I first found your videos a few years back when I was procrastinating from my final exams. Now, this bloody pandemic and your fantastic videos have given me the push I needed to get into hobbyist electronics for myself. Thank you for your fantastic content Darren, and I shall definitely grab one of your kits when I can figure out how to use em. Cheers and keep up the fantastic work.

[@GlobalGarageAus]

Patrick Hosseini Thanks for that. I really should make more videos but I’m a bit low on motivation. Also have a son now so spare time is minimal. I have been playing around with the OG XBox but there’s already so many top videos

[@Charlie-Cat.]

I'm always in the mood to be enlighten by your educational uploads Global. That's why its an honor seeing a talent man like yourself performing them. 8^) Well done as always bro. Anthony..

[@GlobalGarageAus]

Thanks Charlie

[@Charlie-Cat.]

You're welcome Global. Always a pleasure. Anthony..

liking the 3d printed DC port very clever idea to stop people drilling holes in Thier consoles , another awesome video

[@GlobalGarageAus]

MrKrimstah Thanks. Yep I try not to damage any of my cases anymore, so the rear 3D printed panel was the obvious solution.

[@anthonygiangiulio8853]

This is huge for my RV. THANK YOU!

[@james276]

Very professional job mate! I really like the 3d printed parts, Such a great touch.

[@GlobalGarageAus]

Thanks!

[@mr.dmr.d9348]

Thanks again for a great video. You have helped me out a lot with my projects now. I've modded quite a few Famicoms to AV now using your Guide. so I was glad it was you when I wanted to do this Mod , i did battery with a green a LED. HAVE YOU DONE A VIDEO for a N64 rgb amp mod...? Thanks, Paul

[@RetroTech100]

Great channel and very straight forward mod. I think maybe even I could do it lol.

[@GlobalGarageAus]

Have a go! It's quite an easy job.

[@josphok4142]

great video mate ,plz keep up

[@GlobalGarageAus]

Thanks. I have plenty more videos in the making/planning but they take a lot of time so it's just a matter of doing them whenever I can. This is just a hobby and not full time like other youtubers.

[@TheSillyBatdoctor]

You can disable the charging cicruit by using a diode and solder that to the resistor

[@CHABBO]

Fantastic video! Oh and please tell me the what and where with those awesome wire strippers! I need them! :)

[@elamriti]

i was waiting for this thanks :) i contacted you via facebook about the status thanks for the video

[@GlobalGarageAus]

Hey, yep I got your message thanks. I was waiting on a few parts to arrive before doing the mod. Parts from China can take 3 weeks.

[@elamriti]

iam posting your video about this on difrent groups i have on face book and twitter if its oke with you :)

[@GlobalGarageAus]

scroeffie Of course that's ok. Thanks

[@ChrisGhysel]

I used the power button to bridge 15 and 16 on the pico. Power off, connection open. Power on, connection closed.

[@GlobalGarageAus]

Chris Ghysel Yep that's a good idea and probably going to be in the instructions with the final kit I release. Thanks for the comment.

[@Megareos]

What is the name of the 6-pin connector you bought to connect the cable to the console?

[@cleandave]

Really like the 3D printed part plus the ability to run in my car on 12 volt system. What has me really confused is trying to figure out why your first step was bridging the on-off switch only to add a cutout later... you could have just soldered the wires straight onto the boards built in on-off switch you bridged to begin with. Not only would it turn the console on and off, but it would not have hot 12 volts going through the small switch. It would be a signal wire super low power like the factory wanted. Plus it's basically just extra work and more connections to eventually have problems. Effective use of add on switch would only be better if used to cut out the 110 before the first inverter. Not at all trying to bash or hate, just perspective. I learned and will probably use this type of setup for hooking up my Dreamcast in the car. I do think it is overall a great mod! Cheers

[@GlobalGarageAus]

You're absolutley correct sir! I regret filming it the way I did. I did it that way for simplicity so beginners can follow along, but the way you mentioned is the way I personally do it so I think I'll remake the video and post it again. I point the instructions to this video, so I'll send all the buyers of my kit to the new one.

[@LFiers]

@@GlobalGarageAus Hi, where can I ask the new updated video? Thanks

[@zulnoth]

Always love your videos Darren. Not selling the 3d printed parts for the gdemu?

[@zulnoth]

nice, thanks mate!

