Here’s a video on the idea of using a 3D printer’s extrusion capability as a means to doing injection moulding - using 3D printed moulds of course.
Ed, you might, or might not, find this interesting?
Ah, thanks, I see an event on morning of Wednesday14th August in Bath… as it turns out I’m busy. Interesting shape for an event though - up to 15 attendees and everything provided.
Come and face the challenges of competing against other teams and the fearsome house bots.
Build your own bot or use a pre-built one.
Work alone or in a team of 2
All equipment provided.
Participants spend about an hour learning to program the bot followed by an hour building improvements and battling the bots. For returning participants, as you gain confidence programming the bot you will be able to progress your bot with more sensors and spend more time building.
LEGO Robot Wars is a fun and interactive way to start learning coding concepts and a practical means to reinforce an understanding of Science, Technology, Engineering and Mathematics.
Here’s a nicely paced video about making a miniaturised steam engine - some interesting techniques and considerations come into play as you scale down.
Also notable, he 3D prints a 10x shape at one point, and uses a pantograph so he can directly trace the printed shape while controlling a tool which machines the tiny version.
Here’s a thing - a 3x3 decorated square with linked corners which can take two forms, decorated in such a way that both forms make a credible picture
Edit: not dissimilar and also featuring Steve Mould, a jigsaw with two solutions
I was most impressed! I’m guessing the chap who made the engine is/was a watchmaker?
By the way, has anyone seen Willard Wigan’s work?
FromeTechies, you might or might not find this fascinating?
I’m amazed and impressed at these lego sculptures - barely a right angle in sight!
“Pinball machines designed with only a pencil and pad” (plus drafting tools, I’m sure).
I have a confession to make, I sure was good (really good) at pinball (free games on a regular basis) back in the day.
