    I certainly continued your tradition of 'mucking about' even with every single solution pre-provided. So much fun! Now I too have a handy ammeter. Thank you very much Julian and as always thank you for the entertaining video. Cheers.

      Yes I have been doing that for years it works well just make sure your iron is hot and tined well then when you see the solder melt bang it down and the pin or wire will come out and a bit of practice and it works its all in the timing

    This video encouraged me to try Full Page Buffer mode in u8g2. Despite the RAM being used, it is really very easy to port stuff made with U8X8 to U8g2 in full buffer mode. My weather datalogger project is now running happily on a Nokia 3110 display (I used a small OLED before, but that ate too much power). A 300mAh lipo should now last for at least a week (ideally calculated 9 days).

  • @dalenassar9152
    @dalenassar9152 6 ปีที่แล้ว

    You should add a short bit of stripped (hollow) wire insulation (fallen on your table) over those 'closely' placed/crossed bare wires. Another tip I learned over the years: When soldering something like an 8-pin DIP socket onto a PCB, first solder diagonal pines (ie pins 1 & 5) than while putting slight pressure on the top of the socket, wet the solder at one of those diagonals--you will hear a slight 'click' as the pin fully jumps into the hole--repeat for the other diagonal. Now solder the remaining pins and all will be flush! You may want to slightly re-wet the diagonals. This works for all size DIPs including the big 40-pinners as well as with SIPs!

    INA219 Specs (26V ±3.2A).
    As of 2018 Adafruit recommends the Metro Mini 328 instead of the Pro Mini or Trinket boards due to FTDI bootloader, driver issues, and other issues. Metro Mini costs less than purchasing both the Pro Mini & CP2012 (required to program a Pro Mini). So if you were to replicate this project in 2019 you'd want a Metro Mini, INA219, and 128X32 OLED. It would be more powerful, more efficient, and actually cost a few dollars less than in 2017. :)
    There is an INA169 which has much higher range but after research, that one is analog only to be measured with a multimeter or separate data logger, it does not have I2C communication which is needed in this project. INA219 is still best for this project. The Metro Mini can communicate through I2C or SPI so it's compatible with the INA219.
    In the code you can set the screen to flip between displaying voltage and amperage. You only show it monitoring amperage in this video but it will do voltage too. You did actually show that in your other video (I paused to go watch it). Great job with the info card links. You make quality content. Very easy to watch and follow along. I was going to comment about improving the code for mA, A, and watts but I found you have another video where you address that. :) th-cam.com/video/zvcTUMBGO24/w-d-xo.html
    Awesome monitor for little projects. Will fit into a tiny project box. I actually don't have one of these but because of your video I'll probably pick one up to play with. Thanks for the great video!

  • @MegaScott
    @MegaScott 2 ปีที่แล้ว

    Right. My experience with the INA219 pre-built boards is that the 0.1ohm shunt resistor is not exact and varies allot with temperature. Also, some noise can be filtered with a .1m capacitor across the shunt. These boards seem to work well as intended to get you up and running in a short amount of time. The Max rated current you can measure with this 0.1m resistor is only 3.2A, but you can reduce the shunt resistance to get a bigger current reading, of course some modification to the INA219 library is required, or you can scale the reading from the sensor using a bit of math, and if you're feeling a bit more ambitious you can make a routine to scale the current based on the temperature of the Shunt resistor. Adafruit has a good write-up about this sensor, but probably this kind of accuracy is probably not required for most people. Good vidjeo. Love that there is an actual voice Behind the Mic versus some kind of computer driven synthesis . I have done some looking around, and if you want to make your own board with the INA219 chip it comes in two sizes, the very small SOT-23-8 and the SIOC-8, the SOIC-8 is more widely available and for the hobbyist, much easier to solder onto your own board as compared to the SOT-23. Thanks!

  • @JamesFraley
    @JamesFraley 4 ปีที่แล้ว

    Great video. I would love to see you turn this into a complete process. IE: put insulation around the wires, put it into a case and maybe eve order a PCB and make it a more permanent build.

