Kickback! and the bathroom vanity cabinet

I started planing some wood down to ¾” thickness for my bathroom vanity cabinet:   As I was ripping one pice to width a small sliver came loose; there was a crack in the end of the wood, and as soon as it was free it caused some HEFTY kick back. Luckily I never have my body directly behind the wood while ripping, and the SawStop’s awesome splitter prevented it from actually kicking back. It pushed back in my hand about 5 inches. I am really happy with the SawStop.      I’m starting to get some of the pieces... [read more]


Bug down! Charger broken (again – 3rd time)

Sadly, the electric VW bug will be taking some time off the road. Last time it was the transmission, and this time it is the Manzanita Micro PFC-30 charger. I didn’t even get a 1000 miles before another problem came up. I was really hoping to hit 40,000 miles and it is nearly there hovering a bit over 39,700 miles.  Last Sunday I was charging the car and pulling about 27 amps. The charger should be able to pull 30, but quickly goes into a limit mode due to temperature. This happens no matter what the temperature is, and is... [read more]


chargepoint energy stats for my bug

Since July of 2011 I’ve been using chargepoint for charging at free charging stations, and at work. Prior to my work getting J1772 stations, I would use a dryer plug outlet that was provided for EVs. Here is a screen shot of the stats for my use: 10,673.912 kWh used in about 4 years. Mostly with the bug, but some with another EV (Jan/Feb ’15). This also doesn’t include other J1772 stations I’ve used that aren’t charge point (i.e.: the free stations downtown Santa Cruz), and it doesn’t include charging at home.  The large gap from August to January was...

Plug Bug: You are only as strong as your weakest cell

I had known for quite some time that I had a weak cell in my battery pack. My electric bug’s battery consists of 48 lithium iron phosphate cells. I use the eLithion battery management system with a custom display I fabricated along with some custom ardiuno code to show cell info from the CAN bus. I would routinely see one cell (number 9) sag heavily under load.  One day I left work work (a 20 mile drive) with my pack at about 50% charged. At about five miles from work my low battery warning buzzer went off telling me that... [read more]
