Retro Gaming Handheld Without a PCB

[@element14presents]

Hey everyone, hope you like the new episode and welcome Dave to element14 presents! We're actually always looking for people to come along and present as part of the show and join us as a video content producer. If you want the schematics, code and parts used then you can find them here : bit.ly/2Ef8T2N and here's a link to Karen's resistor's episode: bit.ly/2T3yYMB

[@tahsinrumana473]

Thanks! A great project. Is it possible to use a joystick instead of buttons?

[@nardjanssens6049]

Nice build. You could partially cast the circuit in clear resin, so the buttons and AT-socket stick out. This will leave you seeing the nice build, but makes it more robust!

[@Davedarko]

Seems to be the popular opinion here :) I will give it some thoughts and probably post something on my channel and over on the e14 community

[@BrainSlugs83]

You can still program the ATTINY using high voltage programming if you use the reset pin for I/O. Shouldn't be complicated to augment your ASP to do it.

[@Davedarko]

That is correct. I do have a "high voltage" programmer (modded arduino ISP) for that as well, but this video is also aimed at people who might not have one and this was just more convenient, so I said "not easily" ;) Daniele Champagne was commenting here that he actually doesn't even set the fuse to use the reset pin as an input.

[@jparky1972]

I love the skeleton design. More display item than "usable" form. But from an artistic point. It's quite beautiful.

[@Davedarko]

Definitely a looker :) I'm currently in the process of embedding it in resin. I will post a video on my channel soon and add a little "community update" to my next video. Thank you for your feedback!

Very nice and simple design. Not every home lab has a PCB etching or milling tools, so this is an option also. Would like to see more content like this!

[@Davedarko]

Thanks for the feedback, Dmitry! Next one will be a bit more exotic, but I will try to keep it in mind!

[@WistrelChianti]

Thanks that was a really fun and interesting video. Another way to reduce inputs is to exploit the fact that a D pad never goes up and down or left and right at the same time, so hook these input combos to be switched together on the A and B buttons respectively. You need diodes so that up isn't triggering down (and A) after though (for example). This gets you 6 buttons on 4 inputs. In theory, you could hook a 7th (C) button up to all 4 inputs, but that would require the A and B buttons to be on a rocker, else you couldn't differentiate between the A and B button being pressed simultaneously or the C button being pressed.

[@maker_karen1785]

[@Davedarko]

[@ElectroLIB]

👍👍👍👍👍 What a wonderful surprise to see my little games run on your beautiful project! Really very pretty! Good work. Simple Accuracy: in my game codes, I use the pin reset as analog input, but it is quite possible to reprogram the attiny85. I just used the tolerance gap before detecting the reset! Nothing to change in the configuration of the attiny85. 👍👍👍👍👍

​@@Davedarko Too kind, but Daniel C (kzbin.info/door/PnC4IokfrPM9MF9BiGmuvQ ) should really take the credit for Tiny Joypad. His schematic, game code, and he even consulted on the PCB design.

I personally love this style of circuit, it gives it character and depth.

I'm going to encase it in resin / epoxy soon, first tests look very promising. Hope it helps keeping the character and make it more robust :)

[@HobkinBoi]

@@Davedarkoah, that's cool. A suggestion, you should maybe make it rechargable. A small Lipo cell would probably last longer than a coin cell, and you wouldn't need to worry about replacing it.

[@Davedarko]

@@HobkinBoi I thought about that, but than I would want to also add a wireless charger etc. and that thing will get more and more complicated 🤔anyways, thanks for the feedback!

[@HobkinBoi]

@@Davedarko Fair enough, lol. It would probably require a total redesign too, if I were to guess. If you do make another one, it could be your third version. Though if you do ever go about encasing it in resin with a lipo cell, make sure you give it room to expand and to vent (in case of it puffing up).

[@Davedarko]

@@OnezOgirdor always good to have a project to focus on, when you want to learn something! I'm not sure, but I think there is no ADC pin on the Raspberry PI to do that. There are a lot of tutorials on adafruit (look for game girrrl etc.) to make buttons work on a RPi. I personally used an atmega32u4 board on my handheld for that and connected it via usb.

@@wabsol since everyone seemed to like the simplicity of this one, I thought about doing something that doesn't involve coding at all.

@@Davedarko hmm, seems like there's a line roughly down the middle where there is nothing but metal -- no resistors or other components. that was what i meant. that would put the battery roughly behind the screen, for example.

