varistor is a blue coloured component, that would be removed. picofuse is a brown coloured button like component, that would be replaced.

In other words remove varistor and solder the pico fuse? What Amp to get for picofuse? I just remove the varistor. Only thing is I pray there is no power surge else my power socket will fry.

I just paid my Roomba 550 for SGD 381.17 (USD 268.99). I supposed paypal is offering better exchange than the banks right?

paypal exchange rate is one of the lousiest, 1USD for 1.4196SGD. UOB bank rate is 1.3910.

voltage is never a wastage lar, it's the current drawing that affects the total energy.

btw, where do you guys get the component to mod ah?

so a stepdown doesnt waste energy?

 

[sAxman_Returns]

the energy wastage is not because of the voltage but current I supposed?

btw, how can I add my won item in ebay for comgateway huh? click here click there still can't add de neh....

dunno which stupid idiot design that website, it's so user-unfriendly.....

 

[sAxman_Returns]

so far i saw at home-fix and other DIY shops are all "Converter" - NewStar brand etc (although the box got write transformer) .. did anyone managed to find a real transformer?

I read somewhere that it's better to get a transformer then converter.

[mingkiat]

see this one http://kevinandsusie.blogspot.com/2007/05/adaptors-vs-converters-vs-transformers.html

# Converters are for single volt Electric products with simple heating devices and/or universal motor products such as garment steamers, irons, curling irons, etc. These products are generally used for short periods of time. Step-down converters convert 220/250V foreign electricity down to 110/125V domestic electricity by cutting the number of volts flowing into the appliance in half.
# Transformers are for single volt appliances with Electronic circuitry (computer chips or integrated circuits) such as computers, fax machines, answering machines, T.V.'s, power tools, cameras, phones, etc. Like converters, transformers can either step-down the voltage or step-up the voltage. Do not use a converter with these products

refer to http://forums.hardwarezone.com.sg/showpost.php?p=27666059&postcount=1696. replace capacitor C1 rating from 47uf @ 200V to 47uf @ 400V. replace pico fuse F1 to 1.6A 250V.

[jc777]

so a stepdown doesnt waste energy?

remember in my sec sch physic lesson, P = I x I x R, meaning, got current flow => got energy lost.

in layman's term, is the transformer hot when it is in operation? if hot, means got energy lost as heat. and also make the house hotter and need to turn on fan / aircon to cool down. double wastage

think my mod not complete. Think need to make a trip down SLT
