Next steps from Murgen
- Playing with the design and fab the modules: 3 to go in CMS (HV/TGC/MD, enveloppe detection, SPI ADC) and 2 in stripboard mode (alim, based on the breadboard 3.3V and 5V, as well as the controler, maybe an arduino nano at first) - and start the github repo / echOmods hackaday pages as well. Work on this with Sofian and Vlad. See also the echOmods repo.
- Playing with an electronic emulator of the transducer - as well as an electronic model. Work on this with a partner/supplier. Actually produced in the end with a uC - Silent.
- Play with a ultrasound durable fantom. Work on this with staticdet5 (commnotes_ent on HAD). Started a project with Virginie and Static on HAD.io.
- Play with the BeagleBone PRUs. Work on this with Vanderbilt.
- Playing with some intelligent uC of FPGA. uC has my preference at first for ease of use. WifiMCU seems fun (has a 8$ STM32F411CE - 100MHz, 2.4Msps ADC, FPU, DSP instructions and WiFi to stream!) or the Feather Wiced (arduino IDE compatible, based on a 34$ STM32F205 ARM Cortex M3 processor running at 120MHz. Project codename would be Croaker, not created yet. Who's volunteering?
Mostly, the thing would be to separate the Murgen PCB in 4 different modules (similar to the arduino trinket pro for example), so to have them ready to be used on a stripboard which would have already headers.
The strips would have the 19 tracks as on the attached picture below.
There would be 2 modules :
- HV + pulser + md0100
- TGC + enveloppe + SPI ADC
(Two other modules, Alim, and controler, will be stripboard based)
Given that the boards would be separated, would it make sense to try to **design the PCBs to have only 2 layers PCB** ? The width of the PCBs would not really matter, only to be sure they'd fit on a strip board. It would be interesting to have a form factor of the modules PCB comparable to one trinket pro =)
- 10ms between lines - 64 lines gives 640ms / image)
- 200us at 2Msps is 400 points is 5600 bits is 700 bytes
- 5600 bits per 10ms is 560,000 bits/s is 70kbytes/s.. should be OK with ESP8266 ;)
1. HV+Pulser+MD0100 don't change. The module will need to have a SMA connector (same as on existing board).
2. VGA + enveloppe + ADC
- VGA+enveloppe detector can remain the same. I just need to remove the filter that is between t he TestPoints4 and 5 and the transformer. The module output is the output of the ADL5511.
- SPI can be replaced, this one was an overkill. 10Msps is too much, so instead a 2 or 3 Msps at 12 or 14 bits in SPI could be used on the ADC module.
The "controls" listed would be a potentiometer for the HV (as was done for murgen), a potentiometer for the TGC Gain (not an ADC, bit of overkill, rather a jumper to allow one to select the gain from either the track or a potentiometer which would feed in from 0 to 1V).
The ADC can be as low as 12bits 2Msps when we're talking about envelope detection (what about MAX11105?). (btw, the signal output by it is offset by around 1.32V) on top of which we have 1.25V of signal. For the sake of the experiment, I would add another ADC board, clone of the 11105, with a MAX11103, to comparatively test both.
What is expected is to break down logic blocks into modules that could be put on a motherboard ( a 2.54mm stripboard), 19 tracks high.

Board 1, aka Tobo:
- The HV part of murgen is kept. The pulser of the first board is trigged by Pulse On (stripe 9) and shut by Pulse Off (stripe 10) (coming from the stripes). The pulser alimentation is fed through the RECOM component, with a potentiometer to select the HV level.
- Signal is sent to a sideway SMA connector.
- Signal is protected by a MD0100 + LC.
- Low voltage signal is sent out of the board through a SMA connector.
Board 2, aka Goblin:
- Low amplitude signal comes from the SMA connector.
- It is fed through to the TGC.
- The Gain of the TGC can come either from the Analog Gain Ramp stripe (stripe 7) or from a potentiometer which gives it 0 to 1V - selection through a jumper.
- The filter part of the murgen board is removed (between TP2/3 and TP5/6)
- Raw signal is either send to stripe 3 or sent to the ADL5511, selection through a jumper.
- If output of the TGC goes to the ADL5511, it is then sent to the stripe 5 or to the 2/3Msps ADC (SPI).
Two other modules are being worked on, namely:
- controler
- alimentation
- TLDR
- CapTech Workshop. Was great!
- Acted upon a split between a FPGA long-term approach, and a non-FPGA one. I remembered those good old times when this was a possibility.
- Damn it. What if I could dig into this? Not µC, rather an extension for an existing computer.. or mini computer.
- Saw some ideas on the Arduino's side. Separate ADC.

