Electronic – Mono jack output to stereo headphones : how to send the mono signal to both sides


I have a 3.5mm jack mono output. I'm plugging standard stereo headphones into this jack, and it plays only on one side. I want the sound to come out on both sides in the headphones (same signal, but in both ears).

How can I cut and wire so that the mono signal goes into both speakers ?

I know there are some adapters on Internet that should do the job, but it's not an option anymore since I have to only 1½ day to finish this…