[@VIRUZ5K1]

Do u guys ship to the UK these kits an if so what the p&p . I looked on site but couldn't see

[@frankynakamoto2308]

They should make a network adapter for Dreamcast with an SD to play games from it, would be great idea, also they could replace the network port with a new one, and they should make a Sega Saturn 1GB ram cartridge or something like that with an SD slot in, so it can run games from it, will be awesome.

[@Spartan117TCF]

Nice mod video. Where do you get the plastic header connectors and clips from ?

[@GlobalGarageAus]

They are just headers, so you can pick them up at most electronic stores or online

[@markantony7413]

If the 12v is getting used, (not sure if it is) why not use the original psu? Does it produce too much current or something?

[@emmettturner9452]

Couldn't you wire the power switch to the Power Good/PSU On pins on the ATX connector?

[@GlobalGarageAus]

Yes you can. That's an alternative way to do it.

[@CaseTheCorvetteMan]

Why are you not installing an internal 100-230v step down to 12v so you can just as easily reuse the same figure 8 230v power cord? Id expect there is enough room for that to fit without an issue, and theyre about $6 delivered to Australia.

[@cyo_corner]

hey mate have you thought of using a pico inside a PS1 ?

[@Auyx]

What was the model of the little watch battery holder? Gonna replace my DC's case soon so I might as well do it at the same time.

[@GlobalGarageAus]

Just grab any off eBay. Search for "Vertical coin cell battery holder"

[@57Rye]

Is there any way that this mod could be changed or modified so that the output of the pico psu could just use a standard figure 8 power connector?

[@GlobalGarageAus]

Not really, the PICO needs 12V DC and the figure 8 cable from the wall is anywhere from 100-240V AC. It's this conversion that is what the external 12V 5A power supply is for. You could hide it inside the console if there was room I guess, but generally the decent ones at 5A are quite large.

[@KRAFTWERK2K6]

How well does this work in combination with the GDEMU SD-Card board? Does the new PSU hardware withstand the higher stress?

[@GlobalGarageAus]

It works perfectly. The GDEMU actually puts less stress on the power supply

[@KRAFTWERK2K6]

@@GlobalGarageAus Awesome! Good to know :) Thank you!

[@lefferaggmunk4833]

Works but i got much interference on the image?

[@Wallcrawler]

Can you create a tutorial on how to do this with a US Dreamcast? My GDEMU keeps flickering.

[@GlobalGarageAus]

Wallcrawler The Black Sega Sports Dreamcast in the video is a USA one. The conversion works on any model.

[@spideliciousx9822]

I see a lot of your tools there look like Jaycar tools.... (red wire strippers, alligator clip pcb holder etc) 😉

[@GlobalGarageAus]

Supa Troopa Yep they are! I’ve upgraded since these videos but you only need basic tools.

[@spideliciousx9822]

Global Garage 👍 yeah nice. I’ve got a few of those, which is why I recognised them 😂

[@ekstrememofo8035]

Great job. Just picked up my first Dreamcast, which is Japanese. Any idea what the kit is going to go for?

[@GlobalGarageAus]

The Japanese Dreamcasts are great, especially an early revision. The parts for the kit are quite expensive, especially the PICO power supply. I'm still getting pricing options from various suppliers. I want the kit to include everything so it's easy for the installer. Under $50 AUD

[@TrevorStokes1]

What's the best way to be notified if the kits become available?

[@bjornjadeholm7451]

I did this mod but the dreamcast led Only blinks then nothing. Any i dess?

[@nonosto5750]

Hello 12V is it necessary for DC with GDEMU? How to decrease temperature from PSU?

[@GlobalGarageAus]

It's best to replace the power supply completely.

[@gregjarvis1232]

even though my dreamcast battery is working I would be intreasted in buying the 3d printed battery holder very simple to replace battery

[@GlobalGarageAus]

Greg Jarvis The battery holder isn't 3D printed, that was the power supply output part I made. FYI here's the rechargeable Dreamcast battery kit for direct solder in www.retrosales.com.au/products/parts-modding-dreamcast-clock-battery-replacement

[@Lunablack14]

Hi, I was just wondering if you accept commissions for fixing handheld/electronics?

[@GlobalGarageAus]

No sorry. Handhelds are not my thing

[@Lunablack14]

Global Garage It's actually a D-Tector from Digimon but I wasn't sure how else to refer to it-not sure of that makes a difference but thank you for replying and letting me know.

