How to recycle in Barcelona

Barcelona has many curbside recycling bins that are color coded.


The blue bins take paper, magazines & cardboard (folding boxes), but NOT the plasticized cardboard juice and milk boxes. (Which go into the yellow plastic bins instead. Also, no tinfoil, because it’s metal, not paper!)


The yellow bins take all types of plastic, including plasticized juice and milk boxes, but don’t throw in plastic toys or DVD/CD-ROM’s. They also take metal cans (I’m not sure if this is just aluminum cans, or all types of metal cans.)


The green bins take all types of glass, but no metal lids or lightbulbs, or ceramics.

The brown bins are for organic remains (think compost), and all of your regular trash goes into the light gray bins. Currently very few people in Barcelona actually recycle, and most just throw all of their trash together into the gray bins.

How to open a 2013 Nissan Leaf battery pack and remove the modules


I have opened my 2013 Nissan Leaf battery pack and removed the modules. The tools needed are:

  • 500 volt class 0 (or better) electrically insulated gloves
  • One or two full rolls of black electrical tape, for covering your tools and the terminals of the modules when you remove them.
  • Regular leather gloves
  • Side clippers and needle nose pliers for removing wire tiedowns
  • 1-1/2″ putty knife or chisel and hammer. (or preferably an air chisel)
  • 10 mm wrench (preferably a socket with ratchet)
  • 13 mm deep socket
  • 16 mm wrench and hammer (or impact driver w/ 16mm socket)
  • small flat bladed screwdriver for prying clips
  • # 1 Phillips screwdriver for removing screws on the sense terminal of the modules

How to drop a Nissan Leaf battery pack (without an auto lift)


NOTE: The battery pack has 400 volts inside of it. Be sure you know what you are doing and have the proper protective equipment, as it can kill you! It also weights 600lbs, so it can crush you!

I needed to remove the battery pack from my Salvage Nissan Leaf. The 2013-Nissan-LEAF-DG.pdf (Disassembly Guide) I found on the Nissan website has good instructions, but they assume you have an auto-lift (and custom battery moving system).

I didn’t want to purchase an auto lift, so I did it with the following tools on my concrete driveway.

  • Class 0 – 500 volt electrically insulating gloves. Necessary when pulling the service disconnect, and the high voltage cables leading from the battery to the motor and interior cabin heater.
  • Continue reading

It’s Alive!

I was able to move the leaf under it’s own power (using two of it’s own wheels as well…) I titled the video “Drifting the rear end” because I want to see how many racing enthusiasts I can troll. This is probably the last time this Leaf will move under it’s own power, as the next step is to drop the high voltage battery pack.

Booting up a Nissan Leaf

Hojas, the wrecked 2013 Nissan Leaf that I purchased at an auto auction site was delivered to my house, and appeared completely dead. The first thing I did was to check the 12 volt “accessory” battery, and found that it had drained down to 1.5 volts. I think this was because in the collision one of the rear doors was knocked ajar, and the interior lights were illuminated because of that, but it could have also been due to the 2-3 months it had been sitting in the auction yard, or perhaps somebody initiated the emergency shutdown procedure.


After charging the 12 volt battery back up, I was able to put it into “accessory” and “on” mode, Continue reading

How to purchase a Leaf Battery Pack (and surrounding car)


This is Hoja, a new (to me) 2013 Nissan Leaf. Hoja was rear-ended sometime around December or January, and was “totaled” by his insurance company, The Travelers Indemnity Company. They used Copart, an auto-auction company to sell the remains with a salvage title.

I purchased Hoja just to obtain the LiIon modules in the battery pack, and was happy to find that the dash console reports that the battery has the full 12 bars of capacity, even though he has almost 19K miles under his tires. I may also be able to use a few other parts such as the J1722 charging port (and possibly the built in charger…), but the majority of the car will be junk sitting in my back yard until I can get rid of it.

My hope is that I will be able to sell many parts from the car to help reduce the overall purchase price, and in this respect I think I am lucky that the majority of the damage was to the rear end, in that the motor/inverter/charger and front mechanical systems look to be in good shape. (If anybody wants to buy Leaf replacement parts, email me…)


Details about the purchasing process

In Georgia, due to good lobbying by the established auto industry players, only licensed “auto brokers/dealers/dismantlers” can purchase used cars at the Copart auctions, but private individuals (with some cash) can purchase Continue reading

Hexagonal wooden mirror frame

This is my finished hex frame mirror, which is the last piece of the downstairs bathroom we renovated.


I built a hexagonal wood frame out of ceder planks for the new bathroom mirror. I had originally wanted to build an irregular three sided “triangular” mirror, but once I figured out that my compound miter saw wouldn’t make cuts sharper than 50 degrees I decided I needed more than 3 sides…and 8 pieces would have been a nightmare to assemble.


I used a table saw to rip a groove in each piece to hold the glass, and then I used the flattest surface I had available (the mirror glass) to assemble and glue the pieces together. The mirror glass was original to the house, and has a 1961 date printed on the back.


Once I had the frame built, I traced out a template so that I could mark the mirror glass exactly where it needed to be cut. (Due to a few holes I was avoiding in my scrap wood, the frame is not perfectly symmetrical….)


If I hadn’t already built the frame, I would have strongly considered making a “Superman” mirror at this point in the glass cutting phase.


Adding disk brakes to a bike frame without disk brake mounting holes

The electric hub motor I purchased had a set of six holes built in for adding a 140mm disk brake rotor. Unfortunately, the bike frame I had used was not set up to mount a disk brake caliper.


I purchased the cheapest cable actuated disk brake caliper and rotor set I could find on ebay ($50) and then had to figure out how to mount the caliper. After a bit of thought, I eventually decided to keep it classy and not weld the entire thing directly to the bike frame.

Disk brake calipers are mounted using two screws, hopefully with lock washers to make sure they don’t come out. M6 SHCS (Socket Head Cap Screw), typically 1.0 thread pitch and 18mm long)

Although my bike frame did not have built-in holes for a disk brake caliper, it did have some threaded M6 holes for other purposes (racks/mudguards, etc..), so I could use one of those, and only had to add a 2nd mounting hole at exactly the right place.


From chopping apart a lot of bike frames, I had some spare steel, and one of the spare front forks also had an M6 hole tapped into it, so I didn’t even have to drill and tap the 2nd hole. I used a cut-off wheel on an angle grinder to liberate the hole and surrounding steel, then screwed it to the 2nd hole in the caliper, using the caliper body itself to hold the steel piece in place while I welded it. (The caliper also has two screws that adjust the body slightly, so the weld doesn’t have to be 100% perfect…)


Getting the small piece of steel, and cleaning off all the excess paint to get the parts ready to weld took a lot longer than actually doing the small weld. (I could have brazed the two together, but since I have the welder just sitting there, and the welded joint will be stronger, always important for brakes…)


Of course, because the brake caliper itself has M6 threaded holes, you don’t want the holes on the frame to ALSO be threaded (because then you can’t use the screws to tighten the caliper to the frame of the bike effectively) so after I had the holes positioned where I wanted them, I used a drill bit to ream the threads out of the holes on the frame. (N.B….never use a drill bit as a reamer…unless you don’t have a reamer….)

Franken-bike: Back Rack, Rain-cover support


I needed a place to mount the back of my rain cover on the bike. I also needed a place to place my electric motor controller bag. I solved both problems with left over bike parts. This “rack” is made out of the top half of an unused fork welded together. I cut a 1 and 1/8″ hole in it to go over the bottom of my seat down tube. I also put a few weld nuts I had laying around on the top of it, just in case I need to mount something else securely to it.
