| Nowadays, with the advent of SMD (surface mountdesign), it is possible to construct tiny circuits. In the case of crystal oscillators th...
| The stepper presented here makes use of nine positions of a 12-position rotary swtch. It is, of course, possible to add the omitted steps...
| The simplest solar-cell supply system consists of three parts: a diode, a solar-cell panel, and a rechargeable battery. The diode prevent...
| Although there are a number of ICs available that convert frequency to voltage, this can also be done with discrete components as shown...
| Timer chip ICM7250 from Maxim enables a very simple timer to be designed. The IC has eight programmable inputs for connectlng to, say, tw...
| The governor described in this article is intended primarily for small 12 V motors that draw a current of not more than 2 A. Many governo...
| If you ever need to derive a 5 V line from, say, a 15-25 V supply, National Semiconductors LM1575 and LM2575 are ideal. These switched 5-...
| Most debounce circuits shorten or lengthen the time a switch is pressed to obviate interference pulses caused by switch bounce. The pres...
| Some methods used in electronics are based on models that cannot, in fact, be the case. For example, currents flow continuously and yet co...
