The Variable Super Capacitor Charger DIY Kit
Four Voltage Charge Selections
This listing is for a DIY super capacitor charger kit that can have four selectable charge modes, which are talked about below. It is easy to build, and easy to use. An on board microcontroller samples the voltage on the super capacitor, or super capacitor bank being charged thousands of times a second, and acts to limit the voltage via an on board relay. The above video will show you how to work the device once you have completed assembly. There is a 5v regulator that protects the relay and the microcontroller from damage, but the circuit is designed for an input voltage of no more than 9.5v. This kit is designed to charge single super capacitors rated for either 2.5v or 2.7v, or series capacitor banks rated for 5v (2x 2.5v capacitors in series) or 5.4v (2x 2.7v capacitors in parallel). The assembly video below shows you exactly how to go about assembling this kit step-by-step. By using only one on board SELECT button, you can choose between the following charge modes:
Charge Modes:
1) 2.5v - This mode charges your capacitor to roughly 2.43v to 2.45v. This is to ensure that you capacitor is charged to a safe level. This mode is meant for super capacitors that have a maximum voltage rating of 2.5v.
2) 2.7v - This mode charges your capacitor to roughly 2.60v to 2.65v. This is to ensure that you capacitor is charged to a safe level. This mode is meant for super capacitors that have a maximum voltage rating of 2.7v.
3) 5v - This mode charges a series bank of two 2.5v capacitors to a voltage of just under 5v. This is to ensure that your series capacitor bank is charged to a safe level. This mode is meant for two series super capacitors that each have a maximum voltage rating of 2.5v.
4) 5.4v - This mode charges a series bank of two 2.7v capacitors to a voltage of just under 5.35v. This is to ensure that your series capacitor bank is charged to a safe level. This mode is meant for two series super capacitors that each have a maximum voltage rating of 2.7v.
This kit includes:
1) A custom circuit board (PCB) and programmed microcontroller
2) All of the components required to build the kit
3) 24 hour access to the assembly and demonstration videos. (Seen above and below).
NOTE: This kit comes with no hard copy of the instructions. The videos gives you more than enough information to get you up and running. When you purchase this listing, you will receive parts only.
This kit does not include:
1) Super capacitors
2) A power supply
3) Hard copy of instructions.
Requirements:
1) Soldering experience
2) Attention to detail
3) The assembled circuit requires 8v-9.5v to operate. Minimum current consumption is 700mA. The ideal input would be 9v @ 1000mA.
