@@dudicoco definitely will cost less than that and I don't know about which soldering station premade you are mentioning. Maybe that one don't have the option to can use more options on iron tips

@@Jacob-vx4zw hi there when you get the soldering iron handle please make sure you check the connection diagram of the wires from the connector to the iron tip because you need to modify some pin orientation. About the wires I used for the mains AC voltage stripped a pc power cord and used and from the power supply to controller board used wires from an old pc power supply.

@@Johadart I used some plastic spacers harvested from some old computers to fit the power supply. My son name is Anthony and yea is growing fast already 2 years old soon I need to send him to school. I'm happy to heard that you may want to build one similar soldering station and stay tuned because I learn how to calibrate it and use the settings to make it work properly so I will have an other video about this soon.

@@SymbolTech21 cool buddy can’t wait to see..

@@Johadart hi Joe, if you will use the same soldering handle please check the wires connection from the tip to the connector as per connection diagram from the control board listing link to make sure it's ok because for mine I needed to make some modifications swap some pins around on the connector

@@SymbolTech21 ​​⁠ok I will do Tony, thankyou for letting me know this.. 🤙🏼🇦🇺

@@Johadart also make attention when ordering the soldering handle to have the same connector as the controller board have because you can chose between 2 types of connector

@@christopherward5065 I test with the pots up because I changed capacitors on that circuit path to see if tone control works good

It's cheap to build and it's really powerful. Definitely much better than my old t12 station

@@DeathbyKillerBong I will think about it. First I will see to install the power supply and then I will work out the space I will still have available inside

@@qaisarawan93 the problem is that I don't have high frequency transformers to do this project. Then from solar panels first you need to connect to a solar battery charger and then from the battery to inverter

@@kostis2849 I have but is long and no space on the case which I will use it for the soldering iron station project that will be my next video

@@kostis2849 I was thinking the same to build the preamp with headphones amp inside but I need to see if I can manage to fit the PCB's inside and the power supply to

@@Irilia_neko the multimeter test probes are silicone

@@SymbolTech21 i can warranty they aren't, for one too cheap to be in silicone, and secondarily they are too hard to be silicone 😉 you can always try with your solder iron PVC can't handle more than 80 C 😉

@@Irilia_neko I have more silicone wires different gauges and the multimeter test leads are silicone. The other white and the standard they come with the multimeter are not

Will be not so good to do that because if are not exactly the same voltage maybe sparks can happen. But can do other things to be more powerful is to put in parallel maybe 2 power transistors and that will double the power handling only that definitely will need bigger heatsink as well to dissipate the heat faster in special when using low voltage and high current

Definitely if you listen straight to it not through recording process and then UA-cam, there is improvement.

I was surprised as well of that big packing and inside just 2 items

Yes I get some nice stuff

And which application will be used?

@@SymbolTech21 there's not much use of it (e.g., testing rechargeable batteries or as an amplifier for a signal generator or an an AC source) and it is not easy to be made, but that's why making it would be fun and great for bragging too, as very few people has one.

@@bsimic29 I have 4 signal function generators then I will keep in mind for this project suggestion and maybe in the future I will build one.

Yes I did that and how you can see in this video is the closer to accurate possible I come by adjusting those 2 trimpots

Hi by the way I just got a new voltmeter ammeter and I installed and now the reading measurements are more accurate.

First you need to open the center tap and make it dual 49v and the voltage regulator kits I use on this project they can run max with 24v transformer. So for your transformer if you open the center tap to be dual definitely can go to this project ua-cam.com/video/yaxJYI5ejf0/v-deo.htmlsi=mCi9S1oJ_DQQ7NDY

@@SymbolTech21 thanks for the reply. I tested the transformer. It has a 230v primary (UK mains) and +49v 0v -49v outputs. I'll look at the links. Thanks.

@@deanedgx if you can open the center tap then you will have a dual 49v

Yes because I installed on Arduino nano the Uno bootloader

Can be easy and cheap to build an amplifier

For vibration switch need to modify the code to add kind of timer because vibration switch it's not all the time open contact or close contact it's depends the position of the handle

Definitely will be because already I'm working on building a dual rail linear bench power supply to have it handy on testing the preamplifiers! And soon will be the video about the power supply soon

Yes I really like the chassis

Nope I will not recommend this amplifier kit

@@SymbolTech21 Thank you. I canceled my Aliexpress order. What amplifier board is good? Supply +-65V (substitute for STK4248)

@@brankozivkovic6555 l12 it's a good amp only that power supply is dual 50 v

L12 definitely

You mean the one with the capacitor?

@@SymbolTech21 yes

@@iulianvasile2870 so the capacitor is connected between 0V or gnd to earth

@@iulianvasile2870 because the chassis is earthed and the amplifier 0v or ground is isolated from the chassis and between the chassis and ground is the capacitor

@@SymbolTech21 thanks a lot for info. very useful. i play some times with different audio kits from China and is good to know from a skilled guy like you . i am not an electronist , just a self-learning

There is no need for this amplifier to have a preamp because the input sensitivity for max power it's only 250mv

@@SymbolTech21 ah ok, thank you 👍

Unfortunately I'm not selling. Because was a project for a friend !

You mean those devices which connects to radio via FM and you connect the mobile via Bluetooth?

@@SymbolTech21 correct

@@DeadKoby the quality of the he sound was losing via FM some of them the transmission was not stereo neither

Neither because I ordered an RC airplane and they sent me a full size f22 and customs hold it

I just tested those connections and are inputs so I don't know how can be streamed if it's an input

When all the capacitors are dry I don't know which sound signature you have. Then you can ask any audiophile if ceramic capacitors are good on audio gear. And please let me know them answers.

@@SymbolTech21 I don't believe capacitors go bad in 50 years at least.I have NAD1155 from the 70's and still sounds crystal clear and more dynamic than anything i have tried!Film capacitors sound bright for sure!I am not a fan of recaping a unit unless it is broken...The sound signature is achieved mainly in result of the material of the components in my opinion.Recaping can change the sound,but that does not necessary mean it will become better.In most cases the caracter of the sound is changed for the worst.

Yes all parts

To work as a ups need some additional electronic parts AC voltage detection and battery charger

Thanks, what's wrong with AliExpress canada?

I already checked and is not that the problem

I think it's not that the issue because it's more RMS from 5khz to 15khz then start going down

@@SymbolTech21 This is very strange indeed. Maybe ringing?

@@kostis2849 I need to check the function signal generator because I may think that comes actually from it

I like them to

I used a tool like this one to bend the leads www.ebay.co.uk/itm/322821956499?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=biMeahOQQKW&sssrc=4429486&ssuid=e2bvqqopq7c&var=&widget_ver=artemis&media=COPY
