Hello Rebels!

I use CAD at work all day and recently a new drafter was talking about getting a custom macro pad called a streamdeck. The thing is basically a tablet with buttons on top so you can change the button icons to anything based on the application. While that looks cool and all, I encouraged him to try his hand at building his own macro pad with an arduino. As it turned out, he was not super interested in it, but at that point I already started working on one myself.  ;D

I found a 4x5 keypad on ebay that came with a plate, switches, and clear keycaps to make your own symbols. I used a pro micro, rainbow wire, small signal diodes & brass wire to make the mat...

This tool finds the relationship between servo pulse time and rotational angle. A simple brief that uncovered a number of tricky issues.

When constructing any robot that moves, work has to be done to define the movement. If using pulsed servos then this ‘definition’ will likely be in µS and quite specific to the actual motor. Should the motor fail and be replaced, or a second bot made, then the definition will no longer be accurate.

Calibrating each joint in degrees, rather than µS, will remove the need to redo the original work.

So an optical shaft encoder is coupled to the joint ‘axle’ to act as an electronic protractor. Then a rotary switch is used to manually find the mechanical limits of the joint plus ...

As we are supposed to learn from our mistakes I have written up one of my failures.

The project was to build a bot, as cat like as possible, to sit and wave a paw, stand up and walk around.

The activity started more than three years ago with an attempt to copy Boston Dynamics’ quadruped - Spot.  Believing the quoted torque values was the first mistake as the 55g servos could barely lift their own weight. The leg modules were later re-used for HybridTrotter and Scooter Boy where they provided the drive but the weight was carried on wheels.

Using a Picaxe micro, Hybrid Trotter was posted on their forum and the video shows a disinterested Meowth idly watching. A spirited Am...

Hello Rebels!

Intro aka The why

I gave in!
After all my more or less custom builds: clunky Mendel, the Hugo based Bumblebee, Acryl, The unnamed delta, The Foosa, The very secret secret one.... I've managed to get frustrated enough by recurring printing issues, cheap parts, experiments, experimental firmware and ended up having a semi functional Acryl which still need a lot of the aging parts replaced and probably a new hotend too.

So I gave in and ordered an "Original Prusa I3 Mk3" printer kit. It's somewhere in Budapest at this time on it's way to Romania where DHL estimates it will  be delivered by Wednesday.
Considering the kit price of almost 800 Euro I cannot call it cheap compared to ...
