The schematic was drawn in Sunstones free printed circuit board design program, PCB123. PCB123 does not allow any format other than theirs. The only way to transmit the schematic to design news was via a screen capture and a JPG conversion. If you want an electronic version, I will be happy to email anyone a copy. But PCB123 does not allow any format other than theirs, so you will have to download PCB123 to be able to open it. If you are interested, email me and I will send you a schematic and the code for the PIC. If you plan to build one, I would be happy to program the PIC for you if you don't have the means to do so.
The force is simply the hydraulic pressure times the surface area of the cross section of the ram. The pressure transducer was calibrated in the laboratory and the instrumentation amp gain is set to allow maximum range for the A/D converter in the PIC. The PIC does the simple E.U. conversion to provide the LCD display with actual pounds force exerted by the ram.
I agree. Seems like a very practical idea. I'm curious, though. In hydraulic ram press applications in the past, how was the force calculated? Mr. Nauman mentions counting the number of pumps on a handle. Was the calulation really that crude?
Now, that's a really practical device a lot of shops can actually use. I'd love to see the source code but I can understand it not being there. You could actually market the device. What transducer did you use? I like the fact that you made it look good by putting the lettering on the front panel. It shows you didn't just make it for yourself. Good work.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
The IEEE Computer Society has named the top 10 trends for 2014. You can expect the convergence of cloud computing and mobile devices, advances in health care data and devices, as well as privacy issues in social media to make the headlines. And 3D printing came out of nowhere to make a big splash.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
