Explore Howchoo's most popular interests. Exposure to this rosin can cause eye, throat and lung irritation, nose bleeds and headaches. In the following line, we are going to turn on and off the MOSFETs that are connected to the Arduino Pins 9 and 10. You should be able to upload your Gerber file and send it for review on the next screen. 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 !! This project sucks! The fume extractor works to a distance of 20 cm. The relay gives the operator full control over any fan without having to turn the main DC supply on/off. Premier Farnell Ltd, registered in England and Wales (no 00876412), registered office: Farnell House, Forge Lane, Leeds LS12 2NE. (EDIT: Here is Part 2: Building a Low Cost Solder Fume Extractor - Part 2 ), I built quite a few Heathkit products back in the day. All of the fasteners and corner brackets are off the shelf items from McMaster Carr. These fans can be used for this project. My design began around a fan and power supply combination I already had in my parts bin. The reason is, since the HEPA filter is very dense, if air-tightness is not achieved for the fans to the filter side, then the air flow will take the easier path, short-circuiting around the fans : ) Similarly, each fan frame needs to be air-tight against the next. So, the Arduino Nano is basically the brain of this project, but you can use any Arduino board. 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. Improved version of the soldering iron controller for Hakko 907 iron. The filter will be held in place firmly when the end plate, the Ingress Plate, is screwed 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. 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. Change the information about your board on the PCB specification screen. And here you can see an LM 741 comparator IC, which can be used to power any other devices you want. Cool!! Saves electricity and makes your home a smarter one with the security of Avnet. Rosin is a serious occupational health hazard. The filters should take out the toxins, but is the smell reduced as well? The diagram here shows the internal layout. Though I could connect batteries if needed. By using standard sized fans intended for electronics/PC use, cost can be saved if you already have some handy. Note: This is part 1 of a two-part project. Pretty good response time to iosc 's request. After the firmware on Rev 2 had reached a satisfactory state, I opted to finish the internal wiring and button up the entire assembly. Take out the power supply and turn on the fume extractor. It's an incredible software to do designing, 123D and SketchUp were good, but Fusion 360 changed the way of designing. Check out our guide on the best soldering irons for different tasks. If you don't have any small screws laying around, you can also use super glue or epoxy to hold everything together. The pieces of wood that are required and all dimensions are listed below. When assembling it, one important step is to ensure that the Fan Ingress Surround is air-tight when glued to the sides. Remove the filter and fans, and glue on the final remaining side piece (Side B). Only the filter box and plenum are 3D printed parts. I printed the housing in white and filter housing in red to make it a bit more aesthetically pleasing. Every electronics DIY-er needs a good soldering iron. 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. All Rights Reserved. Fan suction will hold the tape in place tightly. While the laser cut panels and 3D printed bits were on order, I began with fabbing up the first revision of the controller. The project is designed around the idea that a lot of electronics that is thrown out contains fans; examples include desktop PCs and servers. 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. Thank you so much, great work. An Avnet Company 2022 Premier Farnell Limited. I came up with this design as final. To do this, simply use a bit of electrical tape or hot glue. With hindsight it could also be possible to use a bathroom fan or other fan intended for connecting to ducting within a building. It didnt occur to me at the time. 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. Are you a passionate writer? 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 Ingress Plate needs to connect to the hose. Start by tracing the outline of the fan. With a sharp pencil you can mark (for cutting and sanding operations) to sub-millimetre accuracy, and then during assembly, by looking at the gap between the square and the workpiece, it is possible to get an extremely precise 90 degree alignment. Firstly prepare the filter. The pins are given in the diagram. 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. Most filters come in a large size, so you need to cut it into the desired size. Of course, the information and files provided are for recreational (non-commercial) use only; no guarantees are expressed or implied. 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. 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. PCBWay is where I got PCB. The input voltage is connected to a 7805 voltage regulator, which will turn the VIN into a steady 5V DC supply. Since there is lots of symmetry many of the pieces are needed in quantities of 2. Here are two MOSFETs that are set up to work as switches. A site dedicated to projects I do for fun. If you don't have a 3D printer, read on and I'll share some ways you can get your model printed. Download the model from Thingiverse and print the five main parts of the model: No supports are necessary. From there, you'll be taken to a form where you can give more information about your board. To get around this problem, many fans are stacked up so that air can be sucked through without significantly reducing the airflow rate. Solder contains lead. Soft foam material could help, or just glue them together. 