Ok, for my birthday I got a raspberry Pi. For geeks, Sooo cute and only USD $35.: Raspberry Pi 3B+ Specs and Benchmarks SoC: Broadcom BCM2837B0 quad-core A53 (ARMv8) 64-bit @ 1.4GHz. GPU: Broadcom Videocore-IV. RAM: 1GB LPDDR2 SDRAM. Networking: Gigabit Ethernet (via USB channel), 2.4GHz and 5GHz 802.11b/g/n/ac Wi-Fi. Bluetooth: Bluetooth 4.2, Bluetooth Low Energy (BLE) Storage: Micro-SD. GPIO: 40-pin GPIO header, populated. And I've been looking at possible projects (other than just another desktop/laptop internet browser). And naturally my thoughts turned to low cost scoring machines. But what do you think a reasonable price point for a home/club made scoring machine should be? The Raspberry Pi board above is USD $35. and while it can drive small led's, a decent light source would take more power than the board is capable of handling. I also picked up some very nice 5V relay modules capable of handling 10amps at 250V AC or 10 amps at 30V DC.that were $3.00/apiece. And then the board itself can output to a HDMI or DVI device such as a monitor. So if you were looking at powering just led lights and no fancy display I believe on the order of $50. might be possible. If you scored a used monitor (flat screen, led, lcd) from someone's discard that's another option. Any thoughts on what price might make such a project interesting enough to get folks willing to get interested. Software would be what I would be interested. Probably in "C" and open source of course.
