I landed [after] following other aircraft in the pattern to runway 01. I observed one aircraft in the pattern for 19 while having lunch and observed this aircraft taxi to parking. I observed another airplane taxi in the direction of the departure end of 19. I made a poor decision to depart as planned on 01. While completing my run up checks I heard a pilot report he was taking runway 19 for departure [6;000 foot runway]. After observing this aircraft depart I called 'Cessna XXXX taking runway 01 for a straight out departure'. There was no reply. Upon entering the runway and beginning takeoff roll I observed another aircraft taking off on 19 towards me. I continued to accelerate; lifted off and immediately maneuvered to my right off the east side of 01. The other pilot executed a similar maneuver to his right; we passed approximately 100 ft AGL separated by little more than the runway width.Someone (I believe an FBO employee on the ground) said on the radio 'That was close gentlemen' I replied that I had made departure call and had observed the only other aircraft that had announced its presence depart prior to entering the runway. Some minutes later a pilot asked for a radio check; he was loud and clear. I asked if he was the second pilot involved which he confirmed and stated he had a radio issue and was not transmitting although he indicated he had received our transmissions. I did not inquire where he was when or if he heard my departure call.I feel both pilots share equal responsibility for this close call. I should have changed my departure plan and followed the flow of traffic. The other pilot should have ensured he was transmitting and responded differently if he did in fact hear my departure call.
C172 pilot reported a NMAC during takeoff with an aircraft taking off in the opposite direction. Evasive action was taken by both pilots after lift off.
