Thanks, I found that already.

But what does it tell us?

What is the connection between LiitoKala and Panasonic - if there is any?

Or is it just that LiitoKala produces something that they claim is similar to the Panasonic 18650?

Litokala manufacture the cells with approval from Panasonic to their specification. Example NCR18650B  https://www.batteryspace.com/prod-specs/NCR18650B.pdf

There are genuine sellers on Lazada. Purchase a single cell and perform weight and capacity test using the data sheet.

When I search in Lazada they have lots of batteries which they claim are Panasonic but looking at the pictures they are from LiitoKala.

It should be noted that failing MOV's can start fires with only a small mains current flow often well below any overcurrent protection. The preferred method is to employ a thermal fuse in series with the MOV. Some circuits provide visual indication when a thermal fuse fails.

MOV's do not always fail in flames and often split open completely breaking the circuit. Its good practice  to occasionally inspect devices placed on supplies to expensive electronics.

What's hi-jacking a plane got to do with conspiracy theories? The facts are out there.

Long before the current true-crime television boom, a 1971 unsolved plane hijacking captivated America. Tom Colbert's journey to track down Cooper (and sell his story to Hollywood) led him to an elaborate theory of collusion involving the FBI and CIA.

huawei is stealing?

 

Huawei has filed the most 5G patents globally as of February 2020 – report

 

Huawei invests hugely in R&D and that is responsible to a large extent for the company’s consistent rise in the global market. The World Intellectual Property Organisation (WIPO) released data for 2019 in April this year showing that Huawei filed a total of 4,411 patents in 2019. This made the company rank as the top corporate filer globally.

You can buy them on Lazada, but they don't look that safe from what I have seen. Flu's and venting being the least of my concerns, but I stand to be corrected.

This post caught my attention because there are many of these cheap water heaters for sale at our local trade markets. I am told they are quite reliable but have been known to discharge hot water that could scald and explode if the gas valve fails to close. Must be installed outside.

Most are poor copies of Japanese products like Rinnai but sadly many do not having the same level of safety devices fitted.

How they work.

A battery powered electronic module detects water flow from a simple switch, starts a spark igniter, opens a gas valve and waits for flame rod signal. If flame is not detected within preset time a flame fail lockout occurs. Fixed gas pressure and water flow sets the output temperature. 

Level of overheat safety protection varies with some models having none on the heat exchanger.

Mind your own business I will lose the weight in my own good time, now leave me alone I have $100 million to spend.

Modern lithium-polymer batteries can be charged at higher currents sometimes as high as two times capacity. This means a 3Ah battery could be charged at 6 amps. 

Regular 5V chargers will have problems delivering enough current over the connecting cable which is why fast chargers negotiate voltage and current values with the phone before delivery. They also employ quality cables capable of handling higher currents.

There are many variables in the fast charging chain. Slow charge time could be down to a faulty component or simply a restricted charge rate set by the phones charge cycle and temperature monitor. 

Plugging the charger into different sockets should make little difference as the chargers have a very wide input voltage range.

Ambient temperature will have an affect on battery charge temperature which can result in the phone adjusting charge rate to compensate. The phones charging management needs to be satisfied with battery condition before allowing a 30 watt + charge to continue.

Fast charging phones problems should be diagnosed by someone who fully understands the method and the type of negotiation employed by the phone.

Some tips that might improve any future design.

The TCRT5000 IR sensor will be a little more accurate when detecting small close proximity objects and the Arduino can read its output directly to filter and set sensitivity.

It would be possible for both clock hands to share one position sensor by placing it just before 12. Similar to the encoder marker pulse method, each hand finds the sensor at speed backs off then approaches slowly until triggered. A defined set of steps then places the hand on 12 and zero is set.

Back in 2003 I spent a short period on the Thai Orange/True Corp project and have stayed in touch with the son of a guy who has several antennas on his land and shop house roof dating back to 1998.

The antennas now average around 80K Baht per year each. I recall two of his contracts pay the tax and the rest do not. 

Capture of the True and Dtac antennas from Google, AIS and some repeaters are on another corner.....

A guess as I have not used it for some time.

The Google earth data is stored under users in a appdata folder if you want to wipe out anything not removed during uninstall.

