Hi everyone I've been working on a design for a small form factor, high-reliability, all-SSD storage enclosure, and I would love to get your expert feedback on its feasibility and overall design choices. The goal is to create a compact and affordable JBOF (Just a Bunch of Flash) for prosumers...

Thanks for your 2 cents! I do want to emphasize that my M.2 card is, in my view, 100% an absurd and obsolete product (being PCIe 3.0). This is especially true because, in my region, everyone can now buy affordable PCIe 4.0 M.2. That's why I'm still baffled someone would copy it. You absolutely...

Hey everyone, I'm hoping to get some advice from the community because I feel like I've hit a wall and could use some fresh perspective. I love working on hardware projects, but I'm struggling to land on a viable idea that I can see through to completion. Here's a rundown of what I've been...

Yep, the plan is to RMA it this week. I got it from a third-party seller, so it only has a 3-year warranty, but that was the trade-off for the cheaper price. Since it's only 2 years old, it's still covered.

Hi everyone, Two nights ago, my PC suddenly crashed with a Blue Screen of Death (BSOD). Here's what happened afterward: On the first reboot, the system loaded but then completely froze. I restarted it again, but this time it got stuck on the motherboard's boot logo screen and was...

I usually have JIEPEI in Shenzhen make them, which takes around 3-6 days due to the complexity of 4-layer PCB

Hey everyone. GPU servers are prohibitively expensive and way beyond my budget. However, I'm eager to achieve the local deployment of the Llama LLM. So, I had to come up with an alternative solution. I've designed a GPU expansion board with PCIe 4.0. The distance between the 2 slots is a...

I'm planning to use Ubuntu Desktop and Nextcloud for the system and software. For hardware, I'll source PSUs from Hunkey or Huawei and design custom fans using CFD simulations. I have a logistics partnership to keep shipping costs low, and a stockpile of spare parts for efficient warranty...

My words might be a bit off 'cause English ain't my mother tongue. I'm thinking of putting in an 8 port M.2 expansion board and a 4 port 2.5gbe or 2 port 10gbe NIC, and then selling it as a NAS.

I used Fusion to design this NAS, with a size of 390x450x89mm. It can fit a MATX motherboard, and it uses a CRPS PSU (12VO). There's a reinforcement rib in the middle, and on the other side, I have the freedom to design the PCB to achieve the expandability I want. For example, I could add 12...

Try measuring VBUS and GND with a multimeter after disconnecting power. If no shorts, wiggle the plug and recheck. If still no shorts, it's safe. One missing VBUS pin may cause power issues, but it should still work. This is just a temporary fix. You're better off returning the motherboard to...

Memory and CPU are powered by the 12V main power supply through voltage reduction chips. Even if the hardware is incompatible, when you press the power button, the motherboard's chipset will attempt to execute the boot process through the firmware, and there should not be a situation where there...

The fan is defective, and the problem is a damaged startup capacitor inside. I suggest returning it to the seller. The reason is that the fan should work as long as it's connected to 12V and GND, regardless of whether there's a PWM signal or not.

You're seeing the motherboard's 5V STBY power. Remember, the system fan needs 12V to run. Without a CPU, the motherboard's protection circuit might block 12V power

Hello everyone! I'm exploring the possibility of creating an M.2 SSD expansion card based on the AVAGO PEX8748 chip. The card would utilize a PCIe x16 slot and take advantage of PCIe 3.0 speeds. Here's the idea: I want to design a card that can accommodate up to 8 M.2 SSDs, effectively...
