soldering fume extractor diy

Put the leg in the desired height mount hole and fix it with the M4 nuts and bolts. These were designed to accommodate the Hakko C1571 duct kit and an off the shelf HEPA filter: Sears Kenmore EF-1, Part #86889.

You should be able to upload your Gerber file and send it for review on the next screen.

Soldering needs to be done in a well-ventilated environment or a Fume Extractor should be used. The diagram here shows the measurements I used. For the second part, see here: Building a Low Cost Solder Fume Extractor - Part 2, Im sure Ive created some really stinky projects, but this isnt one of them. Download the model from Thingiverse and print the five main parts of the model: No supports are necessary. 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.

There's an internal hole in the unit that's meant to run the fan cord through if you created your own fan circuit. Just to explain the diagram, it is constructed like a tube, with an air ingress side and an egress side. I used a syringe to apply a small amount of neutral cure Dow 737 silicone around the edges to get an airtight seal. It basically consists of a hose, some filters and some fanssome fans stacked up behind the filters. My thanks to Jaakko, the designer of the DIY Weller station, for his support in helping me to solve fundamental firmware challenges I had when getting started. The Earth connection is made with a 4mm banana socket. While the laser cut panels and 3D printed bits were on order, I began with fabbing up the first revision of the controller.

It was an extremely tight squeeze, but everything did fit in.

To do this, simply use a bit of electrical tape or hot glue. The downside is this fan has a lower CFM, meaning you'll need to keep it closer to what you're soldering. Hopefully you get a kick out of it! We've put together a guide to help you find the best soldering iron for your next project. When you have all the parts and the PCB, you can solder them together. To do this, find the centre of the the wood and then draw a circle of 115.5mm diameter using a compass. I used four fans.

And here you can see an LM 741 comparator IC, which can be used to power any other devices you want. This is pretty much the whole circuit. The ones in DIY stores are not fantastic (in my opinion) for this, I prefer a small metalworking square. The dimensions in the project leave very little space for the electronic connectors/components. This project is comprised of three primary components: a 3D-printed housing, a fan, and an activated carbon filter.

Links to everything you'll need is in the parts list above. 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. Since the fans are smaller than the tube, they are centred inside the tube using the Fan Support A/B pieces.

To save time, I'm using a 5V fan with a switch and wire built in. Take the grill and glue the DC jack and the switch on it. The result was better than expected with about 5 minutes of sanding. The Fan Support A/B pieces can now be glued into place, using the Support Blocks as needed. Soldering is awesome, right? If you need a good soldering iron, then we've got you covered. I made a similar build, but used one of these, and a DC adapter instead of batteries. Think of it like a 2D printer, but with an extra dimension. There is not a lot of wasted space between the fan and the power supply. 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. Better to glue them. If you like this project, share this with your friends and also like my Facebook page. It can be used as-is, or shortened. With hindsight it could also be possible to use a bathroom fan or other fan intended for connecting to ducting within a building. The 3D printed filter box and plenum were the priciest parts, followed by the Hakko C1571 duct kit, the San Ace 9LG fan, laser cut acrylic panels, all fasteners, corner brackets and other metalwork, and the electrical components. Soldering is an essential practice in any makers repertoire. 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. Filters A and B are quite dense whereas Filter C is like a very aerated sponge and you can see through it. I have the files uploaded, If you like this project, share this with your friends and also like. When combined with such dense filters fans have to work harder to force air through. 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. Part 2 will cover the rest of this project. 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. This is exactly the size you'll need. The entire unit is powered from an external 12V mains to DC converter. A square is mandatory for this project, because some accuracy is needed for the cut pieces. Also, soldering parts onto the circuit board is hard on your eyes, and doing it in low light can eventually damage your eyesight permanently. We're hiring! This is how the PCB looks after the soldering is done.

(LogOut/ As the old adage goes, you get what you pay for. In the following line, we are going to turn on and off the MOSFETs that are connected to the Arduino Pins 9 and 10. If you prefer a higher CFM fan, you can find one on Amazon, though you may need to bump up to a 12V fan to get a really high CFM. Place a filter into the cartridge and slide it into place. 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. While I was designing Rev 2, I also opted to add a relay for turning the fan power on and off; some PWM fans will turn off at low duty cycle, but others do not. Fan suction will hold the tape in place tightly. Not bad. Pretty good response time to iosc 's request. holes just inside the circle.

