Dc Voltage Controller Box

thingiverse

This is a design to help regulate voltage use which consists of a switch for the main power source and a potentiometer to adjust the output voltage. This can be used as a static designed attached to the side of your work bench giving you full voltage control from a DC socket.My use caseDesigned to allow me to control a hand held motor (my next project) for cutting / sanding 3D parts.Example https://youtube.com/shorts/Si6LcVitMbY?feature=shareParts:1 x LED light1 x 390 Ohm resistor1 x 10K Potentiometer: https://www.amazon.co.uk/dp/B07WQG1RNZ2 x Dc Power connectors: https://www.amazon.co.uk/dp/B0BY161TY71 x Toggle Switch: https://www.amazon.co.uk/dp/B07J4KB38W1 x MOSFET transistor: https://www.amazon.co.uk/dp/B096FH2FJS1 x 4cm x 6cm Prototype board: (Product unavailable but something similar) https://www.amazon.co.uk/dp/B074X2GDH2Materials used:18 AWG Solid Wire: https://www.amazon.co.uk/dp/B085TP7G5B4 x M4 Thread Inserts + bolts4 x M2.5 Thread inserts + bolts (NOTE: I already have 4 screws / bolts and the following link will not provide the necessary bolts needed).Bolts: https://www.amazon.co.uk/dp/B09BG4Z2V1Thread inserts: https://www.amazon.co.uk/dp/B09PBJHMNDPrepping the Box:Print containerI am still learning so I am not quite sure if supports are needed or not but I just did them any ways.Print container side panelNo supports requiredMay need some sanding just for it to fit smoothly into the containerInsert the four M4 insertable threads.Insert the M2.5 insertable threadsI never managed to print so the holes aligned up so I just used one of the four threads instead.Prepping the electronics:For soldering, follow the below diagramKey notes:Circles represent the component cables slotting into the boardGreen: SwitchDark Blue: MOSFET TransistorLight Blue: PotentiometerGold: ResistorYellow: LEDRed: Positive wiresBlack: Negative wiresWhite: The underside solder to connect two spots.Upgrade ideas:Digital display to view the VoltageNext steps:Building a small hand tool (similar to a dremel tool) Enjoy!I am aware that I might be missing some information here and there so please feel free to comment if you have any questions or ideas.
