Sell me your used desktop computer
The Pantip plaza in Bangkok is now some other type of mall. However they do have many used computers for sale there. I bought one recently for my daughter to watch her videos. There is only one floor i think that is dedicated to computers now. Perhaps, if you are in Bkk you can check there again. -

EV Owners … Real life experience & help thread
I'm not sure what this guy's qualifications are, but he's completely wrong. He's wrong about deterioration vs. capacity, and he's wrong about active vs. passive balancing. Tests have shown that LFP batteries cycled between low% and 25% ultimately give more power over their longer lifetime than batteries cycled (sa) 75% to 100% or 50% to 100% etc. The EE video posted elsewhere covers this in detail. Most automakers use active balancers in their battery packs and fairly certain BYD do for example, and I'm sure all NMC battery types do. It's more expensive but more efficient and better. MG use cheaper passive balancing which burns off the energy as heat in higher voltage cells until it matches the lowest voltage cell. This typically only happens above 90%. Active blanacing occurs during all charging & discharging. I have done a google search and cannot find a single article agreeing with what this guy says, all of them disagree with him. AI says The main difference between active and passive balancers is how they manage energy in a battery pack: Active balancers Redistribute energy between cells during charging and discharging, which can improve efficiency and increase run-time. Active balancers can adjust cell voltages faster than passive balancers. Passive balancers Dissipate excess energy from higher voltage cells during the charge cycle. Passive balancers are low cost and have a simple circuit design. However, they can only be used during the charge cycle, and they waste 100% of the balanced power as heat. Here are some other differences between active and passive balancers: Energy efficiency: Active balancers are more efficient than passive balancers because they don't waste energy as heat. Cell life: Active balancers can improve the life expectancy of cells. Balancing time: Active balancers can adjust cell voltages faster than passive balancers. Balancing conditions: Active balancers can work 24 hours a day until the pressure difference between cells is less than a set value. Cell Saviours Active Balancing vs Passive Balancing Differences - Cell Saviors says Active balancing redistributes charge among the cells in a battery pack to ensure that they all have the same state of charge with a dedicated circuit, which monitors the voltage of each cell and adjusts the charging and discharging current accordingly. Active balancing is more accurate and faster than passive balancing. On the other hand, passive balancing relies on Ohm’s Law and the natural cell and balance resistor characteristics to bring cells to the same state of charge. Passive balancing is generally less accurate and slower than active balancing and may take longer to achieve the desired result. EEPower Active and Passive Battery Pack Balancing Methods - Technical Articles says Active Cell Balancing The active cell balancing technique uses inductive charge shuttling or capacitive charge shuttling to transfer the charge between the cells. This technique is proven to be an efficient approach as it transfers energy to where the energy is needed instead of wasting it. However, this demands additional components to be added to the system which in turn translates to increased cost. Passive Cell Balancing The passive cell balancing technique uses the idea of discharging the cells through a bypass route that is mostly dissipative in nature. It is simple and easier to implement than active balancing techniques as the bypass can either be external or be integrated — keeping the system more cost-effective either way. However, since all the excess energy is dissipated as heat, battery run time is adversely impacted and is less likely to be used during discharge. Maxkgo Active vs Passive Balancing: Which is Best for Your Lithium Battery? | MAXKGO News blog says... ·Is active balancing better for electric vehicles? The answer is yes. Active balancing is generally better suited for electric vehicles (EVs). It provides a more efficient and power-saving balancing method. Active balancing is different from passive balancing. Passive balancing releases energy as heat, while active balancing moves energy between cells. This process does not generate much heat. Therefore, it can save more power. This energy-saving method is great for large battery packs in electric vehicles (EVs). The main goal for EVs is to keep the batteries healthy and extend driving time. -

Why Kamala Harris Lost: The Challenges of a Complex Campaign
IMO Trump was effective in tying Harris to Biden, pointing to immigration and living costs under Biden. I understand America originated the aphorism "Fool me once, shame on you. Fool me twice, shame on me". That will be put to the test in the next 4 years. -

Israeli Man Fined for Riding Motorcycle on Phuket Beach, Cites Lack of Signage
It would be nice if you could answer a simple yes/no question with a simple yes/no answer. But he is still an Israeli citizen, Yes or no? https://www.google.co.uk/search?q=can+palestinians+hold+a+passport&sca_esv=43a9cf8e007740e6&sxsrf=ADLYWIIrBNYSNkzkt2KjeURwJ0uEPeaAsQ%3A1731034199056&source=hp&ei=V3wtZ_o06r7Q8Q_M2LGwBQ&iflsig=AL9hbdgAAAAAZy2KZxeWjFF8WEQQVRKwtModHZzwTJ31&oq=Can+Palestinians+hold+a&gs_lp=Egdnd3Mtd2l6IhdDYW4gUGFsZXN0aW5pYW5zIGhvbGQgYSoCCAAyBhAAGBYYHkjUvAFQAFjwiAFwAHgAkAEAmAHUAaABzxyqAQYwLjIyLjG4AQHIAQD4AQGYAhegAoMewgIMECMYgAQYExgnGIoFwgIEECMYJ8ICBxAAGIAEGBPCAgkQABiABBgTGArCAggQABiABBjLAZgDAJIHBjAuMjEuMqAH5IoB&sclient=gws-wiz It is considered one of the lowest ranking passports in the world. Palestinian passport holders have visa-free access to only 35 destinations including Sri Lanka, Dominica, and the Seychelles. There are 193 destinations for which a Palestinian passport holder requires to obtain a visa prior to traveling. https://en.wikipedia.org/wiki/Israeli_citizenship_law#:~:text=While pre-1948 Palestinian Arab,Strip are largely considered stateless. While pre-1948 Palestinian Arab residents of the former mandate and their descendants who remained living in Israel were granted Israeli citizenship in 1980, those resident in the West Bank and Gaza Strip are largely considered stateless.