Connect with your peers and get expert answers to your questions. Being that this my first time using PIC, I knew the learning curve was going to steep! I'm very interested by your project but it seems like you never released part 2 - am I right ? Of course, the information and files provided are for recreational (non-commercial) use only; no guarantees are expressed or implied. 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. 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. If you don't have a 3D printer, read on and I'll share some ways you can get your model printed. 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. 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. (LogOut/ If youre interested, click on the Bookmark link for a reminder for Part 2, which will follow shortly!

The design was created such that the filters and the fans are removable for servicing by unscrewing the respective end plates of the tube. In a more professional setting (and where labor laws are actually observed), solder fume extractors are large boxes positioned on the floor, with ducts running up to the operators work area. Change), You are commenting using your Twitter account.

By using standard sized fans intended for electronics/PC use, cost can be saved if you already have some handy. The Ingress Plate needs a 27mm diameter hole (to suit the hose) and the Egress Plate needs a 125mm diameter hole. It will involve painting the wood enclosure, and adding in the wiring, final assembly and then testing it out! I chose to position them centered, 80mm apart. The dowel assembly will be glued onto the end piece, and will be screwed to the main assembly from the sides. It will drop into the tube from the left side until it hits the Filter Stop A/B pieces. The cheapest micro soldering station in the world, using a cheap USB soldering iron. Combine that with the cost of good soldering irons, and you're looking at some expense. Most filters come in a large size, so you need to cut it into the desired size.

Sure, the fan might pull fumes away initially, but that scrawny piece of activated charcoal doesnt do much in terms of actually removing the smoke particles from the air. Connect the fan to a USB power supply (this is the one I used). If I had to guesstimate the bill to buy and replicate this fume extractor, the total would be between $500-700 USD in raw materials alone. Connect the black wire from the jack to the negative terminal of the fan. and fill out the instant order form with the board's basic information. Pretty good response time to iosc 's request. Today, I'll show you how to build your own for about $20. How much of the smoke escapes through the back? how to get your 3D model printed without owning a printer, The removable filter cartridge front half. 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. The outputs of the pots are connected to analog pins A0 and A1 respectively.

The Aux connector is a mini DIN socket; it will be used for extending the functionality at a later date!

fume extractor solder instructables If you like this project do vote for it in the contest! The design intent is focused on keeping the box as compact as possible. 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 !! Commercial solder fume extractors can cost upwards of $70. They specialize in PCB prototyping, low-volume production, and clean PCB assembly.

Only the filter box and plenum are 3D printed parts. The Best Soldering Irons: Read This Before You Invest (2022). So, the Arduino Nano is basically the brain of this project, but you can use any Arduino board. Check out the link below if you want to make your own PCBs for your project. Therefore, breathing in solder fumes is very, very bad. is a company that makes printed circuit boards (PCBs).

I had initially thought the fans could have been fine just pressed against the Fan Ingress Surround, but that's not the case. Improved version of the soldering iron controller for Hakko 907 iron. Repeated exposure can cause respiratory and skin sensitization, causing and aggravating asthma. Put all the parts on the board by soldering them on, and make sure to check the polarity of the parts. I came up with this design as final. The Egress Frame A/B pieces are used to provide some thickness for attaching the Egress End Plate (not shown on the diagram). If you don't have any small screws laying around, you can also use super glue or epoxy to hold everything together.

To do this, we are going to output PWM signals with values that were generated from the lines that came before them. The fan is a San Ace 9LG1412P5G001, which is a 140x51mm axial fan with a max airflow of 318 CFM. All of the fasteners and corner brackets are off the shelf items from McMaster Carr. Sandpaper can be wrapped around any convenient cylinder (I used a small round paint can) and then the wood can be sanded against it. 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. For the housing, we're going to use an excellent design created by rdmmkr on Thingiverse. When you buy a tool or material through one of our Amazon links, we earn a small commission as an Amazon Associate.

PCBWay is a company that makes printed circuit boards (PCBs).

Note: This is part 1 of a two-part project. Filter C is closest to the ingress/air inlet of the fan. I designed a DB9 connector into the front panel just in case I want (or need) to update firmware in the future. Apply some gentle pressure so it fixes properly.

The four sides of the tube (only two sides are shown in the diagram) are glued together permanently. 4mm thick plywood (all dimensions in mm): 12x12mm Dowel (all dimensions are in mm): The Internal Fan Surround needs a 115.5mm diameter hole. These fans can be used for this project.

