NeMesiS Posted June 16, 2023 Report Share Posted June 16, 2023 I've been designing and selling xbox mods for the better part of 3 years now. I was keeping things rather low key so I could avoid registering as a business. But it's time to decide either to fade away or go all in coming financial year... You can check out my previous works over at EmuXtras: https://www.emuxtras.net/forum/viewtopic.php?f=187&t=6786&sid=092ae8a1ea7b8d5f5ae4b33f3ea1de69 I've been busting my **s over the last 3 months working on projects. Feeling really burnt out I could use some motivation from the community. Below are my 3 main projects for Version 3.0... **Will post images shortly (1) Dual 80mm Fan Caddy Convertion (Beta) - including redesign of the HDD Caddy, etc. - would like to do a PWM fan controller based on CPU and MB temps via I2C. (2) XeniumICE Redesign (Beta) -inspired by the XeniumGOLD 24k modchip. -extra connectors for more specific tasks. -edge connector pads for fast programming. (3) XeniumHD+ Standalone HDMI Mod (WIP) - can't say too much just yet as it's still a work in progress but hope to have a working prototype within the next month or two. I'm sure there will be many questions for a variety of reasons... PS. I'm looking for testers within Australia preferably people who contribute alot to the xbox community.

Bowlsnapper Posted June 16, 2023 Report Share Posted June 16, 2023 @NeMesiS I would LOVE to test ANY of this hardware. This is what I've been waiting for, if it is what I think it is. You have an HDMI encoder in progress. A HUGE step forward for the community. I want you to finish and to KEEP GOING. Why stop at HDMI? Take it even further. I would love to see a team develop that can rival MakeMHZ. I'm sure I'm getting ahead of myself a bit, but with the sufficient motivation and collective knowhow, I'm sure we can come up with the Stellar that SHOULD have been engineered. NEVER stop, man. I'll follow this every day. I'm a fan. I just wish I could contribute somehow... @SS_Dave @KaosEngineer@Dtomcat18 @OGXbox Admin 2 Quote Link to comment Share on other sites More sharing options...

NeMesiS Posted June 16, 2023 Author Report Share Posted June 16, 2023 (edited) Glad you like it... Are you in Australia? I read a thread you posted in, which prompted me to share what I've been working on. I have a few more projects in mind but time will tell. The IDE cable is just for fitment purposes... I had to change the design of the modchip at one point as it was too close to the IDE connector/cable. My greatest limit is that I am but a one man show and there's only so much time in one day. Finding good help has been next to impossible or overly expensive. Many of my projects are based on works by Ryzee119 Ryzee119 (Ryzee119) / Repositories · GitHub Sometimes even the smallest contribution can make a large difference. So don't shy away from trying stuff. For example, if you were to tinker towards a PWM fan controller there are many similar projects on github already. GitHub - heresiarch/ATtinyFanControl: Drive an 4 pin PWM Fan using an ATtiny45 or ATTiny85 which was harder than I thought GitHub - crycode-de/attiny-i2c-fan-control: Control a PWM fan over the I²C bus. There are boards ready to go and all they needs is the cpu/mb i2c address Adafruit EMC2101 I2C PC Fan Controller and Temperature Sensor [STEMMA QT / Qwiic] : ID 4808 : $5.50 : Adafruit Industries, Unique & fun DIY electronics and kits You can get the CPU and MB i2c address from Ryzee119 SPI2PAR project spi2par2019/xboxsmbus.h at master · Ryzee119/spi2par2019 · GitHub Lines 33 & 34... #define SMC_CPUTEMP 0x09 //CPU temperature (°C) //Read from ADM1032 for better update rate #define SMC_BOARDTEMP 0x0A //board temperature (°C) //Read from ADM1032 for better update rate I don't think we need super fast update otherwise refer to lines 42 & 43: #define ADM1032_MB 0x00 //°C #define ADM1032_CPU 0x01 //°C I wanted to do something where we would get an average of the two temps (CPU and MB). Those GitHub PWM fan links don't have many lines of code so I don't see why ChatGPT couldn't be used. I'm sure there would be more to it but that's where I would start.

sixspeed Posted June 16, 2023 Report Share Posted June 16, 2023 Awesome work!! Would really like to see you continue on this - the HDMI mod itself will be a huge, put my down for a few of those when they’re done. Quote Link to comment Share on other sites More sharing options...
ShinGoutetsu Posted June 17, 2023 Report Share Posted June 17, 2023 (edited) I have one of your xenium chips in my personal xbox and it's great. I'm not in Oz but also more than happy to test anything for you. Probably not feasible though as I'm in the UK. I've followed your work on emuXtras for a long time (I'm ShinGoutetsu on there too), you do great work!

