A square is mandatory for this project, because some accuracy is needed for the cut pieces. And subscribe to my YouTube channel.

Like the internal Ingress Surround piece, the two outer end plates need circular holes cut. Using MPLAB X IDE 5.40 and Microchips free XC8 compiler, I spent many hours with the Rev 1 board to get various bits working; multiplexing the common anode display, rotary encoder software debouncing, learning about PIC ISRs, using the compare-capture (CCP) modules to generate PWM and use hardware timers this project presented a healthy number of challenges for a first go at 8 bit PICs. 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. We're hiring!

and fill out the instant order form with the board's basic information. This only applies if the same HEPA filter and fans are being used otherwise the values will need to be adjusted. 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. Next, drill small (3mm approx.)

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.

But fume extractors are really expensive, like 70$, which beginners like to skip because of the price. Change). As the old adage goes, you get what you pay for. Using a pair of scissors or a box cutter, cut each one down the middle twice, resulting in four 65mm squares of equal size. In the following line, we are going to turn on and off the MOSFETs that are connected to the Arduino Pins 9 and 10.

It's an incredible software to do designing, 123D and SketchUp were good, but Fusion 360 changed the way of designing. I wrote a short guide on how to get your 3D model printed without owning a printer.

That being said, the time and effort spent on this project should pay dividends for all the soldering I have planned across various future projects! The wood enclosure was easy to cut and assemble because it was made from very rigid but thin plywood. An Avnet Company 2022 Premier Farnell Limited.

I came up with this design as final.

To put it simply, it is easy!

Change the information about your board on the PCB specification screen. Commercial solder fume extractors can cost upwards of $70.

:). Furthermore, since it is a custom project, it can be extended for additional functionality. We've put together a guide to help you find the best soldering iron for your next project.

4mm thick plywood (all dimensions in mm): 12x12mm Dowel (all dimensions are in mm): The Internal Fan Surround needs a 115.5mm diameter hole. It basically consists of a hose, some filters and some fanssome fans stacked up behind the filters. With hindsight, I might make it a bit bigger, or else rearrange the assembly method so that a side panel is glued or screwed on last.

At this point the Fan Internal Surround can be glued on two edges and fitted into the assembly. I designed the whole model in Autodesk Fusion 360.

There are a lot of wood pieces, so it helps to label them as soon as they are cut to prevent confusion. The Earth connection is made with a 4mm banana socket.

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).

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. You should be able to upload your Gerber file and send it for review on the next screen. is a company that makes printed circuit boards (PCBs). I also added some heat shrink tube for protection. To simplify building the controller, LCD screen is implemented. 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. Anyway, for occasional home use, I think it could be worthwhile assembling such a device for maintaining your health while working. Building a Low Cost Solder Fume Extractor Part 1, Im sure Ive created some really stinky projects, but this isnt one of them. 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). How much of the smoke escapes through the back? I cut the cabinet with a dremel and then spray painted it. Explore Howchoo's most popular interests. The ingress side is on the left side of the diagram. Today, I'll show you how to build your own for about $20. I shortened it. If you instead used a USB fan (as I did), you'll want to plug this hole so you don't get any air leakage. As an experiment I decided to see if it was possible to build one. If you don't have any small screws laying around, you can also use super glue or epoxy to hold everything together.

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!).

A few lengths of square section wood (preferably hardwood) dowel is also needed; I used 12x12mm section.

If you like this project do vote for it in the contest!

One of the Side A pieces can have all the holes for the connectors, LED and power switch. Apply some gentle pressure so it fixes properly.

I seriously think you are on to something. The repetitions will depend on the thickness of the sponge. fume extractor diy instructables list It can be used as-is, or shortened. To do this, simply use a bit of electrical tape or hot glue. While the laser cut panels and 3D printed bits were on order, I began with fabbing up the first revision of the controller. The enclosure is based on 4mm thick poplar plywood. 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. Firstly prepare the filter. element14 is the first online community specifically for engineers. I came up with this design as final. 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 !! The entire project is more an exercise in woodwork than in much electronics to be honest. 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. Pretty good response time to iosc 's request. Most filters come in a large size, so you need to cut it into the desired size. The result was better than expected with about 5 minutes of sanding.

Now the Ingress End Plate and Egress End Plate can be screwed to the main assembly! These were designed to accommodate the Hakko C1571 duct kit and an off the shelf HEPA filter: Sears Kenmore EF-1, Part #86889. (LogOut/ I also used some washer, but it is not a necessity. 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. 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. The Best Soldering Irons: Read This Before You Invest (2022). There are two potentiometers here that are connected to the 5V and will act as voltage dividers.

I don't have any good quality photos but here is a low-quality one. Check out the link below if you want to make your own PCBs for your project. 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. For this project, we'll be using an amazing 3D-printable model designed by rdmmkr on Thingiverse (thanks, rdmmkr!) If youre interested, click on the Bookmark link for a reminder for Part 2, which will follow shortly!

Static pressure is also decent at 2.63 inches of water, meaning that it should be able to pull air through a respectable filter. 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. Connect the fan to a USB power supply (this is the one I used). Every electronics DIY-er needs a good soldering iron. You can grab the design files if you would like to have a go at building the Rev 2 board as seen here, or designing your own 16F1788 based PCB for any fan control needs. The ones I ordered came with five filters, meaning you get a total of 20 filters after cutting. It is an easy-to-make project because it uses very thin wood that is easy to cut!

Check out our guide on the best soldering irons for different tasks. My activated sponge was large enough so I needed to cut into the required part.

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.

Fortunately, the tolerances on the laser cut and 3D printed parts are very tight. 3. When you have all the parts and the PCB, you can solder them together.