- How to use it?
- http://www.element14.com/community/community/designcenter/single-board-computers/next-gen_beaglebone//blog/2013/05/22/bbb--working-with-the-pru-icssprussv2
- For low-speed comms, conventional I2C or similar protocols can be used, and there is no need to use a PRU. For high-speed comms the PRU may be extremely useful because it can service the hardware with no interruptions due to Linux context switching, and no overhead is experienced by the main ARM processor. Here are some examples that should be feasible; basically quite a few possibilities, such as
-
- interfacing to a fast ADC (e.g. analog capture)* * ,
- https://theembeddedkitchen.net/beaglelogic-building-a-logic-analyzer-with-the-prus-part-1/449 BBB is a 100MHz logic analyzer on a BeagleBoneBlack
- Demo over the http://beaglelogic.github.io/webapp/
- http://r.git.net/beagleboard/2013-10/msg00204.html
- Can the PRU be used to interface the Beaglebone to external ADC? I need to capture 500 micro-seconds of data at a 5 MHz rate.
- -> * It depends on the interface to the ADC. There is a parallel capture interface that will easily run that fast, and you may be able to use the bit-shift interface to do serial or something like SPI if the PRU's capability lines up with what your ADC wants to see.*
- http://www.element14.com/community/community/designcenter/single-board-computers/next-gen_beaglebone//blog/2013/08/04/bbb--high-speed-data-acquisition-and-web-based-ui
- In its current state, it grabs analog data from an ADC, and dumps it into memory on the BBB, ready to be displayed or further processed. It could be used for gathering analog information from sensors, CCDs or other data acquisition use-cases. To be reasonably useful, the desire was for it to support 20Mbytes/sec of data or more. It does achieve this, but it is for further study to find higher speed methods.*
- This is not such a bad idea, because in future the ADC could be swapped out to a (say) 10-bit ADC with no code change on the PRU.*
- Once the data has been captured (2000 samples in this example), the command byte is acknowledged, so that the Linux hosted application can know that the PRU has completed. The PRU now sits and waits for a new instruction from the Linux hosted application.* * -> works for us - fixed depth = fixed # of samples
- Buffer to be used : detailed at
http://www.element14.com/community/community/designcenter/single-board-computers/next-gen_beaglebone//blog/2013/08/04/bbb--high-speed-data-acquisition-and-web-based-ui
- ''These were extremely important for two reasons. One reason is that the pins to the BBB that I wished to use need to be isolated during power-up, because they are used for selecting the boot method. If there was any unusual level on the pins upon power-up then the BBB will not boot from the eMMC. So, a tri-state buffer is needed. The other reason is that there is a fair bit of capacitance and it is highly likely that the ADC may not be able to directly drive the pins at high speed. I actually came across this problem while trying to connect a camera to the BBB. I struggled for days without realising that the camera could not support the load. So, the buffers are likely to be essential for most designs using the pins that were selected. I used a 74LVC244A device as a buffer. Note that the clock also needs a buffer, unless significant jitter is acceptable. No tri-state is required here, so I used a MC74VHC1GT50.

- 16 bits : is it possible to set all 16 pins on pru0 as inputs? I saw you mentioned something about disabling the microSD functionality on the BB to get access to all 16 pins, but I wasn't exactly sure how. -- heartofasquid I thought the PRUs had a 16bit parallel capture mode or are all the pins not available on the BBB? (need to consult the docs) section 4.5.2.2.3.2 of the tech ref spruh73c.pdf One thought I had was to use both PRUs to capture alternate bytes/words but that was just a thought, again are all the pins available? I'd made a mistake, it looks like all of PRU0's GPI pins may be available, if we are happy to lose the microSD (no big loss - there are other ways to get data in/out of the BBB). So, we can theoretically get high-res captures up to about 15bits, if we need 1 pin for the clock.

