Let’s Get it Started (HA!)
Let’s get it started IN HERE!
Here’s your start-up guide for the Tamagotchi Smart, translated by yours truly directly on top of the official 25th Anniversary Set instruction guide!
Tumblr media Tumblr media Tumblr media Tumblr media
As I haven’t translated Page 19 yet, here are the approved USB Charging devices:
Anker PowerPort mini
Anker PowerPort 2 Elite
Elecom AVA-ACUAN007
Elecom MPA-ACU07
Sanwa Supply ACAIP49 Series
Sanwa Supply ACAIP55BK
Please be sure to take voltage differences into account! Japan’s electricity runs at 100V. You can fudge it to a certain degree in the US (110V), but if you’re in Europe (220V) it’s crucial to make sure your charger utilizes a step-down converter so the battery charges properly. If you fry the battery, that’s it! No more switching out LR-44s with a screwdriver like in 1996!! I hope you’ll use this translation to take the best possible care of your Tamagotchi Smart when it arrives.
Rest of the manual to come, probably next weekend!

Day 10
Post#10                        Jan 21,  2020                 Tue 21:11 PM
I was reading about Indian railway using non-standard voltage appliance, i.e., 100V appliances to avoid theft.
One thing led to another, and I got to know, every country has their own voltage standard and frequency.
The voltage preference goes deep into “Edison Vs Tesla” war.
Edison came up with DC systems, which operated on 110V, and made sense too, as high voltages were dangerous, but DC was not suitable for long distance transmission.
Tesla, when introduced AC systems, made careful calculation and preferred 220V and 60Hz as standard, putting him at odd with Edison.
When the German company AEG built the first European generating facility, its engineers decided to fix the frequency at 50 Hz, because the number 60 did not seem much metric friendly (1, 2, 5). At that time, AEG had a virtual monopoly and their standard spread to the rest of the continent.
US companies stick to 60Hz, making it a standard across the continent.
Coming to Voltage part. originally Europe was 120 V too, just like Japan and the US today. After World War II, Europe adopted Tesla’s preferred voltage, 220/240. Since many places weren’t as well “connected”, and lots of the power grid was destroyed anyways during the war, it made sense to to increase voltage to get more power with fewer losses and less voltage drop from the same copper wire diameter.
 At the time the US also wanted to change but because of the cost involved to replace all electric appliances, they decided not to. So they stick to 110V, but 60Hz frequency.
Japan had equipment from Germany, as well as from the USA, explaining its “split frequency”, despite using voltage and plug standards related to the USA, i.e, 110V.
So, I guess, for next time, if I am travelling to another country, I should also keep in mind about their electrical standards, and arrange for appropriate converters.

All You Need To Know About Online Digital Gadgets
Tumblr media
It is a first-rate enjoy to travel remote places. However, if you need to carry electronics with you, you want to ensure that the voltage of your most durable Earbuds is correct. If it isn't, you want to convert the voltage until it reaches the correct voltage. By checking out the subsequent pointers, you may recognize the easy approaches to safely take your digital gadgets overseas.
As the first step, the voltage of all your devices which you need to take remote places must be checked. You will discover that the device most likely will say 100v or 110v. If you find that your device says 110v - 220v, it approach that the device comes in dual voltage so you do no longer must convert the voltage in case you want to carry it with you.
If you discover that the tool isn't dual voltage, the second one step that you ought to do is to shop for the small step-down converter or the transformer for assisting you converting the voltage. In this step, you want to make sure that the wattage on the converter is certainly sufficient for your tool. For example, if the tool desires 50W, the transformer that you'll want is at the least 50W as nicely.
Tumblr media
For the third step, while your device and your converter are prepared, you can also want to apply a plug adapter. The use of this best jump starter for v8 engines absolutely depends on where you're going to cross. Basically, maximum gadgets that you may purchase inside the USA come with skinny, vertical metal prongs, whilst the same old foreign places for the devices is round metal prongs. If you do not buy plug adapter, you'll find that your tool might not match into the stores of the vicinity which you visit.
Lastly, if you have a plan to live overseas for a few years, it will be a great if you could replace all your digital gadgets due to the fact the usage of converter can in all likelihood wear it out.
Charger is one of the maximum important gadget of gadgets, as without a charger it would be difficult for the device to paintings. Therefore, you want to maintenance your charger as well by means of coiling it in the correct method as a defective charger can reason extra complications which include electric powered shocks.
In case your machine has stopped functioning or if something has long gone wrong with it, do now not try to open and restore except you're certified to do so. Opening and fixing the tool might simply make the scenario worse.

