| 00:19:15 |  jchaput82 | Ah, super ca! Tu connais Alexandre Aubry? On publie ensemble dans le domaine geophysique, un truc pour vastement ameliorer l'imagerie de la sorte qui t'interesse (c'est a dire, une version fortement modifiee de l'imagerie confocale classique). |
| 01:32:09 | jchaput82 | Par contre, le processing est completement DSP. Sur un autre point, la phase et l'amplitude de la reception pour ce que j'envisage sont tres importantes, donc le signal brut (sans processing sur le hardware) est ce que je voudrait enrigistrer. |

| 02:17:04 | shcup2002 | where did you get this probe?? do you know Link??🙂 |
| 12:49:02 |  kelu | I don't know link, what is it? This is from Shenzhen, magical land of troves. |
| 12:57:36 | kelu | Btw, avec la petite carte, tu peux faire du 8 io independant, and given the small cost of the board, you can put a couple of boards in parallel to get raw signals. I'm interested in the papers about this type of work :) |
| 12:59:02 | kelu | Tu connais Nicolas E. aussi ? |

| 07:28:26 | wotlr6427 | Hello I am a student who is trying to make an ultrasound device. I have an in-progress question. We saved the un0rick board through the site.
https://doc.un0rick.cc
I followed the blog to create an ultrasonic device. After completing the operation and connecting it to the Jupiter notebook, the result data will continue to be 0000000 and ask for help. I would like to know what part of the board is jumping and what about the data sheet on the board. |
| 07:31:04 | wotlr6427 | The board is the board we ordered. I would like to know where to connect the jumper socket and jumpers and the board information. |

| 10:54:33 | kelu | Hi @room, been working on a fast 101 documentation of the un0rick board, see attached - would be glad to have some feedback with respect to it being easily understandable or not.
As a bonus, this PDF not only has the documentation.. but if you rename it as a zip file, it will become a zip that contains the hardware and software codes, as well as an acquisition example 😃 |

| 13:44:38 | kelu | Hi Andras, hows the balance moving forward? I had read the july news from hackaday, looks good 😃 However, the RPi is not real time, and may induce delays in ADC acquisitions.. how do you manage this without a FIFO (or ic / fpga) between the two ? |

| 17:39:21 | kelu | Another goodie for debugging.. an impedance analyser. Here hooked to a double peak transducer.
50$ on eBay makes it useful to check piezos connections.. and for reverse engineering as well :) |
