494 pulse width modulator.

I have an electric billy cart with a dead controller board. I constructed the kit circuit below to replace the dead board and it works well enough for the job except for one small problem. The throttle on the billy cart utilizes a hall effect device and not a pot. The billy cart also has a handbrake with a switch that closes when applied. I use this with a resistor to discharge C2 and pull pin 4 (inhibit) high. This ensures a gentle start (as the capacitor slowly charges through the 100k resistor) if the brake is released with the throttle advanced. The output range of the throttle is 950 mV to 4.1 V if VREF (5V) is used as the supply. (I'm dropping it in in place of the pot.) 4.1 V is sufficient to achieve the maximum 90% duty cycle of the chip, but 950 mV leaves me with a minimum duty cycle of about 21%, and of course a motor that won't stop. Will changing the divider ratios 20k/2k2 & 47k/47k be sufficient to get me zero speed or am I going to have to do something more exotic? Thanks in advance.

Soundproof Sleeping Closure

Hello fellow instructables :) Right I need some help and advice on a design brief to help fix my problem. Problem - I live in a ground floor flat and there is 1 flat above me, 2 scum bags occupy it, a couple of 22 year olds and they have obviously never been taught consideration for others and they bang and thrash around all through the early hours of the morning. When they bang on their bare wooden floor it sounds like a heavy metal dumbbell coming through my ceiling and it wakes me abruptly and its ruining my life :( I've complained to the council the past 18 months but there not interested. They have not put any carpet down in their flat in the last 18 months and it looks like they have no intention of doing so (they can afford fags n booze tho), plus they have a baby due any day now, great.. so now there making their problems, my problem. Solution - The only thing I can think of is making a soundproof sleeping closure, a large box like a 4 poster bed but all sides solid made out of a layer of MDF then insulation then more mdf, but I have some questions before I start. How would I get adequate air in and out ? Would this even stop the banging on my ceiling waking me up ? or would it still penetrate the box ? How would I control the temperature, would it be too hot in there ? Something like the image below but more solid with a door. If anyone has any experience with this or input or any good ideas I'd be ever so grateful. Cheers in advance. Matt

The future of mobile operating system or the end for "hackers" and rooting?

For mayn years it was almost logical to get full root access on your new smartphone or tablet.The other fraction might now it as "jailbreaking"...No one really needs it unless they are not happy with they way the mnufacturer designed the operating system and features.The removal of bloat, apps the user never needs, is still the most common reason for rooting.Custom ROM's offering a different experience are right behind.Now we also have TV's, entertainment boxes of all kinds, even from our ISP's directly.The main provider for the operating system is now Google with only a few "competitors" left.Apple has a strong hold of the mobile and tablet sector too but is not really presented in other areas.Android is still open source but Google heavily modifed it to suit the needs of data collecting and security for features like banking, access control and so on.What is good for the normal user and perfect for those with security in mind can be really bad for those actually just using a device.No matter why you buy a new phone from your provider, you almost never buy it for the added apps and services.Rooting has become more and more difficult.One reason of course is constant security updates and removing possible access options for even simple things like getting USB debugging and an unlocked bootloader.People dedicated to find ways to remove provider locks, creating custom firmwares or the basic tools required to work with firmwares were called hackers.If you buy a new car and decide to modify it with a new engine, seats or whatever than no one will stop you.So why don't we have the same rights for our electronic companions?I wouldn't call it hacking, I would call it actually owning and controlling your device instead of Google letting control you - or Apple, but who cares....The other reason is dead simple: Those guys who started it all have retired or found employoment with those they fooled for so many years.Chainfire should ring a bell for anyone ever concerned with rooting.The master is gone now and only a few people are willing to take his legacy.For Asian devices the community over there is better off but for our market region right now Magisk seems to be the only option left for modern devices.The sneaky ways to lock us out....Security comes at a price, simple as.You can offer secrity for money transfers if the device is not trustworthy.Same for online streaming - you want the money for what you give and prevent that someone is able to make unwanted recordings without encryption.The list goes on with access control system and literally everything we use our devices for that involves some security.Even with the lates PIE systems Google's own devices are still quite friendly in terms of gaining root access.Different story though if a manufacturer makes full use of all the latest addition at Google's disposal.Device security no longer starts with the boot we see.It is now possible to create a hardware based tree of trust.This means any modification to anything will cause a failure.This locks out all "tools" able to read out partitions and vital data while a device is in fastboot mode.And of course said fastboot can be fully disabled as well now.For security reason a so called A/B configuration is used.Updates come over the air and are applied to the dormant system.Next start will boot the new system and then update the old one, no requirement to manually apply and update.The recovery can also be abandoned and replaced by a system using a copy on the device itself that is updated through OTA updates with the firmware.So both ways to gain official access can be full removed from the user.From there we get encryption, hash checks and literally everything working in its own user space - a full SELinux enviroment at the highest level.There are already devices utilising a lot of this and so far the only way to get any sort of insight was done by those intercepting OTA updates on a router level.And apart from quickly changing the encryption with the next updates nothing was gained.Is it all coincidence?Of course not.Well known leaks were kept open for years.Kernel updates gave improvements and closed really old leaks but never all known ways.With the retirement of the best rooting experts these holes were suddenly closed.Checks of latest kernel releases showed that there is no known vulenerabilities anymore that can be misused to gain access.And those finding new ones and making them available for us are bascally gone now.Encryptions and packing algorithms changed, same thing for the actual handling of partitions and rights.Anyone with a decent understanding of how the old ways worked will be able to figure it out with some time wasted on it.From there however the outcome is often dark.The tools needed to work with these new files are not always updated anymore.The developer simply moved on and most of the time without publishing his source codes.And the still best way to protect your firmware from tampering is to encrypt it.In the old days it was enough to sign a ZIP file with a release key not available to the public.Custom recoveries allowed us to get around this.This still works to some extent but now we also get additional checks starting from the bootloader.A modified system will be detected and stopped and a stock system will stop i a modified boot is detected.Even using a custom recovery by flashing or through fastboot is preventable now.Right now the only way for most new devices is a total wipe and the installation of an unsecure firmware with everything.As you already guessed this is to prevent now as well.So does all this rooting stuff actually concern you?Of course not!If you never had any need for rooting or no clue what to do differently with a rooted device than you are a happy camper.But your neighbour or friend might think differently.You see, I have two problems when it comes to "stock" devices.a) I have no clue what data they collect from me and what it might be used for.b) I do not like being forced to agree to terms that are endless and of questionable content just to use the damn thing.For crying out loud: In most cases it is now impossible to even set up a new device without working internet and a Google account.....
