MintyBoost attempt #2!
Hello everyone, Im going to build another mintyboost but I have a few questions. Should I use a 40 watt or 20 watt iron? Is it safe to work on a wooden table?

Re: MintyBoost attempt #2!
I'd use the 40-watt iron if you can. A 20 watt iron will probably work, but it is a little underpowered. If you work too fast, the tip temperature will drop and your joint quality will suffer. Give it some time between joints to come back up to temperature.
In any case - keep the tip clean. Give it a wipe on a damp sponge or some brass wool between joints.

Thanks, i made it and I got 4.9 volts on pins 1 and 4 and almost 2 volts on pins 3 and 4. I think the batteries I used are almost dead so im recharging them now.

Re: MintyBoost attempt #2!
So I finished the build. I used 2300 mah rechargable energizers. The batteries stay room temp but the chip on the board gets really hot. I dont know if it was just because im using it while its charging or whatever. Also sometimes I even get the temperature error on my ipod. Also when the batteries start to drain low I get the charging not supported error. I will probably invest in high drain batteries eventually. I dont want to put it in a case quite yet either. It also charged my ipod about 20% in 20 minutes so im happy it works.

Re: MintyBoost attempt #2!
Nevermind about the temperature thing, I just overreacted a bit. Im also wondering what batteries to use. Im thinking about Eneloop XX batteries

Re: MintyBoost attempt #2!
The mintyboost converter chip does run hot. It is common concern and is mentioned in the FAQ.
20% on a set of AA batteries is about what others have reported. Phones have pretty high capacity LiPos these days. Many people have reported good results with Eneloops. They do well in high-drain conditions - and are rechargeable too.
