DoubleJoy™!? PCB + 3D Printed Case Design & Build

[@tomlynn1000]

I've got to say your videos are so much more fun when things go wrong rather than perfectly.

[@RetroRecipes]

I'd tend to agree!

[@jwilder2251]

What would you do if you had a million dollars? Perifractic: Two Commodores at the same time, man

[@electronraygun6346]

Damn straight. He always wanted to do that, man. And I think if he had a million dollars he could hook that up. Or even if he didn't.

[@silmarian]

Puppyfractic has a good "mom, dad, stop fighting!" look

[@RetroRecipes]

She really does sense it!!

[@MikeWood]

Two things. Switching the ports to the underside of the board was a clever work around. And you appear to have soldered before. Some really nice work. and re work. and re-re-work. :)

[@RetroRecipes]

Thanks!

[@janikarkkainen3904]

Yay! It's entertaining (and somehow also comforting, you realize you are not the only one to bang your head on the wall constantly) to watch other people struggle with electronics projects, but it's also really nice to see a happy conclusion to a project! Well done!

[@VariXx]

I love "because why not" projects

[@swamihuman9395]

I LOVE PUNS! "The only bad pun is the unattempted pun." ~Swami

[@dwegmull]

Don't feel too bad about the inverted DB plugs: I've seen professional engineers get it wrong too. One more thing: in the quick glimpse of the schematics, it looks like the input of the unused gate is left unconnected. Depending on which logic family you're using, it could increase power consumption and/or oscillate which could inject noise in the adjacent gates. It is considered good practice to ground any unused input. For a prototype, the grounding is often done through a resistor, to allow using that gate if it becomes needed during debugging.

[@lorinmillsap5372]

David Wegmuller the unused gate is grounded.

[@electronash]

The board looks good, and the 74LS07 buffers are the ideal thing to use, as they have the open-collector outputs (as described in your previous vid). But I would definitely recommend adding decoupling caps (0.1uF / 100nF) close to each chip. Without those, it could be allowing some noise, and possibly causing some oscillation. Don't worry about the mix-up with the connector types. I've done that before. lol

A fun thing about those diodes you used is they can be used to build very effective crystal radios. If you ever want to expand your viewership with just some shielded copper & one of those & maybe a 3d printer, it'd be an easy project. Bonus points for different coils for different bands. Like the VEF-206 you whacky Brits imported from the Soviet Union in the 80s.

[@RetroRecipes]

Thank you young Padawan

[@VictorKorp1999]

When you were desoldering the db-15 connectors, it seems to me that it needed more flux in the pins and a good desoldering mesh to finish removing the remaining ones. It is a constructive contribution, do not take it wrong, your videos are excellent and the contribution of the adapter for two controls too :)

[@RetroRecipes]

Thanks. You're probably right but as I said, I was getting impatient after too long spent on the issue ¯\_(ツ)_/¯

[@ScoopDogg]

I'am impressed and how I miss those Alan Partridge episodes on TV

[@00Skyfox]

You make this stuff look easy! But projects like this do show how important it is to double and triple check pin outs. At least it was a very easy fix. If you sell the boards or plans, you could have the silk screen indicate that male ports can be put on one side, of female ports can be put on the other side, so the end user has the option.

[@RetroRecipes]

Yes, the board layout is free via the description and I'm pretty sure we marked them.

[@davidcox1508]

Peri and Lady (and Puppy) Fractic, I've recently come into possession of an Atari 130XE Computer (American - NTSC). It's my THIRD. It's in BEAUTIFUL condition, a real TREASURE. Unlike my two OTHER 130's, when coupled to my S-DRIVE MAX, I often get a message saying "REMOVE CARTRIDGE" when trying to load certain games or programs. ODD! I don't get this error when loading from my OTHER two 130's, but this one's self-diagnostic shows no problems. I'd be more than HAPPY to DONATE it to you and the lovely Lady Fractic, if you can SOLVE its problem, and add it to your 'happy' library of history's working machines! I'm not NEW to ATARI Computers - owned my FIRST original Atari 800 in 1982, and my Atari 800XL in 1984 - my first 130XE in 1986, and my first 1040ST in 1987, but have never encountered anything like this. If you can pull this 130XE apart and discover what's wrong, this machine is YOURS! It's a 'Beauty'! I just need to know where to SEND it - maybe you have a new 'episode' on your hands!

[@RetroRecipes]

[@RobA500]

Nicely done there sir, even if you did get your males an females mixed up. Nice to see you crop the resistors legs before soldering, so many people still get that wrong. Looking forward to some double play competition. 👍

[@Wizardofgosz]

Meh, the only leads I crop before soldering are caps and things with thicker and longer leads which really do act as a sink and make it hard to solder the joint properly.

[@RobA500]

Richard Wielgosz the reason you should crop before is because you can cause fractures in the solder joints doing so after. They may not be seen but can become bad later.

[@Wizardofgosz]

@@RobA500 interesting. I've never heard that mentioned before and I've been Soldering for more than 40 years.

[@atari2600b]

You should learn the drag tin technique. That's where you tin the iron tip, then you bring them both in to pin 1 & simply drag them both down the line. If any of them bridge you just drag the iron again

[@RetroRecipes]

I've tried that. I find the cleanup after takes almost as much time, but maybe I'll show it.

