Super Smoke Stopper

Human: *UPDATE* - A fresh enclosure file with labels has been uploaded to prevent anyone from plugging their battery into the shorted terminal. Once again, do not plug a lipo battery into the terminal labeled "NO LIPO - DISCHARGE". This will result in damage to the unit, the battery, and may cause lipo fire. You don't want lipo fire! I bear no responsibility for incorrect use of this unit or its design. How to use: As a Smoke Stopper: 1. Plug a 3s or 4s battery into the terminal labeled "Lipo 3s-4s". The fan will begin running and will run whenever a battery is connected. 2. Ensure that the toggle switch is in the "OFF" position. 3. Plug the lead labeled "DRONE" into the drone. 4. Flip the toggle switch to the "ON" position. This will supply voltage to the drone. If a short is detected, the bulb will illuminate and limit the current of the circuit, hopefully avoiding damage to any of your drone components...ie: NO MAGIC SMOKE! If this happens immediately turn the switch to the "OFF" position to remove voltage from your drone. Locate the short on your model and try again. As a Discharger: Note: I recommend installing a lipo checker set at storage voltage onto the balance lead to avoid over-discharge. The unit has no shut-off built into the circuit or audible alarm. 1. Plug a 3s or 4s lipo battery into the terminal labeled "LIPO 3s-4s". The fan will begin running and will run whenever a battery is connected. 2. Ensure that the toggle switch is in the "OFF" position. 3. Plug the lead labeled "DRONE" into the terminal labeled "NO LIPO - DISCHARGE" 4. Flip the toggle switch to the "ON" position. The bulb will illuminate and the battery will begin discharging at a current rate of about 3a. The bulb will be very bright and also reasonably hot. The cooling system is designed to cool the bulb and carry the heat away from the unit. If discharging multiple batteries in succession, allow the nylon top of the housing to cool in between batteries. Enclosure PLA 20% infill support everywhere Top Nylon - It really does need to be nylon. I used PLA the first time and it got soft around the bulb when discharging. Granted this was before I added the fan but none the less, I recommend using nylon on this component. 100% infill No Supports Foot Ninjaflex 80 percent infill Strain Relief Ninjaflex 80% infill I used 14awg wire on everything except the two wires going from the input XT60 to the buck converter. Those are 20awg. And no, I have no idea why they call it a buck converter....lol. Below is a list of links to all of the parts I used to complete this build. Message me with any questions. Can't wait to see what you guys make!
