Power Supply pickup truck (AC and Ryobi Batt)
Description
First thanks for Jpnurro's great design! I borrowed lots of his ideas to make this build. Design highlights * Stacked laptop power supplies to supply 30V+ DC to power regulator * separate body ( handles power input interface) and head (handles power regulator and output interface ) so changing design will not require full re-print * added a space for 40x10 fan to handle heat * spacer between laptop power brick is a separate piece, make it easier to modify design for different sized power bricks. * sized just small enough to fit most 200x200 bed Input Components needed: * DPS3005 Power regulator ( amazon.com/dp/B08L8ZFG5Y ) * laptop power bricks x 2. They should have similar amperage rating, and the sum of voltage should be higher than your desired operating voltage, but lower than 40V. * A properly sized DPDT switch ( I use amazon.com/dp/B07MV52Z9R ) * Battery contact ( ebay.com/itm/132857176268 ) * Figure 8 power socket - I simply reused one of the laptop power brick's socket. * any 40x10 fan Output interface I used: * Banana jack power post ( ebay.com/itm/284296886341 ) * Barrel connector ( amazon.com/dp/B08SLQHXDH ) * XT60 connector ( ebay.com/itm/184047861402 ) Instruction on combining the Power brick voltage: Keep AC side parallel, and connect the DC side ouptut in serial to add up the voltage. How to configure the switch: One side of the DPDT switch is used to switch the AC to the laptop brick The other side of DPDT switch is switching between power brick or battery as power source. Fan - connect a small buck connector to the DC input so you can bring the 30+V down to your fan's voltage. Consider getting a thermal switch to help switch the fan Assemble instruction: Free the power supply from their black skin tight suit First print the bottom, bottom spacer and body, try place the power brick in and plan for the wire routing before starting to combine two power supplies. Consider the switch location during the wire routing, and prepare longer lead for the DC out side so you have a easier time to connect the power regulator Print the head, install the power regulator and the interfaces and wire them to the power regulator's output. Wire up the fan as well. Connect the DC out from the switch to the DC-in on the power regulator and assemble the head to body.
