Some other key points about this project is that it uses reasonably cheap particle filters (intended for vacuum cleaners) and a fume filter as used in commercial solder fume extractors. They were cut using the same method as before (mark out the circular shape and then drill lots of small holes, cut out with a knife and then sand it into a circular shape).
The ones in DIY stores are not fantastic (in my opinion) for this, I prefer a small metalworking square. Are you a passionate writer? is a company that makes printed circuit boards (PCBs). This only applies if the same HEPA filter and fans are being used otherwise the values will need to be adjusted. (LogOut/
If you need a good soldering iron, then we've got you covered.
All Rights Reserved. The project is designed around the idea that a lot of electronics that is thrown out contains fans; examples include desktop PCs and servers. There is not a lot of wasted space between the fan and the power supply. You're all done! The repetitions will depend on the thickness of the sponge. The most common types of fume extractors are no more than an AC muffin fan with a piece of activated charcoal stuck on one side or the other.
There are two potentiometers here that are connected to the 5V and will act as voltage dividers. Can we hope have it released someday soon ? With such easy precision, it will all fit together well, not much harder than flat-pack furniture (I long for the day IKEA sell flat-pack soldering fume extractors).
Leg stuck in hole in pcb, cant melt out using everything Amazon Fire Stick 4K - redirect Micro USB help. I was thinking the very same thing! You can save $5 when you sign up through the link below, and you can save another $5 when you check out by entering the coupon code PCBWayLab. Even if you only solder things once in a while, it's a good idea to have a solder fume extractor nearby to suck in those toxic fumes and run them through a carbon filter to neutralize them.
If you don't have a 3D printer, read on and I'll share some ways you can get your model printed. The Aux connector is a mini DIN socket; it will be used for extending the functionality at a later date! One of those components is flux. The fan array will drop in from the right side of the tube, until it hits the Fan Ingress Surround. To begin, we will be declaring some variables and then assigning them to the pins that will be often used throughout the course of this project. Press J to jump to the feed. The input voltage is connected to a 7805 voltage regulator, which will turn the VIN into a steady 5V DC supply. The Ingress Plate needs to connect to the hose. Therefore, breathing in solder fumes is very, very bad. You can save $5 when you sign up through the link below, and you can save another $5 when you check out by entering the coupon code PCBWayLab. I have the files uploaded, If you like this project, share this with your friends and also like. Rosin is a serious occupational health hazard. Let's get started coding right away.
You should be able to upload your Gerber file and send it for review on the next screen. Making a DIY Soldering Fume Extractor with Lighting, ControlEverything.com 4-CHANNEL RELAY CONTROLLER FOR I2C, Home Automation with Arduino Uno and SmartEdge Agile, Soldering Iron Controller for Hakko 907 v.2. Pretty good response time to iosc 's request. Take the grill and glue the DC jack and the switch on it. With an Arduino, a PC fan, and an LED strip, you can make a simple fume extractor that will keep you safe from the fumes from soldering. I seriously think you are on to something. Connect the black wire from the jack to the negative terminal of the fan.
Take out the power supply and turn on the fume extractor. Premier Farnell Ltd, registered in England and Wales (no 00876412), registered office: Farnell House, Forge Lane, Leeds LS12 2NE. This is exactly the size you'll need. Press question mark to learn the rest of the keyboard shortcuts. Only the filter box and plenum are 3D printed parts. So, when soldering, it is very important to have enough light and a fume extractor to get rid of the smoke.
The enclosure is based on 4mm thick poplar plywood. There's an internal hole in the unit that's meant to run the fan cord through if you created your own fan circuit. Start by tracing the outline of the fan. Sandpaper can be wrapped around any convenient cylinder (I used a small round paint can) and then the wood can be sanded against it. Once the review is done, all you have to do is add the PCBs to your cart, pay for them, and wait for them to arrive. Just to explain the diagram, it is constructed like a tube, with an air ingress side and an egress side. The small pieces marked Support Block could be omitted, but are used for strength.
The Fan Support A/B pieces can now be glued into place, using the Support Blocks as needed. Filters A and B are vacuum cleaner spare parts therefore they will not be as good as the filters used in commercial solder fume extractors. Glue the second Side A piece into position (dont glue to the Ingress Plug), Remove the Ingress Plug assembly which was just clamped into position, Glue the Jig Piece long edge to the Jig End. To order a PCB from PCBWay, go to the PCBWay website and fill out the instant order form with the board's basic information. Simply turning the potentiometer allows us to control not only the level of brightness produced by the LED strip but also the rate at which the fan rotates. 4mm thick plywood (all dimensions in mm): 12x12mm Dowel (all dimensions are in mm): The Internal Fan Surround needs a 115.5mm diameter hole. :).
