| 08:39 | topi` | the holidays are about to start... but the projects won't wait :( |
| 08:39 | topi` | jnettlet: would you think SERDES can be used to reconfigure the SIM card used on-the-fly? |
| 08:40 | topi` | there are 2 sets of SIM signals on the CF Base (and CF pro as well) |
| 08:40 | jnettlet | topi`, those are hardwired to their respective connectors as per the spec. |
| 08:41 | topi` | OK so only that card in that very same slot can access the signal? |
| 08:41 | jnettlet | correct |
| 08:41 | topi` | but if it is a WiFi card, then my bet is that it won't touch those signals |
| 08:41 | topi` | so maybe a few jumper wires could do it... ;) |
| 08:42 | jnettlet | yes, you could probably figure something like that out |
| 08:42 | topi` | so basically also the M.2 slot on CF Base could receive a 4G modem? |
| 08:42 | jnettlet | yes |
| 08:43 | topi` | good news |
| 08:49 | topi` | jnettlet: my guess is, if we make a hardware switch that switches between the SIM0 and SIM1 , we cannot just use jumper wires because at any one time, one of those SIMs should *not* receive +5V at all |
| 08:50 | jnettlet | topi` correct you will need to switch all the signals at once |
| 08:50 | topi` | so, a better thought would be to create a small daughter board, that seats 2 x SIM, and there is a mechanical switch to feed +5V to one of them, exclusively |
| 08:50 | topi` | and since there is an empty space for the SIM connected to M.2, that would be a suitable place for such a daughter board |
| 08:50 | topi` | either directly mounted, or via wiring |
| 08:51 | jnettlet | I am pretty sure such a device exists |
| 08:51 | jnettlet | I have seen them for mobiles |
| 08:53 | jnettlet | http://www.simore.com/en/multi-dual-sim-adapter-case-4g-iphone-6-x-triple-6.html |
| 08:54 | jnettlet | They make lots. http://www.simore.com/en/dual-sim-card-adapter/dual-sim-3g.html |
| 08:57 | topi` | :D |
| 08:57 | topi` | simore.com, that's a suitable name |
| 10:55 | topi` | OK I think we have it all now, so let's start courting the customer :) |
| 10:58 | jnettlet | topi`, good luck. and merry christmas |
| 10:59 | jnettlet | or happy holidays |
| 11:02 | topi` | I'll survive :) the children are exstatic |
| 11:02 | topi` | this is the darkest time of the year in the northern hemisphere, so not very friendly to brain chemistry |
| 11:03 | topi` | I guess I'll just increase my chocolate intake :) |
| 11:18 | topi` | we'll get back in business in January :) |
| 11:20 | jnettlet | topi`, yeah. DK is only at about 6 hours of daylight each day at this point. |
| 12:51 | topi` | I had to revise my plans. It seems the M.2 slot in CF Base cannot take usb peripherals, just PCIe and SATA |
| 12:51 | topi` | the connector is of type M |
| 12:51 | topi` | where notched pins are 59-66 |
| 12:52 | topi` | oh, I was looking at CF Pro schematics |
| 12:54 | topi` | oddly enough, the UIM signals and all do get routed to the M.2 in the Base model... |
| 12:55 | topi` | oh it explicitly says "M.2 model B" there, I think that settles it |
| 12:55 | topi` | can use LTE modems there :) |
| 13:03 | topi` | I just realized something interesting... since the Schematics for Solid-run products are available, it's entirely possible to actually fix the boards if something gets broken |
| 13:03 | topi` | this is totally not the case for most electronics today |
| 13:04 | topi` | I'm thinking of some big clients here who might want to cling into the same HW for 10 or 20 years |
| 13:07 | jnettlet | Well most are chips are industrial grade so 7 years support from the soc manufacturers |
