We’ve seen several people create custom dies for their brakes, and the results have shown the concept has merit for small-scale production. After 5 years, I just have nothing much to learn.Using 3D printed forms to bend sheet metal isn’t exactly new. As I said, I spent 5 years at this business and learned all their tools inside and out. They literally gave me a 40 raise by simply advocating for myself. I was shocked and dumbfounded. Through these tactics, I went from making 50k to making 85k, overnight.1 hour charge time on DCB118 fast charger. It is perfect for higher demand tools like demo hammers and grinders which need longer runtime. But judging by his recent experiments, is very close to changing that perception.This battery offers no memory and virtually no self-discharge for maximum productivity and less downtime. A bend here or there is one thing, but the ability to form a complex shape with them has always seemed like asking too much.The screws are way TOO SMALL to handle any other way.The process at work here is, relatively speaking, pretty simple. 1) You ABSOLUTELY need a good magnetized 000 Philips screwdriver. 08mm pentalobe screws which hold the case closed are HUGE compared to the screws which await you within.Of course, that’s vastly oversimplifying things. A wireless remote kit that'll make turning on holiday lights (or honestly, any lights) a snap no fumbling with a bunch of light. If everything works correctly, and your CAD skills hold true, the metal will take the desired shape.Get it from Amazon for 76.47+ (available in two colors).
But he’s confident with some more refinements he could get a repeatable process going, and thinks ultimately producing runs of up to 100 parts on a set of printed dies isn’t out of the question.Logically, it would seem plastic isn’t an ideal choice for punching and shaping metal. Even still, he’s had a lot of trouble getting the printed parts to survive multiple uses. The first ones shattered under the pressure, and it took a few design revisions and eventually a switch to a stronger resin before got a set of dies that could form the desired piece. So it’s a good thing you can rapidly redesign and reprint the dies.Which isn’t to say that the dies themselves didn’t come with their own unique set of challenges. The reference is available in a range of voltages, his chosen 2.048 volts gave a 2.048 mA current sink with a 100 ohm resistor.In a way it is a miracle of technology that the cheapest digital multimeter on the market can still have a surprisingly good level of calibration thanks to its on-chip bandgap voltage reference, but it never hurts to have a means to check your instruments. An Analog Devices precision voltage reference driving a low-offset op-amp with a driver transistor supplies current to a 0.01% precision resistor, resulting in a reference current source fit for his needs. 0.02% accuracy would suffice. Had enough need for a calibrated current source to have designed his own, and he’s shared the resulting project for all to see.The cost of a reference source goes up with the degree of accuracy required, and can stretch into the many millions of dollars if you are seeking the standards of a national metrology institute, but fortunately ’s requirements were considerably more modest. You can see such tools in action in our earlier coverage of this approach here and here.’s previous work was printed at 80% infill and 12 walls, and failed at 5 tons. Some types of tooling can be 3D printed, and it turns out that printed tools are not only fast and economical, but can be surprisingly resilient. Printed in PLA, with 80% infill and 12 walls, the tool (right) failed at 5 tons.In a press, material such as sheet metal is formed into a shape by forcing the material around the tooling. Posted in Tool Hacks Tagged calibration, current, voltage, voltage referenceReddit user has been making brake press tooling with 3D printed PLA, and recently shared an interesting picture of a hybrid brake press punch, shown here on the right, in blue. Posted in 3d Printer hacks, Tool Hacks Tagged 3d printed, hybrid, press brake, sheet metal, tooling doesn’t much like breadboarding. Having to re-cut a tool because it isn’t quite right in some way is expensive and costly, and it’s much easier and cheaper to go through that process with 3D printing instead of metal. It’s a clever idea, and an apparently effective one.The goal with these 3D printed tools is twofold: doing short-run work, and reducing costly rework when developing “real” tooling. The new tool made it up to 7 tons before failure. Cs3 torrent for macThe usual way to strip away the enamel and reveal the shiny copper underneath is to scrape it off, but that would get tiresome when working with a lot of connections. This enamel acts as an electrical insulator. The solder will bubble away the enamel and tin the copper underneath in the process.Magnet wire is a thin, solid-core conductor that has a clear coating of enamel. Push the tip of the magnet wire a small distance into the molten solder and hold it there for a few moments. That may sound troublesome to some of you, but has come up with a few tips to make prototyping with perfboard and magnet wire easier and more effective, and the biggest tip is about how to manage stripping all that magnet wire. Battery For A 40 Year Old Small Screw Tool Code To HimselfThe emphasis is on understanding what is actually happening inside the circuit, which explains the title of the talk: Debugging Electronics: You Can’t Handle the Ground Truth! So we can compare observed behavior against designed intent. The newly published talk video embedded below.Beginners venturing just beyond blinking LEDs and premade kits would benefit the most from information here, but there are tidbits useful for more experienced veterans as well. They almost never work on the first try, and thus we step into the world of electronics debugging with Daniel Samarin as our guide at Hackaday Superconference 2019. After checking for obvious problems you apply power and… it didn’t do what you wanted. It looks like he’s keeping the source code to himself for the time being, but hopefully he sees fit to release it in the future a project of this caliber deserves to become more than a one-off creation.Continue reading “A Wireless Controller For The Mostly Printed CNC” → Posted in Tool Hacks Tagged cnc, CNC controller, handheld, MPCNC, remote, touchscreenCongratulations, you have just finished assembling your electronics project.
