TP4056 / TC4056A Lithium Battery Charger and Protection Module, #motionsensor #nightlight #LEDlight #deanwong #drmobileslimted #davidlimnz #0800429429

5th Septmber 2021, Auckland, New Zealand: 

This module is made for charging rechargeable lithium batteries using the constant-current/constant-voltage (CC/CV) charging method. In addition to safely charging a lithium battery the module also provides necessary protection required by lithium batteries. See below concerning the protection features this module provides.

Protection Features

This module uses the TP4056 / TC4056 Li-Ion charge controller IC and a separate protection IC. There are other types of modules on the market that use the TP4056 / TC4056 but lack any protection circuits or ICs to provide the necessary protection needed with lithium batteries. This module uses both the TP4056 / TC4056 and the DW01A Li-Ion battery protection IC, which together in combination provide the following protection features:

Manage the constant current to constant voltage charging of a connected lithium battery

Over-discharge protection - keeps your battery from being discharged below 2.4V, a healthy minimum voltage level for your battery

If a connected battery has been discharged below 2.4V the module will cut output power from the battery until the battery voltage has been re-charged above 3.0V (the over-discharge release voltage), which at that time the module will again allow discharge of power from the battery to a connected load. Although the module cuts output power from the battery during an over-discharge situation, it still allows charging of the battery to occur through the parasitic diode of the discharge control MOSFET (FS8205A Dual MOSFET).

Overcharge protection - the module will safely charge your battery to 4.2V

Overcurrent and short-circuit protection - the module will cut the output from the battery if the discharge rate exceeds 3A or if a short-circuit condition occurs

Soft-start protection limits inrush current

Trickle charge (battery reconditioning) - if the voltage level of the connected battery is less than 2.9V, the module will use a trickle charge current of 130mA until the battery voltage reaches 2.9V, at which point the charge current will be linearly increased to the configured charge current.

Can be powered, for charging, from a USB cable (USB Micro or USB C) or the + and - connections, see Power Supply Options Diagram below. The power source needs to be able to provide at least 1A for the charger to correctly charge a connected battery. Most modern phone/USB chargers can provide 1A or more; refer to the label on your phone charger to verify. If you use a USB cable, make sure that it is made to carry at least 1A.

Includes two indicator LEDs. Red LED indicates charging. Blue LED indicates charge complete.

The charge current can be configured externally with the Rprog resistor (R3, see below diagram). The datasheet for the TP4056 (refer to link in resources section below) includes a table and equation for what resistor values to use for configuring different charge currents.

The module uses a very small amount of current (in the micro amps) whenever it is connected to a battery. It is fine to leave it connected to a battery for long periods, but if you plan to not charge the battery within four months then we recommend disconnecting the module from the battery.

You can connect two lithium battery cells in parallel to form an equivalent single cell battery with a total capacity of twice that of the individual single cells, but we do not recommend connecting more than two cells at a time to this module. Refer to the Two Parallel Cell Connection diagram below. Care must be taken when setting up this type of configuration; refer to Precautionary Note 1 concerning precautions to connecting parallel cells.

NOTE: Due to the nature and characteristics of lithium-ion batteries Addicore is not responsible or liable for any damages, malfunction, injuries, fire, burns, or any other consequences or results that may occur with incorrect or correct use of this module or any battery, device, or item this module is used with, including following or using any instructions, guidance, or direction of any kind from Addicore or others. By purchasing this product you accept the preceding.


Note 1: Caution must be used when connecting two cells in parallel. Both cells must be at the same voltage level otherwise if one cell has a lower voltage than the companion cell the higher voltage cell will discharge into the lower voltage cell in an attempt to bring the two cells to the same voltage, which will eventually balance out, but if the voltages of the two cells differ enough the resulting current through both cells can be high enough to cause the cells to overheat or worse.

When charging two parallel cells connected to this charge module the charge current through each cell will be half of the total charge current from the charge module, that is if each of the cells have equivalent voltage levels.

Covid 19 coronavirus Delta outbreak: Seven Covid cases at AUT; Auckland lockdown for several weeks likely - expert

More AUT students have tested positive for Covid-19 today.

The university this evening said a total of seven students tested positive for Covid-19 but it was not clear if three of them were on campus during their infectious period.

Meanwhile, a Covid-19 modeller says Auckland will likely be in alert level 4 for at least several weeks after the number of cases in the community grew to 107 today.

Professor Shaun Hendy said it was becoming clear New Zealand was dealing with a cluster reaching the upper limit of expectations when it was detected in Auckland nearly a week ago.

"For the rest of the country we will have to wait until later in the week to see if they remain clear, in which case, an alert level shift could be considered on Friday.

