• Yeayyy finally pushed MS3 for i2s on https://github.com/kelu124/vit3rick/ . Missing the filtering part but that should be fine - thanks Andrew and Bogdan.

• Good progress, stupid capa was in the way on ADC clock. Now acquisitions seem more okay:
• here some good experiment
• @done updates on new pHAT
• remove this capa, remove i2c pullups for the thermometers (that was cost 5$ ! :/ )
• connecter le ice40 au i2c rpi
• pouvoir connecter des ios sur l’uart du rpi
• router les gpio daughter existantes plutôt sur les pins pcm du rpi pour un jour essayer de sortir des données en i2s (GPIO26, 20, 21, 18)
• du coup, mettre possiblement les Pulse controls sur des GPIOs non spécifiques comme GPIO05, 06, 13, 19.
• Niveau header RPi, on peut connecter les SPI_EXT MISO / CS du coup.
• Use 5 first bytes of a read to store the bin number / board ID ?
• Need to make progress on this RTL-SDR for ultrasound ;)

2018-06-25 Or not

• 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.
• @done add the MSAS principles to the un0rick article
• Module

• Wondering if/why I’m slowing down on producing.. Too many users / too many Q&A to answer?
• Adding ultrasound pHAT to listen to and emit ultrasounds (15-25khz)
• @done idea for the ultrasound phat : QuietShark (see https://twitter.com/Dymaxion/status/962385327599112193?s=19 )
• article idea for the un0rick doc: https://gregdavill.com/blog/2018/6/21/boson-camera-project-part-3

• 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?
• Next steps: trying and get the reference manual
• Get full echographs boxes on ebay =)

• Keeping a clear markup of the different functions
• ADC: 10 bit, 65Msps
• 10 bits measures (or pseudo-12 with decimation ? by x3)
• 6 bits remaining by acq: 2 top tour, Pon, Poff, 2 IOs
• Interact
• 2 buttons
  • Manual Trig
  • Select mode
• 4 LEDs
  • Single mode
  • Loop mode
  • Acq (ready: on, data in: flashing)
• Modes:
• Single capture
  • 200us long captures at 65Msps : 208kbits
  • Capacity of close to 35+ captures if needed in RAM
• Loop
  • 130us acq at 24 Msps over 16 bits: 57.6 kbits
  • That's more than 130 lines over a 8000000 bit SRAM
• Transfer back to RPi through SPI
• Variables (to be stored as a header of the file sent back)
• Pon length
• Poff length
• Tdelay length
• Tacq
• RT -- repetition time
• N acq -- number of acquisition
• Implicit:
  • ADC bits used
  • Mode (loop or single)
• Expose:

• 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

2017-07-28 Thinking of an 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:

1. 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.
2. ENDOFYEAR: 15 kits sold, CN not good, MF ongoing (20171217)
3. 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%
4. ENDOFYEAR: still waiting (20171217)
5. 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 =)
6. ENDOFYEAR: Ongoing with Matty (20171217)
7. 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:
8. Listing all docs under YYYYMMDD
9. ENDOFYEAR: Quite happy, having added experiments (20171217)
10. 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 ?
11. 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, ..."

• Still moving in the new flat, getting accustomed to the new job.. and still need to sort the hacking tools in a limited space in the new flat =)
• Interesting competition : Clarius got its approval. Also noted the SONON 300C.
• Having fun with mapping a community using slack. On another repo.
• Published some update on the ML.

Just moved in to the new flat! Exhausting =) Other interesting things: * https://hackaday.io/project/7225-low-cost-x-ray-systems-for-developing-nations

• 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.
