\"Flavonoid<\/a><\/p>\n

I could say over<\/em> design, but zealous sounds more purposeful.<\/p>\n

So, zealously over designed peculiar digital life-game controller here. Added a coin cell holder for a 3v coin cell (12mm) to keep the RTC clock going if power drops or is removed. Added an on-off switch(!) Added two extra components to the power management circuit \u2014 a MAX4651 for the really off situation in which I use a removable battery and insert the battery backwards, and a MAX6439 battery watcher deal that’ll signal the MCU if the battery goes below a specified (factory trimmed) voltage, pull down reset if it goes super low, and signal if it rises back above a threshold, with a bit of hysterisis. Problem was that the thing could drain the battery into oblivion which made recharge long and tricky. But, frankly \u2014 now with the on\/off switch and battery back-up for the RTC, it’ll be much easier to charge over USB. I hope. Found some small LiPo batteries from an iPod Shuffle battery replacement kits, of all things. One is 230mAh<\/a>, the other one says it’s 400mAh but it’s marked 330mAh<\/a>. Close enough for Jazz. It’s about 37mmx22mm.<\/p>\n

Also I found this operation:<\/p>\n

www.synst.com.tw\/english\/prdlist.aspx<\/a><\/p>\n

They sell small, flat, light LiPos with decent capacity (160mAh+\/-), but much more expensive and harder to get.<\/p>\n

Curious about what’s what? The Flickr page has “notes”.<\/a><\/p>\n

Update. The iPod replacement batteries work great so far.<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"
