Thanks! Thank you for watching!

Nice, do you use any specific holder or you just soldered to the batter directly?

Well, I guess we will probably never know but it could have been both. Thanks for watching!

Sorry, I haven't tested any to recommend.

Thank you! 👍

Thanks. Yes the libraries should work with both. The biggest problem with mine is the finger placement. ideally, the finger should not touch any of the electronics and be attached with a firm and constant pressure so that the values don't jump around on their own.

@@TasteTheCode I experienced the finger touching effect and seem to have mitigated it by applying tape to the PCB so that my finger only touches the sensor. My next challenge with this project is to add an SD card module to log the output (I've done this successfully before with a Temp/Humidity sensor), however, as soon as I include the SD.h library I get an error message in the serial monitor ("SSD1306 allocation failed"). Not sure how to make the SPI device play nicely with the two I2C devices. Any thoughts?

It might but I'm not entirely sure. The chip markings are erased and not readable and there is no mention of the GC9A01 anywhere in the official docs. However, the LGFX helper class in the example code provided has this line inside: lgfx::Panel_GC9A01 _panel_instance;

Thanks!

If you are good at micro soldering then probably yes. I guess it can be combined with a wheel on the side and not bother at all. Also, keep in mind that this has touch so maybe no extra hardware is needed and it can all be controlled with touch.

@@TasteTheCode Thanks for the quick reply, I guess I'll order one and give it a shot :)

♥️ Thanks for watching!

Thanks! No this does not have a speaker nor a microphone. Just a buzzer. I'm not aware of any other with those already in place.

It is just a spacer so the pins on top don't get pushed in when attaching the battery to the drill. The old pack had the last cell in the upright and it pushes on the contacts on top. If you noticed, I have it wrapped in electrical tape so there is no contact on it with the rest of the battery. It is funny cuz the video has 71k views, and you are the first one that noticed it! 👍👍

@TasteTheCode thanks for the quick reply

I think their reasoning is that you will have this battery powered and only use the USB for charging.

Thanks!

Once I got over the versions issues it wasn't that hard. I used one of the meter widgets, adjusted the scale and ranges, and added a label on top. The MQTT code is basically just re-used from their example with my topics added.

It requires some patience but it is doable.

@TasteTheCode I'll try. Wish me luck 😅

Make sure that you can talk to the modules via serial before trying to send data over. If you can't get a response from the module, you probably have a mistake in your wiring. The most common one is not twisting RX and TX.

The app is called Serial USB Terminal. No specific configuration, just the same baud rate as your code and press connect. Keep in mind, that your phone needs to support OTG and that you need an OTG adapter or cable.

That is the role of the BMS.

That's a bold claim my friend. What timestamp are you referring to? If I record everything the videos will be hours long.

OK, you seem to "know a lot" so why don't you teach us all better? And what is this traction sensor anyway?!?

That is an option. This is now working for the past 6 years without any intervention!

Yes, definitely. There are many commercial products that are using these sensors already just for the scenarios that you mentioned.

If a charger is for li-ion batteries, its output voltage will be in multiples of 4.2V. so for example, 4.2V for 1S, 8.4V for 2S, 12.6V for 3S, 16.8 for 4S, etc. The S marking indicates how many cells are connected in series.

@TasteTheCode thank you very much for your help

@TasteTheCode can I use a power adapter from a router or a modem for example??

@TasteTheCode but the chargers for our phones are 9 or 12 volts why is that?

No you can't use a generic charger as there is extra circuitry regulating the voltage in those devices. You must use a charger with the specific voltage that has that regulation circuitry or add that regulation in between yourself.

Thanks! Glad you found it useful.

Thanks. It is a good little module .I guess with some better antennas, it will do much better.

I haven't heard of 5V batteries. Li-ion are 3.7 nominal, 4.2V when fully charged.

No I have not disassembled the receiver but you can look at some obvious screws.

Well apart from taking it out of the device, the trick is to properly charge and use them, not just taking it apart. Also, these are often just thrown on the street. No need to empty garbage containers.

Thanks. It is just an old cable from a USB charger.

👍👍👍

Well they are definitely not making things easier to be repaired.

Hmm that is an interesting take. If I understood correctly, you suggest to limit the current into the battery, right? How did you got the 10 ohm value?

Thanks, I'm glad you liked it!

Hmmm not sure, I guess it might but I can't confirm.

Thansk!

When I did this I think it was on version 13. There were some changes added to BLE in v14 but I don't know exactly what. I think you need to add something to the android manifest manually to enable it.

The sensor will detect you even if you are stationary.

@TasteTheCode tried it. Not really. It's still based on motion, even if tiny one.

You get two values, one if a motion and another if just presence is detected. Even if someone is sleeping in the room, you can know.

Yes you will need to add the mqtt logic in the microcontroller and based on that instruct the module.

I'm not exactly sure what it is or how it is called. It is some sort of silicone glue that keeps components from moving.

Thanks. There is enough play in the entire vise where it is forgiving if it is not that parallel, but using the vise as clamp is a nice suggestion. As for the screw, this is the only thing I could find locally. It is not ideal but will do for now.

@TasteTheCode it's understandable, I noticed it was a general complaint a few others made on the model. An M8 leadscrew wouldn't fit as-is, but I do wonder if it could clamp things without being back-driven and loosening up. As it's a very ubiquitous size of hardware used in many 3d printers.

Yes but I still haven't figured out how to do it. My best idea so far is to add some metal plate at the bottom.

Lora is not intended for such high data transfers. If you split it up, and send it on intervals, I guess it can be done but definitely not what it was designed to do.

@TasteTheCode guess it's wifibroadcast I should try again. Didn't work properly when I tried some months ago.

You mean wifi long range? I haven't tried it but for 500 meters, I think you can also use some directional antennas if you have line of sight.

Yes you can.

No idea. Give it a go. If it doesn't work then try searching for the codes for other manufacturers and standards and try them.

​@@TasteTheCode will be nice to do a video on how to transmit (encode with nec protocol) using esp32 or other microcontroller.

@@TasteTheCode will be interesting to extract the codes directly from the chip of the surround system receiver.
