> No BSP, no kernel source, no vendor documentation — just a DTB extracted from the stock Android firmware and rebuilt from there.
Judging from the build.sh, it looks like this is just using unmodified upstream u-boot and tools from the rockchip-linux repository, so "from scratch" is really just analyzing the DTB to see what drivers need to be loaded?
> The TL-SG108 uses a 4Mbit (512KiB) SPI flash chip from Cfeon, which is too small to contain any assets for a web management interface
The https://github.com/logicog/RTLPlayground alternative firmware for RTL8372/RTL8373 based 2.5GBit Switches does fit into 512KiB, including web management interface.
I've been mounting my 3.5" hard drives on those "fad" rubber band 5.25" drive bay adapters for decades and have not noticed any increased failure rate at all. Sure, seek time may be worse, but the reduced noise has been worth it for me.
Not OP, but I installed a "Balcony solar" 1.4kWp panels 2.4kWh battery system on my parents garage. The only subsidy was the tax free purchase of the components (we did file for an additional tax break with the city, but they had already run out of funds for that because it is so popular). You also save a lot of money on installation costs.
Cost breakdown:
- 400 EUR 2.4kWh 48V battery
- 320 EUR 4x 360W solar panels
- 200 EUR 800W microinverter
- ~200 EUR for helping hands when getting the panels onto the flat roof
- 160 EUR flat roof mounting equipment
- 153 EUR solar cable, connectors and crimping tool
- 115 EUR MPPT charge controller and cables
- 95 EUR electrics (e.g. fuses, dc/dc converter for OpenDTU)
- 50 EUR other assorted costs
So about 1693 EUR in total.
Total yield after 1.3 years: 1715 kWh (including power fed back into the grid)
Of that, discharged from battery: 488 kWh (battery already paid back ~146 EUR)
At the current energy costs, 1715 kWh would be ~514 EUR imported from grid
> you are recommended to get the shingles vaccine instead of the chickenpox vaccine since the way the disease presents and how the body reacts to it changes with age (technically shingles can happen at any age but generally herpes zoster presents as shingles instead of chickenpox the older you get).
If the underlying virus is the same, what is different between the vaccines? How it presents shouldn't matter as much?
