cooper Posted April 26, 2014 Author Share Posted April 26, 2014 Things to improve the design: If it was me making this, I'd use an Odroid and if you weren't expecting that, you haven't been paying attention. I'd probably have a hard time pairing the thing with the touchscreen. Can't find a decent replacement for that. As for the rest... This SIM900 board is roughly the same size (8x6cm) but costs a tad under $30. The battery. This bloke paid 15 bucks for a 3.7V 2.5A battery. Amateur. ;) Here are those same specs for half the price or even almost the same specs for a third. This one's got 10% more amps and is still under $5.50 whereas this one even looks the part but comes in at 3A and still just over half the cost but the winner, for me, would be this one at a cost of $10 you get over 13Wh. Next the boost converter. Here's one matching his specs for under $5. Totalling, 75 for the pi and screen and a further 45 for the bits mentioned above and a final $10 for assorted cables, connectors, switches and the lot. Comes to $130 or about $30 under what he's paying for it. Any takers? :) Quote Link to comment Share on other sites More sharing options...
WindyCitySDR Posted April 27, 2014 Share Posted April 27, 2014 Sounds good! I'm putting out SDR MIMO devices able to EASILY create GSM Mobile Phone Networks next month. + a new wideband handheld SDR that I demonstrated before SDR-Winncom, or www.WirelessInnovation.org before Motorola Solutions in March. This PiPhone you posted about is pretty cool! Quote Link to comment Share on other sites More sharing options...
cooper Posted April 27, 2014 Author Share Posted April 27, 2014 (edited) Interesting. Got some info on these devices of yours? Found it. Massively impressed person sitting behind a laptop here. What's the expected price tag of this device and can/will it be shipped internationally? What are the major parts you've put on there?
