I buy this kit and it works well,but i need to draw in EAGLE an electrical diagram for my school,so i am asking if someone have electrical wireing/diagram?
tnx
The diagram can be found in the manual of this kit…
The diagram shows only with IC1 CD4536 and i dont see any LM 324.
The electrical diagram can be made in EAGLE even if i copied it,but this take time.
Maybe the LM is shown couse im not so good in electronic,but if is,its not in integrate mode.
I also need description if its possible,how this kit works,from when you plugged it in the wall,and to charging acu?
please help me
Can somebody describe working of this charger?
What seperate element is doing in this charger?
Even if the velleman have some kind of discription for it.
Please couse i need this for school.
please answer if anyone know how kit is working because i need for educational reasons…THANKS!!
can anyone tell me the role of BD676 transistor in the circuit ?
I need to know the job of this transistor for educational reasons…
thanks!!
This transistor is the active part of the current source and sources the charge current. Btw: Isn’t the purpose of a school project to show that you are able to figure out how a circuit works by yourself 
I have 2 questions…
How the trimmer is controling the switch off time of the green led?
The working purpose of the VR1 diode…(What job is doing no the circuit?)
VR1 diode is a 2.5V reference diode which is used as a reference for the current source so that an accurate current can be set.
The trimmer adjusts the oscillator freq. of the timer IC.
The work of A1 is to compares the tendency that it in has in the 9 with the tendency in the 10 from the resistances R17-R24, who tendency emanates from the battery .Am I right?
what the job of the others (A2,A3,A4) ?
Can you tell me please the working purpose of A2,A3,A4 ?
anyone?
please…
