Building a TZXDuino & How to program (or Update) the Firmware!

[@thepenultimateninja5797]

I agree about the loaading screens being an important part of the experience. As a matter of fact, when I use an emulator, I turn off all the fastload features. I had a sort of epiphany when I was showing my son what video games were like when I was his age. I made the tape image load in real time on the emulator so that he could see what it was like loading a game. It was the first time I had ever done this with an emulator, and it sort of made the experience feel 'right'. I leave those features off all the time now. Loading games in real time makes even an emulator feel authentic, and I find I'm more likely to persevere with a game instead of hopping from one game to another.

I like the idea of using a breadboard to hold the header pins. I would never have thought of that.

[@louispole6285]

It's an idea as old as dirt.

Actually paused the new LGR vid when I saw this one pop up in my notifications! Can't beat a bit of MFS.

[@MarkFixesStuff]

Don't tell LGR! Thanks Chris!

I love this kind of videos and obviously your channel! Greetings from Paraguay!

[@MarkFixesStuff]

Awesome! Thank you!

[@thesadken]

Has it really been 7 years!!! So much us changed with them since then 😁 Zaxxon did a nice job with his pcb design, and fixed the issue really quickly.

[@dreamvisionary]

I bet you'll be glad when you've finished that reel of solder :D

Watch the next video ...

Spoiler: The butler did it! :-D What, people, did you think i was going to bugger the next video for him?

Registered copy of WinRAR. The first I have ever seen in the wild..

I was drunk.

[@murrij]

lots of good tips in here even though I don't have a TZXDuino. Thanks Mark!

[@SidebandSamurai]

I love the "Smurf poo" and I also love the basic electronics you give with your soldering a project. You get a like and a subscription for that. My wife is studying armature radio, she might find these videos helpful.

[@MarkFixesStuff]

Thank you so much :)

[@adilsongoliveira]

I found the other one! I do also have a registered winrar and thought was the only one! My brother! 😁

Nice step by step process thanks.

Thanks Mr Edd!

If you don't like al the hardware fuzz, start with a microcontroller with built in display, audio and SD slot.

Great video Mark, all the best with the channel.

[@MarkFixesStuff]

Glad you enjoyed it

DOOD! Gummies!

[@MarkFixesStuff]

They barge into loads of my videos!

[@DAVIDGREGORYKERR]

You could build the firmware binary from the C++ source code and build it using Code::Blocks with the AVR toolchain which includes avr-gcc and included files.

[@TEBLify]

Boo I tell you, should have used [insert massive plug here] instead! Excellent video to round off an evening without soldering anything myself 😀

[@MoreFunMakingIt]

Is that mercury core solder? Great video Mark.

[@DAVIDGREGORYKERR]

I was just wondering if games were saved to tape on a PHILIPS DCC900 the games would fail to load because of the PASC compression stripping data out of the signal am I right in thinking that.

[@SelfIndulgentGamer]

Call me lazy, but when checking out the project on PCB way, I can't work out how to get it as a bundle. Is there a way to buy it with everything included? Thanks :)

[@MarkFixesStuff]

Sorry mate, but no.

[@MultiBear101]

HI Guys, I am a little confused about the functionality of this gadget. How do you save a program from your ZX-whatever to the TZXDuino? Thanks in advance

[@alexstone691]

I feel like you have experience with soldering but oh god why are you using that tip and you should definitely get either gel or paste flux, it works so much better and doesn't drip everywhere, i personally just use solid rosin and dip my iron into it when doing things like this, but you can also make paste by mixing it with acohol

[@MarkFixesStuff]

I've got rosin based paste flux. It's fine and works well but it's SOOOOO sticky to remove - even with IPA. This Topnik stuff is excellent though. It's for SMD but I use it for all sorts. I must admit that the running flux is a bit of an "on camera meme" for me though... "loads of lovely flux" etc. What do you do about sticky residue??

[@borayurt66]

Old bootloader is too long, like 2K, new one is just 512 bytes, leaving more room for the sketch. You can easily upload it to the Nano via ICSP header and an AVR programmer (or another Arduino loaded with Arduino as ISP sketch). Last time I checked, TZXDuino defaulted to an OLED screen and some changes in the code were needed to make it work with 2x16 LCDs. Seems like you did that off camera or does it come with 2x16 as default? You should also check the MaxDuino.

[@MarkFixesStuff]

Yeah. I just wanted a simple process for first time builders. The 16x2 display comes on as default BTW. Sometimes you need to change the adress of the screen, but not in this build.

[@lovemadeinjapan]

@@MarkFixesStuff If you use a 16x2, get a white on black VA one with built in I2C. It doesn't have the total shythe readabiltiy, and it is a hassle less as the I2C is incorporated. Cheaper too than those stinking blue ones with a backpack.

[@msackett4858]

Hi Mark Excellent video its got me inspired. Do you know where i can get a TZXDuino Shield, ive tried your link but no luck, or is there any other pcb i could use.

[@MarkFixesStuff]

Hi! The PCBWay link works for me?

[@hilly900]

Lovely stuff, wonder if you can use it with a Sam Coupé...

[@MarkFixesStuff]

I believe it works because the Sam Coupe uses TZX archives as well

[@zxrenew5642]

That solder looks rubbish, nice video though.

[@MarkFixesStuff]

It's really awful. Watch the next video though.

[@pintokitkat]

You're right - that solder is awful.

[@thegreatjonzini]

You got a cold?

[@MarkFixesStuff]

Had a chest infection which is one of the reasons I’ve been quiet

[@thegreatjonzini]

@@MarkFixesStuff oh dear, great effort regardless 🥂all the best!

[@ASCIITerminal]

That's truly horrible solder! May I recommend Multicore? It's more expensive, but you won't need to add extra flux and it will actually flow instead of blobbing on the iron.

[@MarkFixesStuff]

In my latest video I've switched to Kester 44. I almost cried at the price, but it's amazing to use and will last a long time!

[@ASCIITerminal]

Ahhh OK! I haven't got quite that far yet. It's true though - Good solder makes the job so much easier!

[@markwrightrf]

24:13 "This thing needs a box - but not a cardboard box. This thing needs a box." The 80s hits that weren't keep on comin' ;-) Also, innuendo fans, listen out for references to a 'cheap stripper' and allusions to being 'screwed hard with a proper tool'. Mark, you will go to hell ;-)