Prime Minister Jacinda Ardern announced this afternoon the country will remain at alert level 4 until 11.59pm on Friday August 27. Auckland will remain in alert level 4 until 11.59pm on Tuesday August 31.

There are 99 cases in Auckland and eight in Wellington.

Director general of health Ashley Bloomfield said this afternoon the new cases in Wellington were connected with and were close contacts of known cases.

He said all but one had been in isolation throughout their infectious period.

How will #Coronavirus #Delta evolve? Here’s what the theory tells us. #drmobileslimited #toll0800429429 #tel095515344

SARS-CoV-2 Delta variant, also known as lineage B.1.617.2, or Indian variant is a variant of lineage B.1.617 of SARS-CoV-2, the virus that causes COVID-19. It was first detected in India in late 2020. The World Health Organization named it the Delta variant on 31 May 2021.


The Covid-19 pandemic is a dramatic demonstration of evolution in action. Evolutionary theory explains much of what has already happened, predicts what will happen in the future and suggests which management strategies are likely to be the most effective.

For instance, evolution explains why the Delta variant spreads faster than the original Wuhan strain. It explains what we might see with future variants. And it suggests how we might step up public health measures to respond.

But Delta is not the end of the story for SARS-CoV-2, the virus that causes Covid-19. Here's what evolutionary theory tells us happens next.

Remind me again, how do viruses evolve?

Evolution is a result of random mutations (or errors) in the viral genome when it replicates. A few of these random mutations will be good for the virus, conferring some advantage. Copies of these advantageous genes are more likely to survive into the next generation, via the process of natural selection.

New viral strains can also develop via recombination, when viruses acquire genes from other viruses or even from their hosts.

Generally speaking, we can expect evolution to favour virus strains that result in a steeper epidemic curve, producing more cases more quickly, leading to two predictions.

First, the virus should become more transmissible. One infected person will be likely to infect more people; future versions of the virus will have a higher reproductive or R number.

Second, we can also expect evolution will shorten the time it takes between someone becoming infected and infecting others (a shorter "serial interval").

Both these predicted changes are clearly good news for the virus, but not for its host.

Aha, so that explains Delta

This theory explains why Delta is now sweeping the world and replacing the original Wuhan strain.

The original Wuhan strain had an R value of 2-3, but Delta's R value is about 5-6 (some researchers say this figure is even higher). So someone infected with Delta is likely to infect at least twice as many people as the original Wuhan strain.

There's also evidence Delta has a much shorter serial interval compared with the original Wuhan strain.

This may be related to a higher viral load (more copies of the virus) in someone infected with Delta compared with earlier strains. This may allow Delta to transmit sooner after infection.

A higher viral load may also make Delta transmit more easily in the open air and after "fleeting contact".

Do vaccines affect how the virus evolves?

We know Covid-19 vaccines designed to protect against the original Wuhan strain work against Delta but are less effective. Evolutionary theory predicts this; viral variants that can evade vaccines have an evolutionary advantage.

So we can expect an arms race between vaccine developers and the virus, with vaccines trying to play catch up with viral evolution. This is why we're likely to see us having regular booster shots, designed to overcome these new variants, just like we see with flu booster shots.

Covid-19 vaccines reduce your chance of transmitting the virus to others, but they don't totally block transmission. And evolutionary theory gives us a cautionary tale.

There's a trade-off between transmissibility and how sick a person gets (virulence) with most disease-causing microorganisms. This is because you need a certain viral load to be able to transmit.

If vaccines are not 100 per cent effective in blocking transmission, we can expect a shift in the trade-off towards higher virulence. In other words, a side-effect of the virus being able to transmit from vaccinated people is, over time, the theory predicts it will become more harmful to unvaccinated people.

How about future variants?

In the short term, it's highly likely evolution will continue to "fine tune" the virus:

• its R value will continue to increase (more people will be infected in one generation);

• the serial interval will decrease (people will become infectious sooner);

• variants will make vaccines less effective (vaccine evasion).

But we don't know how far these changes might go and how fast this might happen.

Some scientists think the virus may already be approaching "peak fitness". Nevertheless, it may still have some tricks up its sleeve.

The UK government's Scientific Advisory Group for Emergencies (SAGE) has recently explored scenarios for long-term evolution of the virus.

It says it is almost certain there will be "antigenic drift"; accumulation of small mutations leading to the current vaccines becoming less effective, so boosters with modified vaccines will be essential.

It then says more dramatic changes in the virus ("antigenic shift"), which might occur through recombination with other human coronaviruses, is a "realistic possibility". This would require more substantial re-engineering of the vaccines.

SAGE also thinks there is a realistic possibility of a "reverse zoonosis", leading to a virus that may be more pathogenic (harmful) to humans or able to evade existing vaccines. This would be a scenario where SARS-CoV-2 infects animals, before crossing back into humans. We've already seen SARS-CoV-2 infect mink, felines and rodents.

