Nov 23, 2016 at 9:54 comment added bdutta74 not sure if you've been on ESE for very long, but the general drift is that this is not really a Arduino'sque lego-block construction (aka Maker) community, although you'd find plenty Q&A along those lines. Q&A that have embed fundamentals of electronics theory are better appreciated. As I wrote, I liked the answer for practicality of approach. Yes, much water has flown under the bridge in the last 5 years.
Nov 23, 2016 at 0:47 comment added Parakleta I didn't know about "product recommendation" policy. I specifically didn't link to anything since I was just providing general suggestions though. I find 90% of electronics engineering these days is product/source/price of components to achieve a final product with the required functionality for the best price. I know the question is quite old, but unfortunately stack questions live for ever and need new answers as technology and solutions change. 5 years ago the little USB boost devices existed as "USB Emergency Charger" for $10 as finished products you would have to dismantle.
Nov 22, 2016 at 7:36 comment added bdutta74 As the OP, I liked the answer and upvoted. ESE is extremely strict about "product recommendation" policy. Things that talk of specific products, sources, price is frowned upon -- been burnt couple of times. However, in the overall context, I think you've edited the answer to add nature of information that is considered useful and generic (which is why the up-vote). The question was asked 5yrs back, and IIRC such ready-to-use 'blocks' were not readily available.
Nov 22, 2016 at 0:54 comment added Parakleta Why the downvote? OP wanted the least expensive solution which I think I've provided.
