Addition of silicon controlled rectifier in triggering circuit of $20 automobile engine-timing strobe gives low-cost general-purpose stroboscope. Modification is completed by wrapping ten turns of No. 18 bare copper wire around flashtube and connecting one end to photoflash transformer T1, with other end unconnected. Can be triggered by 10-microsec 3.v pulse at 5 ma, up to 25 times per second. Flash duration is 100 microsec .-A. C.