Nice reading =)
- Basecamp outlines their goals -- which they say have always been the
same -- on their website:
- Have fun
- Do exceptional work
- Build the best product in the business
- Experiment
- Pay attention to the details
- Treat people right
- Tell the truth
- Have a positive impact on the world around us
- Give back
- Keep learning.
- "We’re also big believers in business 101. We don’t spend more than we earn, we don’t waste money on things that don’t matter, we don’t give away everything for free and hope we’ll figure it out before we run out of cash. We’re in business to stay in business, and we have 15 profitable years in a row to back it up."

Choice of a uC: "le boulot des microcontrollers, ce qui me gene sur l'espruino c'est le manque de sortie wifi - si on veut sortir des donnees en wireless." Deux choix se profilent
- WICED : STM32F205RG 120MHz ARM Cortex M3 MCU : 17 timers et 3 × 12-bit, 0.5 μs ADCs with up to 24 channels and up to 6 MSPS in triple interleaved mode, 8- to 14-bit parallel camera interface (48 Mbyte/s max.)
- Le WifiMCU : EMW3165 : M4: STM32F411CE @100MHz, DSP+FPU, 1×12-bit, 2.4 MSPS A/D converter -- Ce qui me fait peur est un WifiMCU de base en LUA, a voir comment repasser sur du plus bas niveau. L'avantage par contre c'est qu'il est dispo chez hackspark, et coute 18€ au lieu des 35$ du WICED =)
Remarques : Avec le M3 tu perds les instructions DSP et un FPU optionnel (cf https://en.wikipedia.org/wiki/ARM_Cortex-M). Par contre je ne sais pas si c'est correctement exploite, ni si on en a vraiment besoin.
Il y a aussi le Module Particle "Photon" http://www.lextronic.fr/P37394-module-particle-photon.html (M3 120 MHz et wifi) ou l'Arietta http://www.lextronic.fr/P32050-module-microcontrole-arietta-g25.html

More stuff about Phantoms: http://meritus.kopernika.pl/homemade-tastes-better/
And ... working on the 2016 Summer presentation.
- Working on the milestone presentation.
- Received a 12V alim, the PRUDAQ, and pushed the issue with Silent onto github. Ongoing !
- Working on the finance file --> still work to do !
- Setting the stuff on for 1000$ from HAD
- HD should have received the pulser module.. waiting for it =)
- Worked on the doc-test script to automatize the results of modules documentation tests -- see an example with an error
- Received tobo !! yeayyy
- Playing with Doj and assembling the board (tobo, goblin, oneeye and mogaba). Should be enough to get first images.
- power seems OK, first pulses look nice
- Todo: test with my transducer for Cletus, and with ATL3
- Thanks to Virginie for her support on debugging Doj !!
Roughly, all the modules are fine. Emulator is done and tested. Some tests today:
- Test Analog Processing + ATL3
- Test Emulateur de signal + Analog processing
What the next steps are :
High priority:
- Use PRUDAQ
- Clip the signal between 0 and 2V
- Get image from the retroATL3
Medium Priority:
- Bitbang Goblin's SPI directly
- Resume documentation
Low Priority:
- EMW3165 to move forward
- Cletus for Servo + Piezo (and mech parts) - using SmartMaterials piezos
- Clipped the signal
- Documentation ongoing
- Received TFT+Servos
Awesome work: a FPGA on a RPi0 footprint
- Read some on this page: got an image from a ATL3 probe, a small metal cube in water.
- Leaving for holidays =)
- Working with Virginie and Benoit to get images
- Got to play with a general multi tissue fantom: got an image from a ATL3 probe, of the fantom.
- What about using Kaggle as a data repo for open data ?
- Yeay!! Done. Gitbook available on this page
- Showing the documentation generation process on an apero at l'Hotel Dieu
- Thanks to a question raised by a sharp-eye, I'm putting as a disclaimer that this project is not one supported by the echopen's association. Even if I'm a cofounder of echopen, this project is a personnal one, for the echopen community. Clarified with hackaday, not an issue for them wrt the prizes.
- got contacted for a partnership to improve, build, and crowdsell a set of modules. Interesting!
- Got some feedback of PRUDAQ's people on the doc, thanks to them for this contribution!
- Zach's been back. Let's see what can be done.
- Prof Charles is going to be in Paris: let's meet!
- Been invited to speak at Hackaday's show for its prize on Nov 5th
- Trying to get the latest HV7360 from MC.. seems difficult to say the least
- Thinking about the use of the "Logiciel and Objets libres, animer une communaute autour d'un projet ouvert"
- Interesting : STBone - BeagleBone form-factor STM32F427 board
- Doing some thinking about the servo part -- should be integrating a feather + screen to help debug the output =)

“We do not grow absolutely, chronologically. We grow sometimes in one dimension, and not in another; unevenly. We grow partially. We are relative. We are mature in one realm, childish in another. The past, present, and future mingle and pull us backward, forward, or fix us in the present. We are made up of layers, cells, constellations.”

