Ryobi Power Deck (Battery Adapter, Power Supply)

UPDATED SEPT 28, 2019: I introduced a brand-new electrical contact frame design based on Keystone 209 hardware. See below for more details. _____________________________________________________ What is the Ryobi Power Deck? It's an exact, portable, rechargeable, DC power supply for your projects. This solution converts a readily available Ryobi battery (~20Volts fully charged) down to a lower voltage (0.00-18.00V), and current (0.000-5.000A), which are chosen by the user based on the application. The power supply is very precise and has high resolution (can set values to 1/100ths of a volt). The shell fits perfectly in your left hand while adjusting power settings with your right. It's well-balanced in the hand with the Ryobi battery in it. The shell fits snugly on the Ryobi battery and locks into place. The banana plug jacks are recessed for a cleaner design. So, why would you need this as part of your electronics tool kit? It's an accurate power supply with a good range of Voltage and Amperage. You can use this solution to power ESP8266 IOT boards. Use it to power led strings, or laser modules. These sensitive electronic devices can be easily damaged if the supplied power is not correct. It can also be used to recharge 18650 batteries. I've even used it to run a DC to AC inverter (very lightly loaded) to run a small water pump in a remote area with no grid 120V power source. You can also use it to revive Eneloop rechargeable batteries.