[@Santiago_Handle]

[@RetroRecipes]

Thanks Sean. I appreciate you recommending such a great piece of software. 👍🕹️

[@OperationPhantom]

The very excellent adventures of one man and his joystick. Glad you got it working in the end. Interesting (and weird?) to control 2 different machines with the same stick. Now for something completely opposite. I've actually wondered for some time (I'm non technical BTW) if it is possible to build a splitter cable that goes into port one of the Mega Drive / Genesis and on the other side, has connectors for a Master System controller and Mega Drive controller, so they could both be used when applicable. Because the MD is backwards compatible with the MS but you NEED a MS controller for certain games. I believe there is a solution where you cut a connector in the MD pad or something but it would be neat if a splitter cable existed that was "plug & play".

[@actuallyusingmyrealnameher5061]

If only I could double the efficiency of my joystick so easily 🙂

[@DrTofu83]

LOL, I remember having a TV set similar to the one in the opening sequence. Actually, my parents had. A Philips based on the KT-3 modular chassis, one of the latest with the band set by potentiometers that became my first best monitor ever when I got tired of my CM80. You always bring me down the memory lane, thank you!

[@RetroRecipes]

You're welcome. I think that's a Philips but we rebadged it Hinari as that's what I had as a kid :-)

[@DrTofu83]

@@RetroRecipes Well, it's just that I was seeing your vid while trying not fix my current favorite monitor and it popped me on mind the KT3 Philips chassis, which is very similar. Seems it got used a lot during the '70s and the '80, with just slight adjustment to accommodate for upgrades (the first units had pots, the later ones a primitive setup). It's funny how some details give you flashbacks :)

If we could all follow your lead what a wonderful world we would live in. I remember playing my old Atari with a similar joystick and blistering my hand between my thumb and forefinger. These joysticks were built to last!

[@RetroRecipes]

Thank you for your kind words! Means a lot 👍🕹️ Yes, self taught, ironically by watching KZbin videos too 😂

[@sebastianracedo1636]

If there is the possibility of sending this information via Wi-Fi, this dual joystick could be used in several things. One port would go to the computer, and the other port that communicates with it would be a Wi-Fi receiver. I know it's crazy and it will depend a lot on ping. but if you play with people from the same region and you have a ping of 20 or less ... there would be practically no lag, it would be a way to play with 2 real computers online.

[@RetroRecipes]

Nice idea. That would be _very_ tricky to get right. You'd each need one, would both have to start the game at exactly the same time, and so on... Interesting to think about though.

[@stefankrause5138]

Well, the fact, that a design-failure in the PCB needed to be worked around gives this thing kind of the touch of an authentic Commodore-Herdware-Product. ;) P.S.: How abouta sync test of the original SX64 vs. the SX64-mini?

[@RetroRecipes]

[@TheNews1990]

Just a thought... Can you hook this up to 2 SEGA Genesis consoles, and see if there's any input lag between a model 1 & model 2?

[@RetroRecipes]

Sure, when are you sending them over? ;-)

[@Spritetm]

Great video, as always! Can I ask why you went for buffers, and not e.g. electrically controllable switches like the CD4066? in the end, what you want the computer to see is a bunch of switches, and something like a CD4066 would emulate that perfectly, while something like a buffer always runs the risk of putting a high voltage (when the button is not pressed) into the computer. The 1K resistors probably lower the chances of that being an issue, but the risk is always there; additionally, the 1K resistors could attenuate the button presses and make them not register on some computers. Maybe something for v2?

[@lorinmillsap5372]

That is actually a good suggestion. The 1000 ohm resistors shouldn’t cause issues on 5v systems but could be too high on a 3.3v system. The CD4066 would probably have been a better choice, but I’m not a professional. I just jumped in and helped because I could.

[@RetroRecipes]

Luckily I don't have any "current" plans to use a 3.3V machine. I actually doubt it would hurt but that's just a hunch.

[@onewheelpeelproductions470]

So I only need to use one old computer at a time, but I get a little frustrated with how the old C64 games don't all use the same joystick port. It seems this could be plugged into joy1 and joy2 on a single C64 so that I'm always set up. BUT that might be an issue with some two player games, what do you think of a version with a toggle switch to flip between activating J1 or J2? Future video idea? Yeah its a first world problem not wanting to manually swap the joystick from J1 to J2 I know.

[@RetroRecipes]

Well you wouldn't even need the toggle switch, it should just work as the C64 game would ignore the "wrong" joystick port (otherwise that port would've worked).

[@droopysloopy]

At backbit you can buy a device to use one joystick for the two ports. Can switch automatically or by hand (without shutting down the C64).

[@RetroRecipes]

I wonder if I couldn't used that for this project... Or maybe it's just a switch and only goes one way.

[@onewheelpeelproductions470]

@@RetroRecipes Some games use both if two player, but say for example its waiting on player two to press fire on the second port, so the game would falsely think I have a friend playing the game with me. Hah like that ever happens!

So fixing the schematics so it is all on one side of the board?

[@RetroRecipes]

Yup, done and in Description

[@rdoetjes]

I always get shivers when I see someone first solder the leads and then cut them -- and not reflow. This is a recipe for disaster a few years from now. Because when you snip, you send a shock wave through the weaker solder going opening it up for air and elements that can cause corrosion and/or expanding and shrinking by heat and that's when solder joints fail. In engineering college we had a teacher who'd build systems for satellites and he was shouting at us when he saw someone do that and ridicule us :D It's absolutely not done in aerospace industry. So I never do it or when I'll reflow the joint -- and it makes it look nice too. We also had to put our dips in without sockets (unless it was expensive -- the hypocrit) because in aerospace the frequent G forces could life an IC out of it's socket -- and apparently it had in the past and made a multi million dollar satellite become a very expensive paper weight :D) But I do like my sockets and I am not shooting my stuff to orbit around the earth :D But the solder joints is something that is very useful knowledge also on this globe.
