One of the cats understands the concept after a couple iterations, the other one may never get it.
(The smart one is also trying to kill the goose that lays the golden eggs.)
Oh great. I still have the #catvideofeed to finish (a part is in the mail) and the #fpga tutorials to finish (and then to actually make some "devices" on there) AND a #neuralnetwork book I ordered myself on impulse, plus obviously all my "normal" life and work stuff.
PLUS NOW I've opened a tab to research a way to make a #diy #penplotter for some reason.
Thank you, #adhd, I have plenty to do right now!
(oh, maybe that could be related to the fpga circuit...? NO! BAD BRAIN!)
Wiring up a custom #sbc motor controller hat to power the #catvideofeed. I could use a #breadboard and terminal block, but let's be professional.
That said, the next photo will undoubtedly be of this in the trash because I suck at planning (#adhd) and will surely get this very wrong.
As if to confirm, after I took this photo I had the good idea to #solder some little "flags" near the first pins on things to keep me oriented. I put one of them *on the wrong side of the board*.
Put this aside for a week while I screwed around with other things. Today 5V #wallwart and #breadboard DC barrel jack came
Not sure I dare power the #SBC from the wart (polarity if I ever swap the wart), but can use separate USB there
Plugged the wart + barrel -> VOM to check which pin was what. Yep, 5V. Unplugged....1.5V for many minutes
How large are the caps inside these things? If I unplug it and toss in a bin, is there any chance of a short causing a fire...OR WORSE?
Motivated to get this project to a stage where it doesn't have to be on my workbench--I want the #oscilloscope for the #fpga (#adhd)
End-to-end test. Video fed live to browser. Click on the #video to start the feeder rotating, which dispenses some kibbies while Big Brother watches
Next step is to put this elsewhere, which requires power solution (probs wall wart). Then test the heck out of it to find the weak points. (Gonna guess the top struts and kibbie hatch.)
I'm frustrated. I have a pretty large #technic #LEGO collection and I had it all organized into little bins on a dedicated table for ~15 years. But the kids never used it and I needed that space for WFH.
Took it all down and used the bins for #electronics.
Two years later...I'm digging through a 20 gallon bin for each piece for the #catvideofeed mechanix. This is exactly why I organized it! Feel like a scrub.
At least I was smart enough to put the gears, axles, pins, etc in a separate bin.
At this moment, am jumping between these tasks
1. creating posters from maps
2. uploading map images to a printing service
3. #fpga tutorial video
4. #icestudio software
5. #python code for #catvideofeed
6. mechanics of #catvideofeed
7. lunch
Not sure why I didn't suspect #adhd before this...
Well damn. #LEGO is a little more effective than cardboard for building machines.
It isn't pouring yet and the structure needs some reinforcement, but this is going a lot better than it was.
@awesumsawz Right? One of mine was also to install a server room under the stairs with cable runs to all the rooms, when WiFi would probably have been fine. I'm a software engineer, not networking!
And now with the #catvideofeed project. This was an idle comment made by my wife and I've spent many an hour on it now.
But I learn a lot. And I feel ookie if I'm not accomplishing something, even if that something is "fiddling around with stuff that doesn't matter".
Having a lot of problems with my laziness-imposed constraint of cardboard #engineering. (I have a wood/#machineshop in the barn, but do I use it? Do I hell.)
After hacking a bunch of #Lego gears/connectors to fail to get the stepper turning the barrel, I wanted to build the structure out of Lego as well. Stepper now a problem.
You have Lego motors, nitwit!
Happen to have #HBridge ICs in stock, so threw together a #circuit to drive it from the SBC. Works! Now write a driver.
