2019-10-27 Again lit3 progress

  • Dynamic DAC seems better - however some IOs are off.
  • CLosely here, and then some: hardware finetuning (TMP and ADC C at minimum)

2019-10-26 Some lit3 progress

  • 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 ;)
  • @done find the right jekyll theme to leave gitbook
  • see https://help.github.com/en/github/working-with-github-pages/adding-a-theme-to-your-github-pages-site-using-jekyll
  • https://pmarsceill.github.io/just-the-docs/ seem to fit the bill =)

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

  • 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?
  • Next steps: trying and get the reference manual
  • Get full echographs boxes on ebay =)
  • Plug plugs on headers while running

  • 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

Thinking Of An End

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, ..."

2017-05-29 Testing Doj v2

  • Pushing some pics of the devkit 2.0 - note that this config allows pulse transmit. Pulse from the pulser, receiving through the analog front end.. and acquisition managed by the adc and raspberry.
  • Note to self: this config requires a “good” usb power supply. It succeded with a 5V 750mA power supply - but failed from USB.
  • @done Add a documentation server
  • @done Display IP on the OLED.

2017-05-15 Interleaved on RPi.

  • Still about the RPi0 high-speed ADC : if I can’t get above 10Msps due to a memory copy time, I may be able to double the speed by having 2 ADCs interleaved… it’s to test!
  • Some answers for the CMUT stuff.. let’s see if it’s going somewhere !
  • ATL probes connectors are LEMO 18 or 19 pin.

  • 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.

  • Afreen still working on the feather, after contacting the PRUDAQ guys.
  • Get Felix on Slack?
  • Call scheduled with Fouad on tuesday
  • Making progress on 20e214 - control of the probe OK. Display remaining, then CSV saving.
  • Taking more time about the Slack bot: lower priority

2016-08-09 Moving forward

Roughly, all the modules are fine. Emulator is done and tested. Some tests today:

  • Test Analog Processing + ATL3
    • -> https://github.com/kelu124/echomods/blob/master/goblin/2016-08-09.md
  • Test Emulateur de signal + Analog processing
    • -> https://github.com/kelu124/echomods/blob/master/silent/Readme.md

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

2016-07-27 Apres Avignon

Yeayyy! Beagleboard fondation tweeted about Murgen -- that's driving traffic to github =)

High speed acquisition * PRUDAQ

Slow Acquisition * tobo/goblin+cletus+BBB to drive the goblin ADC * tobo/goblin+cletus+hannin to wirelessly stream

I decided the emulation was going to be necessary to avoid playing all the time with piezos. It appears Teensy 3.2 can handle that.

Choice of the servo: * http://www.hobbyking.com/hobbyking/store/__23158__Turnigy_8482_TGY_1267HV_Titanium_BB_DS_MG_Servo_14kg_0_10sec_57g.html * http://www.modmypi.com/electronics/motors-and-robotics/servo-motor-sg92r-micro

  • We use offset remover (suiveur + gain de 2.5), and second op will do amplification, cause envelope output swing is saturated at 1.2-1.3V, We can use 2..2,5 gain to deliver nice and neat 2,6 ..3V input swing for ADC.

2016-04-11 Microcontrollers choices

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

2016-02-13 Release of Gob

  • Lots under way..

      • Required* * : we need to sit with electronics experts to check how Murgen, Tobo, Goblin, and Mira can merge - for a modular board - ideally as easy as possible to use!
  • IDEA: capelec!
  • Need also to push Goblin's files on the repo. Those are made with Eagle, not Altium, so a bit less options, but still interesting to see how to work with those files =)
