In our recent episodes, we successfully repaired this GameBoy Advance SP and upgraded it with pre-assembled mods. Now, we're giving the GBA SP an exciting upgrade:
Bluetooth functionality with an intelligent control. That's right! You can now connect your preferred speakers or headphones via Bluetooth and experience classic retro sounds in STEREO!
Did you know that GameBoys could do this? They can, after some modifications.

incredible modification, I am very glad that my comments helped you in the project, very good work, very clean I love

@CanWeFixThat 5 месяцев назад

Thank you, Pablo! It is not perfect, but maybe it will be in the future with the community's help. 💪🏻🙌🏻🌍

@PabloGil. 5 месяцев назад

@@CanWeFixThat the line that has come out in the back, is usually due to the fact that this type of semi-transparent shell usually use a less resistant plastic than others, for example funnyplaying uses a different transparent plastic that is something better. It's more normal to find this kind of damage by doing some extra pressure by accident on these kind of semi-transparent housings.

@CanWeFixThat 5 месяцев назад

Hi Pablo, thank you for this information. That is also an issue of the current mod state; without a transparent housing, you cannot see if the module is on or off. :-/

Once again, in an amazing way, I come across the Baader-Meinhof effect. A week ago, I started buying various parts for upgrading my gameboy advance sp from twenty years ago. And today I came up with the idea: is it possible to add Bluetooth there? And here you are, three days ago this video was released with detailed instructions on this topic. I will never stop wondering how the thoughts of completely random people in different parts of the world can synchronize) Thank you so much for the video, I have already placed an order on Aliexpress, I will return in mid-February for detailed instructions!

@PabloGil. 5 месяцев назад

I have been able to observe that AGND has it connected directly to GND. I was looking at your circuit diagram and it is possible that one of the possible reasons why that beep appeared in the sound was because it was not connected "correctly". The AGND of the Bluetooth module should be connected to pin 5 of the charging port, which uses a capacitor that eliminates part of the noise and prevents overloads. It is also possible that you can completely turn off the sound of the gba sp's internal speaker (I'm not 100% sure) but usually a short is created between pin 6 GND and pin 5 AGND charging port to turn off the speaker. Makho (a RU-vid content creator widely known in the gameboy mod community) has a good example of this in a video called "Building a Headphone Jackinto a Game Boy Advance SP" and within the comment posted by him there is another comment by a certain "homerghost" who quickly explains the mechanism. Don't worry about the issue of headphones exploding, since it is another modification, but it is true that the noise should be reduced and perhaps the speaker turned off by connecting those 2 cables to those 2 pins. In the event that you do not get sound from Bluetooth, this could be because you would have to use the left and right sound pins directly from the charging port. There is another video called "MOD sonido BLUETOOTH en GAMEBOY ADVANCE SP - EarPods, bocinas inalámbricas y mas" in which it leaves a link in the description of the video with a diagram a little different from yours in which it shows which pins are used. He uses, turning off the internal speaker when he turns on the Bluetooth module. In case you dare to do it, you can ask👍

@CanWeFixThat 5 месяцев назад

Hey Pablo! Thank you very much for your detailed post! The diagram I posted on the GitHub project page should be correct. During my attempts, I tested the AGND pad, and it was not the right spot for the Bluetooth AGND pin. But we should remember that I installed the Dehum-Kit in the previous modding video; this could smooth out much of the initial noise. After using the square GND pad, it worked like a charm!

@SebastianL.83 5 месяцев назад

So, here we go again :D Nice to see you :) In the next episode there will be a little roomtour?? :D only the workplace ;) When you pair headphones, is the internal speaker disabled? If not, this could be an upgrade!

@CanWeFixThat 5 месяцев назад

Hi Sebastian, now, can't hide anymore ^^ Doing a little workspace tour is a good idea, but not the next episode. 🤓 The internal speakers work in parallel; I just turned down the volume, so theoretically, you can blast your environment and your ears with headphones. 🤣

@jackipiegg 4 месяца назад

Cool implementation of attiny. Are the gpio pins all used up? I was thinking adding a 29Mhz crystal to make it switch between the stock (16Mhz) crystal for fast forward feature. Perhaps you could make an updated video!

@CanWeFixThat 4 месяца назад

Hi Jacki, first off: Thank you! 😉 Currently, the ATTiny85 is using its internal 8 MHz clock. You can check out my project page on GitHub to see which pins are connected and find out if there are any useful GPIOs left. Could you clarify what you mean by the "fast forward feature"?

@jackipiegg 4 месяца назад

@@CanWeFixThat Its a diy version of GBAaccellerator. Rather than paying for the outdated board, a simple switch with a higher clock crystal would be enough, and of course cheaper and accessible to everyone since crystal and switches are dirt cheap.

@CanWeFixThat 4 месяца назад

Ah, I see! Ok, that makes much more sense now! 😄 I think combining those things could be possible, but without a PCB design for the Bluetooth mod itself, adding anything else would be a nightmare to solder. However, I'll definitely keep it in mind!

@DanielVekony Месяц назад

Fantastic video! I’m aiming to achieve something similar, but with a twist: I want to bypass connecting the CON to any button and instead utilize the physical button on the emitter for pairing, possibly relocating the button to the side of the case. Do you think the pairing button on the Bluetooth emitter would be effective when pressed independently?

