Transformer in this package create a lot of manufacturers. This question appears to be off-topic. Component view Printed circuit boards Board is designed single-sided. We can also use 2 pin connectors for LED connecting. Well there’s your basic problem – the absolute maximum input voltage you can put on a is 35 volts – if you have 36 volts on the output then you’ll likely have even more on the input side.

You could build something similar if you don’t need high performance. Next are small filter capacitors and also signaling LEDs connected via resistors. Connect the positive of the two leads to your ground, and the negative will be your V supply. PDF format Eagle6 format. Something like this should suffice for a quick setup.


We must also check allowed voltage of capacitors. It doesn’t matter on the assembling order.

I am Basically building the power supply scene here kerrywong. I ordered it at small local company Kohout Spoj. Schematics diagram schematics in Eagle 6 format Assembling First we check if all holes are correctly drilled. When The Regulator is in the circuit it just passes the original voltage right though so on the output pin i get around 36 volts.

79L12 TO-92 voltage regulator -12V 0.1A

So, given the above, there is a strong case for assuming the regulator is datashset and therefore reusable. If voltage on the big capacitors will be under Your transformer must be center tapped 24V type, commonly denoted as 12,0, Circuit description Circuit has on the primary side only fuse. I also posted the link to the website in my first comment.

Your problem solved without need to have the We assemble parts from a smaller to bigger.

Series diodes drops 0. Connect emitter to the V output. Almost all components are usually available. The diode droppers in your circuit, at low currents will not drop the supply voltage below 35 volts.

Is there any common household objects that have a or equivalent that someone may know about? Next are positive and negative voltage regulators 78L12 and 79L12 with decoupling capacitors C3 to C6 close to regulators. The thing about both the and is that the pin out is different as you are aware but there is a strong possibility that the you connected incorrectly is not actually damaged. Now connect them in series and take the center tap as your common ground.


Next we continue with connectors, transformer and big capacitors. If this is just for a short demo, then you may be able to use a few batteries.

The 79L series are mA regulators in TO packages. Olin Lathrop k 30 I have a few 2n transistors laying around would that work?

We begin with resistors, small capacitors, leds, regulators, fuses and rectifier. At uA load, you won’t need a heatsink.
