10/26/06	How to retrofit automobiles with halogen bulbs with high intesity discharge system The word "retrofit" doesn't just refer to cutting a parabolic reflector type headlight casing to fit a projector lens/body into it, but also to converting halogen bulb lighting to high intensity discharge. You do not "simply replacing the bulb" when you retrofit a car with HID. You have to consider wiring for the ballast, relays, signal wire (for the relay, not the clicker) and power wire to the battery. What YOU are referring to is modifying the headlight assembly which is usually done in poor workmanship e.g. leaky insert, distorted beam pattern, poor alignment, etc. and has nothing to with retrofitting the high intensity discharge lighting. You may be aware, there are two types of headlights found in automobiles: projector and parabolic reflector types. HID lighting can be used in BOTH projector and reflector headlights (e.g. First gen Acura TL used reflector type HID, current gen Acura TL uses projector type.) HID lighting can be retrofit into both types and doesn't require "retrofitting" projectors into parabolic reflector headlight casings. more »
06/04/07	How to change engine oil on a Mercedes Benz SLK - It's so easy, you won't even get your hands dirty! Thanks for your responses! This is a long-running debate and there are "drainers" who can't imagine a simpler way to change oil is better than getting under the hood. New Mercedes are designed to have oil sucked through the dipstick tube. The evac method will get just as much oil out as getting under the hood. It would be fair to say when the engine is warm and the oil has been circulating, solids are suspended in the oil and would be "sucked" out with the oil via a pump. Drainers wouldn't do an oil change without warming up the car for the same reason or the sludge will just sit at the bottom. If you prefer to drain the oil, that's fine. I've had this discussion with many "drainers" and it's like trying to persuade a vegetarian to eat a filet mignon. Just for fodder, even Car Talk guys agree with me. :) http://www.cartalk.com/content/columns/Archive/1997/July/09. more »
06/19/08	How to Do a Proper Push-Up Need more challenge? Few more variations: - Hands at head level - Normal pushup setup but keep your elbows close to your body when doing the pushup. This is the plank move in yoga. - Bring your hands together forming a triangle with your index fingers and thumbs. You really give your triceps a workout and require using other upper body muscles to balance yourself. - Don't forget the ultimate: One arm pushups!! more »
03/25/08	How to change engine oil on a Mercedes Benz SLK - It's so easy, you won't even get your hands dirty! Greetings all! Just wanted to respond to some of the new comments: - Yes, MB cars have drain plugs.:) - Most auto part shops accept used engine oil and coolant which are recycled properly. Most city dumps also accept used oil which are recycled. - Please feel free to drain engine oil if you believe it removes more oil than evac through the dipstick tube. I have experiemented doing it both ways and found no difference for my cars. I even used rapair ramps to tilt the car when removing the oil via drain plug to get as much oil out as possible. Last food for thought: I worked as a journeyman mechanic in my college days (to pay for books and beer of course.) I have seen plenty of oil pans with 1/2" thick sludge inside. Apparently how oil is removed isn't the real problem. It's not maintaining the engine and changing the oil regualarly that causes the sludge issue. more »

09/17/07	How to Buy A High-End Plasma TV While the half-life of plasma TV was a concern few years back, it is no longer a decision point. The technology has improved to the point that most plasma TVs have half-life of 10,000 hours or more (Panasonic and LG/Philips both say they have improved the overall life span of their newest plasmas to 60,000 hours - more than 20 years if you watch for 8 hours per day.) Burn-in is still an issue but not as much again due to technology improvements. LCD TVs eliminate the burn-in issue with loger life. The next technoloy coming down the pipe is LED TV has no such issues (along with LCD) and will allow the TV images to be more definitive with claimed better color reproduction along with even thinner profile casing (1-2" depth instead of 3~4" depth for 42" plasma and LCD TVs.) more »
