Oscilloscope testing

I got this Rigol Oscilloscope last month and finally got around to trying it out. Figured I would try something simple and measure the echo pulse on this ultrasonic distance sensor.

The pulse measured 475.5us, dividing that by 58 gave me a distance of about 8.2cm

iPad Pro 11″ Bumper 2018 with cutouts for speaker and microphones

The Ruiz Brothers made this real nice case for the iPad Pro 11″. I have been using one on mine since I got it. But it was missing the cutouts for speakers and microphones. I was able to find the Apple Accessory Design Guidelines and get the dimensions and placement of these items.

Using the Fusion 360 files provided in the Adafruit Learn Guide I was then able to add these features. My remix of the design is available on Thingiverse if you would like to print it.

Stickvise Jaws for an Adafruit Circuit Playground

I got a Stickvise a while ago. Its a simple to use low profile pcb vise. The great part about it though is that its hackable. You can create your own jaw designs for it and attach them. The website has a hack your vise section.

I used the provided specs to make these jaws. They allow me to hold an Adafruit Circuit Playground board. This gets the board off of my messy bench to prevent any shorts. I designed it in Autodesk Fusion 360 and printed it out on my Lulzbot Taz 6.

Bluetooth camera slider remix

I built a bluetooth camera slider following this Adafruit tutorial – https://learn.adafruit.com/bluetooth-motorized-camera-slider/overview. But I wanted to improve the design on the bearing mount and the camera platform. This video shows the changes I made in Fusion 360.
