Cory spend the week working on the green head and came in with it this much progress today:After that he added the teeth:Then a new member showed up with an unexpected surprize, a functioning claw!Cory seemed pleased.finally we blocked out his profile...
When the controller and the housing are assembled the wheels can be placed. Therefore the gears with 8 teeth (6 pcs.) and 12 teeth (2 pcs.) need to get equipped with a brass axle. A 3mm brass rod can be used for this and will stick well in to the gears....
A few months ago, I tried creating copies of my home keys in SketchUp. With a few iterations and eyeballing it, I eventually got something that slide in and out of the lock with ease: It slid in and out of the lock pretty smooth, so I upgraded,...
Well, it's small. Too small. I thought that skateboard bearing looked huge... I had messed with the number of teeth on the drive sprocket earlier. The design is parametric so the tooth count, being bound to the fixed parameter...
Finally got around to generating a version where the input and output gear pitch matches the corresponding layers, aka split planets. Here it is, with a twist.I generated the above with zero backlash allowance, just to make sure all the teeth were...
Version 1.0 used a Deep Grove Ball Bearing instead of a Cross Roller Bearing. I just want to see how good the gear teeth meshed with each other.This is the tooth template I used. It's a double arc profile for additional rigidity of the flex spline.*Source: https://www.harmonicdrive.net/technology/harmonicdriveAnd...
I'm cutting my teeth in KiCad and have the schematic created and the board outline getting ready for routing. Latest state of the files are updated in GitHub.I need to review the schematic and footprints closely before diving into the layout. I'm excited...
Even better than PC board pliers is a stand for dunking them. Lions always used surface tension to float the boards on the acid, but this should eliminate air bubbles. Helas, the pliers now need a place to put a rubber band & a place to clamp onto the...
Started by setting up a Theme and a GUI concept.Also I started to design the Getting Started walkthrough. Very unhappy with the pictures I do have but at least I have some. Next step is to draw the wiring schematics for every Breakout Version. I know...
There is plenty space available in this box ! The raspberry-pi and camera module somehow looks funny.The back button and main power connection.The printer, and front button.
As per the last project log, I've moved the internals to a larger enclosure.Inside... plenty of room for future projects...Connected up to a Pi acting as a terminal via minicom...That's all folks!
Yes, finally. You can play pacman on the Moncky computer!This game was written in the Moncky programming language and compiled to Moncky-3 machine code. It is about 20KiB. So plenty of memory left!You can see a video on:
Today i split my time between Ruperts body and my animatronic head. First i added the eyes:Next i cut a strip of foal the make the matching top and bottom teeth:the attached the top:And nearly decided to stop there and make him have an overbite. Instead...
So I finished up the design, it's a bit bigger than 1.5" if you include the housing :P but I'll give myself that one for making something that honestly is pretty darn awesome if I may say so! I haven't really had time to try to fix my drill charger or...
To see if the idea works at all I started with a quick build based on Fischertechnik and some hot glue. The small Fischertechnik gear "Riegelscheibe Z20" fits perfectly on the 4mm part of the Luer connector. It is actually a gear with 20 teeth, modulus...