The filtering capability is in three parts; filter A is closest to the hose and is a basic thin sheet that filters large particles, followed by filter B which is a HEPA filter for small particles, followed by filter C which is a carbon filtercarbon filter for removing some gasses. The ingress side is on the left side of the diagram. Around the same time that I was developing firmware on Rev 2, the 3D printed parts and the laser cut acrylic arrived. This project sucks! I remember that solder and miss it. The flux itself is not activated until you apply heat, whereupon the flux will remove oxidation on the metal surfaces to be joined, allowing molten solder in the vicinity to attach to (a process known as wetting) the metal surfaces being connected. The cheapest micro soldering station in the world, using a cheap USB soldering iron. For the housing, we're going to use an excellent design created by rdmmkr on Thingiverse.
As mentioned after cutting it can be sanded for precise trimming if the wood is cut slightly too large; the wood is so soft that it takes just seconds to smooth out. The front panel holds together the front part of the housing and provides a spot for a small rocker switch (in case you decided to build your own fan circuit).
This means that gaps around the edges of the panels are minimal, and I did not have to grind or drill any new holes to get the fastener holes lined up. My activated sponge was large enough so I needed to cut into the required part. I printed the housing in white and filter housing in red to make it a bit more aesthetically pleasing. Note: This is part 1 of a two-part project. It seems to be fairly straightforward, doesn't it? The first time I soldered was also around the first time I could hold a pencil. I have a cheap desktop fume filter extractor on my bench (it has a particle filter of sorts) as I couldn't justify the cost or the space taken up by, Wooow that was fast !! To save time, I'm using a 5V fan with a switch and wire built in. All of the fasteners and corner brackets are off the shelf items from McMaster Carr. Pretty good response time to iosc 's request. The red wire will then be soldered onto the switch and from the switch, one more wire will connect to the other terminal of the switch and the positive terminal of the fan. element14 is the first online community specifically for engineers.
Part 2 will cover the rest of this project.
Test that the HEPA filter (Filter B) comfortably but snugly fits into the assembly, and hits the Filter Stop A/B pieces. It will drop into the tube from the left side until it hits the Filter Stop A/B pieces. To do this, find the centre of the the wood and then draw a circle of 115.5mm diameter using a compass.
The DC socket is a usual 2.1mm barrel connector socket for power. Anyway, for occasional home use, I think it could be worthwhile assembling such a device for maintaining your health while working. Cost could be saved by using a non-anti-static hose. It's an incredible software to do designing, 123D and SketchUp were good, but Fusion 360 changed the way of designing. In a desire to reduce solder fume gasses and particles inhalation, this project seeks to filter it all out using parts such as vacuum cleaner filters and PC fans.
The Egress Plug assembly was glued onto a Side B piece, The Ingress Plug was temporarily clamped into position (dont glue it, we will use it just as a support for now). Links to everything you'll need is in the parts list above.
How much of the smoke escapes through the back? It was an extremely tight squeeze, but everything did fit in.
Use two small screws to secure it in place. In this video, we'll make a soldering fume extractor out of an old PC fan and a 12V LED strip that can be used to change the light. There are a lot of pieces that need to be cut, so it is important to label each cut piece so it doesnt get confusing. I didnt see any smoke coming from the back, but it couldve been dispersed by the fan to make it harder to see. PCBWay is where I got PCB.
Breathing in lead is bad. After putting the new box to the test with a few smoke-heavy soldering and desoldering operations (VFD, binding post, and capacitor replacement on an eBay score Agilent E3648A power supply), the room did not stink nearly as much as it would have without my new fume extractor. Check out the link below if you want to make your own PCBs for your project. It is available as 3-ply. replacement capacity is significantly larger.
(LogOut/ Then factor in all the sweat equity for designing, physically assembling the prototype, and developing firmware. In a really good way!
Fortunately, the tolerances on the laser cut and 3D printed parts are very tight. At this point the Fan Internal Surround can be glued on two edges and fitted into the assembly. As an experiment I decided to see if it was possible to build one. I designed the whole model in Autodesk Fusion 360. It basically consists of a hose, some filters and some fanssome fans stacked up behind the filters. The enclosure is designed for an exact fit around the HEPA filter because that is the largest component. After the, It basically consists of a hose, some filters and, The hose is an anti-static one, to prevent static electricity build-up from particles in the air. Soldering is awesome, right?

After the last project that sucked, I hope this is the last one to do so for a while : ).
Change), You are commenting using your Facebook account. Remove the filter and fans, and glue on the final remaining side piece (Side B). Flux generates the visible fumes seen during soldering. The square is used to ensure the frame has perfect 90 degree angles. Put the leg in the desired height mount hole and fix it with the M4 nuts and bolts. I cut the cabinet with a dremel and then spray painted it. We're hiring!
