Hey Everyone,

Not sure if anyone cares, but if you watched my video you may have seen two texts on my tool box. Not sure how clear they were in the video but I forgot to post the links. I figured I'd just go ahead and post them here in case anyone is interested in picking up a copy! I got them used for fun and they helped me out tremendously, great reads too. The Karp text is a bit dense, YOU HAVE BEEN WARNED!

I provided links to the publishers but I know that PDF variants may exist out there in the wild  ;)

Ethernet the Definitive Guide: Designing and Managing Local Area Networks - Spurgeon

Would it be faire to interpret that second grapoh as saying that there is little point to make a contest longer? People will just submit in the beginning and end anyhow!
Potentially but there's no measure as to the quality of the videos. I think if the window was shorter you'd get a lot more off the cuff videos (Not that there's anything wrong with that, it's what I did lol  ;D).

So, who's the winner?

PICK ME, PICK ME!
I have the best lab and the best reasons to win, but I didn't posted a video!

P.S. My lab is ultra secret, so if I'd show it...

Will you take the text in the post also into account?
2 minutes is really sort to talk about all the usecases, especially like my video.

That's part of the challenge.

I tried to make a video on my project in under 4 minutes some months ago, it just wasn't possible.
So I know it's just impossible for me. Hell I cannot even fit all the stuff into one room, much less one take, so would have to buy video editing software too.

Even though this scope is on my must have list, I'm just too depressed to enter yet another contest I won't win for some daft reason.

Yeah, it's pretty tough if you've got something complex. I'm developing my own hardware and software with ARM processors, DSP, and PHYs, etc... I just had to do a high level overspimlifcation in the hopes I was getting the critical points captured.

You can always try next time!

Oh yes I watched your video and i only got like 10% of what you are doing :palm:

Do you design this stuff at home?

In my master thesis i musst interface an MII so at least i know whats going on there   :phew:

Yeah! It seems pretty daunting but honestly the biggest barriers for me were initially was trying to use BGA package types and the cost of boards that come along with them. However I found out chips like the AM335, TI Sitara processor that the beagle bone uses,  are actually offered in two packages: ZCZ and ZCE. The ZCE has a reduced IO set and fewer supply pins but the ball grid actually comes in a pattern that can be routed on four layers. I don't know what boards cost in your area but Advanced Circuits actually offers impedance controlled four layer boards for 66 US dollars for 30sq inches. This obciously has some restrictions like via type and no internal routes but still a great deal if you really think about your board and get the majority right the first time. I am very curious if I can have multiple pours for reference planes on one layer for different potentials, does that count as a route???  :-\

Then BGA aren't too bad if you practice a lot on them. My recommendation is to actually buy like 20 voltage translators or something for about 50 cents each and then practice on those, you can etch your own two layer boards dirt cheap to practice on too. Super easy and cheap to build a circuit to test if the connections are good, TI actually makes several fine pitch BGA packages for these parts that are tiny!

Yeah, and sorry the video was so fast, I hope it looked interesting enough to get the win! The DSPs I plan on using actually have MACs and switches built in that I hope to use. Then it can also do all the number MAC (operation) and send that off to the AM3358 that will control all the general operations and motors. I'll let you know how the media converter section works out too, just sent REV1 out to get turned, I got the one with no solder mask and it only cost like twenty bucks or something!

Sorry for the book,

Oh forgot to mention that the soldering I have to borrow a hot air gun for. Those VQFN can be a pain just like BGA. I luckily have some really good techs at TI to help show me the ropes. Lol, wherever you work, always find the good techs and buy them lunch, they WILL save you at some point!

What's your thesis on out of curiosity?

BGAs without soldermask sounds sick  :box:

I cannot tell much. My institute has a cooperation with a company.
But it's about automotive high bandwidth communication and the corresponding Protokolls (ab, ttethernet or tsn) for high quality of service.

This can also be useful for you. It makes Ethernet deterministic ;-)

I've soldered those (Sitara series) and written a programmer for STM32->Sitara hehe.

And yeah sub two minutes was hard. I covered like a sixteenth of the stuff I am involved with. Just thought I'd do the most recent ones rather than try and "prove" myself too much hehe.

Any advice for successfully doing such fine pitch or any headaches with the sitara chipsets themselves? I haven't tried a full chip yet, just other smaller inexpensive ones for practice.

Honestly when I do it I individually place dots of solder paste down with a pin head which takes about 30 minutes then bake it by hand holding it over an electric stove top.

Before baking though I mount the chip precisely using a drill press to very slowly lower it onto the correct spot and I leave a dollop of very sticky glue that doesn't seem to degrade that badly in the baking heat. The glue pulls away after quite easily but I usually leave it. If its a BGA pattern that has actual cavities then the glue is under the chip and it can't be removed obviously.

Lastly I leave a big dollop of solder paste very near the chip but as far from the edge that's most over the stove as can be and when it melts I give it a few extra seconds and remove the heat and just let it cool down on the kitchen bench.

If you're talking about the longevity of the board with baking times then yea that's out the window :)

Lol, I saw the video notification at 6AM when I woke up and just lept out of bed to see the new video. Had to go to work but at least we have a short tear down to hold us over.  :D

Honestly when I do it I individually place dots of solder paste down with a pin head which takes about 30 minutes then bake it by hand holding it over an electric stove top.


Huh, are the included solder balls on the pad not sufficient? I've used MG Chemicals' flux to hold the chips in place and then go through with a hot air station.

I have no problem paying shipping, and  fee's as it will still save me a great deal of money instead of buying this identical scope! Also check out group gets! We are selling our Wave-One 1GHz IOT boards to anyone who might want to create a low power IOT sensor network. PS: I rented the big brother of this scope for a few months; can't afford the price; and love the touch screen and simple interface. I do find the lack of high end current probs with self calibration (Like Keysight) an issue down the road. At my last job, I often had to use over priced current probes ($10,000-120,000US) to handle the 1200A we pushed at times in our circuits. As of right now I think I'll avoid those high currents... plus uA and nA are the new thing.. companies advertising "Ultra" low power... ;)
