I found this little Pumpkin for Halloween here in the U.S. big thing around where I live. However, in the parts list the photo transistor is not available to me Under NTE from the local distributor.
Any suggestions on a comparable in NTE ?
Here's the list :
A phototransistor (we use type LTR-3208E)
2N3904 (or similar) transistor, QTY 2.
5k ohm resistor
Yellow or red LEDs, QTY 2. (We used 10 mm diffused yellow LEDs)
50 ohm resistors (one for each LED)
Battery holder with 2 AA-size alkaline batteries
This is the site : https://www.evilmadscientist.com/article.php/darkpumpkin
And schematic.
I know I should have chosen another place to post it. However, maybe there might be someone else interested who might miss it.
I think it's a cool little Pumpkin.