These were designed to accommodate the Hakko C1571 duct kit and an off the shelf HEPA filter: Sears Kenmore EF-1, Part #86889. First assemble the four Egress Plug A/B pieces into a frame and gluing it, one joint at a time.
It came in convenient 300x210mm sized sheets as a pack of 10. and the sides were already very square, which makes accurate marking and cutting easier. I made a similar build, but used one of these, and a DC adapter instead of batteries. Not only it can be used for soldering, it can also be used for 3D Printing ABS, as its fumes are also toxic in nature.
I wanted to design a leg that could be easy to use and also the height could be easily changed. The Aux connector is a mini DIN socket; it will be used for extending the functionality at a later date! You can then turn the fan on and off using the controls on the fan's USB cable. The entire project is more an exercise in woodwork than in much electronics to be honest. Finally, use the four included fan screws to secure the fan and its grill to the housing. You have two options for your 80mm fan -- you can either solder your own fan circuit and add your own switch, or use one that's plug-and-play. I love making projects from scratch whenever possible, so soldering comes in the process, which should be done in a well-ventilated environment - unless you can use a Fume Extractor. This project cost around 5$ but works like a charm. Perhaps a speaker enclosure could be repurposed for the outer shell to save some effort. Next, using the Jig Piece/Jig End as a spacer, glue the two Filter Stop A pieces, and one of the Filter Stop B pieces. This is not a quick and low effort project; it is intended to a durable and high performance solution for effectively removing solder smoke while meeting all of the design goals as stated in the beginning of the article. PVA (wood) glue was used. Soldering needs to be done in a well-ventilated environment or a Fume Extractor should be used. Also, breathing in the fumes can cause long-term health problems, such as stomach problems, problems with memory and concentration, muscle and joint pain, and so on. By using standard sized fans intended for electronics/PC use, cost can be saved if you already have some handy.
The diagram here shows the measurements I used. Make sure the Fan Ingress Surround is also air-tight against the fans! Once the circuit was done and tested, I used Altium to design a small PCB where I could put all the parts in a neat way. Now time to test the fume extractor. I don't have any good quality photos but here is a low-quality one.
Ideally, I wanted a fume extractor with the following qualities: So what do you do when nothing on the market meets your demands? The filters should take out the toxins, but is the smell reduced as well? Pressure builds up (in this case a reduced pressure between the filters and the fan, since the fan is sucking through the filters and not blowing) to the point that the fan works so hard that air flow is greatly diminished. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Enter your email address to follow this blog and receive notifications of new posts by email. The Egress Frame A/B pieces are used to provide some thickness for attaching the Egress End Plate (not shown on the diagram). As the old adage goes, you get what you pay for. I shortened it. In order to use the compare capture modules (CCP) for both generating PWM to control the fan and counting the period of the fan tachometer input, I needed to alter the pinout of the fan connector. The photo here shows most of the main assembly complete; at this stage the insides are visible, before the final side is glued on top. :). It didnt occur to me at the time. Check out our guide on the best soldering irons for different tasks. We use cookies on our websites for a number of purposes, including analytics and performance, functionality and advertising. I came up with this design as final. Being that this my first time using PIC, I knew the learning curve was going to steep!
The downside is this fan has a lower CFM, meaning you'll need to keep it closer to what you're soldering. This is pretty much the whole circuit. I came up with this design as final.
This project is intended to greatly reduce the amount of fumes in the soldering iron vicinity, and the hope is that the particles are being captured in the filters and not being recirculated in the room, although I cannot currently confirm this. They included solder, and it had the best smelling flux. One of the Side A pieces can have all the holes for the connectors, LED and power switch. Firstly prepare the filter. If you like this project, share this with your friends and also like my Facebook page. Since flux is essential in achieving strong solder joints, there is no way around producing smoke when soldering. If you like this project do vote for it in the contest! It can be used as-is, or shortened. Change). A really elegant solution was found by luck; there is a, Open Source Hardware requires membership for participation - click to join. Explore Howchoo's most popular interests. How to make a DIY Rocket Launcher using Arduino - Design the circuit, make a rocket ignitor and control the launcher from your phone. To put it simply, it is easy! The HEPA filter (Filter B) was also checked for fit: The filter has a rubbery lip which mates with the side of the Filter Stop A/B pieces, creating a nice seal. The Howchoo team uses soldering irons all the time for projects like Gamepad Zero or our hacked Raspberry Pi keyboard. Change the information about your board on the PCB specification screen. Replaced the HDMI port on an Xbox One S. First attempt at Any tips to help soldering this 22 gauge wire to these Found this soldering iron. While the laser cut panels and 3D printed bits were on order, I began with fabbing up the first revision of the controller. The dimensions in the project leave very little space for the electronic connectors/components. I made the holes centred 26mm off the egress side edge. Beware this fan works in one direction only, so you need to solder it in the right way. Commercial solder fume extractors can cost upwards of $70.
