hello,
I'm trying to increase the voltage from a 9volt battery by connecting it to a 555 timer then through a audio transformer.
The problem is the voltage does not increase.
The 555 timer works, using 619 Kohm resistors for R1 and R2 and 0.1uf capacitor i get 85 ms on and 42 ms off.
The voltage goes up and down on pin 3. The transformer i'm using is shown on the website below,
http://www.maplin.co.uk/Module.aspx?ModuleNo=3709&C=SEO
it is the LT700
primary 1.2kΩCT
secondary 3.2Ω
I have reversed the transformer, so the output of the 555 timer is connected to the secondary. This should increase the voltage on the primary.
The reason i'm using this transformer is because it is small.And the reason why i'm doing this is becasue i want to see it working.
When i connect the volt meter to the any of the three wires that come out of the transformer on the primary, i get nothing.
Can anybody tell me what i'm doing wrong.
