The DNA20 is $50 the Nivel is $70. 510 connectors are about $2, if you want a drip well, you can make one out of a #12 finish washer ($2/pack), price of buttons range depending on what you get, but say you get the mad vapes variety, you are looking at about $10, you'll need a micro USB charging board $8 from evolve, cheaper elsewhere, several colors of #24 and #20 ga wire (price is variable depending on quantity, and where you buy it, but lets say $20). Then you need batteries. Price for those varies depending on what you get. LiPo RC hobby batteries can be found pretty cheap and come in various sizes. if you decide on using removable IMR's you increase the price a bit because you'll also need parts for holding them in. Lastly the enclosure... here you are limited only by your imagination. You can get a cheap plastic project box from radio shack for a couple bucks, or a nice aluminum enclosure from a place like Hammond for $15-30 ( I recommend using one with a removable lid or clamshell because its easier to work with). Other things you'll need are incidentals and tools. Soldering iron, solder, flux, heat shrink tubing, etc.
It would also be wise to get a breadboard (solderless circuit board) to mock up your system to ensure everything works how you want it to before you do something permanent you can't change.
I'll have more specifics in the blog. Watch for the 1st one later today.
