- .. is truly a simple digital thermo meter, a beginner’s project, but having sufficient accuracy. The brain of this circuit is PIC16F877A ; a ...Nov 20, 2008
- .. should be in darkness, though the circuit seems to work okay with the neon bulb illuminated. The only effect is that the meter ‘autozero’ has a much shorter time constant when the neon bulb is illuminated. The meter can be of ...Feb 2, 2009
- .. 'Freq' preset in the simple timebase should be adjusted until this is the case (if you are lucky enough to own a frequency meter, then adjust for a frequency of 554.83 Hz). Once set, the second hand can be removed again, and the clock ...Feb 12, 2009
- .. dining table, and cleans up in like 2 min when friends come over. (It's the alarm-time-setting part of what's going to be a meter-clock.) I bring the setup to work sometimes when I feel like playing hooky. Add a small bag of goodies (some ...Mar 28, 2009
