| In the past, radio had something ‘magical’, and that is not all that surprising: you solder a few ‘unsightly’ components together, tie an an...

| Conceded: twilight switches with lots of bells and whistles are available for next to nothing. But isn't it nevertheless much nicer to build...

| Candles are great during this time of the year (these dark days before Christmas), but are also a fire hazard, as we can unfortunately read...

| Many (beginning) electronics enthusiasts shy away from building radio receiver projects – frequencies are too high, capacitor black magic, s...

| Microcontroller systems running 24 hours a day, 365 days a year, can sometimes (rarely) find themselves in a latch-up state. When this happe...

| We already ran into them a few weeks ago: thyristors and triacs – semiconductor switches for DC and AC respectively. As with many other semi...

| This circuit adjusts the gain of (small) input signals such that the amplitude of the output signal is constant over a wide range. The contr...

| In this latest variation of the ‘stairwell lamp circuit’ we will switch the mains voltage. But take note: this can be lethal! If you do not...

| Last week we looked at an energy-efficient version of the stairwell lights switch. Although it works fine in principle, this circuit has the...

| ElektorLabs editors are inundated with reader e-mails expressing praise as well as criticism. One of those criticisms in recent years was th...
