[WIP] 18 Volt Drill Master LEGO conversion

18 Volt Drill Master LEGO conversion [WIP] BY Boxerlego Introduction Hi, This is my latest LEGO custom motor project but its not the only one I'm working on I just bought this 18v drill today for the intention of modifying it for LEGO use. My previous drill motor project I only modify an old 18V drill motor to fit with LEGO but this time around I've a new 18V drill motor with a fresh 18 volt battery pack and I'm going to try to fit with LEGO. The nice thing about this is I got that power drill with an 18v battery pack along with charger for a great deal of $16, the original sale price was $35. My first 18v drill motor project had tons of problems to over come and for a long time at first the motor was not even able to be power with LEGO 9V PF system. This was a major problem for me and ultimately I didn't quite know enough on how to drive a DC motors with electronics. So I moved on to my next motor project which was a stepper motor and was more efficient that it could be driven with the LEGO V1 PF system. This was a good step up but it wasn't quite as powerful as the drill motor can be. It didn't take long for me to figure out how to drive a motor with electronics, there are lots of good YouTube videos out there that got me started but ultimately how to properly drive this 18v drill motor with LEGO was still far from perfect. My first motor driver had several mistakes however LEGO was able to still make it work but still those problems needed to be understood and corrected so I can make improvements and make it work better. I will spare all the details here and I will just say that in 2014 I learned tons about how to properly drive motors and more efficiently. Which brings me to my other motor project the upgraded XL motor I'm working on, which is reaching the final stages and that is building the motor driver. This motor driver here for the XL motor MOD is absolutely the best one I made yet. You wont believe what I was able to with this motor driver or maybe you will . I will just say that this motor driver here I made works from the regular 7-9 volts the LEGO Battery box can supply but however the XL motor mod has a switching DC power supply that can step up the 7-9 volts from the battery box to 12 volts for this XL motor mod to work off of. Overall this topic will mainly be about the 18v drill motor LEGO conversion so to start it off I want to show a video time line of some my previous projects with my first drill motor. Video Time Line Think this is either going to work or not please feel free to comment on the matter. I hope everything works out well
