Please read - bevore you buy a electronic DIY kit
We have make labels for all DIY kits :
easy to build , middle , hard
Yes DIY is great - if the kit you buy is working on the first try ! If not, it is the worst thing ever. Our electronic kits are well tested and works 100 % if the end user had electronic knowledge and solder experience. If a kit doesn't works - it is in 99,9% not the kit or the electronic/PCB - it is on you !!
While the last years selling DIY kits we get complains that some function or PCB don't works. We get pictures from the soldering works and from the complete build .
In one word - a nightmare. Bad or very bad soldered PCB's, wrong parts,damaged PCB's. Now i can understand that some People only sell kits without giving any support .
Remember - you will mount a complex electronic Kit. It is not a simpel toy. If you solder only ONE part wrong it can be, that the complete machine don't work.
IN CLEAR WORDS
1:) If you don't know how to use a multimeter - you are wrong here ! Learn first how to use it - than come back.
2:) if you don't know what solder iron you had to use - and absolute no solder experience - you are wrong here ! Learn first how to use it - than come back.
3:) if you have no knowledge in electronic parts and if you can't read the part values - printed on the electronic parts - learn it ,
otherwhise you can't build your kit together
4:) if you can't read a schematics , you are 'blind' , and it is impossible for you make a BUG-fix and find your self build in mistakes.
And it is impossible for us to help you. You should know the basics.
5:) Last but not at least . I am not Jesus and i have also no magic eye or a christal ball. A simple question - 'it don't works - what can it be ??',
is not enough to find a mistake. Find a mistake is hard work , find a self build in mistake is harder work. Some of the PCB's are so ' crappy ' soldered that
it is easier to build in one hour a complete new one than fix all mistakes in 2..3 hours .
The points above are absolute basics and a must know. And , you should know ( a little ) how the electronic works in your DIY kit .
Why i tell you this ?
I want to have satisfied customer. We give support for hard and software. And i like it that people contact me because they are happy with the instruments.
Collecting the parts and sort the kits is a lot of work. After this, the most time i spend to give support in questions like this : ' What solder Iron io had to use ', or ,' what is the value of this XXX resistor ',or' how i must use the multi meter', or,' what solder i must use ..... and so on . This makes fun for one time - but not for 100 times.
I can't give People lessons in electronic basic knowledge all over the world.
We are willing to help you , but please , not such questions.
Another example, i get an order and 2 days later i get a complaint - the kit doesn't works. I ask what he had done and i get the answer.'' I am not familiar in electronics - but i have seen on youtube the videos and it looks sooooo easy''.
MAN....... sure - if the DIY people have 30 jears experience in electronics , clear - that looks easy in the video because they know what they do.
Don't think that you can do the same without any knowing.
Fix it's own 'build in mistakes' is hard , very hard - and for a beginner without any knownings mostly impossible.
Important, building a DIY kit is NOT a race ! If you build it fast - you can make mistakes - also fast .
Better is to make it slow. Control each resistor with a Multimeter. If you are unsure about the value of a capacitor /resistor/ IC/, ask google or me or use the following links.
