May 11 10:07:36 <thetransformerr> jkridner: I wanted to know if u had placed order
May 11 10:09:49 <thetransformerr> nerdboy: I was thinking initially for sonic transducers, we can go like this
May 11 10:10:48 <thetransformerr> 2 pair of transducers where each transducer is either tx or rx
May 11 10:11:16 <thetransformerr> and one pair of transducers where each sensor is transceiver
May 11 16:22:04 <nerdboy> thetransformerr: you mean for testing?
May 11 16:22:17 <thetransformerr> yup
May 11 16:23:45 <thetransformerr> and I again visited last year repository, but couldn't find anything useful
May 11 16:24:04 <thetransformerr> did that project was completed or was abandoned
May 11 16:24:07 <thetransformerr> ??
May 11 16:35:57 <nerdboy> he switched ADC boards at the last minute
May 11 16:36:13 <nerdboy> so, not very successful...
May 11 16:36:51 <nerdboy> what you(we) need to do is understand the signal conditioning reqs
May 11 16:37:19 <nerdboy> what comes out of the sensor and what needs to go into the dac
May 11 16:38:05 <nerdboy> isn't there some example circuits in the data sheet?
May 11 16:48:53 <thetransformerr> I am digging on that, up till now I have seen few circuits, some of them were present in a book related to these experiments
May 11 16:49:56 <ds2> what are you trying to do?
May 11 16:50:11 <ds2> build up something or just research?
May 11 16:50:22 <thetransformerr> in one circuit the main logic that determined, time of flight was the time period b/w receiving of direct transmission and then reflected wave
May 11 16:50:53 <thetransformerr> surely build up something, but with proper implementation
May 11 16:52:49 <thetransformerr> the input to these sensors are square pulse wave of 40 kHz and the receiver give output at diff time positions that correlate to time period involved in travelling of distance
May 11 16:53:13 <thetransformerr> please wait I want to show example of waves output from receiver
May 11 16:55:31 <ds2> time of flight? thought we are measuring freq shifts?
May 11 16:57:35 * mr_science has another mtg...
May 11 16:57:56 <thetransformerr> freq shift is another alternative for tof
May 11 16:58:41 <thetransformerr> I am currently focusing on time of flight,
May 11 16:58:43 <thetransformerr> http://sensorwiki.org/doku.php/sensors/ultrasound#time_of_flight
May 11 17:10:44 <thetransformerr> ds2: we can implement a part of circuit as per our requirement without much hassle?? https://usercontent.irccloud-cdn.com/file/3DCoPPJW/Screen%20Shot%202017-05-11%20at%2010.38.40%20PM.png
May 11 17:13:18 <thetransformerr> this is what I am going to test with oscilloscope in my college, before coding starts https://usercontent.irccloud-cdn.com/file/LuiiKtRm/Screen%20Shot%202017-05-11%20at%2010.38.04%20PM.png
May 11 17:54:30 <nerdboy> thetransformerr: https://sourceforge.net/projects/arduinoweather/files/  <= can you check the sensors/circuits this guy used?
May 11 17:55:03 * nerdboy has to finish his giant kernel patch...
May 11 18:03:46 <thetransformerr> I would get back to you till tomm
May 11 18:48:09 <ravikp7> jkridner: I had a chat with etcher developer on resin-io channel on gitter, he confirmed that they are working on building an etcher sdk, which will be a re-usable module that will contain everything needed to flash an image to a drive (e.g. unmounting, elevating etc). The sdk will be released in a month, so sdk should make the task for wraping it in a gui
May 11 18:48:09 <ravikp7> would be easy along with the bootloader server.
