| 02:42:48 |  fadhliazinnuddin | In indonesia find some component which like a your project is difficult |
| 03:10:20 | fadhliazinnuddin | Both board and components ? You have |
| 18:31:53 |  kelu | Hi Fadhli, the easiest then is the fpga board, you only need it, some headers, a raspberry pi or any spi-enabled board (ftdi?) and you can work. With the modules (pulser, adc, analog procession board), you would also need more elements, and another pcb. In total, the fpga board is cheaper. |

| 00:57:37 | fadhliazinnuddin | Can I look ultrasound imaging with fpga on your web? |
| 11:53:59 | kelu | Indeed! For example: https://doc.un0rick.cc/experiments.html |
| 12:35:11 | fadhliazinnuddin | If I am buy fpga board, only board? Or with components like on your web |
| 13:16:45 | kelu | It comes like this. |

| 12:23:01 | fadhliazinnuddin | How many price ? |
| 12:23:30 | fadhliazinnuddin | So I am not need high voltage pulser again? |
| 12:23:48 | fadhliazinnuddin | Only transducer and microcontroller ? |
| 12:46:04 | kelu | Hi. It is around 450$ . Only a microcontroller and a transducer are needed. It has inside pulser (25,50,75v), variable amplifier, 64msps adc, and 500.000 pts capacity. |
| 13:01:02 | fadhliazinnuddin | Can detected using frek 2.25 Mhz - 15 Mhz to tranaducer? |
| 13:04:01 | kelu | Definitely. Sampling is up to 64mhz |
| 13:05:59 | fadhliazinnuddin | How many total price, include shiping in bandung indonesia? |
| 13:07:57 | fadhliazinnuddin | I will use to my final project in my university, I hope you can share all data all I need. Thanks |
| 13:28:41 | kelu | Yes, that is open source! |
| 13:28:56 | kelu | It is 450$ board and 50$ shipping |
| 14:14:55 | fadhliazinnuddin | How step buying ? Using paypal |
| 19:28:25 | kelu | Yes, once ready i send a invoice |
| 3 Dec 2018 |
| 11:48:15 | fadhliazinnuddin | Is board can controled freq and gain ? |
| 15:04:34 | kelu | Yes, for acquisitions up to 200us long |
| 15:31:59 | fadhliazinnuddin | Using button like a potensiometer? |
| 19:03:58 | kelu | No, everything is controlled via spi see https://doc.un0rick.cc/FPGA.html |
| 4 Dec 2018 |
| 04:51:36 | fadhliazinnuddin | So can adding button from spi to controled? |
| 04:54:40 | fadhliazinnuddin | Your ultrasound machine can to detection material ( iron casting ) |
| 12:58:37 | kelu | Control is from spi |
| 12:59:14 | kelu | Control is from spi |
| 12:59:27 | kelu | It can do, bit you need your own piezo |

| 19:17:51 | kelu | E3JX8LUT the M5Stack be interesting for you, for NDT purposes : https://github.com/kelu124/echomods/tree/master/matty/m5stack 🙂 |

| 04:04:11 | fadhliazinnuddin | Thanks for the information |
