Summarize the following:
Roundabouts are a frequent part of driving in European countries; especially France and the United Kingdom. You'll see some traffic lights, but you most likely understand how these work. Roundabouts may be a bit more challenging, even if you have driven on them in your home country. The added difficulty of the driving on the left can make the idea seem a little more daunting. Roundabouts are designed to be safer than traffic lights and they allow traffic to keep slowing rather than stop completely. Always give way to those already using the roundabout. They have the right of way. You have to pick the lane you want to use and stay in that lane until you exit the roundabout. Look for signs before entering the roundabout that direct you to which lane you should use; if the roundabout has multiple lanes. The lane more to the right is essentially for those who are making a right turn. The left lane, then, is for those who are using one of the three or more other roadways. The main thing to remember at first is just to slow down and be cautious until you get the hang of the roundabout. Try to watch the other traffic and mimic what they are doing. On roads with one two lanes, one going in each direction, you always want to pay attention to how wide the roadway is and stay close to the outside. Sometimes you may have to inch off the road a little to allow other vehicles to pass you. This can be especially tricky on streets that have cars parked at the sides. Sometimes you will need to pull up at the side and stop and give way to traffic coming from the opposite direction. Likewise, locals will often let you pass them as well. Some countries have local customs that can include breaking traffic laws. Red lights may be discretionary, and if a driver sees that no-one is coming they may pass through the red light anyway. You still want to know the laws, but you can begin to adapt to the local practices by paying attention. Still, you are the only one who has your safety and best interest in mind, so being over-cautious and defensive while you drive is probably still best.

summary: Beware of roundabouts. Pay attention to narrow roads. Drive defensively.

Summarize the following:
Get a diode a little bigger than the amperage of your panel and connect it to the bus wire, securing it with some silicone. The light colored end of the diode should be pointing towards where the negative end of the battery goes. The other end should be wired to the negative end of your panel. This prevents energy from travelling back through the solar panel from the battery when it isn't charging. Connect a black wire to the diode and run it to a terminal block which you will need to mount on the side of the box. Then connect a white wire from the short bus wire on the opposite side to the terminal block. Purchase a charge controller and connect the panel to the controller, making sure to connect the positive and negative correctly. Run the wires from the terminal block to the charge controller, using color coded wire to keep track of the charges. If using more than one panel, you might want to connect all of the positive and negative wires together using rings, to make sure you end up with two wires. Buy batteries which will work with the size of the panels you built. Connect the charge controller to the batteries according to the manufacturer's instructions. Once you have the batteries connected and charged from the panel or panels, you can run your electronics off of the batteries, depending on the amount of power you need for them.

summary: Connect the final bus wire to a diode. Connect the other wires. Connect your panel to a charge controller. Connect the charge controller to your batteries. Use the batteries.

Summarize the following:
Find a place where the item will be undisturbed and sheltered from any rain. An outside location in the direct sunlight is best. Allow the item to sit for a couple of days. The butter's oil will soften up and break up the stain. The salt from the butter, coupled with the sunlight, will help to lift the stain. Wash the fabric in the washing machine. Put a regular amount of laundry detergent in the washing machine and set it to use hot water. Do not include other items in the washing machine so that you don't risk any transfer of the ink to another item. If the fabric is not washable (vinyl, for example), wipe away the butter with a clean damp cloth. Apply a small amount of gentle laundry detergent to the cloth to help clean off the butter. The stain should be gone, but if there is still a trace, repeat the process of applying butter to the stain. Wash the fabric again and if the stain is gone, then proceed to dry the fabric as usual.
summary: Set the fabric item in the sunlight. Check the fabric before drying.