Soft foam material could help, or just glue them together. 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. By using standard sized fans intended for electronics/PC use, cost can be saved if you already have some handy. So, when soldering, it is very important to have enough light and a fume extractor to get rid of the smoke. My design began around a fan and power supply combination I already had in my parts bin. how to get your 3D model printed without owning a printer, The removable filter cartridge front half. Then factor in all the sweat equity for designing, physically assembling the prototype, and developing firmware. There are a few attempts at such a product on the commercial market, but they still required too many compromises to use. Filter C is closest to the ingress/air inlet of the fan. I see what the problem is.

It is available as 3-ply. The DC socket is a usual 2.1mm barrel connector socket for power.

All of the fasteners and corner brackets are off the shelf items from McMaster Carr. :). 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. One of the Side A pieces can have all the holes for the connectors, LED and power switch.

This will also hold the back part of the housing shut. Therefore, breathing in solder fumes is very, very bad. Download the model from Thingiverse and print the five main parts of the model: No supports are necessary. PCBWay is where I got PCB. The idea is that the filters are removable simply by unscrewing the Ingress Plate. A really elegant solution was found by luck; there is a, Open Source Hardware requires membership for participation - click to join. They included solder, and it had the best smelling flux. To do this, find the centre of the the wood and then draw a circle of 115.5mm diameter using a compass. The Howchoo team uses soldering irons all the time for projects like Gamepad Zero or our hacked Raspberry Pi keyboard. Very nice! However, I have only recently (almost two decades later), learned how to solder properly.

The diagram here shows the measurements I used. One of those components is flux. Change), You are commenting using your Facebook account. It will look ugly, but it is very quickly sanded to a neater finish. 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.

Part 2 will cover the rest of this project. Take the grill and glue the DC jack and the switch on it.

This project sucks! You can turn them on by turning on pin 9 and pin 10 of Arduino. The entire unit is powered from an external 12V mains to DC converter. 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. The project is designed around the idea that a lot of electronics that is thrown out contains fans; examples include desktop PCs and servers. First assemble the four Egress Plug A/B pieces into a frame and gluing it, one joint at a time.

Here, I'd like to point out that pins 9 and 10 are PWM pins, which means we can send PWM signals to the MOSFETs. If you need a good soldering iron, then we've got you covered. Assembly of the enclosure was a bit tricky. Google Drive fan controller rev 2 gerbers, BOM, schematic, firmware. To get around this problem, many fans are stacked up so that air can be sucked through without significantly reducing the airflow rate. We use cookies on our websites for a number of purposes, including analytics and performance, functionality and advertising.

A pipe or an outlet, to which this fan can be attached, can be used to ensure that the vapors do not remain contained within the room. 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. Press J to jump to the feed. No adhesives or acrylic cement is used to adjoin the panels; the box is held together with fasteners alone.

Perhaps a speaker enclosure could be repurposed for the outer shell to save some effort. The smoke that arises from soldering is not from the solder metal itself, but from the flux. For those who love hobby electronics, burning themselves on soldering irons, and figuring out how the world works. The downside is also obvious; its a huge box that takes up lots of floor space. Think of it like a 2D printer, but with an extra dimension.

Want to support Howchoo? This is how the PCB looks after the soldering is done. The dowel assembly will be glued onto the end piece, and will be screwed to the main assembly from the sides. There's an internal hole in the unit that's meant to run the fan cord through if you created your own fan circuit. The Jig Piece results in the Filter Stop A/B pieces being exactly 39mm off the ingress side edge of the Side A/B pieces. I think they put something addictive into the flux so you'd buy more kits.

All Rights Reserved.

Since flux is essential in achieving strong solder joints, there is no way around producing smoke when soldering. The fume extractor works to a distance of 20 cm. It is compact enough that very little desk space is taken up; the box could be screwed to the underside of a desk and just the hose needs to be exposed. Poor little guy :'(. I chose to position them centered, 80mm apart. Also, soldering parts onto the circuit board is hard on your eyes, and doing it in low light can eventually damage your eyesight permanently. 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. Fill in your details below or click an icon to log in: You are commenting using your WordPress.com account.

From there, you'll be taken to a form where you can give more information about your board. Saves electricity and makes your home a smarter one with the security of Avnet. I designed a DB9 connector into the front panel just in case I want (or need) to update firmware in the future. Howchoo is reader-supported.

Ideally, I wanted a fume extractor with the following qualities: So what do you do when nothing on the market meets your demands?

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.

To save time, I'm using a 5V fan with a switch and wire built in. The design was created such that the filters and the fans are removable for servicing by unscrewing the respective end plates of the tube. By the way, speaking of this, I got this grill out of an old PC cabinet. PVA (wood) glue was used. Here are two MOSFETs that are set up to work as switches. Test that the four fans (taped together) comfortably but snugly fit into the assembly up to the Fan Internal Surround (see photo below).

To do this, we are going to output PWM signals with values that were generated from the lines that came before them. It will involve painting the wood enclosure, and adding in the wiring, final assembly and then testing it out! Why cant we have a machine that actually filters smoke, but isnt a huge metal box that rolls around on the floor? Take out the power supply and turn on the fume extractor. Filters A and B are quite dense whereas Filter C is like a very aerated sponge and you can see through it. Soldering is awesome, right? When we solder, we are around lead. 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. 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. The diagram here shows the internal layout. 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). 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 . Premier Farnell Ltd, registered in England and Wales (no 00876412), registered office: Farnell House, Forge Lane, Leeds LS12 2NE. Pretty good response time to iosc 's request. 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. The panels are laser cut 5mm thick acrylic. 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.
