Hi everyone !
I just just finish to solder all the component but I have a problem.
When it says :
"Now it is time to test the boost converter.
Clear off the desk and make sure there are no stray wires hanging around. Plug in the board and be careful not to touch the right hand side of the PCB. If you need to hold the PCB, hold it by the left hand side near the DC jack. This way you will not risk touching the boost converter. Use a nonconducive vise if necessary.
Set up your multimeter to measure around 60VDC. Touch the black (negative) lead to the ground tab of the 7805 and the red (positive) lead to the striped end of the diode. You should measure around 60VDC. It may be as low as 40V but not lower. It should not be higher than 70V.
If the voltage is higher than 75V, check the wall-power supply. You may need to use one that is lower voltage and/or current rating. Do not continue if the voltage is higher than 75VDC"
I have a voltage of only 9.7VDC what did I do wrong ? Why the voltage is so low ?
Otherwise everything works the tube lights but very low.
I hope somone can help me and sorry form my english I am from switzerland.
