USB torche

[IQ12345]

Good Morning Guys,

I’m hoping you can help me out, I’m a woman at the end of my tether.
I have been give the task of redesigning a circuit for a torch. As the
components are slightly too close.. I have attached a copy of the way students solder the copper strip-board . The new board is slightly wider allowing for less errors, we hope. It’s not a rectangle anymore, as you see by the photo.

For some reason the Red LED just stays on like a beacon of failure.
I’m not sure if I need to move the resistor around the switch or move the switch.
Is my capacitor charging? The torch should charge and come on when the push to make is pressed.
I have sent an image of the nearest I have got to a working prototype.
Unfortunately the torch only works when it is in the USB socket, and the light goes off when I push the push to make switch.

I need the torch to come on when the bus to make is pressed and out of the charger.
Rant over!  Hellllllp

You need to add a picture of the other side of your circuit board so we can see your actual connections.

Neither of your pictures shows schematic or any of the component connections. It is literally impossible to tell for sure what may be wrong.

Based on the components, I would guess it it charges the super cap though the diode and then the button connects the cap to the LED. The best guess here, assuming no gross assembly errors, is that you used the wrong pins on the button. The button has two pairs of pins that are internally shorted and the press shorts those pairs.

If you don't have a multimeter (Ohms range) to check which pins of that type switch to use, my experience is that using either of the two pairs of diagonally opposite ones will always work.

My guess would be the switch is rotated 90º, the "original" assembly the switch terminals seem to be in the top/bottom, and in the new wider board they are left/right.

I hate to say it, but the idea of pushing the end of the stripboard into USB sockets is a terrible idea, it's going to ruin them. The thickness is wrong and the kids will snap the internal plastic tab of the socket, which will get very expensive (in IT equipment or whatever).


EDIT: On a more positive note, as the supercap is being charged to 5V, using a (much more efficient) White LED at much lower current would probably give longer run time.
