Boldport Club: Juice (FAIL)

I started this build a couple of weeks ago and “finished” it today. It is supposed to be a battery replacement kit for use in prototyping if you run out of batteries. It was project #12 in the Boldport Club.

Mine, did not turn out to be a useable device, because I shorted the connections in the USB connector, which I put on last and should have done first. If there’s one complaint about the Boldport Club kits it’s that the instructions are lacking. I messed around with different desoldering techniques to try and correct the problem, but I might have been fighting a losing battle depending on how deep in there the shorted connections were. I figured something was screwy when the LED never lit up. Then when I connected a 9V battery as the power source instead of USB I knew something was really wrong. With a multimeter I was only getting millivolt readings from the board. I felt the battery and it was really hot, so I disconnected to read the battery it was down to less than 9 volts already, when it had started close to 9.5! That’s when I called it quits.

I’m almost positive I thought this kit was something else when I ordered it with credits I had. I can’t see myself using this during a project if it had been a success, so I’m not too disappointed. Even though it was a failure I figured I’d still post the video. Since it was just over five minutes long at 20x speed with all of the footage I didn’t even bother to do any editing. The camera had filled up somewhere during the desoldering complications and I was too frustrated to bother with getting a new SD card. Enjoy! Or not.

Tesla Model 3 Range

A lot of people ask how far I can go in my car and it’s a hard question to answer. There are a lot of factors like season (the batteries are a lot less efficient in cold weather), type of miles, heat/AC use, etc. I decided to keep track of my trip up to Rogers City this weekend. When I got in the car the battery had been charged to an estimated 292 miles of range.

The trip is a total of 156 miles, with 47 of those on the freeway. When I arrived at Mom and Dad’s the battery was down to 101 miles of range.

So that’s 156 actual miles for 191 estimated miles of range. I have the bigger wheels which are supposed to use 10% of the range, so I’d say that’s pretty good efficiency. Below is the energy consumption over the trip.

Battery Leak in TV Remote

Not long ago I pulled out the original TV remote to change some settings. When it wasn’t working, I found a bunch of battery acid had leaked. Good reminder to remove the batteries from items you’re not using.
