So someone in FLOSS #DeltaChat group said #ARM #SBCs are terrible at computation power. And that a #miniPC has much better computation power comparing to something like #RaspberryPi. I had plans for a #homeserver and I wanted to use my #LibreComputer #Alta and utilize its #npu.

Libre Computer boards have really good prices comparing to the performance they provide comparing to other ARM SBCs such as #RPi. However, comparing them with a mini or even #microPC, an old micro PC provides better computation power.

LibreComputer #RenegadeElite features a #Rockchip #rk3399, 4GB DDR4 and costs 76 USD:

On the other hand, this renewed #HP #EliteDesk is 100 USD and with far better specs:

Maybe it's not fair compare a renewed product with a brand new one. But it seems for having a homeserver to #selfhost things, if we factor out power usage, an old mini PC is better than a new ARM SBC.

However, if we also consider power usage, the abovementioned LibreComputer board consumes only 15 W under full load. And the old Ryzen 5 on that HP mini PC has a TDP of 35 W. This affects running cost of your homeserver and also the cost for the #UPS. But for myself, there isn't a big deal between 15W and 35W.

Edit: Comments or advises are very welcome!

Edit2: On second thought, I won't go for second hand or renewed. I want to use them as servers and this means 100% uptime. And I doubt second hand ones will survive, especially given the more power they consume which generates heat. And since my budget for a homeserver is 100 USD, ARM SBCs seem to be the only choice. I can research more though.

Okay so I need to make my own split mechanical keyboard. But I want my keyboard to have dual functions. Both a keyboard and a "micro" PC. After long discussions in Rust Offtopic Matrix room and then Rust Embedded room, I think it's a good idea to use Milk V Duo as the processor for my keyboard. And then add video output(HDMI), speaker/buzzer, microphone and Wifi. A shortcut on the device will switch between micro PC and ordinary keyboard.

An advantage of sophogo sg2002 SoC is that the TRM is fully available in English. This will be useful when I want to enter kernel development later. For now I will just do Linux on it.

A Milk V Duo with 512MB RAM and with Wifi costs only 18 USD.
