Hi! I'm Ivan (@merocle), nice to see you here! This account for my different DIY projects. no AD, just DIY

I don't think I told you much about Compute Blade

I don't think I told you much about Compute Blade version 0.7
Here it is, with the kitty from the Matrix 🙂
Here's what's new in version 0.7:
- Everything that is in 0.6
- Added a switch to the Dev version. You can turn EEPROM write protection, wi-fi, BT on or off with a switch
- LEDs on the front edge of the PCB
- Components moved a bit
- A switch on the front edge to be pressed with the blade latch. Connected to the GPIO. Can be flexibly programmed with scripts.
⠀
Lots of changes, but not as much as will be in 0.9 Release Candidate 1. Version 0.8 was skipped because too many changes were made in 0.9 RC1.
⠀
On image 4, there are all generations of Blade at the moment (I have a few soldered of each, and a couple are in production)
- v0.7
- v0.6
- v0.5 (micro-HDMI was a wrong choice)
- v0.2 (blue-green deployment example 🙂 )
- v0.1 (developed in a browser-based editor, soldering without a microscope)
⠀
On image 5 Fan Unit v0.1 (based on RP2040). I'll tell more about it in the next iteration

A cluster of 4 new Raspberry Pi zero 2W.
There's 5GB of RAM:
512 per node and 3GB on the Raspberry Pi 4 (re-soldered earlier, the 8GB chip went on the CM4)
based on ClusterHAT

MinCab v1 Minimal (useful) carrier board for Raspb

Unreleased Raspberry Pi Server Mark IV (Uptime Platform)
48 Raspberry Pi 4 with SATA SSD each and PoE HAT in 2 rack units. Ethernet with PoE brought out to the front panel from each Raspberry.
Each node with its own small cooler (with air intake) on the PoE HAT. There is room for an SSD, between the Raspberry and the bottom, but their installation has not yet been finalized.
I stopped this design around February and switched completely to Compute Blade. Because with the same density they will be much easier to maintain and reliable.

UpBerry v0.3: Summary
⠀
1. Aluminium case is perfect. I didn't expect it to be that nice (overall feeling and temperatures). Under the full load during the whole hour (FULL LOAD!) the CPU temperature was only 60℃, and the case was 50℃. In normal conditions, the CPU is about 45℃.
2. Assembling was a bit complicated. Had to cut off the parts from the USB-C port, because I mixed up the PCB footprint a bit. The case hole was also designed for another port. However, everything is fine and the prototype is fully functional.
3. Bootloader update button works great, you hold it during connection to another PC and then release. This allows you to flash the OS or change the config file.
4. There are no problems with the Wi-Fi signal. It does not interfere with the case at all.
5. You can use a monitor with a USB-C hub, for example, and connect the mouse and keyboard to the monitor. USB power delivery works as well.
6. The size is 58*58*13mm (2,28x2,28x0,51'') Characteristics depend on Raspberry Pi CM4 you use:
- quad-core Cortex-A72 (ARM v8) 64-bit SoC up to @ 2.2GHz (OC)
- H.265 (HEVC) (up to 4Kp60 decode), H.264 (up to 1080p60 decode, 1080p30 encode)
- up to 8GB LPDDR4-3200 SDRAM
- up to 32GB eMMC Flash memory
- 2.4 GHz, 5.0 GHz IEEE 802.11 b/g/n/ac wireless;
- Bluetooth 5.0, BLE;
- HDMI port up to 4k60
- Power 5V 2A (usual USB port on monitor or TV)
- Bootloader button, you can flash, update and configure the device from another PC just with a usual USB-C cable
- USB port can be used to connect the mouse and keyboard with the hub
