How to Make PCB at Home

Metal has been worked by humans for thousands of years. Over time, the techniques and technology used to produce and shape metal goods have been driven by the innovations of science and technology. Before we dive into some of the technical processes available for welding metal together, let's first take a moment to define a weld. A weld is a fabrication process that joins materials, usually metals or thermoplastics, by fusion. Fusing materials is distinctly different than other kinds of lower temperature metal-joining techniques such as soldering, which do not melt the base metal.

Metal welding is the fusing of two pieces of metal to create one solid continuous piece. All welders work on the same principle: A gas torch or electric welder is used to generate precisely directed heat to melt material, and a filler material is introduced by the operator to complete the fusion.

With time has come innovation and accessibility, and now we've come so far that you - yes YOU! Let's get started! Choices in Beginner's MIG w elders. This class is designed for those who are completely new to welding. Throughout this course, amateur metalworkers will learn ideas and tips about how to become skilled welders, ready to push their making craft to the next level.

I learned how to weld in college when I took a drop-in advanced sculpture class while constructing my thesis project. I learned primarily Oxy-Acetelene welding to do very fine wire work. To this day, I think Oxy welding is my favorite technique, but it's not practical for every application, and not as fast as MIG. I learned MIG welding when learning how to repair bicycles in Reno, and my neighbor handed me the gun to their flux-cored v welder and said, 'Ok, now you do it'.

I explained I had never used a MIG welder before and they turned to me and said: "It's just like using a really hot glue gun. I've taken on large welding projects for Instructables builds, and have done structural welding on sculptures that have traveled around the world. In short, I'm no pro or expert, but I'm self-taught, experienced and can provide a great pathway to get you metalworking and welding in no time. MIG welding can be safe as long as you follow a few important safety precautions.

Welding metal requires us to protect ourselves from the many dangerous aspects of the trade with safety gear to prevent us from getting burned or blinded. An auto-darkening welding helmet protects our eyes from the light that is generated by any form of arc welding but allows you to see when the arc of the torch is not active. Auto-darkening helmets are helpful if you are doing a bunch of welding and don't want to jerk the helmet off and on to see what you are doing in between welds.

If you work in a community shop with lots of people, protecting others from seeing the arc by using a welding screen. The screen protects potential on-lookers from getting blinded by the arc. Having your skin covered is critical. Once you start grinding and welding, hot sparks and molten metal slag can shoot in all different directions. We protect ourselves by wearing heat-resistant leather and natural fiber; synthetic fabrics melt instead of burn, meaning they become molten and burn into the skin, yikes!

But honestly, a leather jacket is really hot to wear for any extended welding project. If you're like me and heat up quickly, you can try a welding apron with a long sleeve flame-resistant cotton shirt. Most of the time, I wear coveralls that have been rated for use with welding. They cover all my skin, and I can tuck the sleeves into my gloves when I'm welding, or easily roll them up when I'm grinding.

This cover will not only protect your skin from the heat produced by welding, it shields your skin from the UV light produced by welder's arc. Just like your welding clothes, you are going to want wear very sturdy work shoes that do not have any synthetic materials that could melt. Good work boots or even canvas slip-ons are fine - just no running shoes. If I'm going to be welding for more than 15 minutes, I'll even put on sunscreen.

I've occasionally gotten sunburns on my neck from the small gap between my leathers and my helmet, but SPF seems to do the trick. When you are welding, you will be gripping and traverse your hands and forearms along some very hot metal.

For this reason, we wear MIG welding gloves. Be warned,MIG gloves are the most uncomfortable gloves in the world. They should fit loose so that if they become too hot, you are able to quickly fling them from your arm on to the ground. Wearing a grinding visor protects your face from flying particulate while you are using a grinder. If you are working to grind off paint, or any other kind of metal finish, consider wearing a face mask to protect you from potential fumes on the steel coating.

I wear safety glasses under my welding helmet for the sole reason that I make sure I am wearing them once I start grinding metal. The safety glasses I recommend have a Z This rating ensures that your eyes are receiving some UV protection from other welders around you, and from flying sparks when you're grinding.

You also want to protect your ears while welding and grinding by wearing ear muffs or ear plugs. When the fast-spinning grinding wheels come into contact with the steel it is super duper loud, and prolonged exposure can cause pain or even temporary deafness. It's important to weld in a well-ventilated area.

MIG welding produces fumes which you shouldn't breathe in. If you are going to be welding and working for longer than 30 minutes, wear either a mask or a respirator that can protect you from metal fumes.

Galvanized steel contains a zinc coating that is applied to industrial steel to prevent rust over a prolonged period of time. Think streetlamps, and bridge supports This zinc coating produces carcinogenic and poisonous gas when it is burned. Exposure to the immolated coating can result in heavy metal poisoning also known as 'welding shivers'. These are flu-like symptoms that can persist for a few days, but that can also cause permanent damage.

This is not a joke. I have witnessed someone who has welded galvanized steel out of ignorance and immediately felt the effects and had to be rushed to the hospital, so don't do it! Molten metal slag can splatter several feet from a weld.

Grinding sparks can fly even further. Any sawdust, paper or plastic bags in the area can smolder and catch fire, so keep a tidy area for welding. Most often, your attention will be focused on the parts you are welding, and not the area around you, so it can be hard to see what's going on behind you if something catches fire. Reduce the chance of that happening by clearing away all flammable objects from your weld area.

This is a good precaution for any shop, but keep a fire extinguisher beside the exit door from your workshop. CO 2 extinguishers are the best type of extinguisher for welding.

