Parts: 1. MPF-102 (N-channel FET and our preferred transistor) or NTE-326 Transistor 2. 1 Meg Reistor 3. LED (we like "Super Green") 4. 9V Battery Terminals 5. 9V ...
The circuit diagram is here. When soldering, there is no real need for extra wires depending on the type 9V terminal you are using. All of the electronics ...

Tools: 1. Soldering Iron 2. Wire clip holding helper (not necessary but helpful)
Is a primer safe with positive. No bullet. Checking electric idea
<p>Had some extra space developing a PCB and use it for a new Static Detector PCB. Here are a couple of pictures...</p>
<p>Are you sure in your robot video above that your static detector is not dimming because you are bringing it closer to the floor which is most likely at a ground potential??</p>
<p>Built mine on a PCB super glued to the 9V battery connector using the <br>MPF102. Works very well. Burnt out my first ultra bright red LED so I <br>added a 220ohm resistor in series with the second LED and so far, so good...</p>