Given RPi0 capabilities in terms of GPIOs - why not push it to 20Msps, 8 bits, for the cape?
Netty isn't nice... but just got my article accepted by JOH !
-
Updated the suppliers repo

- Indeed. Forgot to add a ADC input directly from a strip, two strips for PulseOn and PulseOff, and a way to control the servo from the Pi.
- Also starting the new season of the HackadayPrize =)
- Still some issues with bomanz (on HAD) PCB. Some pads suck. I guess I'll order the board from OSHPark along with Doj's and solder all these tiny stuff. Not so many actually.
- Posted the Chinese probe project on Hackaday. Will play with the probe using a RPi framework. Should do the trick =)
- Following up on 6Msps upgrade, mother board seem OK, silkscreen to do, then Pi1 and Pi2 to follow.

- Moving forward! Capturing some images from the probe, trying videos
- Got some PCBs for Bomanz, for both high speed and CA3306E ADCs.
- Got some PCB for Doj, and tested those!
- Playing with DICOMs on Kina, should be ported to all images. Example of code yields funny dicoms.
- Here's what the ADCs boards look like.
- Tantalum capacitor: not in reverse! Never!! What are the odds that I put all 3 capacitors on 2 different boards all in reverse ?
- That's well and done. Shall be trying this week end!

Got some amazing responses to the post on HN, held the 1st pos for an hour +, got over 200 ups, that's quite enough =) I guess I'm coming close to an end on this project, and my target would be to try and have a presentable project before Year 2. The five key milestones:
- Outreach: I have sold 10 kits so far, have ordered 5 sets more to a CN PCBA. Will sell those - and let people choose what they want when they'll want to play with those. I guess I'll have the community Milestone reached when someone provide a significant improvement / publishes thanks to this kit. Status: 50%. Bonus point if a unreached continent so far is involved.
- ENDOFYEAR: 15 kits sold, CN not good, MF ongoing (20171217)
- Money: thanks to the small margin on kits, and hackaday prizes, i'm quite cash neutral as of today. Having the 5 kits sold would permit financing the acquisition of the unmantled CN probe. Status: 100% Bonus: trade the chinese probe on leboncoin / ebay. Status: 0%
- ENDOFYEAR: still waiting (20171217)
- Product: I wanted to have a ultrasound hat done. I now have this ADC pHAT done, which can be perfected, but it's quite a win, so a simple 80V monopolar ultrasound board (independant from the motor / multiplexer) could be reached by Nov. Status: 0% Update: could be good to use the probe head to do a full portable probe =)
- ENDOFYEAR: Ongoing with Matty (20171217)
- Documentation: There are a couple of notes here, I'd love to see all of those gathered / processed / put into a braindump. Gitbook is good enough, but lack structure for raw knowledge dump. TODOS include:
- Listing all docs under YYYYMMDD
- ENDOFYEAR: Quite happy, having added experiments (20171217)
- Future I'd be keen on having a 8 to 16 elements module prepared, just so to prepare the next gen and passing over of the project. Jan and Ivan to support. Status: 0% Muxing using ATTINY85 ?
- ENDOFYEAR: Shifting to chaotic masks ;) (20171217)
Nice to have:
- A slack bot? It would be fun to have a supporting bot to answer queries, like "where are the elements benchmarked, how do you process dicom, ..."
-
Added something about the S3 probe
-
@done Adding the descs for modules and power needs
-
@done Removing double Autogen tags
-
@done Main readme as TPL
-
@cancelled DICOM rest of images
-
@done test some compressed sensing using golay codes on a single element piezo

Commands
- modprobe foo parameter=value
- modinfo ambassador for params
Sometimes a kernel modules allows setting a parameter at run time. In this case you'll find the parameter under /sys/module/modulename/parameters/, with writable file permissions. The debug parameter of the ambassador module is an example of such a parameter. Set a value to this parameter with a simple echo command:
echo -n 1 > /sys/module/ambassador/parameters/debug