Will the virus become more deadly?

Versions of the virus that make their host very sick (are highly virulent) are generally selected against. This is because people would be more likely to die or be isolated, lowering the chance of the virus transmitting to others.

SAGE thinks this process is unlikely to cause the virus to become less virulent in the short term, but this is a realistic possibility in the long-term. Yet SAGE says there is a realistic possibility more virulent strains might develop via recombination (which other coronaviruses are known to do).

So the answer to this critical question is we really don't know if the virus will become more deadly over time. But we can't expect the virus to magically become harmless.

Will humans evolve to catch up?

Sadly, the answer is no. Humans do not reproduce fast enough, and accumulate enough favourable mutations quickly enough, for us to stay ahead of the virus.

The virus also does not kill most people it infects. And in countries with well-resourced health-care systems, it doesn't kill many people of reproductive age. So there's no "selection pressure" for humans to mutate favourably to stay ahead of the virus.

What about future pandemics?

Finally, evolutionary theory has a warning about future pandemics.

A gene mutation that allows a virus in an obscure and relatively rare species (such as a bat) to gain access to the most common and widely distributed species of large animal on the planet - humans - will be strongly selected for.

So we can expect future pandemics when animal viruses spill over into humans, just as they have done in the past.

Covid 19 冠狀病毒:達美航空將如何發展?這是科學告訴我們的


Covid-19 大流行是行動中進化的戲劇性展示。進化論解釋了大部分已經發生的事情,預測未來會發生什麼,並建議哪些管理策略可能是最有效的。

例如,進化解釋了為什麼 Delta 變種比原始武漢菌株傳播得更快。它解釋了我們可能會在未來的變體中看到什麼。它建議我們如何加強公共衛生措施來應對。

但是對於導致 Covid-19 的病毒 SARS-CoV-2 而言,Delta 並不是故事的結束。這是進化理論告訴我們接下來會發生的事情。





首先,病毒應該變得更容易傳播。一名感染者可能會感染更多人;該病毒的未來版本將具有更高的繁殖或 R 值。



啊哈,這就解釋了 Delta

這個理論解釋了為什麼 Delta 現在正在席捲全球並取代原來的武漢菌株。


還有證據表明,與最初的武漢菌株相比,Delta 的序列間隔要短得多。

這可能與感染 Delta 的人比早期毒株更高的病毒載量(更多的病毒拷貝)有關。這可能允許 Delta 在感染後更快地傳播。

更高的病毒載量也可能使 Delta 在露天和“短暫接觸”後更容易傳播。


我們知道,旨在抵禦最初的武漢病毒株的 Covid-19 疫苗對 Delta 有效,但效果較差。進化論預測了這一點;可以逃避疫苗的病毒變體具有進化優勢。


Covid-19 疫苗可降低您將病毒傳播給他人的機會,但它們並不能完全阻止傳播。進化論給了我們一個警示故事。


如果疫苗在阻斷傳播方面不是 100% 有效,我們可以預期權衡會轉向更高的毒力。換句話說,該病毒能夠從接種疫苗的人身上傳播的副作用是,隨著時間的推移,該理論預測它對未接種疫苗的人的危害會更大。



• 其R值會不斷增加(一代人會感染更多的人);

• 序列間隔將減少(人們會更快地具有傳染性);

• 變異會降低疫苗的效力(逃避疫苗)。



英國政府的緊急情況科學諮詢小組 (SAGE) 最近探索了病毒長期進化的情景。



SAGE 還認為存在“反向人畜共患病”的現實可能性,導致病毒可能對人類更具致病性(有害)或能夠逃避現有疫苗。這將是 SARS-CoV-2 感染動物,然後再傳播回人類的情況。我們已經看到 SARS-CoV-2 感染水貂、貓科動物和囓齒動物。



SAGE 認為,這個過程在短期內不太可能導致病毒的毒性減弱,但從長遠來看,這是一個現實的可能性。然而,SAGE 表示,通過重組(已知其他冠狀病毒會這樣做),有一種現實的可能性可能會產生更具毒性的菌株。

Covid 19 coronavirus Delta outbreak: 35 new community cases today, total cases in outbreak now 107

Covid 19 coronavirus Delta outbreak:
35 new community cases today,
total cases in outbreak now 107

23rd August, 2021:  There are 35 new cases of Covid-19 in the New Zealand community to confirm today. Of these 33 are in Auckland and two are in Wellington.

This brings the total number in the community to 107. Of these 99 are in Auckland and eight are in Wellington.