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. The entire project is more an exercise in woodwork than in much electronics to be honest. element14 is the first online community specifically for engineers. 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. As an Amazon Associate, we may earn a small affiliate commission at no cost to you when you buy through our links. The result was better than expected with about 5 minutes of sanding. 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. 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. Soldering is an essential practice in any makers repertoire. The idea is that the filters are removable simply by unscrewing the Ingress Plate. Change), You are commenting using your Twitter account. Why cant we have a machine that actually filters smoke, but isnt a huge metal box that rolls around on the floor? Part 2 will cover the rest of this project. :). The small pieces marked Support Block could be omitted, but are used for strength. Ive wanted a solder fume extractor for home use for ages they are quite pricey though. 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. The ingress side is on the left side of the diagram. APC 2200XL UPS electrical refurbish + old vs new componentcomparison, Military Jet Engine Generator Repair MEP362A, Bench-top (footprint < 1 square foot, shallow depth facing the operator), Multi-stage filtration using easy to find, off the shelf filters. The Egress Frame A/B pieces are used to provide some thickness for attaching the Egress End Plate (not shown on the diagram). Use two small screws to secure it in place. It has the properties that it is rigid but slightly springy, very flat and stable, and cuts easily, and can be very quickly sanded to size with a sanding block and 150-200 grit paper. 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. Press question mark to learn the rest of the keyboard shortcuts. The enclosure is designed for an exact fit around the HEPA filter because that is the largest component. This is the code that will be uploaded to our Arduino when we complete the process. After all the four nuts are fixed, take the sponge that we had cut in Step 1 and push it between the bolts and press so there are no gaps left. I designed the whole model in Autodesk Fusion 360. Solder the red wire to the +V and black wire to the Ground. 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!). Remove the rubber feet and grilles that came with the fan. The Aux connector is a mini DIN socket; it will be used for extending the functionality at a later date! 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. Since the fans are smaller than the tube, they are centred inside the tube using the Fan Support A/B pieces. Since flux is essential in achieving strong solder joints, there is no way around producing smoke when soldering. The photo here shows the fans being tested for fit; they are taped up together and they they should easily slide in from the egress side. This is also possible because the filters are housed in a separate compartment. 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. Being that this my first time using PIC, I knew the learning curve was going to steep! 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. Combine that with the cost of good soldering irons, and you're looking at some expense. By the way, speaking of this, I got this grill out of an old PC cabinet. 2. is a company that makes printed circuit boards (PCBs). Soldering is awesome, right? 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. I made a similar build, but used one of these, and a DC adapter instead of batteries. I seriously think you are on to something. I didnt see any smoke coming from the back, but it couldve been dispersed by the fan to make it harder to see. Then factor in all the sweat equity for designing, physically assembling the prototype, and developing firmware. Check out the link below if you want to make your own PCBs for your project. There are two potentiometers here that are connected to the 5V and will act as voltage dividers. holes just inside the circle. 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. This is pretty much the whole circuit. In particular the ones that filter the fumes. 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. The Ingress Plate needs to connect to the hose. Can we hope have it released someday soon ? It can be used as-is, or shortened. Perhaps a speaker enclosure could be repurposed for the outer shell to save some effort. Whats the best practice for soldering these types of Can anyone visually see anything wrong with this GPU PCB? The hose is an anti-static one, to prevent static electricity build-up from particles in the air. Think of it like a 2D printer, but with an extra dimension. 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. How to make a DIY Rocket Launcher using Arduino - Design the circuit, make a rocket ignitor and control the launcher from your phone. The fan array will drop in from the right side of the tube, until it hits the Fan Ingress Surround. Leg stuck in hole in pcb, cant melt out using everything Amazon Fire Stick 4K - redirect Micro USB help. Building a Low Cost Solder Fume Extractor Part 1, Im sure Ive created some really stinky projects, but this isnt one of them. As the old adage goes, you get what you pay for. A really elegant solution was found by luck; there is a, Open Source Hardware requires membership for participation - click to join. The DC socket is a usual 2.1mm barrel connector socket for power. We are taking the analog readings from the two pots, and within the loop function, we are mapping those readings to a value that falls somewhere in the range of 0 to 255. Hopefully you get a kick out of it! 