well that might leave a grainy casting, as long as the sand held the shape it might be interesting. But thanks for the reply.
Could one use this as a mold? In place of green sand?
the thing is that all that should be done within the interrupt is the counter is increased period. Nothing else. If you need a delay do it outside of the interrupt.
Your interrupt does not look very efficient, I thought one wants to be in and out of an interrupt as fast as possible, you even have a delay in it. Of course as you are only doing one thing it probable does not matter. I would be doing more things.
Wow, thanks that explains it!!
Nice article, thank you!!re:Step 6: Countersink the HolesWhy would you bother countersinking the holes?The hole is covered by the insert, the screw head sinks/sets in the insertnot the tool.
Great, thank you for posting. Very nice dies I would like some instruction on machining them.
WOW, sets all sorts of ideas afloat in my head! Thanks
The Sketchup download does not work!!The download is a random name.tmp file that is not a .sch
could you send me a nag for taking the class, it is all so interesting and someday I will need it but not now, so it is not high on my to-do list but maybe with some nagging....
Thanks for the replies, that is very interesting. I will stick with X Left/Right Y Front/Back and Z Up/Down
Great article thanks. None of my 3D experience ever had Y as the up-axis. X front back Y left right Z up down. If you do not believe Y should be up down why promulgate the idea? Or is that Fusion references the axis?
"I can see that the surface to be cut is actually taller than the material to be cut, so not I need to scale the surface down in the Y dimension"Shouldn't that be Z dimension?
First thing THANKS EVERYONE FOR YOUR CONTRIBUTIONS!!I finally got it working thanks to your help!!markwills, it was your code that finally worked.Now what /why are the pins defined?#define En_pin 2#define Rw_pin 1#define Rs_pin 0#define D4_pin 4#define D5_pin 5#define D6_pin 6#define D7_pin 7#define BACKLIGHT 3How would they be used?Thanks again,Ralph
Hope someone is still monitoring this thread.I ran the blink code and the LED blinks rapidly BUT then it stops!!The On led is now on and the SCK led is slowly blinking but the led on Pin 14 no longer blinks!!
actually some recommend not drilling in straight lines, it helps to hold yourcomponents while they are being soldered if some of the holes are offset!
Technically any "paper" that light will diffuse through, actually any material could be used like toilet paper etc.
Thank you, the lathe work is just what I need as I am just starting out machining, and then the heat treating loved it short and informative!!
now how to put a potentiometer to control speed?Thanks for instructable
djalmao23, says it works with a 5A/12V CC motor.I would like to know the max amperage, also what modifications are needed to handle a heavier load?
