    Circuit design gone awry (don't know what happen)

    Its just out of habit to put in a voltage regulator in. Since I don't the parts I've only ran in simulation. Does anybody see any possible problem with the circuit (sans the 7805 and the tip31) before I create a parts list?

    Circuit design gone awry (don't know what happen)

    prior to hooking up the diode, I researched the pinout. To confirmed, I ran a continuity check (got 1.8xx), so I hooked it up that way. When the diode was attached to the circuit, the 180mA is way too much for leakage

    Circuit design gone awry (don't know what happen)

    That seems odd, considering the 808 is only taking 454mA, the 555 is at most taking 20mA, and the 7805 is rated up to 1A the key=space just denotes that the space key triggers the push button in multisim Getting back to the design, I ended up reconfiguring the leads so the current source...

    Circuit design gone awry (don't know what happen)

    A couple week ago I deiced to start building a laser pulse circuit. I ended up having a 555 chip in a 'one-shot mode' shoot a trigger into a NPN transistor to power a 1 watt 808nM diode The goal was to A: have a diode deliver 40 J/cm^2 in a pulse B: have the pulse be variable up-to .25 seconds...
