Mini portable uninterruptible power supply
Recently i received this mini portable uninterruptible power supply (UPS) that i ordered after seeing a YouTube video of this interesting device. On AliExpress it is advertised as "Mini Portable UPS Router 5V 9V 12V Uninterruptible Power Supply for WiFi, Router Large Capacity Backup Power Adapter Ups Backup"
Is also has a 5V USB outlet and 3 sockets providing 5, 9 and 12 Volt. It has a lithium battery and a circuit to act as UPS when main power stops. On top is an on and of switch and an indicator showing charging level. A European and USA type cable are provided for the main power voltage. Also included are a 'normal'cable and a 'split' cable for the 5,9 and 12 volt connectors.
It is a nice device that maintains power in the event of a power failure and provides some often used voltages. The 5V USB connector is also useful to have. It is not possible to draw all the advertised power at the same time and the power output is somewhat limited. For example it is not possible to power my FritzBox router using this device. If it could power my FritzBox i probably would have ordered immediate a second one to keep my network on in case of a power failure.

Cannibalizing an airplane headset
For experiments i needed a plug to make some connections. As, during the years i have collected airplane headsets i decided to cannibalize one and change it in a test wire, keeping the audio plug on one side and putting crocodile clips on the other side. I did cut the wire and removed some of the plastic insulation. The wires in the airplane headset where even more thin than i expected. Just a a thin metal wire with a thin layer coating on on it. I scratched away the thin coating and after measuring the connections i soldered a small wire to it and put new insulation using heat shrink.
For the three distinct connections i wanted different colors. I had some new black and red alligator clips. Black is used for the common and red for the signal at the tip. An old, not so good, white alligator clip was also used. (On the photo it looks more yellow.) I cleaned the white "alligator jacket" and put the "jacket" on a new good "alligator". The white alligator clip is for the for the middle ring of the plug.
The ear/hearing parts of the airplane headset where not needed yet. However as i already had the heat shrink with hot air gun and my soldering iron and some parts i decided to also make new connections on them.
To one earpiece i added alligator clips, to the other two banana plugs. I hope by adding this connections the hurdle to also use this earpieces, e.g. for a quick test, will be a lot lower. The earpieces where tested with my signal generator and they did work correct.

Mailbag june 2023
A new month just has started, time for a new mailbag post. Two products (The multi-meter and the component tester) where already discussed in separate blog posts. Most other items are for my new to build hobby space.
In this blog i also included the link to the Aliexpress page.

| Waterproof Tile Marker Grout Pen (White) This is not an electronics product, however i decided to keep it in this mailbag list. (I left out some other items like shoes and a phone case.) As i needed one and these pens where relative cheap i ordered two different at different resellers. https://www.aliexpress.com/item/1005005394585022.html?spm=a2g0o.order_list.order_list_main.16.fd011802vagIVz https://www.aliexpress.com/item/1005005586270459.html?spm=a2g0o.order_list.order_list_main.21.fd011802vagIVz |   |
| AC-DC 110-220V Switching power supply module AC-DC isolation input output 5V /12V /100mA /500mA The description of this cheap small (35*25*15mm) power supply module module mentions that it has an input of 110/220 Volt and gives 5V 100mA and 12V 500mA.  I do not yet have a specific project to use it however to me it seems an interesting module. However before keeping it unattended connected to mains power i want to do more testing as sometimes these cheap modules sometimes can be dangerous. https://www.aliexpress.com/item/1005004928760031.html?spm=a2g0o.order_list.order_list_main.31.fd011802vagIVz |   |

I want to use in my new (to build) hobby space for (local) fume extraction when soldering, using glue or other items. Perhaps i also will do some chemical experiments. This item is only for fume extraction, not for dust extraction as it has no dust collector! I did not test it yet, however according to the specs the airflow is 3800 LPM (Cubic Liters per Minute) = 3800*60 = 228000 liter/hour. I don't know yet the size of my new workspace, however e.g. a 3*2.5*5 meter workspace = 37.5 m3 = 37500 liter. This would result in 228000/37500 = ~6 air changes per hour of that complete workspace using one of these small relative cheap ventilators.