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. The small pieces marked Support Block could be omitted, but are used for strength. I am super impressed. Start by tracing the outline of the fan. For maximum effectiveness, place the extractor close to where you're soldering. Fortunately, the tolerances on the laser cut and 3D printed parts are very tight. I printed the housing in white and filter housing in red to make it a bit more aesthetically pleasing.

This was because I has not initially considered that the fan power would need to be ramped up. Anyway, the PC fan approach does have a few advantages, such as they may already be lying around in an electronics lab, and they are low voltage (12V) so the project is easier from an electrical safety perspective. The square is used to ensure the frame has perfect 90 degree angles. The smoke that arises from soldering is not from the solder metal itself, but from the flux. Want to support Howchoo? Cost could be saved by using a non-anti-static hose. To get around this problem, many fans are stacked up so that air can be sucked through without significantly reducing the airflow rate. I see what the problem is. This is why fume extraction is necessary when you solder on a regular basis; inhaling any kind of smoke can only be a detriment to your health! If you don't have a 3D printer, not to worry! With my new and improving skills in the realm of embedded design, I opted to take my fan controller to the next level. In this tutorial, I will share what I used for so many years. One of those components is flux. By using a fume extractor, you and those around you will be safe from fumes that could be dangerous. All Rights Reserved. I wanted to design a leg that could be easy to use and also the height could be easily changed. Anyway, for occasional home use, I think it could be worthwhile assembling such a device for maintaining your health while working. This only applies if the same HEPA filter and fans are being used otherwise the values will need to be adjusted. For those who love hobby electronics, burning themselves on soldering irons, and figuring out how the world works.

Check out the link below if you want to make your own PCBs for your project. With a knife or small jigsaw, the centre can be cut out. Thank you so much, great work. 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 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. When we solder, we are around lead. 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!). 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. To simplify building the controller, LCD screen is implemented. You whip open your favorite CAD program and get to work on a new design! Can we hope have it released someday soon ? The one I used (known as a Festool 27mm hose, on ebay it can be searched as, The filtering capability is in three parts; filter A is closest to the hose and is a basic, The enclosure is designed for an exact fit around the. We use cookies on our websites for a number of purposes, including analytics and performance, functionality and advertising.

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).

I also added some heat shrink tube for protection. Flux generates the visible fumes seen during soldering. This project cost around 5$ but works like a charm. The enclosure is based on 4mm thick poplar plywood. Then factor in all the sweat equity for designing, physically assembling the prototype, and developing firmware. 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. The ones I ordered came with five filters, meaning you get a total of 20 filters after cutting. Here, you can see that routing is done on both sides of the board, which means it is a dual-layer PCB.

As an experiment I decided to see if it was possible to build one. Next, drill small (3mm approx.) 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. 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. I designed the whole model in Autodesk Fusion 360.

The filters should take out the toxins, but is the smell reduced as well? Exposure to this rosin can cause eye, throat and lung irritation, nose bleeds and headaches. Finally, use the four included fan screws to secure the fan and its grill to the housing. This is the code that will be uploaded to our Arduino when we complete the process. You can probably save a few bucks by soldering your own fan circuit, but the one I'm using is quite powerful and is only about $11. This project will mark my first venture into PIC territory! The panels are laser cut 5mm thick acrylic.

Assembly of the enclosure was a bit tricky.

I am sorry about that, I had intended to do a part 2, but got diverted : ), Building a Low Cost Solder Fume Extractor - Part 2, 1. I wrote a short guide on how to get your 3D model printed without owning a printer. You may notice that your room still reeks of solder smoke, no matter how aggressively the fan sucks up solder fumes off of the work at hand. Test that the HEPA filter (Filter B) comfortably but snugly fits into the assembly, and hits the Filter Stop A/B pieces. Remove the rubber feet and grilles that came with the fan.

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. Assemble the Ingress Plug pieces in the same way. 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).

Breathing in lead is bad.

I don't have any good quality photos but here is a low-quality one. While the result does not compare with high-end commercial extractors, it is better than nothing, and I feel it is slightly better than the low-cost desktop fume extractors which only remove some gasses and do nothing about the smoke particles. Epoxy resin glue will be used to secure the hose adaptor to the Ingress Plate (but first paint the wood; see Part 2). The Aux connector is a mini DIN socket; it will be used for extending the functionality at a later date!
