Using an exacto knife, I cut out my pumpkin face stencil. I securely taped the stencil on the plastic cup and using my paint brush dabbed on paint. Allow paint to dry for 5-10 minutes and then peel off your stencil (which can be reusable). Another alternative if you don't have ...
You need to disconnect that Pin from the ground plane (e.g. with an Exacto knife) and connect GPIO 24 to it. The following images illustrate the case for IDC Pin 4. If the direct connection does not work, you need to send it through a free level converter of the Adafruit HAT/Bonnet...
you have to figure out which is the input of the E-Line on your matrix (they seem to be either on Pin 4 or Pin 8 of the IDC connector). You need to disconnect that Pin from the ground plane (e.g. with an Exacto knife) and connect GPIO 24 to it. The following images illustrate...
I built my mask from 3/16” foam board from Michael’s or Hobby Lobby - light weight and easy to cut with an exacto knife. Also more resistant to moisture and dew than standard cardboard. Since many of the mask shapes are doubly symmetric you only need to make a master cutting or tr...
Form each digit in the polystyrene using a exacto knife (very hard) or a Hot Wire Cutter. You can see how I made mine in the pictures. If you don't have a guitar string you can use just about any thin STEEL wire. In order to power the Hot Wire Cutter I used the 12v LED power...

it's the same SIM card that is in every phone today except that the remaining board around the chip has been removed. When I got my iPhone 4 I literaly took an exacto knife and ruller and made my own Micro SIM from a Mini SIM. I then use an adapter so I could use it...
This creates many novel educational activities for students to explore IR radiation in the classroom and beyond. I describe how to modify an inexpensive computer webcam and some uses for it below. Hardware: The...
