Auctioning early production units as a fund raising tactic is very creative. Perhaps an article title "Raspberry Pi computer prices soar on Ebay FOR CHARITY" would clarify that the price escalation was associated with charity and not associated with extreme demand for ordinary units or people being cheated by eBay.
Sorry I didn't make it clear; Raspberry Pi is the charity that will benefit.
In fact I think they are using the auction as a way of boot-strapping some cash to pay for the manufacture of subsequent production-run computers.
The potential of a low cost ARM board is tremendous. Product development can't be easier. :) The popularity of the board goes up as there are enough support documents to get people start in no time. Needless to say, a pre-loaded OS will help. I can't wait to own one myself.
I like their move to auction the first 10 board for charity purpose. Which are the organization going to be benefit?
As far as saving when buying on eBay goes:
Use a site like Ebuyersedge.com to set up saved searches. You get an e-mail whenever a matching item is listed. Especially good for "Buy It Now"s.
Try a site like Typojoe.com to find some great deals with items that have main key words misspelled in the title. Other buyers might never see them.
For auctions, use a sniping service such as Hidbid.com to place your bid. It'll bid in the last few seconds, helping to save $ and avoid shill bidding.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Are the design challenges the same as with embedded systems, but with a little developer- and IT-skills added in? What do engineers need to know? Rick Merritt talks with two experts about the tools and best options for designing IoT devices in 2016. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
