Readit NewsCost 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
Sure you are more likely to have it the older you are but even then you are unlikely to have all the strains. The vaccine covers like 9 or 10 different strains so it can protect you from the other strains even if you already have one of them.
It's generally only when you get into the 60s and up that the justification for not recommending the vaccine changes. Once you get into those later years the immune response changes a bit and you get new concerns.
An example being herpes zoster (chickenpox) where after a certain age 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?
When I first started the project in 2012-13, Vitesse was just as NDA-happy and I ruled them out. The original roadmap called for a 24-port switch with 24 individual TI DP83867 SGMII PHYs on three 8-port line cards.
I poked at a vsc73xx-based switch in the past and wrote my own test firmware, but had problems with packet loss since I didn't do all the necessary phy initializations I guess, in case this might be of interest: https://github.com/ranma/openvsc73xx/blob/master/example/pay...
Also on the device I had the EEPROM was tiny and the code is loaded from EEPROM into RAM, you were pretty much stuck with 8051 assembly that had to fit into the 8KiB of onchip RAM :)
Looks like the PPKII can do up to 1A.
Many multicell BMS already have this kind of "power shedding" capability. They use it for cell balancing - to equalize voltage between cells with slightly different characteristics. This is desirable despite the power waste, because it reduces wear, increases charging efficiency and allows battery packs to last longer.
Some battery packs are also designed to be able to dump enough power into heat to be able to keep the batteries warm during extreme cold.
Similarly, the heatsinking capacity of the battery is designed for charging/discharging losses (say 5% of charge/discharge power).
At least in some cases it is sufficient to change the phone SKU id (which requires temporary rooting) to the Japan SKU id to unlock the Osaifu-Keitai functionality on a non-Japan phone. I'm not sure if this means that the secure element had the necessary keys provisioned all along, or just that the Osaifu-Keitai app then provisions it on first use.
And yet, no big leap in ReactOS (at least for now).