Water extinguishers are not a good idea in a welding shop since you are standing next to a machine which essentially transforms wall power into lightning. The main types of welding used in industry and by home engineers are commonly referred to as MIG welding, TIG welding, arc welding, gas welding. Hands down, MIG welding is the most common form of welding practiced, but there are other options for fusing metal together. The GMAW process is suitable for fusing mild steel, stainless steel as well as aluminum.

MIG M etal I nert G as welding is a semi-automatic arc welding process in which a consumable wire electrode and a shielding gas are fed through a welding gun, also known as the torch.

The machine produces massive electrical current that travels through the consumable wire to your work pieces fusing and melting both the wire and the base metal together.

MIG welding was developed in the 's as a way to speed up the way production welders fuse materials in factories during and after WW2. Seventy years later, the general principle is still very much the same but most MIG welding equipment has been modernized with better parts and some even have onboard computers. MIG welding uses an arc of electricity to create a short circuit between a continuously fed positive anode the wire-fed welding gun and a negative cathode the base metal being welded.

If you want a greater understanding of the core principles of electricity check out the Electronics Class. The heat produced by the short circuit, along with a non-reactive inert gas, melts the metals under the welding torch and allows them to mix together. Once the heat is removed, the metal begins to cool and solidify, forming a new piece of fused metal. MIG welding is useful because you can use it to weld many different types of metals: carbon steel, stainless steel, aluminum, magnesium, copper, nickel, silicon bronze and other alloys.

This class only goes over how to fuse mild steel, but your welder's manual will have advanced instruction on how to weld other materials. Oxy-Acetylene Torch Welding , more commonly Gas Welding and Cutting , are not used as widely for general welding of mild steel, but great for very delicate assembly of small ornate parts. This form of welding is one of the earliest industrial forms of welding.

Gas welding consists of mixing oxygen and acetylene gas to create a flame capable of melting steels. The gas torch is commonly used for brazing softer metals such as copper and bronze, but can also be used for welding delicate aluminum parts such as refrigeration pipes. TIG welds are best suited for out high-touch work, such as sculptures and architectural features. TIG welds provide a superior finish that needs minimal clean up by sanding or grinding. TIG welding provides a very clean way to weld.

In one hand you wield a torch electrode and connect ground to your base material. You activate the flow of current with a foot pedal and control the amount of current on the welder.

Instead of a consumable wire feed being burned from the torch, the person welding gently feeds filler material from a rod into the welding pool. Since you control the feed of material, slag splatter is minimal. If you are interested in learning more about TIG welding, check out this Instructable. Welder making boilers for a ship, Combustion Engineering Co. Photograph by Alfred T. Arc welding works by clamping a current producing electrode onto a coated consumable stick of material.

An electrical arc travels from the tip of the consumable electrode to the base material underneath. The distance between the electrode tip and base material controls the amount of heat being generated by the super hot electrical arc. Arc welding is best suited for structural manufacturing, construction, and large-scale repairs. Arc welds get very very hot, and can burn out thin material easily, thinner materials are more suited to the MIG welding processes.

Before going further in this class, please note that the lessons in this course only go over one of the kinds of welding listed above, MIG welding. MIG welding is the most common form of welding, albeit the price tag associated with a MIG welder can be high, it is the most accessible of welding skills to learn.

See-through circuitry: New and cheap alternative for transparent electronics

High-performance electronic circuits made entirely from transparent materials could have countless applications, from head-up displays on car windscreens to transparent TV sets and smart windows in homes and offices. Researchers at KAUST have found a way to make transparent transistors and other essential components of electronic circuitry using inexpensive and readily available materials and a simple fabrication technique1. Indium tin oxide ITO is the current material of choice for electronics because it combines optical transparency with electrical conductivity. Its use ranges from touch-sensitive smartphone screens to light-harvesting solar panels.

A speedometer is a device used to measure the traveling speed of a vehicle, usually for the purpose of maintaining a sensible pace. Its development and eventual status as a standard feature in automobiles led to the enforcement of legal speed limits, a notion that had been in practice since the inception of horseless carriages but had gone largely ignored by the general public. Today, no automobile is equipped without a speedometer intact; it is fixed to a vehicle's cockpit and usually shares a housing with an odometer, which is a mechanism used to record total distance traveled. Two basic types of automobile speedometer, mechanical and electronic, are currently produced. The concept of recording travel data is almost as old as the concept of vehicles. Early Romans marked the wheels of their chariots and counted the revolutions, estimating distance traveled and average daily speed. In the eleventh century, Chinese inventors came up with a mechanism involving a gear train and a moving arm that would strike a drum after a certain distance. Nautical speed data was recorded in the s by an invention called the chip log, a line knotted at regular intervals and weighted to drag in the water. The number of knots let out in a set amount of time would determine the speed of the craft, hence the nautical term "knots" still applied today. The first patent for a rotating-shaft speed indicator was issued in to inventor Nikola Tesla.

A printed circuit board PCB mechanically supports and electrically connects electronic components using conductive tracks, pads and other features etched from copper sheets laminated onto a non-conductive substrate. A printed circuit board has pre-designed copper tracks on a conducting sheet. The pre-defined tracks reduce the wiring thereby reducing the faults arising due to lose connections. One needs to simply place the components on the PCB and solder them. Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson.

These kits come with all necessary components and PCB to assemble yourself. The physical design of the PCB was very important to the final product—particularly since it snaps apart and parts of the PCB are used as supports. A photo-realistic view of PCB components aids in accurate electromechanical product design. An example is a metal enclosure that the PCB is mounted into.
