Very Good Value made all five kits up but with my own selection of leds 2 of ea red, yellow, green, blue and white. Also changed R1 to 10K ( from 47K ) and C2 to 4.7uF ( from 1uF ) plus added a switch and a 3 x AAA cell battery carrier.
Teşekkür ederim kullanacağım - 謝謝你我會用 - Thank you I will use
Thanks very much the goods arrived full without shortage on 6-3-2018
Great price for a simple circuit; easier than gathering the parts and trying to make perf board work. The only problem I see with this is it has a CMOS IC in a regular zip lock bag; this kit really should be in an anti-static bag like the other kits I've gotten.
Nice little LED flash DIY kit.
The package arrived on time. Unfortunately, the 50 pieces with 6 LEDs do not work. A unit can not be used. It is therefore not vook off star if we agree;)
