Flashing LEDs Electronic Kit– ApogeeKits created the Flashing LED’s electronic kit AMK102B as an entry level introduction to electronic kit building. This kit includes a completely illustrated instructions and circuit schematic. Components are adequately...
This circuit can be used as a low cost SRAM and Microcontroller or Microprocessor Battery Backup. All the diodes are 1N4148, The diodes prevent battery discharge back to power source. D8 gives a one...
Do you have a battery level indicator for a 24V Ni-Mh recharegeable battery source ? Prefer the display as a LED or LCD traveling bar graph. Mail from EY have a look at BVM1...
This is a 9V power supply which will work even on power failure. It uses a rechargeable battery and regulators. A transformer with 15-0-15 AC volts output is required. From my Power Electronic Circuits...
This LED Indicator uses a LM339, a quad comparator. LM339 can work on single or dual supplies, it has a open collector output that can drive 15mA, low power consumption. The circuit is an...
This is a very simple -5V supply using one 555, useful for analog blocks using FET Opamps using low power. This circuit came up when i had to design limited by inventory. It worked...
This circuit is built around LM3647 an Universal Battery Charger, This Circuit is an untested design. It is based on application hints and was provided as an example to the user. This circuit gives...
I was reading about some IC’s from Maxim/ Dallas saying ” Simple battery characterizer” for plotting a charging/ discharging cycles & graphs are available on computer for study I want to plot an extensive...