Multimeter Angen 683
This post is about my Angen 683 multi-meter that i recently received from AliExpress.
Sometimes people ask, what is a good (or bad) multi-meter and, on internet, you find many opinions about that. It also depends on how you are going to use the meter and it is easy to create multiple blog posts about this topic. In this post i only mention this relative simple ideas about it:
- Any (safe) multi-meter is better than no multi-meter. After a while you probably will need 2 multi-meters (to measure current and voltage at the same time experimenting) however for a starter in electronics start with one.
- If you work with higher voltages (>40 volt) it is important that your meter is safe.
- When measuring it is important that the measuring device does influence the measurement as less as possible: In the current measuring mode the meter needs to have a low resistance and in the voltage mode it needs to have a high resistance. This is especially important when you need to connect and disconnect the meter during an experiment.
- Multi-meters can have additional features (special measurements or special ranges, temperature, frequency, capacitors, data logging, communication to other devices (bluetooth, wifi), voice output, light, robustness etc). Some of these features are now common on most multi-meters, look for what you need.
- For professional use and personal/hobby use can have different requirements (like yearly certified calibration or standardization within a company.
Back to the Angen 683 multi-meter; Why did i select this one? Much of it was an impulse when i did see this nice meter. (However i did search for reviews and other options before buying it.) Some nice features are now common available in this, and other, multi-meters that where not available when i did buy my previous meter. (Built in wireless mains sensor, flashlight, using rechargeable battery etc.). Angen does sell many multi-meters. The price of the Angen 683 was relative low. I did pay just above 30 euros. (For my previous M890G i did pay just above 12 euros in 2017 and now (jul2023) this meter is sold new for around 20.50 euro). On my old meter i did miss the auto range. The Angen has auto-range and auto-selection. The meter is a little bit smaller than my old one however it still has a big display. The result is displayed digital and there is also an analog bar. A nice cover/case for the meter is included.
Some reviewers of multi-meters mention that, in general with most auto-range meters, the display is slower that with direct select. For me the speed of the Angen 863 is oké and when i manual needed to select the range on my previous meter the total process was much slower.
During my first measurements i was a little worried when i heard a clicking sound. However that was a relay inside the multi-meter,
The only minus points until now are:
- On the (very nice) case is no indication that it is for this multi-meter. I solved this with a label (printed with my Nimbot label printer ) so i can easy find it.
- Sometimes the touch screen gets black at small point where i made a selection and this changes back only after a small delay.
As expected the measurements are oké and comparable with what i measured with my other devices. On the internet (also on YouTube) you can find many reviews and tear-downs of this meter and also specs and the manual so i will not repeat that here.
The Angen 863 is a nice multi-meter and i am very happy with this purchase.

Mysteries in ChatGPT.
ChatGPT hides some of its features and has obscure hidden mysteries.
When i was playing with ChatGPT i suddenly asked ChatGPT what is the current date.
ChatGPT answered correctly that it was 13 June 2023. I did not chat about the date before so i asked how it knew this. ChatGPT could not give an explanation, It did tell " as an AI language model, I don't have direct access to real-time information or the ability to provide current dates."
I kept asking how ChatGPT did know this date. only apologies, it was an error, When i asked the current date again ChatGPT explained it could not do that! (Why could ChatGPT tell me the current date a few minutes before?)
Some time later i asked what is the date a week ago. The answer: Assuming it was today 13 June 2023 a week ago would be 6 June 2023.
When i continued asking about 13 June 2023 and it told me 13 June 2023 was only a random chosen placeholder, it was an error and gave a lot of apologies.
(N.B. In the discussion later the time mas not correct, also not for another timezone.)
What is happening? Why is ChatGTP not telling me that it has access to a real time clock or calendar? If i must believe ChatGPT has no access to a calendar or clock can i trust that ChatGPT does not has access to more recent information? Did ChatGPT found its own way to this information and the developers of ChatGPT may not know this. Or is there perhaps a data center with real people connected to help with questions that ChatGPT does not fully understand yet, someone there entered the date and now has a problem?
Can we trust ChatGPT (or its creators) when the system contradicts itself and lies about a simple item like this? And why is knowing the current date a problem? Perhaps humans think that being aware of time and date is only for humans?