How to use the power adapter safely?
A long period of power on will keep the adapter working and affect its service life. Also, take care of the connection between the power cord and the adapter so that the cord is not bent at a dead Angle, which may break the cord. The adapter connection should also avoid bending, otherwise it will cause bad contact. Although adapters operate at a broadband operating voltage ranging from 100V to 240V, they can also cause damage if used with an unstable voltage. So how to use the power adapter safely?
Tips for safe use of power adapters
As we all know, the laptop power adapter is made up of two parts, one is the power adapter, the other is the power cord and the socket for the laptop. When the part of the power adapter fails, sometimes we just need to change the part. The socket side does not need to be changed. So now the question is, can the same nominal voltage, if the output current is different, be used on the same laptop? The basic principle is that a large nominal current power supply can replace a small nominal current power supply.
Notebook adapter is actually a high precision, high efficiency switch type voltage regulator power supply, its role is to convert 220V ac mains power into low-voltage direct current, for the normal work of the notebook to provide stable power, it is even known as the notebook "power source". Because the power adapter is a switching power supply that works in the state of high voltage and large current, the workload is heavy, and it is a fully closed structure, there is no cooling hole on the shell, and there is no fan to assist the heat dissipation, so the internal temperature of the power adapter is very high when it is working. Especially in the hot summer, touch the surface can feel hot, the internal temperature is higher. Therefore in the daily office, entertainment, to it proper maintenance and maintenance.
Create good heat dissipation. In hot summer, we can put the power adapter side to the environment. When using the laptop in a high temperature environment, the power adapter should be placed away from direct sunlight and ventilated place; Do not put the power adapter in the notebook near the heat outlet, otherwise not only the power adapter heat emission does not go out, but also absorb a part of the heat to increase the adapter and air contact area, so that the adapter heat better out. For better heat dissipation, you can also pad the adaptor with a narrow plastic or metal block between the adaptor and the table to increase the air convection around the adaptor and increase the adaptor's heat dissipation.
Any power supply has some internal resistance, so when the power supply outputs the current, there will be an internal voltage drop, which is equal to the output current times the internal resistance. The voltage drop causes two things, one is to produce heat, which is equal to the output current squared times the internal resistance, so the supply will be hot, and the other is to change the output voltage to the nominal voltage minus the internal voltage drop, causing the output voltage to drop. When the output current reaches this value, the output voltage is reduced to 95% of the nominal voltage or other ratio. Manufacturers can set higher or lower ratio according to the different needs of the load products. This current value is the nominal current.
When the power adapter is found to be too hot should immediately stop using, if a short time of use are found to be very hot, then may be the use of the power adapter and notebook original power adapter voltage current difference is relatively large, it is recommended to compare the original standard current voltage. If there is any deviation, please replace it immediately, otherwise it may burn out the computer and cause unnecessary loss.
Three major points of insulation for power adapters
A lot of people will hear in the new product development process of switching power supply adapter, not only the need for a comprehensive consideration of product packaging, circuit design, heat design and anti electromagnetic interference, insulation cover design is also a very important design link. This article will briefly analyze insulation cover design, help engineer a thorough knowledge of the insulation cover design key points of the adapter, power adapter in the process of working, suddenly sometimes appear in the circuit surge voltage is higher than the risk, in order to ensure normal operation of the circuit, it must take the appropriate insulation screen technology. The following power adapter manufacturers will carefully talk about the power adapter insulation three major points. Usually, more common insulation cover technology is generally divided into the following types:
First of all, we are more common insulation technology is strengthening insulation technology. This technique is one of many insulation systems designed to avoid electric shock and is functionally equivalent to double insulation. In circuit design using reinforced insulation, the minimum thickness of a single layer used inside is greater than or equal to 0.4mm, so that several layers of insulation can be secured, but each layer cannot be tested alone.
Another common method of insulation in China is base insulation. This technology is the most basic insulation method to avoid switching power supply adapters from being shocked. It is also a relatively clear insulation technology introduced in various textbooks at present. This paper will not be described here too much. However, the foundation insulation alone is not absolutely safe, and the engineer needs to reach the safety request through additional insulation and cover ground secondary cover, such as insulation between coils.
Different types of circuits require different types of insulation:
1, this kind of equipment to take cover ground, that is, metal chassis to cover ground, as a level 1 cover. Only foundation insulation, such as station communication power supply, is required between any risk voltage parts and the chassis.
2, use double insulation and reinforced insulation, no metal case and ground screws, such as portable charger.
It is powered by SELV source and external potential risk-free voltage generating source, thus requiring only foundation insulation, such as circuit board power supply.

