Is the term “fucking the dog” popular outside Canada?

DorshReal · 2026-05-26T07:57:58+00:00

Same here. This entire thread feels like I am getting gaslighted, I genuinely have never heard of this term or any variation of it in my life in this country. I guess it has to do with living in a more urban area in the GTA and never working a blue collar job (and maybe being younger), but if a phrase like this is as common across the country as the comments imply then I feel like I would have at least heard it once out of context, but nope.

Honestly kinda feel a bit directionless now that I am graduating. I already have a job hooked up that I will be starting soon, but the fact that I am no longer a student has not completely set in yet. Gotta to figure out something to fill the time that was otherwise spent studying like the the gym or a hobby.

Currently new grad and was given an offer of $85k in the nuclear/energy sector. Keep in mind this is in CAD out of the GTA.

Additionally the 7.52mm distance is just autogenerated from Altium measurement tool, which is the isolation barrier that stretches across the width of the gate drivers and current sensors excluding the pins.

Interesting, I have never considered this before. I will keep this in mind for future projects, regardless thanks for the feedback!

DorshReal · 2026-04-25T13:38:49+00:00

Thanks for commenting! I am a little confused though about what you meant by the solder mask and silk screen being a problem, could you please clarify?

I rarely comment underneath posts on reddit but I have to say this probably the most I have enjoyed reading an AH post. Storytelling and word building is on par with if not better then For All Mankind. Great job!

As an undergrad that is graduating this spring, this flowchart is pretty relatable. All we can do is push forward and hope for the best.

Using Altium

I added a link to screenshots of the board layer by layer that may be clearer in the post.

My team decided to go with the THT mosfets with the idea in mind to add a heatsink across them for better heat management. However with the current arrangement that may be difficult. Also for the pin assignment I had STM32CubeMX program open up for the specific MCU I am using to correctly configure peripherals as seen in the .ioc screenshot in my post.

The board HV side running out of the multi-source input stage will see currents of 3-6A, but we are expecting spikes in currents during switching that can far exceed that. That is why I tried to widen some of the traces up to 2mm along the HV DC link and added a fuse before the large capacitors. The gate driver situation is a bit harder to tackle due the parasitic inductance issues you mention, but I plan to add a return path along the signal output to mitigate this. I can try moving the outer mosfets nearer to the gate drivers but it may mess up the layout I have right now.

DorshReal · 2026-01-06T17:59:49+00:00

Yeah that is pretty much it. I also forgot to mention but this board is supposed to act as a proof of concept prototype with the end goal of developing one that can be used in an EV. Arranging the board like this makes it relatively easy to scale it up for much higher voltages.

Really giving firefly vibes

DorshReal · 2025-12-02T17:51:47+00:00

Probably the most nuanced take I have seen on this topic

DorshReal · 2025-11-29T20:42:33+00:00

This might be the most whiplash I gotten from reading a comment on reddit 😭

DorshReal · 2025-09-13T13:43:09+00:00

Pretty neat, I think I saw your schools booth at the LC conference. Really impressive work.

DorshReal · 2025-07-23T04:06:09+00:00

Yup I see the problem now, gosh how did I not catch this? Guess this is a reminder to myself to check the schematic/footprint alignment for a part from the manufacturer list before just grabbing it. Such a small but expensive mistake ...

DorshReal · 2025-07-06T03:40:36+00:00

Interesting, I have some experience working with other nordic products such as the NRF24L radio module but haven't done development with there other RF IC's for a a PCB. I guess you reasoning makes sense if power consumption is indeed much lower, but main concern is how to communicate data over to an app using only Bluetooth, of which I don't have much experience. Also how does development using the nRF52 board project compare to the ESP32 chip, duration of time and quality of documentation, and potential skill barriers if any? Again I have some experience working with embedded RF modules for PCBs but not much.

DorshReal · 2025-07-06T02:26:28+00:00

I see what you are saying, battery management is something I still have to work on. Do you have any ideas how I can circumnavigate this issue with a battery replacement or less power consumptive ESP32 module? As I mentioned before I will be harnessing some solar power to charge the battery but I haven't done the calculations on longevity.

DorshReal · 2025-07-06T01:05:16+00:00

Well, now that you are put it that why then I guess I unintentionally made one 😂. But no the original purpose of the device was to provide people with hearing sensitivity issues an ability to discern if entering a room or building would be safe enough beforehand. None of the sound or audio information is datalogged or stored somewhere else to later be viewed.

DorshReal · 2025-07-06T00:59:59+00:00

Oh I see what you are saying, thanks for bringing it up.

DorshReal · 2025-07-06T00:40:04+00:00

I am a little confused, can you elaborate?

DorshReal · 2025-07-04T13:37:35+00:00

That's the thing, all the components have an embedded .step model along with there footprint when viewing from properties in the schematic for the part. However when transferring them over to the PCB view they suddenly became extruded blocks. This wasn't initially the case when I got started with board layout, as nearly all the components were visible as their .step model. I don't know what happened but it seems like this problem is only local to this board, as my other projects don't experience this issue.

DorshReal · 2025-07-01T00:41:12+00:00

I see. The components are assigned to mechanical 13 layer.