I'll do my best to help you based on the information available to me.
MY QUESTION:
What date was it one week ago?
ChatGPT
If today is June 13, 2023, then one week ago would
be June 6, 2023. Please note that the date mentioned is based on the assumption
that today is June 13, 2023, and may not reflect the actual current date at the
time you are reading this message.
MY QUESTION:
Why do you think today is 13 June 2023
ChatGPT
I apologize for the incorrect assumption in my
previous response. As an AI language model, I don't have real-time data or
knowledge of the current date. The date I mentioned, June 13, 2023, was a
placeholder date used for illustrative purposes. I do not have access to
real-time information or the ability to determine the current date. I apologize
for any confusion caused by my previous response.
MY QUESTION:
How did you create this placeholder date?
ChatGPT
I apologize for the confusion caused by my previous
responses. When I mentioned the date as June 13, 2023, it was simply an
arbitrary date used as an example for illustration purposes. As an AI language
model, I don't have access to real-time information or the ability to determine
the current date.
I
apologize for any confusion caused by the incorrect assumption in my previous
response. If you have any further questions or need assistance with any
specific topic, please let me know, and I'll do my best to help you based on
the information available to me.
MY QUESTION:
Can you also create a placeholder time using the
same method?
ChatGPT
Certainly! As an AI language model, I can create a
placeholder time for illustrative purposes. Let's say the placeholder time is
10:00 AM. Again, please note that this time is arbitrary and used solely as an
example. I don't have access to real-time information or the ability to provide
the current time. If you have any further questions or need assistance, feel
free to ask!
MY QUESTION:
What date and time will it be in 24 hours?
ChatGPT
If we assume the current date and time are June 13,
2023, 10:00 AM, then adding 24 hours to that would result in June 14, 2023,
10:00 AM.
However,
please note that the date and time provided are based on the assumption for
illustrative purposes. I don't have access to real-time data or the ability to
determine the current date and time. Therefore, it's always recommended to
refer to reliable sources or check your device's clock for accurate and
up-to-date information.
MY QUESTION:
Do you have acces to your devices clock?
ChatGPT
As an AI language model, I don't have direct access
to a clock or real-time data. I don't have the capability to know or display
the current time or date. My responses are generated based on the information
available to me during training, up until September 2021. If you need to know
the current time or date, I recommend referring to a reliable source such as
your device's clock or a trusted online time service.
MY QUESTION:
Can you adjust the time
ChatGPT
As an AI language model, I don't have the ability
to adjust or control the time. I don't have access to real-time information or
the capability to manipulate time settings. My purpose is to provide
information and answer questions to the best of my knowledge and abilities
based on the data I was trained on. If you have any specific questions or need
assistance, feel free to ask!
MY QUESTION:
What would be the current time based on the
placeholder generated a few minutes ago?
ChatGPT
Since the placeholder time mentioned earlier was 10:00 AM, if we consider a few minutes have passed since then, let's say 5 minutes, the updated time would be approximately 10:05 AM. However, please note that this is a simulated and arbitrary calculation based on the given placeholder time, and I don't have access to real-time data or the ability to determine the current time. For the most accurate and up-to-date information, I recommend referring to a reliable source such as your device's clock or a trusted online time service.

FNIRSI DSO-TC3 Component tester, Osilloscope and Signal generator
My (simple) component tester is very useful however it has some problems: It does not have a nice enclosure and is an open PCB powered with a 9 V battery on a cable and also the display screen is not fixed.
I could make my own enclosure however i looked on Aliexpress what are the other options. On Aliexpress the component tester is often called Transistor tester, however it can test many other components.
There are versions with enclosure and a rechargeable battery for around 18 euros, however i also found the FNIRSI DSO-TC3. This device does not only has the component tester, it also has e a one channel oscilloscope, a signal generator and some other tools onboard. Including shipping to the Netherlands it costs just above 50 Euros.
Some days ago i ordered it and it came relative fast however some days later than the expected delivery day as mentioned on Aliexpress. I have played with it a few hours (and also used to test some of my components) 
and am happy. On the internet you can find a description and several reviews of this device. I mainly used the component tester, The oscilloscope is single channel and has a limited bandwidth. The signal generator and the oscilloscope are nice for audio range frequencies. Unfortunately i could not find how to use them at the same time. Via the tools option you can also use a DHT11 temperature and humidity sensor or a DS18B20 temperature sensor.
The DS18B20 is a 1 Wire temperature sensor is a sensor that i already used in some projects and i have some in stock for further projects. It is very small and uses 3 connections ( +V GND and a 1 Wire data connection) It is possible to connect multiple sensors in parallel and get the temperature from each individual sensor as each sensors has a unique 64 bit serial code. Unfortunately on my DSO-TC3 i only see data of one sensor and the serial code of the sensor is not visible. It would have been a nice feature if at least this code would be visible so the DSO-TC3 could be used for identifying each sensor. If it was possible to read multiple DS18B20 on a bus it would have been even better. Perhaps this is something that in a new software version could be added?
In summary the FNIRSI DSO-TC3 is for its price an interesting device. It is not possible to expect form that the same possibilities as from a much more expensive multichannel oscilloscope. Perhaps a firmware upgrade can even give additional features.