Soldering is an essential practice in any makers repertoire.
Glue the Ingress Plug to the Ingress End Plate. I havent used it for a long time yet but the three times I used it for a quick connection it worked really well, I still noticed a bit of a smell but nowhere near without it.
Next, draw lines on the Side A/B pieces, where approximately the Fan Support Blocks are desired. Test that the four fans (taped together) comfortably but snugly fit into the assembly up to the Fan Internal Surround (see photo below). When combined with such dense filters fans have to work harder to force air through. I am super impressed. Howchoo is reader-supported. Want to support Howchoo?

So basically i am a crazy person, who loves to think the most odd way ever possible,who makes what he thinks and also let other also make those . Software engineer, designer, tinkerer, and beer enthusiast living in Tampa, Florida. The ones I ordered came with five filters, meaning you get a total of 20 filters after cutting. The activated carbon filters I ordered are 130x130x10mm. Why cant we have a machine that actually filters smoke, but isnt a huge metal box that rolls around on the floor?
The power supply is a Mean-Well RSP-150-12, which is a quality 12 volt AC-DC supply with plenty of overhead for the 62 watt rated fan. I had initially thought the fans could have been fine just pressed against the Fan Ingress Surround, but that's not the case. The diagram here shows the internal layout. The filter will be held in place firmly when the end plate, the Ingress Plate, is screwed on. So, the Arduino Nano is basically the brain of this project, but you can use any Arduino board.
Soft foam material could help, or just glue them together.
Connect the fan to a USB power supply (this is the one I used). Connect with your peers and get expert answers to your questions. The design intent is focused on keeping the box as compact as possible. Very nice! To my amaze, this fume extractor is monstrously sucking the fumes and, due to the activated carbon filter, everything is getting trapped in the filter. I did use carefully (syringe) applied JB weld to secure the mains power receptacle into place, as well as tacking the nuts for the top panel to the top four corner brackets (or else it would be impossible to put the last panel on and hold the nuts from inside the box!). If I ever need to open the box up for servicing, the top panel is the designated service entrance, as you can just barely squeeze your hand in from this direction to undo any connectors or nuts. Then, close the two halves of the main housing around the fan, ensuring that the fan is oriented correctlyto suck in air from the front and push the air out the back. With hindsight it could also be possible to use a bathroom fan or other fan intended for connecting to ducting within a building. When you have all the parts and the PCB, you can solder them together. However, I have only recently (almost two decades later), learned how to solder properly. My design began around a fan and power supply combination I already had in my parts bin. When assembling it, one important step is to ensure that the Fan Ingress Surround is air-tight when glued to the sides. For this project, we'll be using an amazing 3D-printable model designed by rdmmkr on Thingiverse (thanks, rdmmkr!)
This will also hold the back part of the housing shut. Ive given it the nose test, with the stinkiest flux that I own; provided the iron is close to the end of the hose, the smoke gets sucked up and I smell nothing until the iron is moved away. A few lengths of square section wood (preferably hardwood) dowel is also needed; I used 12x12mm section. The outputs of the pots are connected to analog pins A0 and A1 respectively. Thank you so much, great work. I opted to do this since this is the very first physical manifestation of this project, and did not want to scrap the entire thing if I needed to make a change. Not bad. It's fun to make our own PCB for our project, but there are a few things we need to watch out for as we solder the parts on. The panels are laser cut 5mm thick acrylic. (LogOut/
If you'd like to solder your own fan circuit instead of using a USB fan, see the instructions on Instructables.
Most of my parts are salvaged, I highly encourage people to salvage and recycle but if someone wants I have all the item listed below. With a knife or small jigsaw, the centre can be cut out. Inspired by the simplicity and ease of use of the DIY Weller station project I built earlier, I designed my own board using the same PIC16F1788, with the intention of being able to generate PWM to control the fan and also display the fan speed in RPM. Exposure to this rosin can cause eye, throat and lung irritation, nose bleeds and headaches. Of course, this style of extractor is usually equipped with several stages of filtration down to the submicron level, meaning it does a good job of actually capturing smoke and the pollutants you want to avoid breathing. From there, you'll be taken to a form where you can give more information about your board. Also, soldering parts onto the circuit board is hard on your eyes, and doing it in low light can eventually damage your eyesight permanently. You whip open your favorite CAD program and get to work on a new design! There are many styles of smoke extractor, each with its own tradeoff between physical size, filtering performance, and overall handiness when setting up and using.