- Worked on a bard probe with matty
- An interesting patent is here -- found working on the patent parsin' graph tool
- The more I glance at it, the more fascinated I become...
- There is no motor! Just electromagnets =)
- Then no need for a stepper motor
- it may be the case that
- The signal coming back is an already processed signal!
- It means the pulse should come from another part of the board... ie another pair of cables.
- Black and white? -> 5 ohm between this pair.. why not?
- What about the other logics?
- It means the pulse should come from another part of the board... ie another pair of cables.
- Next steps: trying and get the reference manual
- Get full echographs boxes on ebay =)
- Plug plugs on headers while running
- Getting a Bard Site Rite III in the mail soon ? ;)

- Article: Impressive Development of a Low-Cost Medical Ultrasound Scanner Using a Monostatic Synthetic Aperture
- I'm a noob at this, but it seems that MFFS uses fixed focus piezos, but MSAS does focusing in the software (hence synthetic aperture) using a piezo of known size. That's an interesting alternative to focused piezos.
- Some other interesting insights, like using "Quality Assurance for UltraSound (QA4US) software" for image quality assessment, or also the architecture they used (an ARM, 14-bit ADC at 12Msps), or even the fact that the piezo is in direct contact with the skin, or a motor using a Voice Coil Motor.

- got an old 10PV, trifreq, to play with. Would be nice to interface it to 32Msps direct!
- chip crisis:
- nothing for the ft600, daugther, lit3-32 and MUXes!
- Doing progress with Jacques
- Getting a new BMV, this time with doppler?
- Too much work ;)
- received first lit3-32 - thanks Silvio and team.
- andrew to help on adaptation
- ft600 support with bogdan
- need to put an io for reset ;)
- Haven't been making boards for a while
- damn chip shortage
- Prototypes (ft600 et max14866) have been delayed far too long
- Let's find a solution soon =)
- Jorge's onto something for the lit3-32 ?
- HV modules: https://omnixie.com/products/nch6300hv-nixie-hv-power-module
- Trying others from aliexpress
- fhttps://www.swyx.io/learn-in-public/
- OS, and maintainers?
- Progressing on the lit3-32 : https://github.com/kelu124/lit3rick/tree/lit3-32/
- History: sharing the original murgen files. Dating from May 4th 2016! Where have these 6 years gone ?
- Starting a substack haha
- OSH : MRI - new stuff
- Newer stuff? Possibly great PMODs to come.
- Still need to debug my existing PMODs FT600 haha
- What about a nice Msi001 Msi2500 PMOD ? New SDR stuff.
- Alternative is CH569 .. great thing. To explore. Maybe for the David friend.
- Work: starting something new! Cool and busy.
- Radicalized - Cory
- https://www.gov.uk/guidance/how-to-document-apis
- Progressing on OSH MRI - fast FPGA + USB3, done, yet to receive the pulse and receive (AFE) parts.
- lit3-32 is going to prod, one batch out.
- un0rick restarts, first batch since a while
- Check out the repo content about wulpus and prisma, some new things happenning.
- Name out soon on an interview, and on a national newspaper?
- Pissed at Slack cutting history of the chat channels
- Wireless probe on the way?
- Moar probes with pyusbus
- Moar to get
- https://ieeexplore.ieee.org/document/9760285 - finger movement recognition
- 10.1109/MIM.2022.9693453 - flexible
=======
- 12 bits ADC
- 150 us acquisition, single channel
- 6 Msps interleaved mode
In 150 us (one line) you will get 6x12x150 = 10800 bits of data. On Wi-Fi speed 54Mb/s it will take 10800/54000000=0.0002s (200us) to send these data.
In practice, we rather see 8Mbit/s, thats 1.2ms to send it.
Lower specs (for dev kit - 1 to 2 image / s OK)
- SPI is 40MHz
- 14 bit
- 2 Msps
- Comm through SPI
- 10ms between lines - 64 lines gives 640ms / image)
- 200us at 2Msps is 400 points is 5600 bits is 700 bytes
- 5600 bits per 10ms is 560,000 bits/s is 70kbytes/s.. should be OK with ESP8266/EMW3165/equivalent ;)