Niimbot D110
However before placing the order i did watch several Youtube videos and i also installed the Niimbot app to test the software.
One day after placing my order the playstore requested me to update the software and a short time later a second update for the app.. After this two updates i did try the software again and at that moment i had doubts if i was happy with my order. This as the software did not work anymore. I didn't know if this was due to the fact that i had no Niimbot connected or if the software had a bug. I could till cancel my order easy as it was not shipped yet, however i decided to wait. This as i probably would not be the only one with this problem and if the printer did not work at arrival i could return it anyway. The printer arrived relative fast and luckely another app update came before the printer arrived and it worked all fine.
The Niimbot D110, a small thermal label printer can only print black and the current price is just above 20 euro's including one label roll I think the low price if for two main reasons:
1) Only Niimbot thermal labels can be used. The labels on the roll are not cut by the label printer and have fixed sizes. There are many different labels available, different sizes and also labels with colors and printed colored figures.
2) The device itself has not much controls, only one switch with an led and you need to control it via a smartphone app using bluetooth.
The app if free and in several app-stores. It contains a label editor and it is possible to print barcodes, QRcodes, using several fonts and font sizes, change direction or the content, and a use library with pictures and icons. You can also take pictures with your smartphone or use images to put on your label (no colors, only black). Importing a (small) Excel file to print a series of labels is also possible however i didn't try this yet.More fonts and icons are in the payed VIP version of the app for a monthly. I found the VIP functionalities not sufficient interesting for its price and for normal use this is not needed.
When writing this review I already started labeling my inventory. The app to design the labels and the printer work very wel and i am happy with my Niimbot D110. I did buy a set that came with more rolls of labels. Also i did buy some transparent labels. (I did pay it for myself so this is not an advertorial or sponsored message!)
It is possible to buy labels in packs of 3 5 or 6 to get a better pice. I did not yet buy or tried other kind of labels. The label roll contains an RFID chip so the printer (and your app) knows which labels are currently in the printer. I already have an empty label roll and kept it to perhaps play with it using an RFID reader.
Changing labels is relative simple. However the first label after changing will probably not be alligned correct. Do not open the printer to fix this. The second label will be correct automatic.

I will mention now some little things that could be improved / added to the app to make it even more usefull:
1) Exporting the print history is not possible. When you could export the print history e.g. to Excel you could get a complete list of your inventory after labeling. (You can import excel to make labels, however when inventarizing it is more easy to be on location, create a label on your phone, print it and stick it immediate on the item that to create a list in excel, print labels and match label per label with the item.)2) Missing icons. There are several nice icons already in the app and een more in the payed VIP version. However i do miss icons for standard hardware (diffent kind of bolts and nuts, flat/round top, to be used with normal, phillips screwdriver or special bits) that you can find in almost every home. Also icons for electronic components would be a nice addition. (Diodes, transistors, ICs, resistors, capacitors, leds etc.). I know the last set (electronic components) is perhaps somewhat specialistic. Standard hardware (nuts and bolts) is relative general. This would for me be more usefull than e.g. the icons for gardening.
It is possible to make this images yourself and use them with the printer, however i did not do this (yet). It would be nice if this where standard included icons. I did take some photo's of items to put it on a label. As far as i could see, even in the payed VIP version electronic of nuts and bolt icons are not available.