For better heat dissipation, you can also pad the adaptor with a narrow plastic or metal block between the adaptor and the table to increase the air convection around the adaptor and increase the adaptor's heat dissipation.
Any power supply has some internal resistance, so when the power supply outputs the current, there will be an internal voltage drop, which is equal to the output current times the internal resistance. The voltage drop causes two things, one is to produce heat, which is equal to the output current squared times the internal resistance, so the supply will be hot, and the other is to change the output voltage to the nominal voltage minus the internal voltage drop, causing the output voltage to drop. When the output current reaches this value, the output voltage is reduced to 95% of the nominal voltage or other ratio. Manufacturers can set higher or lower ratio according to the different needs of the load products. This current value is the nominal current.
When the power adapter is found to be too hot should immediately stop using, if a short time of use are found to be very hot, then may be the use of the power adapter and notebook original power adapter voltage current difference is relatively large, it is recommended to compare the original standard current voltage. If there is any deviation, please replace it immediately, otherwise it may burn out the computer and cause unnecessary loss.
Three major points of insulation for power adapters
A lot of people will hear in the new product development process of switching power supply adapter, not only the need for a comprehensive consideration of product packaging, circuit design, heat design and anti electromagnetic interference, insulation cover design is also a very important design link. This article will briefly analyze insulation cover design, help engineer a thorough knowledge of the insulation cover design key points of the adapter, power adapter in the process of working, suddenly sometimes appear in the circuit surge voltage is higher than the risk, in order to ensure normal operation of the circuit, it must take the appropriate insulation screen technology. The following power adapter manufacturers will carefully talk about the power adapter insulation three major points. Usually, more common insulation cover technology is generally divided into the following types:
First of all, we are more common insulation technology is strengthening insulation technology. This technique is one of many insulation systems designed to avoid electric shock and is functionally equivalent to double insulation. In circuit design using reinforced insulation, the minimum thickness of a single layer used inside is greater than or equal to 0.4mm, so that several layers of insulation can be secured, but each layer cannot be tested alone.
Another common method of insulation in China is base insulation. This technology is the most basic insulation method to avoid switching power supply adapters from being shocked. It is also a relatively clear insulation technology introduced in various textbooks at present. This paper will not be described here too much. However, the foundation insulation alone is not absolutely safe, and the engineer needs to reach the safety request through additional insulation and cover ground secondary cover, such as insulation between coils.
Different types of circuits require different types of insulation:
1, this kind of equipment to take cover ground, that is, metal chassis to cover ground, as a level 1 cover. Only foundation insulation, such as station communication power supply, is required between any risk voltage parts and the chassis.
2, use double insulation and reinforced insulation, no metal case and ground screws, such as portable charger.
It is powered by SELV source and external potential risk-free voltage generating source, thus requiring only foundation insulation, such as circuit board power supply.

How to use the power adapter safely?
A long period of power on will keep the adapter working and affect its service life. Also, take care of the connection between the power cord and the adapter so that the cord is not bent at a dead Angle, which may break the cord. The adapter connection should also avoid bending, otherwise it will cause bad contact. Although adapters operate at a broadband operating voltage ranging from 100V to 240V, they can also cause damage if used with an unstable voltage. So how to use the power adapter safely?
Tips for safe use of power adapters
As we all know, the laptop power adapter is made up of two parts, one is the power adapter, the other is the power cord and the socket for the laptop. When the part of the power adapter fails, sometimes we just need to change the part. The socket side does not need to be changed. So now the question is, can the same nominal voltage, if the output current is different, be used on the same laptop? The basic principle is that a large nominal current power supply can replace a small nominal current power supply.
Notebook adapter is actually a high precision, high efficiency switch type voltage regulator power supply, its role is to convert 220V ac mains power into low-voltage direct current, for the normal work of the notebook to provide stable power, it is even known as the notebook "power source". Because the power adapter is a switching power supply that works in the state of high voltage and large current, the workload is heavy, and it is a fully closed structure, there is no cooling hole on the shell, and there is no fan to assist the heat dissipation, so the internal temperature of the power adapter is very high when it is working. Especially in the hot summer, touch the surface can feel hot, the internal temperature is higher. Therefore in the daily office, entertainment, to it proper maintenance and maintenance.

17″ LCD display
Price: $5
Model: Samsung Syncmaster CX711T 
Included: monitor + RGB cable + 220V to 100V converter.
I bought this monitor many years ago, at least more than 6 years. The monitor is still working, but the screen condition is not good - tainted a lot. It seems to be only suitable for those who intend to use it as a secondary display for limited purposes, (e.g., file explore). Since the monitor is too old, I can’t guarantee anything on its performance as well as life. No refund. Not recommended for sensitive design works. 
Note: this monitor both support 110v and 220v. DVI connection is also supported.
