  1. .. LEDs, resistors and some wire plus good set of different tools and couple of straight hands ;-) LCD consists of PCB, metal frame and liquid crystal glass assembly. Back side of LCD glass is covered with very thin reflective film, ...
  2. .. a 3 V coin cell battery a 100 Ohm resistor (anything close to 100 will work) a momentary or push button switch. thin sheet metal plexiglass tools: hot glue gun metal shears sharpie saw soldering iron Cut out 6 squares of equal size from the ...
  3. .. use glue if needed. Remember also in designing your mount -- the magnetic field from the magnet disc should be away from metal cage bars or other metal will be attracted to these metal parts and will be slowed down ...
  4. .. I made a base in hardwood with two long grooves in which some sheets of polycarbonate could be inserted. I used a metal working mill to cut the grooves but a hand-held wood router should make just as fine cuts. After cutting the ...
  5. .. whenever you want, and prevent others from being able to read it. The signal sent out by a RFID tag is easily blocked by metal. This means that placing the RFID tag inside of a Faraday cage will prevent the information from being read. ...
  6. .. the other lead to the probe is all that is necessary. The user's body forms the other connection through the beeper's metal case. When the beeper is properly adjusted it draws only 10 uA with nothing touching the probe - no power ...
  7. .. NPN transistor, you can drive as many as seven LEDs using a minimal amount of voltage and power from a single NiMH (nickel-metal-hydride) AA cell. The circuit works by creating much higher-voltage pulses than the voltage for powering the ...
  8. .. passive components will enable us to safely monitor the temperature of our coffee cup. Bundle this circuit inside a round metal container (metal helps conduct the cup's heat to the circuit) and you have a Smart Coaster. TIME: 3 hours COST: ...
  9. .. concepts. The implementation is easy. First, a few words about IC package heatsink electrical connections. Note that the metal thermal tab of IC1 is NOT connected to the thermal tab of IC2. And NEITHER is connected to the supply GND ...
  10. .. their iPods easy to open lately, and unfortunately we don't expect things to change with this iPod. We begin by inserting a metal spudger into a crevice between the rear cover and the rest of the shuffle. Inserting the metal spudger creates ...
