In case you do not already know this camera is horrible to use in the car. I have one in the third brake light of my vette. The picture is ok at best but within 2 minutes of the sun being on it the screen white washes. I know a couple of other people that have used the same camera with the same results. White wash is a common problem with cameras especially cheap ones. I have a new camera that will not fit in the brake light but should not white wash. I have not had a chance to install it yet.Quote:

Is there any substitution I can make for the 1N414B? It is really hard to find. The only places that have them (that I have found) take bulk orders only. In fact, I can't find the BC549 either. Any ideas?
Just curious as I am about to instal my Carputer and plan to add a Camera in the future. Also, would it be possible to get a pre-programmed pic for those that do not have a PIC programmer?
Xenarc has the auto switch feature built in (on the AV2 line), so you don't need one.Quote:

I ended up ordering a relay with the diode built in. I think the 1N414B is a typo and should actually be a 1N4148. Not only that, the first relay really should be a 12V relay since it is taking a 12V signal to switch it. I am still in the process of building this thing. I have had immense problems but then I don't know much about electronics so I have been having to feel my way through it. I was also told the transistor (Q1) should be changed to a common emitter configuration rather than an emitter follower configuration. I didn't get it working either way but I may have been struggling with other issues.Quote:

Edit: I also replaced the BC549 with a more commonly found one. BC547B.
And I replaced the stabalizing caps with .22uF and .1uF