@CanWeFixThat Месяц назад

Hi Daniel! So you want to desolder the tiny button from the Bluetooth module and relocate it? This should work. ✌️🪛

@DanielVekony Месяц назад

@@CanWeFixThat exactly! I already have my IPS soldered to the Brightness button and the select button is not a good option for me. I will try to reallocate the little tiny button somewhere outside the case and use that physical button to pair. I was concerned if the CON needed to be connected to any point for the Bluetooth to be able to connect due to voltage perhaps.. would the physical button work independently? Thank you once again

@CanWeFixThat Месяц назад

Hi Daniel! Sorry for my late response. Yes, this should work with the physical button! Keep me posted about your progress-I'm curious to see how it works out!

@DanielVekony Месяц назад

@@CanWeFixThat hey Markus, thank you for your reply! I completed the mod and everything worked just fine. The only funny thing is that even when connected to the Bluetooth the speaker still works together, since the audio volume can be controlled independently, I just mute the SP when I connect the Bluetooth. I am not sure if there is any other way to do it 😂

@CanWeFixThat Месяц назад

That is completely normal! It is not a bug: it is a feature 🤣

@readifer 3 месяца назад

this is absolutely incredible. Would designing a custom pcb with the essential components of the attiny module and the bluetooth module be a proper solution with helping reduce the size/profile of the mod? i would almost imagine using a sturdy flex pcb like a lot of modern gameboy mods being very beneficial.

@CanWeFixThat 3 месяца назад

Thank you very much! There are also methods to create very thin flexible PCBs. But even these would slightly increase the thickness of the mod. I'm not sure if an IPS screen would be thinner overall to provide more space for the mod. Does anybody know?

@readifer 3 месяца назад

@@CanWeFixThat the ips screens are certainly a lot thinner then the vanilla screen for the sp. I personally just did a gba slab mod but the ips screen i used has a custom pcb with it to control color and brightness with conductive copper pads. However I know there are other ips screens that don't have those features and are very low profile.

@CanWeFixThat 3 месяца назад

@readifer That's brilliant, as it means the mod would fit even with a thin PCB. The only issue I foresee is if someone uses a non-transparent case, it might be hard to tell if the module is on or off.

@readifer 3 месяца назад

@@CanWeFixThat that's fair but I feel that's a minor detail that could be looked past when given the option to have proper Bluetooth pairing. I don't think it would cause much inconvenience beyond just having to press the brightness button a few times over until it connects to their desired device

@CanWeFixThat 3 месяца назад

@readifer Could you recommend an IPS screen kit? I might give it a try in the future. So far, the feedback on this mod has been unfortunately low. It took a lot of time to create this video and the project as a whole. But that's life, I guess!

@brandondavis6838 2 месяца назад

Awesome video! I had a quick question. When paired to a Bluetooth speaker, is the volume still controllable by the GBA SP, or only by the speaker. I’d love to replicate this and use AirPods, but mine do not have volume control.

@CanWeFixThat 2 месяца назад

Hi Brandon, thank you! 😉 The volume on the GBA still controls only the internal speaker volume, so unfortunately, you can't use the GBA to control the volume on the Bluetooth device in this setup. 🫤

@brandondavis6838 2 месяца назад

@@CanWeFixThat ah that’s too bad. Well that may give me an excuse to upgrade to the gen II Pros lol. Just thought of one more question. I’m planning on putting in an IPS screen on mine that has different brightness levels and color effects, all using the brightness button. Would that interfere with using the brightness button as the Bluetooth power and connection?

@CanWeFixThat 2 месяца назад

@brandondavis6838 I would say this should work (but can't tell for sure), but I suggest you first get the Bluetooth mod running and then install the IPS mod to see how they work together. Make sure the button press patterns are not the same for both mods, otherwise, you might trigger unintended actions from one or the other. Keep me posted! ;-)

I'm going to test if this is possible with regular gba as well. I've copied the video tutorial posted by gamboy custom, but there's a problem with the Bluetooth module not turning on like someone else said. So I'm going to use gba link port to power it up like you did in the video. The key is whether the link port of gba is the same as the link port of gba sp.

@CanWeFixThat 8 дней назад

Hi Yoake! Thank you very much for your feedback. I want to point out that I have NOT used the link port to power this project. I explained at the end of the video why this was not possible. You will also see in the GitHub repo that I used another test point for that. Long story short: the voltage differs when you play a GBA or GB Classic game, due to specifications. I hope that helps! ;)

@@CanWeFixThat Thank you, but the regular gba doesn't seem to have a 5v pin. It's sad

@YoakeZet 7 дней назад

@@CanWeFixThat I ordered a multimeter machine for testing. But I saw retrosix wiki and it says that 5v is formed on the second pin on the lower left side of the power regulator of the gba. But I don't know if I can solder the 5v terminal of the Bluetooth module to the power regulator. It's a power regulator, so I don't know what the problem will be with the gba if I draw the power of the bt module from there. I'm a non-major in this field, so I don't know the details, but it's just my guess.