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! The soldering iron controller based on arduino that implements PID method to keep the temperature of the 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 entire unit is powered from an external 12V mains to DC converter. 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. 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. Anyway, for occasional home use, I think it could be worthwhile assembling such a device for maintaining your health while working. The dowel assembly will be glued onto the end piece, and will be screwed to the main assembly from the sides. 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. I have the files uploaded here on Thingiverse so you can also use it. 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. Very nice! I also added some heat shrink tube for protection. Assemble the Ingress Plug pieces in the same way. In the setup function, we are going to declare the pin mode, which is essentially going to tell the Arduino whether the pins are input pins or output pins. Cost could be saved by using a non-anti-static hose. Commercial solder fume extractors can cost upwards of $70. To put it simply, it is easy! It's an incredible software to do designing, 123D and SketchUp were good, but Fusion 360 changed the way of designing. :). 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. It was an extremely tight squeeze, but everything did fit in. Assembly of the enclosure was a bit tricky. The design was created such that the filters and the fans are removable for servicing by unscrewing the respective end plates of the tube. There are a lot of wood pieces, so it helps to label them as soon as they are cut to prevent confusion. The Fan Support A/B pieces can now be glued into place, using the Support Blocks as needed. 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. You can then turn the fan on and off using the controls on the fan's USB cable. Poor little guy :'(. Filters A and B are quite dense whereas Filter C is like a very aerated sponge and you can see through it. The Howchoo team uses soldering irons all the time for projects like Gamepad Zero or our hacked Raspberry Pi keyboard. 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. So, is it possible to combine the best of both worlds? A square is mandatory for this project, because some accuracy is needed for the cut pieces. 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). The enclosure is based on 4mm thick poplar plywood. shabaz clearly has blog writing super powers! However, I have only recently (almost two decades later), learned how to solder properly. When you buy a tool or material through one of our Amazon links, we earn a small commission as an Amazon Associate. The first time I soldered was also around the first time I could hold a pencil. Static pressure is also decent at 2.63 inches of water, meaning that it should be able to pull air through a respectable filter. One of the Side A pieces can have all the holes for the connectors, LED and power switch. One of the Side A pieces can have all the holes for the connectors, LED and power switch. I used four fans. My activated sponge was large enough so I needed to cut into the required part. Test that the four fans (taped together) comfortably but snugly fit into the assembly up to the Fan Internal Surround (see photo below). 3. This project cost around 5$ but works like a charm. I made the holes centred 26mm off the egress side edge. I don't have any good quality photos but here is a low-quality one. 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. Therefore, breathing in solder fumes is very, very bad. Next, a Side A piece can be glued into position (dont glue to the Ingress Plug, as mentioned use that just as a support for now). Pretty good response time to iosc 's request. This is exactly the size you'll need. 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. and fill out the instant order form with the board's basic information. Furthermore, since it is a custom project, it can be extended for additional functionality. I also used some washer, but it is not a necessity. I see what the problem is. 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. PCBWay is a company that makes printed circuit boards (PCBs). Filter C is closest to the ingress/air inlet of the fan. I think they put something addictive into the flux so you'd buy more kits. With my new and improving skills in the realm of embedded design, I opted to take my fan controller to the next level. 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 . The repetitions will depend on the thickness of the sponge. 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. A place for solderers from around the world, to gather, help one another, and hang out. You whip open your favorite CAD program and get to work on a new design! The design intent is focused on keeping the box as compact as possible. There's an internal hole in the unit that's meant to run the fan cord through if you created your own fan circuit. There is not a lot of wasted space between the fan and the power supply. (LogOut/ Once the prints are ready, it's time to assemble everything. I wanted to design a leg that could be easy to use and also the height could be easily changed. How much of the smoke escapes through the back? Make sure the Fan Ingress Surround is also air-tight against the fans! Better to glue them. 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. Let's get started coding right away. Next, drill small (3mm approx.) The dimensions in the project leave very little space for the electronic connectors/components. 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).
