Scalectrix Lap Counter Project Analyse

The scalectrix lap counter requires constant low voltage power, for it to work. We cannot use the mains power, as its dangerous and can be fatal if not used correctly. As the scalectrix user age is around 5 to 14. Using direct mains power will be even more dangerous; however we can use transformers to lower the voltage and current. Also we can use batteries to power the project.

The many types of batteries out there in the market, these include AA, AAA, C, D, 9v. Also lantern and car can used, however there are less portable and heavier. One major advantage using batteries over mains power is, the counter can be used anywhere.

Batteries

Zinc Carbon – One of the most basic batteries also it’s a cheaper alternative to the alkaline. This batteries isn’t suitable for projects that require high output also the voltage drops during use.

Alkaline – The most commonly used battery and longer life than the zinc carbon batteries. However it will cost you more to buy alkaline batteries than the zinc. Another advantage of the alkaline battery, its voltage level doesn’t fall as quickly as the zinc carbon battery also has much higher capacity which means it’ll provides more amps per hour.

Silver Oxide – Very ...