Prime Minister Jacinda Ardern and director general of health Dr Ashley Bloomfield will front a press conference at 4pm to announce any challenges to alert levels. New Zealand is currently in lockdown until 11.59pm tomorrow.

All of today's new cases are either in or currently being transferred to managed isolation facilities.

The Ministry of Health says it was not unexpected to see a rise in cases.

There are also three new border cases all who are in managed isolation facilities.

There are now 334 visits to 248 locations of interest listed by the Ministry of Health. The vast majority of these are in Auckland, with at least 12 in Wellington and a few scattered across the North Island, as well as two flights between Auckland and Wellington.

The latest exposure sites include KFC in Pt Chevalier between 9pm and 10pm on Friday August 13.

There is also a new location outside Auckland, a visit to the Johnsonville Mobil petrol station in Wellington on Tuesday between 8.20pm and 8.35pm.

An additional south Auckland supermarket is now on the list with an infected shopper visiting PaknSave Clendon Park on Monday August 16 between 7pm and 7.30pm.

There is also a corner store in the same suburb, Clendon Dairy on Roscommon Rd that is also a potential exposure site. The Ministry of Health says if you visited the store between 11.30am and 12pm on Tuesday August 17 you must isolate at home for 14 day, get tested immediately and again on days 5 and 12 after last exposure.

More public bus rides between Glen Eden and Green Bay have also been added.

So far 13,230 contacts have been identified with less than half - 6773 - contacted by public health staff and self isolating.

The majority of the 13,230 contacts are close contacts and the number is expected to rise throughout the day as records are fully processed.

Public health staff are now reaching out to the remaining 6,457 contacts who are yet to be reached.

The Million Dollar Question: Is the iPhone XS Waterproof? #drmobileslimited #0800429429 #aucandrepair

The iPhone XS has great water resistance, but it's far from waterproof

The iPhone XS is the first member of the lineup to sport an IP68 water resistance rating. This means that the iPhone XS is protected against "harmful dust," as well as submersion in more than one meter of water for up to 30 minutes. Apple says, in fact, that the iPhone XS and iPhone XS Max could survive submersion in up to two meters of water for 30 minutes.

But this is a far cry from being waterproof. If you leave your iPhone in the water long enough, that water will still eventually enter the device and start to effect the electronics in the phone, and eventually cause it to fail completely. While you might get lucky if your phone takes a dive of say, three meters, there's no guarantee, so you'll want to be careful around pools, lakes, and other bodies of water.

* To identify your iPhone model number, see For details on LTE support, contact your carrier and see Cellular technology support is based on iPhone model number and configuration for either CDMA or GSM networks.

  1. Available space is less and varies due to many factors. A standard configuration uses approximately 10GB to 12GB of space (including iOS and preinstalled apps) depending on the model and settings. Preinstalled apps use about 4GB, and you can delete these apps and restore them.
  2. Size and weight vary by configuration and manufacturing process.
  3. iPhone XS and iPhone XS Max are splash, water, and dust resistant and were tested under controlled laboratory conditions with a rating of IP68 under IEC standard 60529 (maximum depth of 2 meters up to 30 minutes). Splash, water, and dust resistance are not permanent conditions and resistance might decrease as a result of normal wear. Do not attempt to charge a wet iPhone; refer to the user guide for cleaning and drying instructions. Liquid damage not covered under warranty.
  4. Data plan required. Gigabit-class LTE, LTE Advanced, LTE, VoLTE, and Wi-Fi calling are available in select markets and through select carriers. Speeds are based on theoretical throughput and vary based on site conditions and carrier. For details on LTE support, contact your carrier and see
  5. FaceTime calling requires a FaceTime-enabled device for the caller and recipient and a Wi-Fi connection. Availability over a cellular network depends on carrier policies; data charges may apply.
  6. Standard Dynamic Range video content only.
  7. Siri may not be available in all languages or in all areas, and features may vary by area. Internet access required. Cellular data charges may apply.
  8. All battery claims depend on network configuration and many other factors; actual results will vary. Battery has limited recharge cycles and may eventually need to be replaced by Apple service provider. Battery life and charge cycles vary by use and settings. See and for more information.
  9. Testing conducted by Apple in August 2018 using preproduction iPhone XS and iPhone XS Max units and software and accessory Apple USB-C Power Adapters (18W Model A1720, 29W Model A1540, 30W Model A1882, 61W Model A1718, 87W Model A1719). Fast-charge testing conducted with drained iPhone units. Charge time varies with environmental factors; actual results will vary.
  10. Qi wireless chargers sold separately.
  11. Use of eSIM requires a wireless service plan (which may include restrictions on switching service providers and roaming, even after contract expiration). Not all carriers support eSIM. Use of eSIM in iPhone may be disabled when purchased from some carriers. See your carrier for details. To learn more, visit
