It's very rewarding to watch your systematic work and reasoning during the whole construction phase. From idea to the final tests. Well done James, well done 🙂

Nice one, James! I'm laying out my own board (USB SDR interface), enjoying a beer, and watching you layout a board! 👌

I'm the same, if something on a PCB ain't right it bugs the hell out of me. Great work James !.....cheers.

Loving that your signature in solder is so complicated. Lol

Terrific. It's getting very exciting. Thanks James. Take care.

Excellent work! Those cosmetic touches make all the difference!

It’s amazing progress

Love the LED layout!😁

Yay, another James video. According to the dates of the comments I really should become a patreon. Never be ashamed of bodges, have you seen the 80s mass produced computers? Many with factory made bodges for months or even years. Bodges are just a part of making new computers.

So great to see Snek being played with the controller, with PCBs completed. Glad you took the time to fix LEDs...that was so frustrating to see that happen, but that's what revisions are for :)

Love it - totally agree that the layout had to be fixed. Also... 20K! Well done!

Awesome job as a always .....

PCB bugfix was totally worth it for the joypad silkscreen alone.

Just so cool and mad respect!

The outline is really good. Another little board to your collection

Nice looking board James. Don’t forget to add the missing link to the backplane schematic and layout now, because when you come to make an integrated backplane that correction will be easily forgotten. Ask me how I know these things 😊

I love it.

I like to complain about PCB designs people do, so let's go... 1. Don't leave copper pours with single via (32:52) - it acts as antenna and your board becomes a nice radio. 2. Traces / components should be at least 2-3mm from boards edge (with exception for angled connectors) 3. Board edge should be protected by chassis ground ring (on each single layer) that is stitched together with vias. This reduces edge fired emissions. 4. Thin long ground pours also acts as antennas (ref. point 1, 32:30) 5. Components should be placed at least 1mm away from other components in low density designs [34:12, capacitor and SOIC14 IC] 6. Each PWR/SIG via should have GND via placed at lumped distance - it improves signal integrity and is necessary at high frequencies (and in power-spike-sensitive circuits) 7. In two-layer designs never cross signals at angle other than 90 degrees (bottom/top layer). Otherwise they will couple together causing interference. 8. If you've space use that space - place traces as far away as possible. 9. Always name your nets (makes it easier to understand your work when PCBs arrive :D). 10. Use colors - it makes routing way easier (especially to have custom color for each power network / GND and high speed signal or parallel bus). There're other issues, but those are the most significant ones. Your design is not bad (as it's low frequency, so it works fine. It's just an "future problem" pretender - it's better to learn proper design rules from "beginning" than to implement them later on).

I love that your hotplate still tries to display "Err" when you shut it off.

Great videos. Is it possible to use solder paste without a stencil? I have a smd practice board but it hasn't a stencil

Not so bad. I am sure I would have needed more versions of that board if I would have done this. And maybe more layers, too.

Bedankt

Great! Will you convert this interface now to become an SPI device as well?

Morning James, any reason why the final peripheral back plain there couldn’t be more than one SNES input board for multi player games, should any arise that is?

If you have silkscreen on bare copper, they will not silkscreen print that, so you could have let it like you had it the first time. No use for that information now, but good to know for in the future ;) Nice build btw!

Huzzah! This is a great step toward making a retro style game console, that's also a general purpose computer with a tty. I wonder what it would take to make an emulator for this board, once it's all said and done. That would give people a reason to write code for it, and you could run it on hardware (as well as anyone who can be bothered to duplicate your boards). I'm not suggesting you write it, but it would make a cool project. Imagine if you had a C compiler back end as well.

How can you concentrate on the game when there are all those awesome twinkling LEDs?

My youngest daughter got married on Saturday, I had a horrible chest infection since Saturday and now that I feel better I see this gem of a video in the series and all is well!

If you put a polarizing filter in front of the light, and another one in front of the camera, rotated 90degrees, it might help reduce the reflections? Honestly though I don't think it's that bad, at least not in this video.

Blast Processing (TM).

I really dont like the select and start buttons being so high up. Ideally they should go below the Right and X Leds. But thats only cosmetic (and will forever trigger my ocd). You might be able to squeeze the 3 lines going through the perfect spot in between the led pads.

Oh noes! Glad you respun the PCB. Don't be too hard on yourself. This stuff happens. Look in anything electrical you've bought - bet the PCB isn't V1.0!

Your circuits are very hard to follow where they are just shown as individual chips and a global label. Have you thought of using a bus so you can follow the flow more easier. Would help with debugging the circuit as well?

Planned Obsolescence ?

Oh bummer, that really sucks Well you have to have a failure at some point but at least it wasn't a Magic Smoke mistake.

Is better to learn playing with the buttons reverse and the absolutely dominate when your friends come over for a gaming session.

37:54 what is going on with the JLCJLCJLC and their serial number? They didn't replace it? 😂😂

Only at the beginning, really wishing the abxy buttons were in the same location, but rotated to make the two // shapes on the controller.
