Yes- all you need is a paper clip. On the edge of the flash where it mounts to the camera there's a round pin at the top inside a collar- this is the activation switch- and a lug at the bottom with two pins; this is the firing circuit. Push the switch in with the clip and it should turn the flash on and start it charging. Now bend the paper clip into a "U" shape. Once the light comes on, touch each of the contacts on the bottom lug with the bent pin to complete the circiut. Hey presto.