  • @Hasitier
    @Hasitier 7 ปีที่แล้ว

    Great to know that the ina219 also works as a stand alone current Sensor. I always thought that you need to wire up the voltage measurement also to get it running. If you ask why is that a Problem for me: well it can only measure up to 26V. That might be a Bit low for some applications like a Self made bench power supply.

    You dont even need that right angled header for programming ...
    Your programmer fits perfectly. Even the Layout is the same

    • @pfeerick
      @pfeerick 7 ปีที่แล้ว

      Not quite... the 5V and GND wires are crossed over... you can see the blue wire is on the top pin on the USB to serial, but the purple one is on the top on the Arduino. Otherwise it would have been perfect, and the right-angle pin header could have been replaced with a right angle female socket for direct plug-in!

    @MarkHopewell 2 ปีที่แล้ว

    I plan to use this device to sense a current signal transmitted from a wind vain sensor so as to be able to transmit the converted current values via I2C to an Arduino Nano in my weather station project. Fingers crossed the device is able to sense currents down to 4mA!

    • @pfeerick
      @pfeerick 7 ปีที่แล้ว +2

      Yeah, there is no averaging or multiple sampling in the code whatsoever, so you only get the instantaneous reading from the INS219, rather than a more sane averaged reading. Doing something like five or 10 samples and averaging them before display should smooth things about a bit, and can be done without adding too much overhead time. However, that is outside the scope of a 15 minute project... especially when you need to explain how to calculate running averages in code, etc ;)

    Nice work and great video. Maybe its possible to expand on this circuit a bit further. Objective: Power a small AC Ammeter display using only 120vac Source being measured. So module would have 120vac IN as the load, and show the AC current on a display without any external DC power supply. The Display would need to fit an area that is .50in high by 1in wide. Depth of entire circuit around .50 inch.

    Hello, I have a question regarding the INA219. I am connecting a power supply of 24 and a motor load connected to it. The motor could run in forwarding and backward directions by supplying +24 and -24 simultaneously. The motor draws 400 mA currents on both voltages. The question is, INA219 can work on positive voltage but would it also support a negative voltage of 24 volts?

    Why no shrinkwrap over one of the two leads at each intersection? Sure it would had looked weird but it would had prevented the need to re-spread those connections.

I want that along the bottom of the mixer. On the top of the mixer's audio meter bridge, I want to add color displays above each channels dB meter that display each channels spectrum analysis. Please help me with some ideas how to start. I need either one interface to control each thing, or several really small controllers I can install inside the mixer with being to obtrusive. I thank you in advance. These additions to my console would increase it's value and make it have similar features to a high end console.

    Hi !! Great video. Quick Q. When you use the CP2102 device to upload the program - do you just use the standard "upload" button? Or do you use the "Upload using programmer" function - and if so - what do you set the programmer to?

    • @tin2001
      @tin2001 7 ปีที่แล้ว

      Donald Filbert
      Not sure what he does, but Arduino's IDE triggers the bootloader mode by setting DTR on the serial port. So adapters that don't implement DTR (like the ones I use) don't automatically put the Arduino into bootloader.
      The trick with these adapters is to hold reset, click the upload button, wait for it to say "uploading...." in the status bar, then release the reset button. Since 90% of the time I want to be pressing a button or connecting something immediately after, I don't mind the extra button press.

      can you not just take lots of photos in quick succession with constant lighting over several drops and hope to get 1 good shot by chance?
      I don't know the photography terms. I assume you have a high end camera that is capable of doing this.

      yes, you can take my camera will take 7 shot a sec as long as my shutter speed allows it. BUT I also need the flash to fire at the same speed, if the power is very low it might just keep up. BUT it will not allow milliseconds adjustments I have done some free hand see here.www.flickr.com/photos/chaz_madge/21089376996/in/dateposted/

      can't floodlight and forget about flash?

      in a word NO your exposure is using the flash to set the shutter speed, in that the flash speed is much shorter then your camera shutter can be fastest is 1/8000 of a second whereas a flashlight you can get as fast as 1/38500 (not studio light they are slower) so you see it's all about freezing at speed.
