Flashing Red dot finder

[c4xp]

Hello,

I had a problem observing dimmer stars through my standard Skywatcher red dot finder. This is especially true if I want to use 5x telvue powermate.

The minimum setting was too bright,and I had to switch it off and then on again.

I decided to mod the little red dot finder. But I knew I had to design something which will be small enough to fit in the original case (which is pretty small) and run off the standard battery 1.5v.

So I present to you guys my 'little' project.

The pieces are so small that the biggest capacitor I needed to use (220u) had to be downsized , but after some tests it worked out ok.

The movie with the finished product and schematics along with eagle files are on my site c4xp.ro

So what do you think? I can use any comments and suggestions.

this looks like a nice little project and something I might try to do in the future. Thanks for sharing the results.
