Electronic Fuse Employs A Relay

Posted by Unknown Tuesday, April 30, 2013 0 comments
while many power supplies can be set to limit their output current to a defined level, to protect the circuit they are powering, no such protection is available if you are powering a circuit from a battery. If a fault develops, the circuit can blow before you have a chance to disconnect it. Of course, you can fit a fuse in series with the supply line to the circuit under test but it will blow if a fault develops. Or perhaps it won’t blow sufficiently quickly to protect the circuit. And repeatedly...

Simple Purpose Alarm

Posted by Unknown Sunday, April 21, 2013 0 comments
The alarm may be used for a variety of applications, such as frost monitor, room temperature monitor, and so on. In the quiescent state, the circuit draws a current of only a few microamperes, so that, in theory at least, a 9 V dry battery (PP3, 6AM6, MN1604, 6LR61) should last for up to ten years. Such a tiny current is not possible when ICs are used, and the circuit is therefore a discrete design. Every four seconds a measuring bridge, which actuates a Schmitt trigger, is switched on for...

Soldering Iron Tip Preserver

Posted by Unknown 0 comments
Although 60/40 solder softens at about 200°C, the tip temperature of a soldering iron must be at about three70°C. This is important to make a just right fast joint, without the danger of overheating refined parts because the iron needs to be saved on the joint for too long. Unfortunately, at this temperature, the tip oxidises swiftly and needs constant cleaning. Thats the place this circuit can help - it preserves the soldering tip to simplest beneath 200°C while the iron is at leisure. Oxidisation...

Digital Bike Tachometer SP

Posted by Unknown Saturday, April 13, 2013 0 comments
This digital SP tachometer for bikes uses 2 reed switches to urge the speed data of the bicycle. The reed switches are put in close to the rim of the wheel where permanent magnets pass by. The permanent magnets are connected to the wheelspokes and activate the reed switches everytime they pass by it.

Long Interval Pulse Generator

Posted by Unknown 0 comments
A rectangular-wave pulse generator with an extremely long period can be built using only two components: a National Semiconductor LM3710 supervisor IC and a 100-nF capacitor to eliminate noise spikes. This circuit utilises the watchdog and reset timers in the LM3710. The watchdog timer is reset when an edge appears on the WDI input (pin 4). If WDI is continuously held at ground level, there are not any edges and the watchdog times out. After an interval TB, it triggers a reset pulse with...

Contrast Control for LCDs

Posted by Unknown 0 comments
The adjustment control for the contrast of an LC-Display is typically a 10-k potentiometer. This works fine, provided that the power supply voltage is constant. If this is not the case (for example, with a battery power supply) then the potentiometer has to be repeatedly adjusted. Very awkward, in other words. The circuit described here offers a solution for this problem. The aforementioned potentiometer is intended to maintain a constant current from the contrast connection (usually...
