| A continuity tester is a useful bit of kit for any electronics enthusiast but many of the off-the-shelf models you can buy suffer from one s...
| This circuit can measure the capacity of individual cells as well as battery packs with an open circuit voltage of up to 35 V. The only requ...
| There are a number of programs written for PCs and other computers that allow the user to design and debug fuzzy systems. Figure 1 shows a s...
| In previous articles in this series we have described an A/D converter based on a counter. A ‘real’ A/D converter, however, converts a volta...
| In the previous instalment we measured capacitances and resistances. You may have wondered if this was all worth the effort, when accurate a...
| So far in this series we have used the PC only with digital signals: switching, monitoring and counting. Now we turn to the analogue domain:...
| In many circuits the switching action is performed by a relay, which in turn activates an external load. This part of the circuit is rarely...
| The brief: design a tiny AF amplifier powered by a single 1.5 V cell, yet capable of driving an 8 ? loudspeaker. How can these requirements...
| So far we have studied the characteristics of the RS-232 outputs in detail. Now it is the turn of the inputs. The standard demands that an i...
