DIY knowledge

Please read - bevore you buy a electronic DIY kit 

We have make labels  for all DIY kits :

 

easy to build , middle , hard

 

 

• easy - you have build some easy  circuts  with success  and now you want more.
• middle - you have success with  a lot of your builds - now you want to grow up in electronics. You can also read and understand schematics. You can work with a multi meter
• hard   -  you are a (semi) or professional in electronics, you have a lot of experience in electronics and solder works,You can work with measuring Instruments. 

 

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.

 

Here are some helpfull links
