Managed to come up with a way of adding a Tripod socket to use with an Archos Camera. This is just a suggestion on a way to get around the problem of the Archos not having a tripod mount built in.
The main ingredient is a knurled 1/4" tripod screw with a tripod 1/4" threaded socket in it. These should be available from a camera shop. If you have a way of attaching a 1/4" nut to a strip of metal then you could get by without this screw/socket.
You will also need a 50mm length of 25mm diameter tubing. I used some pond hose but afterwards discovered that the centre of a roll of 50mm wide insulating tape suits fine. A 1/4" nut and a rubber washer. You will also need a length of metal about 70mm long by about 20mm wide. I was lucky to find a bit which had a ridge at each side. You will need some 50mm wide insulating tape as well.
At one end of the strip of metal I drilled out a 1/4" hole and then using the insulating tape I attached the tuding to the metal strip. Put the screw/socket through the hole with rubber washer attached and tightened it into the 1/4" nut.
I wrapped the Archos Bullet Camera in a 50mm wide strip of heavy duty Velcro and this then slips neatly into the rubber tubing or insulating tape centre tube.
You now have a 1/4" socket to attach to a tripod or ball and socket head.
In the photo below I have mounted it on a suction mount which has a ball and socket head. To the left is a ball and socket head that has a 14" mounting socket in its base. This type of ball and socket head is available from Jessops for about £8. On the right is the centre tubing of a roll of insulating tape. The Velcro covered Archos camera slips neatly into this. I have covered the tubing in Velcro as I have some ideas of other ways of mounting the Archos on my motorbike or helmet.
The combination of using a ball and socket head and the neat fit of the Archos camera in the tubing allows the camera position to be adjusted to get the ideal view.