It is possible to upload the game codes to an SD card e then you read from attiny e load the game ? The code will be very complex, but you know if anyone tried this ?

I believe that Djamal uk is doing a project on this topic which has been named TinyConsole_V2 ;)

[@Davedarko]

The only thing close that comes to my mind is Atmega32u4 based and that's a modded Arduboy. You would need a special bootloader that reads games off of an SD card into its own program space and show it on the screen for you to select. That'll take some of your program space away already and so space for games is even less on an 8k chip. There has been someone on hackaday also adapting the console by Daniel Champagne and putting the attiny85 on an microSD card shaped PCB: hackaday.io/project/164736-multi-game-console

this question does not correlate to the vid post but i am curious. why do all wires differentiate by color? does every color in every wire corresponds by voltage capacity? like black as negative or ground? what if i choose red color as a ground does it have a cons? PLEASE ANSWER someone who is knowledgeable to electrical engineering

[@Davedarko]

First: never trust the wiring of a project- I've had several cables use the right color scheme, but switch ground and VCC. Normally people try to use black for ground and red for VCC though. It's always good to have different colors for different voltages /signals. But it's also good to always check your assumptions.

Hi Brian! You will need a USB ISP programmer (or any arduino) for programming the attiny. There is no bootloader (what you probably meant with OS) needed, as you will program the chip directly. This is an older video kzbin.info/www/bejne/aWHVgaduZZehZ80, but also try googling for "programming attiny85 with arduino". I will see that I can make a video on how I did it as well.

[@Lardzor]

Why not design a single sided circuit board, and use the schematic to laser-cut a piece of steel. The fiberglass is there mainly for rigidity. The steel should provide the necessary rigidity. Maybe get creative with the ground rail for additional support. You should be able to outsource the laser-cutting to some Chinese company.

[@Davedarko]

Laser cutting steel sounds like something that I consider not that easy for everyone to get access too. Not that every video on this channel has that on mind, but in this case it was more about that skeleton style of soldering, making it easy to copy, if you've always kept your LED legs, like Ben Heck told us :) Thank you for your input, much appreciated - have you ever outsource a steel laser cut to China?

That would be tricky. I've seen the Attiny85 getting powered over data lines because of the diodes on the IO. There are other concepts for Daniel Cs games out there, where you can swap tiny PCBs. I like the way you think though, thanks for the feedback! :) hackaday.io/project/159741-tiny-joypad hackaday.io/project/164736-multi-game-console-attiny85-atmega328-and-more

Such a cool minimal design, so much steam/cyber punky coppery potential! Nice One Dave! Great to see you on the E14 show!

Hi all, I was wonder if anyone knows of a little board that I could hook up a small LCD and plug in an micro SD card and run vidoes. I'm looking to make a very small video player kinda like those smart pictures frames things.

[@Davedarko]

Hi duby - that all depends on the size and coding effort you're aiming for. Video decoding isn't trivial, so you'd need a beefier board than a standard atmega328 based arduino. It might be easier to go with a Raspberry PI, but that means you should feel comfortable with working in Linux. I suggest to look around for similar projects - try to combine raspberry or arduino with video from SD in your searches, as those have the bigger community to get started with a project like that.

[@duby149]

@@Davedarko not going to lie I only understood half of that LoL, but I have no programming skills what's so ever. I thought of using a Raspberry Pi but that seems like such over kill for just to play back a video on repeat, i have seen what I'm looking for a few times in stores on displays for make up like there will just be a little screen with a board and an micro SD card playing a video or a gift not sure in a loop.

[@a531016]

I am definitely going to make on of these, great project!

[@Davedarko]

good luck! :)

[@erikvincent5846]

Too bad the code doesn't even turn on the I2C display.

[@dutchmakernl]

Cool video. Idea: create a simple cardridge system to easily swap out ATTiny chips.

[@Davedarko]

actually there's already a project that does that and where I found the games for this in the first place :) hackaday.io/project/159741-tiny-joypad

[@xXDeltaXxwhotookit]

That is a cool project

what about epoxy?

[@Davedarko]

It has been mentioned here - seems like I'm going to try that and put a video on my personal channel -> but also will share this on the E14 community and in a community feedback section in one of my next vids (hopefully). Thank you for the feedback!
