To conceal the rough ends of the rails, I covered them with printed end caps, which also act as belt tensioners. The belt brackets are fastened to the end caps and tightened using M3 screws. Afterwards, I fixed them to the rails with more M3 screws...
The platform is built upon a custom modular 3d-printed actuator, with a 8:1 planetary gearbox. The dimensions are 47mm x 47mm x 47mm, and the cost is about $74 per actuator. The BLDC controller board it uses is the DrizzyServo from dizzy.ai. I also...

Outputs Generate step/dir for controlling a stepper motor, or generate PWM/dir for controlling a BLDC motor or standard DC motorFor the prototype, the current motor is a stepper. The end goal is to drive the BLDC motor. Software generates a trigger,...

Before moving on to the Assembly part, you first need to know the components that we are going to use to better understand what you are doing. So, let's discuss the components one by one:- DJI F450 Frame: The frame that we have used is one of the best...
So I'm looking for where I misplaced my tin foil box, and I see something in the bag of TCT360 goodies I got months ago:It's a peek print on a metal ball chain! And, conveniently enough, it's the size I've been using for the current Tetrinsic redesign....
So I've looked into the TC358870XBG and it seems that 2 I2C pins, 1 reset pin, 1 clock pin and an INT pin is needed. One probably could make a circuit that generated the clock instead of the MCU, but a free pin is cheaper than that. The main issue...
Hey, anyone have advice on driving high voltage brushed DC motors? E.g. treadmill motors or the lovely old ones that last forever if you change the brushes out? They are available for dirt (I got 3 for $15 each! Working!) and yes, I know the new BLDC...
Today I accomplished two main things. The first was quite simple. I was able to get the gate driver IC's mounted to the SOIC-8 to DIP-8 breakout boards from sparkfun. The second was to determine where to place the hall effect sensors to meet the needs...
So you've made it this far with me. It's time we assemble the beast and bring Franken pump to life! This was a very straight forward assembly almost boring perhaps. Surprisingly there were absolutely no major issues with my designs and subsequently...
The Power Stage Variations The reason why PowerPACk32 was designed as two different boards was to make it easy to deal with the different topologies. Although a 2 board solution is often undesirable, when experimenting there are a few advantages worth...
So here's something the average build does not have: A thread running in the background continuously checking the integrity of the flash memory! So while your high performance powertrain is crunching numbers, running a 30kHz control loop, communications,...
Detailed technical description: (ax1 is the base rotation, ax2 the joint just above it, and so on...) For control I use 5X Teensy 3.2 microcontrollers, they are connected together into a single CAN network, (Odrive is also on...
