    An interesting kit based in the old ICL7107 chip...assembling it will bring some rememberings back.

    It is a nice instrument. Shows both positive and negative current flow (which not many ammeters do), it is accurate (more than what the average amateur/hobbyist needs), the assembly instructions are good, and its price is more than nice. Its only drawback is that it needs a 5 Volt power supply, which is not easy to get from batteries. So, I decided to put it in a box, together with a regulated power supply (9 Volts battery + 7805 voltage regulator) and a switch. There are three ways to feed the current

    All listed elements were there, instructions are good enough and final product is working fine (same value as my ammeter). You need a magnifying glass in order to distinguish between the simple diodes and the voltage regulator diode.

    Il kit è ben progettato e non presenta particolari criticità. Il circuito assorbe 42mA ed il suo consumo è costante. Ottimo per varie applicazioni che prevedono un assorbimento massimo da monitorare di 2A. Consigliato, anche come semplice esercizio di saldatura.

    I had a lot of fun building this meter and it works very well. It will even indicate polarity of the current flow. By changing the shunt resistor and moving the selectiale solder bridge for the decimal point you can also make it a 0 to 20 Amp or a 0 to 200 Amp meter. The display can be calibrated if you have a good reference. I built mine into a case and now I have a nice auxiliary 2000 mA bench meter.

    Purchased 3. Mounted and calibrated (100mV). They look very accurate (see photos). I'm reasonably happy.
