| 15:19 | mandresc_ | hi Hebert
|
| 15:19 | mandresc_ | sorry Herbert
|
| 15:19 | Bertl_oO | hey
|
| 15:21 | mandresc_ | this is andres... thanks for your email about the axiom alpha
|
| 15:21 | Bertl_oO | you're welcome!
|
| 15:22 | mandresc_ | so as mentioned... initially I will take the alpha route for now
|
| 15:24 | Bertl_oO | okay
|
| 15:25 | mandresc_ | so the plan is to build myself the PCBA connected to the FMC connector
|
| 15:28 | mandresc_ | having said that.. can I have to the files?
|
| 15:28 | mandresc_ | access..
|
| 15:28 | Bertl_oO | https://oshpark.com/shared_projects/ahPO4XwH
|
| 15:28 | Bertl_oO | this is the easiest way to get you the PCB, but let me dig out the design files as well for the BOM
|
| 15:29 | mandresc_ | ok thankws
|
| 15:30 | Bertl_oO | http://vserver.13thfloor.at/Stuff/AXIOM/ALPHA/cmv12k-adapter-v1.1.zip
|
| 15:30 | Bertl_oO | this is for version 1.1, but the 1.2 didn't change much, I'll see if I can find the 1.2 as well
|
| 15:30 | mandresc_ | ok...seems that the PCB can be ordered, is that correct? if so do you know how much is it?
|
| 15:31 | Bertl_oO | it is 70 USD for three boards
|
| 15:31 | Bertl_oO | shipping is free
|
| 15:32 | mandresc_ | ok...
|
| 15:32 | Bertl_oO | the most expensive parts (except for the sensor) are the andon socket (sensor socket) and the FMC connector
|
| 15:32 | John-K | joined the channel |
| 15:33 | mandresc_ | ok..
|
| 15:33 | Bertl_oO | do you have a way to reflow?
|
| 15:33 | mandresc_ | no at the moment
|
| 15:33 | Bertl_oO | the FMC connector cannot be directly soldered to the board
|
| 15:33 | mandresc_ | ok
|
| 15:34 | Bertl_oO | but you can 'reflow' it on a hot plate (as first/only part)
|
| 15:34 | Bertl_oO | everything else can be easily soldered including the socket
|
| 15:35 | mandresc_ | I am planning to get a cheap hot plate from ... so I will be able
|
| 15:35 | mandresc_ | ebay
|
| 15:35 | Bertl_oO | in theory you could leave out the socket and solder the sensor directly, but I would strongly suggest not to do that :)
|
| 15:36 | mandresc_ | ok...
|
| 15:36 | Bertl_oO | you can buy one of those ceramic elements which go up to 240°C or so, they work pretty well for small size hot-plate reflow
|
| 15:37 | mandresc_ | do you know which one could a good one?
|
| 15:37 | mandresc_ | be a good one?
|
| 15:38 | Bertl_oO | something like this could work, but you probably want two of them because of the small size
|
| 15:38 | Bertl_oO | http://www.ebay.com/itm/PTC-heating-element-50W-AC-DC-12V-consistant-temperature-ceramic-Thermostatic-/351616597756
|
| 15:38 | mandresc_ | ok
|
| 15:39 | Bertl_oO | you need to place them directly below the FMC footprint and heat up the board similar to a reflow process
|
| 15:40 | John-K | left the channel |
| 15:40 | mandresc_ | ok
|
| 15:40 | Bertl_oO | i.e. keep it at 150 or so for a few minutes to get an even temperature distribution, then go up to the maximum
|
| 15:40 | mandresc_ | ok
|
| 15:41 | Bertl_oO | make sure the PCB is flat on the elements or add a flat copper or aluminum layer inbetween
|
| 15:41 | Bertl_oO | an old flat PCB with a lot of copper will work fine
|
| 15:41 | mandresc_ | ok excellent
|
| 15:42 | Bertl_oO | in any case, test the elements with some solder beforehand, it doesn't help if they are 'just' a few degrees too cold
|
| 15:42 | Bertl_oO | and I suggest to get the leaded FMC connectors not the lead free, because they reflow at a lower temperature
|
| 15:44 | mandresc_ | I'm openning the bom file at the moment
|
| 15:44 | Bertl_oO | note: for the Alpha you also need to mill a lens mount tube (we have a design suitable for Nikon lens systems)
|
| 15:45 | mandresc_ | ok
|
| 15:47 | mandresc_ | I guess the files are from Eagle...
|
| 15:48 | Bertl_oO | ebay #391452211564 or #111944929634 might be a good choice too
|
| 15:48 | Bertl_oO | yes, the design files are Eagle

|
| 16:03 | mandresc_ | about the CMV1200 sensor, the way to get it is to through cmosis?
|
| 16:04 | mandresc_ | Do you guys sell the mount for the Nikon?
|
| 16:07 | Bertl_oO | you can get the sensor from cmosis or from a distributor (e.g. mouser)
|
| 16:07 | mandresc_ | ok..
|
| 16:07 | Bertl_oO | the AXIOM Beta is using a different mount base concept
|
| 16:08 | Bertl_oO | i.e. a mount base plate which utilizes a 10mm E Mount macro tube
|
| 16:08 | Bertl_oO | this allows for various adapters not just the nikon one
|
| 16:09 | mandresc_ | ok
|
| 16:10 | mandresc_ | just checking now censor...
|
| 16:10 | mandresc_ | the sensor
|
| 16:11 | mandresc_ | wow..to get that it is going to take me some time..
|
| 16:15 | toxitobi | https://github.com/apertus-open-source-cinema/beta-hardware/tree/master/Datasheets there are the datasheets of the CMV12000 don't know if you really meant CMV1200 or if it was just a mistake
|
| 16:16 | Bertl_oO | I think it was a typo
|
| 16:17 | mandresc_ | it was.. i meant CMV12000
|
| 16:34 | foobar___ | joined the channel |
| 16:34 | mandresc_ | seems that the BOM is ~150 USD + the sensor which from mouser is ~1K5 USD..so the question now is what will be the best way to get the sensor from?

| 17:56 | Spirit532 | cmosis directly
|
| 17:56 | Spirit532 | they don't deal with peasants(us), but with Apertus they can
|
| 18:00 | Bertl_oO | actually they are quite friendly and even sell engineering samples to interested folks (at least they did :)
|
| 18:12 | Spirit532 | yup
|
| 18:12 | Spirit532 | but they sent me to a distributor
|
| 18:13 | Bertl_oO | make sense now that they are listed at mouser for example
