My 3D model brings all the boys to the yard!

And they’re like, it’s better than yours
Damn right it’s better than yours
I can teach you, but I have to charge.

Gotta Love Fusion 360. I should play with these models in dimension, but for now. Enjoy the progress on the Isodecahedron.

Building a Plant Cover

3D Printer HeaderSpending a little time making a 3D printed plant cover for my supervisor. A fun little project to distract me from the writing assignments I created this based on some memories of pictures and a rough dimensional drawing.

It will almost definitely need a few

revisions in order to make it a functional version.

One day project. Grad School Tracker

Well If you didn’t know I’m in Grad School… It’s a multi-year endeavor and occasionally it can feel like I’m making no progress as the goals are so far in the future.

So I made this loading bar using an adafruit e-ink raspberry pi hat and a raspberry pi zero.

It’s a fairly simple little project which will update my percentage complete every five minutes making a nice little distraction as the hours while away.¬†
Raspberry pi Zero with Eink Display
It will also act as a convenient fuzzy clock with the time displayed at each of the display updates. I may revisit this project a few times to add additional features and different display modes depending on the date or how far into my degree I am.

 

… I spent today moving my brother and his wife into their new place otherwise I’d consider adding more details…

Current consumption measurements

Today for work I needed to gather current consumption information for the Raspberry Pi Camera V2. Not in relation to the increased current consumption when processing the video for the system as a whole¬† (Which has been quoted elsewhere on the net as ~200mA – 250mA I cannot confirm this), but for the board itself. Specifically interested in the sensor the Sony IMX219, but making the reasonable assumption that the sensor represents the majority of the consumption in these cases. I’d prefer to rely on a datasheet but given sony saw it in their wisdom to not put power numbers in the datasheet for the part they left me no choice…

I found that the current peaks at around 40mA during the capture and the idle current consumption is around 1-2mA. These numbers are dependant on light exposure as a whole for the sensor with a noticeable difference in power consumption dependant on whether or not the sensor is covered. These measurements were taken using a 121GW multimeter to measure the current while streaming the data to my phone, the Camera module was hooked up to an older Raspberry Pi A. I melted the covering and placed the ammeter in-line with the power rail for the camera module. I measured the rail at the expected 3.3V

 

Hopefully, someone else can find a use for this.

Old Projects from the Early Days

I’ve been doing various small projects since my first year in Engineering but haven’t previously had a place to post them anywhere but my youtube account.
