  • Articulating Electric Mechanical Wings

    At this age I was building balsa-wood rafts atop an upturned shoe box. The only thing close to being electromechanical was the flashlight bulb inside the cabin. I very much enjoyed reading your story. Might I suggest a hinge down the centre of the backplate so the wings could be folded together when transporting them.

  • Mini Concrete Blocks - All Weather Building!

    We will of course require an upgrade to our bolly truck to transport these to the park, and back. Absolutely delightful and lovely photographs.

  • Automated Air Canon With Videos

    It is your simple mechanism I'm interested in. Our screen door need you to open it a tad more before it auto closes. I can see now detecting it left open and simply winding up the trigger and then auto releasing it. We'll see how long this idea takes to build, only four more Christmas cards to do!

  • Japanese Inspired Self Filling & Cleaning Bird Bath

    Nice design. We've added a small sunken rock in our bath so that short legged birds can safely 'paddle'.

    Gas Powered Blender of DOOM

    I've toasted two kitchen blenders trying to make a mulcher for the garden compost. My original bowl was a 10" auto funnel from Canadian Tire. The second a 13"dia garbage bin. In both cases the 'bowls' survived but the motors didn't. My most recent attempt used a garburator someone dropped off at the shed, to which I added a 2"dia recycle pipe. This time the motor survived but the flow kept jamming up. Only later did I discover it wasn't a garburator but a dishwasher unit! We must persevere....

    Medusa Newspaper Hat

    The Medusa hat, if rolled up at an angle will make a tree. We once made one with the Manchester Evening News which climbed from the living room floor to the ceiling. When Our parents came home and finally went to bed they found the last yard sticking out of their bedroom floor.

  • Robotic Cam Steered Vehicle

    After WWII there were lots of mechanical 'bomb timers' available in the back streets of Manchester and Uncle Derek put one in the back of a model frigate which controlled the rudder. I'm not sure he knew what the ship was going to do but it was fun watching it cavort about the pond and then dashing off to catch it when it headed off on it's final tack.

  • Design & Build a Truncated Icosidodecahedron!

    For your interest here is a version of a 5ft Bucky Ball cut out on a home brew CNC machine. The paintings were of old Mills in Lanark County, Ontario, and are presently hung on a Wall in the Mississippi Valley Textile Museum. We used LinuxCNC to run the CNC with a fixed row of holes in each side to join it all together. Wikipedia was a great source for providing the 138.80 deg and 142.62 deg for the angled plates etc. Almonte and Area Artist's Association.

  • Many thanks for this project. I have a friend working on a similar idea but nothing to do with a blind partner. You may well know this, but while a raspberry Pi would chew up a lot more millamps, it can readily aplay sound 'bytes' and espeak "text". I use the former to play train sounds and the latter to announce arrivals "The train on platform one is the 12:27 from Arnprior ..." I insert the actual time from an RTC into the text string prior to making a system call so it's always "ON TIME"'. I'm afraid this early movie only plays sounds taking cues from sensors under the track.:https://www.youtube.com/watch?v=jaF-1H7u_-w

  • Plexiglass is prone to expansion so I think there needs to be a gap between the edge of the 'glass and the depth of the slot to prevent buckling. Might be worth mentioning.For screws going into end grain, I often grind a small flat at the point so they cut themselves a thread.I too should make a set for the porch, if only the West side. It's a place I love to sleep, watch the moon and sometimes catch a firefly, but when nights are cold I have to wear a toque, or wet enough that I'm driven inside.My 2018 all-time record for July was 29 nights out of 31! The swimming was also good.

  • DavidW742 commented on fretters's instructable Computer Drawer

    I didn't make the computer box but I do thank you for the idea because I've had trouble getting at the back of my Debian PC which also runs a CNC machine. It's sort of cosy with the CNC Interface so mounting the PC on a slide box and screwing that to the bench just made it that much easier to access. I even remove 4" from the end bench so now I can get in and poke around at the back. My box ended up being 20" long, 8" wide and 4-1/2" high but the second-hand slides were just waiting on a workshop shelf so it all came together in a morning from scraps at the shed. I even found a brass handle!

  • DavidW742 commented on fretters's instructable Computer Drawer

    I spend far too much time struggling around the back of my PC even to taking a photograph so I could locate Audio Out etc. This has triggered two thoughts for my situation, one to simply mount the PC on runners so I could readily move it forward or secondly build a box like yours where the back comes out of the accessible LHS. My workshop even has a couple of slides pending deployment, mind it took a while to find them and they did need dusting off! As for lights ...

  • DavidW742 commented on BricoNosaureB's instructable Angle Cutting Tube

    It would be in the 60's I'd be working on these in drafting class working towards yet another A-level subject. That and sliced cones. Today I'd be trying to work something out using linuxcnc or openscad. I'm a far cry from cutting out anything as complicated as a turbine blade but am still intrigued by the possibilities. Thanks for the memories.
