so there is a home school group of kids my daughter is friends with, and some of the kids are into arduinos and other such stuff (just getting started i lend a few of them some of my arduino clones last week), they heard me and my daughter were build a radio (im now using tda7000 and tda2003 for it) and they were interested,
so i offered to make radios with all of them, there is 7 in total, so i went on ebay and ordered 8 of the "diy fm receiver kits"
since i have gotten a big roll of 1mm solder and made 7 spools of 5 feet long for the kids to use. but i have realized i only have 2 soldering irons, a 25w and a 100w gun.
i may need a few more, looking on ebay i have found some el chepo ones and since this will be a one maybe two time thing they dont have to be good, im soaking up the colt for solder and irons they are paying me the cost of the radio though.
i found these, (link below) they seem great for the one time use. but they are 220v 40w,
My question is if i just plug this into the 120v (north america) outlet will it work at 120v 20w?
or should i just spend the 5$ per iron and buy 120v ones.
im looking at one project use, im soaking up the cost,
7x1.5$ is 10.5$
7x5$ is 35$
i hate cheaping out but it may be the best bet now. **if it will safely work**
