Boards In Action
Log from Powerful Brushless DC Motor Driver/Controller
On this video I do a quick introduction to some of the Power PACk boards and how they can drive a small aerial vehicle motor. In this case, the motor was taken to 2600 Hz at 26V and 3.3A or so, which is in the 85W worth of input power. How much power...

Day 3: Y Axis
Log from YAPR
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...

Works before this
Log from Motor as Encoder
Using a motor as a rotary encoder is obviously not new. You can read the previous log entry to see how I was inspired.But every attempt I saw so far used the motor (BLDC, PMSM or hybrid stepper) as a generator, and measured the phase voltage looking...

5 Boards with Assembly are on order at JLC
Log from Brushless Actuator (Arduino-Compatible)
Size 50mm square and 58mm round On board absolute magnetic encoder is either MA730, MA702, AS5147 or AS5047 There are others in this range. Connectors clockwise from the top BLDC motor connectors & Power In/OutExternal Motor TempqwiicUSBEncoder SPIFan...

Mechanical Build - rear axis
Log from Electric Bobby-Car
To convert the bobby car to electric , I did remove the original plastic wheels and replaced them with 6.5" BLDC hub motors which can be found on hoverboards.First, I used a saw to remove some plastic from there area where the original rear wheels were...

Software requirements
Log from COSV - Cam Open Source Ventilator
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,...

First fully assembled leg prototype!
Log from NOMAD Quadrupedal Robot
Very exciting to finally get all the parts in and machining finished so that I could finally fully assemble a prototype leg. Couple of hiccups here and there but it will be fully usable for performance testing and the initial Shakedown cruise. Once...

[P] Chain in a channel
Log from Tetrinsic [gd0041]
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....

[EM] 580KV Motor Pad
Log from Tetrinsic [gd0041]
Before looking into the I2S implementation, I'm thinking that I'm getting more confident in creating electronic library components now and should actually make the BLDC motor pad instead of mentally remembering its existance. Not sure if the pins should...

[L] Expansion Pins
Log from Tetrinsic [gd0041]
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...

[L] 3DPCB
Log from Tetrinsic [gd0041]
This PCB looks cooler when all the vias are installed. It's easy to see that the ADC, encoder and BLDCC (BLDC Controller) are in a line for the aesthetic: It took a few tries to tweak the location of the "Tetrinsic" text since there's now a row of vias...

[T] Starting to think of a possible solution
Log from Tetent TwySize [gd0040]
I think part of the reason that I'm still cautious with #Tetrinsic [gd0041] -- even though I've got a potentially wearable form factor concept now -- is because a solution has not been computed for Tetent Tiny and #Tetent TestCut [gd0139] is...

Gate drivers and Hall effect sensors
Log from Gator Quad
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...

Prism spinning using feedback
Log from prism laser scanner
In short; - I am able to increase the speed of the motor using the hall encoders - prism speed seems sufficient for exposure ...

Assembly
Log from BLDC Variable Speed Water Pump
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...