Google earth has a repair tool somewhere in its menus.

Creative arts is a fabulous idea, I suggest they start with a blank canvas...

Which is the correct type?
 

Type AC (inexpensive)

Type A (not so cheap)

Type B (quite a bit more expensive)

Type F (rather ridiculously priced if you don’t need it)

For home use I would say type A will become the standard when the price feast is over.

In as far as it goes I agree, it is too limited.
 

If you fit the wrong type then it will be more dangerous than not fitting one at all. Because you will be confident that you have RCD protection when you don’t because your equipment is causing it to not function and there will be no way that you will be able to know.

 

 

 

 

 

The problems with DC causing offset at RCD coils has been around forever but recently someone hit the regulation panic button and caused a whole bunch of confusion. This has not been helped by sellers of electrical components jumping on the Tube with dramatic test scenes.

A bunch of LED drivers on a circuit does not mean your RCD is saturated with a DC current. Tests will not always reveal how much of a problem you might have under different load conditions.

The only way to solve this is for everyone to fit a one size fits all solution and take away the guesswork of “have I got the correct RCD fitted”

14 hours ago, sometimewoodworker said:

That depends on the type of RCD that you have and the equipment in your house. If you have a lot/few LEDs then a type a/c may not function you will probably need a type A, as the D.C. from the PSUs can stop an a/c RCD working

But RichCor's statement (post #4) remains valid no matter what RCD type is employed.

I know zip about the pump control body but its PCB LS-8 controller board is in our PCB manufacturers database and referenced by several Shenzhen companies.

The boards come with a few options but all appear to have flow and pressure detection via on board reed switches. Supply in via LN out via VU. 

They have two timers and some simple logic which includes pressure detection flow detection and reset.

The logic diagram suggests the flow switch will likely generate some error if not satisfied within the preset time window. The output relay is controlled by some combination of flow and pressure.

Tell me. what particular "true" story is this season based on?

The 1950's were notable for crime in Kansas City, the story follows crooks from various ethnic backgrounds although the timeline might be a little off for the blacks (quirky Fargo).

Sort of.

 

Mine goes:-

On -red on

Auto -  red stays on until an "off" time

Off- red off

Auto - red stays off until an "on" time

 

It doesn't seem to matter if we are in an on period or not.

 

With red on the floods should activate with the alarm if the switch is wired correctly.

Your results match the common operation perfectly. I am lucky to be close to Chinese engineers who are familiar with most of the common products.

There are several variation of the software used in these timers with most following the same rules.

The program rotates around the 24 hour 7 day clock until it meets a match in the program memory. The event logic is then executed to change output relay status.

When you press the manual button you are changing the timers output status flag directly. When you press the manual button again it will go back into auto leaving the flag permanently as you set it.

The program will then continue in that condition until it finds a change in the programmed events.

Some timers will allow events to be programmed with 'on' event only leaving the 'off' event blank. You could then do the off event in another program slot. The program does no really care as its job is to change relay status only.

You want a picture, here is one. Now which sparky would be able to figure that out without a wiring diagram?

 

Its a Thai rats nest that several on here are quite capable of sketching out without much effort.

Post #19 suggests you need help with the clock etc. See post #37

The OP mentioned in a few posts that 

 

"The alarm system puts out 12 V to trigger the lights."

"Both wires at the bottom contacts of the previous switch go to the 12V relays"

"On the previous switch, 2 tiny wires went from 2 contacts at the bottom to a 12V relays."

"From the 12v relay wires go to a 220V contactor."

"The wires that feed the switch are controlled by a breaker which is labelled floodlights"

 

I'm still a bit confused WHAT the timer load contactor is wired to switch (12vdc, or 220vac). Also, less importantly, what breaker circuit is powering the timer, what breaker circuit is powering the lights through the 12v contactor.

 

Maybe at this point we should ask for pictures?

I think you have helped more than enough already.

To keep stress levels down he should call in someone who understands the system and the programming of digital timers.

Thank you everyone for your suggestions, the lights will work 24/7, end of story.

 

I'm out of here

Unless you are plagued by intruders or false alarms there shouldn't really be any concern over the lights coming on during the day.

Patience is a virtue.