[@Protofall]

I know you say use a 5A brick since 3A is too close, but I happen to have a 12V 3A laying around and the Dreamcast PicoPSU kit you linked comes with a 12V 3A anyways. How bad could a 3A be? Would it just power off/restart or possibly damage a component? I'd prefer to just use a 3A since I plan to do two mods and that will save me abit of money.

[@GlobalGarageAus]

Protofall Yes that’s my kit. They all ship with 3A power supplies now.

[@Protofall]

@@GlobalGarageAus How come it comes with a 3A instead of a 5A since you mentioned in both this and the Saturn video that you should try to get a 5A if possible? Btw I like your videos on installing this mod, it makes me a lot more confident to do it myself. Thanks :)

[@Protofall]

I just saw Xaranar's comment below which seems to explain why you chose the 3A option. Cool :)

[@xDakem]

Man,did the LIR 2032 work the same on the battery for the time?

[@GlobalGarageAus]

xDakem I don’t think i understand your question? The LIR is 3.6v so it’s not the correct one to use. You should only use a ML2032

[@arcademan8899]

i have a dreamcast VA1 model PAL and i have a GDEMU is it a good idea to get this PicoPsu PICO ATX Kit ???

[@GlobalGarageAus]

Your original PSU will be getting hot on the 12v line, so it's a good idea to either modify the stock one or just put in my kit.

[@arcademan8899]

just ordered from your website :)..... btw will you be getting Clock Battery Replacement back in stock any time soon ????

[@GlobalGarageAus]

OK great I can see the order. Yes the Dreamcast batteries are on their way from the supplier now. Contact me at [e-mail] and we can discuss what to do. Maybe hold the order until the batteries are in?

[@arcademan8899]

send my order i have made and let me know once u get the battery kit in

[@groomery1]

Does it need to be 12V i have a power supply from a laptop but that is 19V does it do? How many AMP is recuired?

[@GlobalGarageAus]

It should be 12V and 5A DC

[@AndehX]

has to be 12v. You can't feed a PicoPSU 19v, you'd kill it.

[@GlobalGarageAus]

oldgraphics that’s about right. 3A is not quite enough, so I’d recommended 5A

[@AndehX]

3A is more than enough for any system. GDEmu does not need anywhere near that much power. Infact GDEmu pulls power from the 5v rail, which never pulls more than 1A max. You don't even need the 12v pin connected when using GDEmu

[@Ashkimbo]

What kind of pin header did you use for this?

[@GlobalGarageAus]

One that fits! :) I think it's 3.96mm

[@SonicBoone56]

Is the kit available in America as well?

[@GlobalGarageAus]

Socky Noob Shipping is worldwide from retrosales.com.au

[@xmodsgaming]

I would of joined the ground and green to the power switch

[@arcademan8899]

how is mod compared to the DreamPSU ???

[@RallyDon82]

dream psu is essentially the same, only its a plug n play easy install.

[@SonicBoone56]

Couldn't you just use a LIR2032 battery instead?

[@GlobalGarageAus]

Socky Noob Not really as the LIR2032 is 3.6v

[@donsizemore8746]

Do you ship to the U.S.?

[@GlobalGarageAus]

Don Sizemore Yes I ship worldwide on retrosales.com.au

[@bjornjadeholm7451]

How many w is the pico psu on?

[@GlobalGarageAus]

The Pico itself is 160W which is overkill but that's all they make. The external 12V power supply I use is 5 Amps so that makes 60W which is also a lot. You could get away with a 3A external supply.

[@bjornjadeholm7451]

Global Garage thank you for your answer. I did this psu mod but when i start the dreamcast the light Only blinks then it shuts down. But ur i took out the gdrom it runs about 10 sekunds then shuts down. Any ide about whats wrong? I have tried it on two diffrent dreamcast but the same result.

[@GlobalGarageAus]

Björn Jädeholm How much current does your external power supply have?

[@bjornjadeholm7451]

Global Garage it has 12v 5a

[@Auyx]

Also if you have a GDEmu I can highly recommend the Noctua 3d printed fan mod. Stops it sounding like its a helicopter when you're gaming. I bought mine from this guy on ebay www.ebay.co.uk/itm/Dreamcast-silent-fan-mod-kit-including-Noctua-fan-/272648327162?hash=item3f7b1b4ffa:g:MJIAAOSwN6JY9tC7

[@GlobalGarageAus]

Thanks Ill look into that!
