forgery

Image
 Ronny and Matt from Church invited some youth to try simple forging.  Ronny brought an anvil and some know-how.  Matt brought a little propane forge. Starting from some simple rod stock, a couple guys each got to pound on the red hot metal: to make a stylish little letter-opener:  I got to hammer too, and made a wee "garlic cleaver": I didn't do much of the metal - i just supplied some dumb hammering while Ronny moved the work - but I was proud of the handle: I cut off 5" of an oak branch that had fallen during the recent storm, shaped it with a rasp, then burned it with a blowtorch to get the color.  I sealed it with a quick clear coat spray.  The handle only took about 90 minutes (mostly the rasp), and I was pleased with the comfort and color. I mounted it on the blade by drilling a hole in the wood (slightly undersized for the tang), heating up the metal to really hot, and shoving them together.  The hot metal burned its sha...

The way it goes

I wanted to install a ceiling fan where there was only a ceiling light.  No problem!  I've done this many times before - maybe 30-45 minutes is plenty. HAHAHAHAHHAHAHAHAHHAA! As so often happens in projects, this one snowballed and wound up taking over 3 hours .  Follow along with these easy-to-repeat steps and see if you can tell where the problem lies: Step 1 - Remove the old light fixture finger screws for the glass bowl -- easy peasy. a screw or two holding the light housing to the junction box --  boy, this box is pretty wiggly. the wirenuts and ground wire connecting the light to the supply --  hot wire is off; all is well. Pro tip: It's a good idea to turn off the breaker, but chances are good your breakers are labeled incomprehensibly or are outright lies.  What I do is turn off the room switch and then quickly tap the hot wire with a finger to see if i get zapped.  I didn't this time! Surprise!  A pleasant surprise!...

mac -> arduino -> pi -> perfboard -> regulators -> servos

This is a continuation of the small electronics / microcontroller project mentioned earlier in http://evandaprojects.blogspot.com/2017/11/robot-claw-prototype.html http://evandaprojects.blogspot.com/2017/11/first-pi-project.html http://evandaprojects.blogspot.com/2017/11/pi-prj-1-update-1.html But I've shifted gears and instead of a gantry-like ASRS, I was thinking of trying to make a robot arm. Structure As usual, I will use a lot of what i have on-hand, and so instead of fancy aluminum t-channel structural members, I'll use 2x4s that I'll rip into thin slabs. I figured it'd need to rotate.  I didn't have any lazy susan bearings, so i stuck some casters on a board.  It could be smoother. Arms will get mounted to it using pieces of melamine (left over from the concrete casting)  and bolts (reclaimed from a bench swing that got crushed by a fallen tree). I made sprockets or gears - we'll see how i use them - with timing belt and plywoo...