Bowlsnapper Posted June 17, 2023 Report Share Posted June 17, 2023 First of all, you redesigned the modchip. Nice work. I noticed that and didn't recognize the chip for a few seconds. Lol. I wish I understood the fan controller, but the truth is I don't have experience. But the caddies look PERFECT and have a nice fit. Beautiful work, dude I can't wait to try this out!

NeMesiS Posted June 18, 2023 Author Report Share Posted June 18, 2023 (edited) Glad you guys like it so far... Designing that fan caddy was a nightmare, it's something I've been working on for a few years now. Managed to do all HDD caddy among other things when I first got a 3D printer. And all of that was to support the dual fan caddy idea. Tolerances were extremely tight and much of it had to be spot-on for it to even fit. I broke up the design into separate parts to better suit 3D printing. This helped alot in making the design look interesting from all angles. But I'm a little stuck on cable management, I tried to allow for it with cutouts. I like the Noctua 80mm Chromax fans as they have a really short cable coming off them. Making a custom cable to suit wouldn't be too difficult. Alternatively, could do something similar using a PCB with molex and fan connectors And since we have a PCB why not implement a PWM fan controller. I have not had the chance to see what the airflow will be like (with and without top shielding) Even though I'm confident, I've somewhat been hesitant to test it after putting all this time into it. I need to pull out an old shell that's in bad condition, drill a hole in the back so I can adjust fan speed while the lid is on. Perhaps use some incense sticks to help visualize airflow. This is probably the first thing I could use testers for, just need to print it. The PCB designs will take a bit longer before I'm ready for testers.

dtomcat Posted June 18, 2023 Report Share Posted June 18, 2023 (edited) you could also incorporate a couple slits in the print to allow cable ties? Just an idea for cable management before the PCBs are ready Edited June 18, 2023 by Dtomcat18 Quote Link to comment Share on other sites More sharing options...
dtomcat Posted June 18, 2023 Report Share Posted June 18, 2023 Also I have a couple 3D printers if you need someone to test. Have a few Xbox’s as well Quote Link to comment Share on other sites More sharing options...
NeMesiS Posted June 18, 2023 Author Report Share Posted June 18, 2023 (edited) Yea I thought about that or even some 3d clamps or brackets that can be screwed down. But I would like to see how a handful of testers will go about it. It'll be trickey as there's not alot of room and we still need power for the HDD on the opposite side. There's also an unused fan header that used to be for the GPU fan for v1.0 mobos. (except v1.6) It isn't speed controlled but could provide power for the fans or a fan controller.

NeMesiS Posted June 18, 2023 Author Report Share Posted June 18, 2023 Again, I took inspiration for the modchip redesign from the XeniumGOLD. But there are a few differences, most obvious is the edge connector pads. I've been wanting to do something like this since I first saw the programmer by kooscode GitHub - kooscode/xenium-programmer: OpenXenium CPLD and FLASH programmer I did a 3D mock-up of a PCB based on this project with programming multiple modchips in mind. 1 Quote Link to comment Share on other sites More sharing options...

I have all models available and can 3d print on my side as well. Keep me in mind if you need any kinda testing needed. Quote Link to comment Share on other sites More sharing options...
NeMesiS Posted June 18, 2023 Author Report Share Posted June 18, 2023 I'm very protective of my designs especially after all the work that's goes into them. So I typically avoid sharing them at all costs. Printing them myself is not a problem. I managed to sell alot of my consoles over the past few months. Which gave me the opportunity to upgrade a few things including my printing setup. I had 2x Cr-10s Pro V2's but turned out to be too large for what I needed, plus they were aging. So I upgraded to 3x Ender 3 S1 Pro's along with a Sonic Pad. Turned out to be quite a step up in quality and speed. 3 Quote Link to comment Share on other sites More sharing options...

dtomcat Posted June 18, 2023 Report Share Posted June 18, 2023 Your chips could be a different story since they technically have to be open sourced (xenium based chips) Quote Link to comment Share on other sites More sharing options...
