Fast, Portable and Affordable Oscilloscope and Inductance Meter
Building an Automated Dust Collection System
I am afraid it may not work on Uno because of lower specs. but google up, with time people find out new ways
nothing is wrong here, the back speakers only play difference (which is also digitally done by Expanding stereo)
in my setup rear speakers are very close to sitting, but still the sound seems to be coming from front location. No scientist here, but stereo seems expanded not reduced.
I have done this, and absolutely awesome, beats 5.1 straight away , where center stage is always a problem, Now I am making 5.1 amp with digital haffler matrix (with option to by pass it )
yours PT2258 worked out of box, I am banging my head here both Ics i have dont respond to i2c scanner. i tried and dosent work with code either
@Jacobthe whole purpose of diy is not saving cost (although it can be a big additional benefit) The feeling that you made something can worth much more. On ali express its for $3.5. I had same feeling when I made my project for 40ish dollar which is available on aliexpress for 5 :P but I made customized and its mine.a good readhttps://www.psychologytoday.com/blog/make-your-mind/201209/the-ikea-effect-why-we-cherish-things-we-build
I made it too, I have checked and read that software was work in progress when original author went silent, its still in development software so there are many issues, One website claims that the resistance is the worst in this one, it can only be used for transistor testing (which they said is good) and get and idea of capacitance.Inductance didnt worked for me either. Hanged on Mosfets
sadness not working for me, used correct settings, but still seconds lines blank like interlacing efect#define SSD1306_128_64// #define SSD1306_128_32// #define SSD1306_96_16
i read somewhere this is issue of buffering, check adafruit forums.
ARDUINO - SPFD5408 TFT LCD 2.4 TEMP and HUMIDiTY Monitor. Fahrenheit & Celsius!
no doubt about that, 595 costs around 8/Pkr while I2C 64/Pkr.
I have tried it in past project, it works great, Latest development is you can get I2C board cheaply with LCD that takes care of hassle (just sharing info)
Nodemcu devkit (esp8266) display temperature on an i2c lcd display
when I had that problem, i blew with blower from drain side :P worked like charm (not recommending this method at all)
I have tried it and later used in a project. works like charm.
this is not paint, only for stained looks. for protection apply varnish etc above this (after its dried) ~ with love from Pakistan ~
is it only for me or the images on bottom of article are missing
neat trick @copyrightgood product, infact I am making one too for my own home :D just ordered the ultrasonic senor
this fear for heat up electronics felt like Y2K bug, remember those, got fixed by simple update. this image is not of something getting hot, and if someone is trying to waterproof electronics thats giving out that much wattage, perhaps he does need to learn by hard way :P
good one, I did something similar to my HEATING up resistor! :P I realize what you did and why. people are so much worried about heat same as they got worried about grounding in wiring, which is alien concept in asia :P so rock on. Although do give attention to things pointed out but take too much pressure. With love from Pakistan
* but dont take too much pressure
epoxy idea is also good
Monitor your Inverter Online/Test your Home Inverter
that box !!!!! lovely
If I am correct, these smaller speakers are magnetically shielded (magents are covered in metal enclosure) so they can be used near TV and PC.
lovely name :) PiFi

Great job, congrats, would love to see it working on pc
I wish i found this earlier. I made something like this, but perhaps designed poor, because i was worried voltage loss in of 25 meter wire (LAN Cable), So after the failed experiment with transistors, I have switched to arduino and to justify my path I also added rgb leds :P with abilty to change color of filled / empty indicators, not to mention buzzers on low level and little buzz for over flow. http://inoace.com/blog/water-tank-level/
isnt the reset resistor supposed to be on pin 1 of atmega, not after cap. Plz correct , it may misguide people
download what, copy the code. rightclick save mage
only supply voltage and test resistor values if they work
It will cause electrolysis and the + will disintegrate. (done it) i have this idea to periodically scan sensors for change in level. like after 10 20 sec
always give full details when asking question, and images of your setup, there can be a million thing wrong.
Thankyou for sharing info, didnt knew about paint/alcohal ink.I have managed to work with toner transfer > hot salt water electrolysis with 12v battery > vinegar/peroxide to remove remaining copper dust.
Arduino on a Breadboard with a FT232RL
Here are my observations from living in Pakistan:1. either its ,more diluted vinegar or hydrogen per oxide. the process is NOT 10 - 20 minutes long, but takes hours. which in result causes poor tracks as toner transferred plastic begin to dissolve or drop off. Conclusion; Poor method for my usage.2. Better: use electrolysis in salt water solution. BUT it leaves dust like structure behind, perhaps not fully etched. 3. BEST OF BOTH WORLDS. I used electrolysis to remove access copper from pcb than used vinegar method (1) to remove the little dust like structures. Worked like charm.
expensive and not easily available at some places.
150gm glossy paper works like charm too.
I have noticed , this is only good where the copper is single plane, what about parts separated. Also it leaves copper dust like structure on board (not all etched away)I experimented and found these steps to work for me:I etched pcb in 2 steps,Step 1: etch away all major copper via salt water electrolysis. Step 2: etch remaining copper dust via hot Vinegar+hydrogen per oxide + salt water

Thankyou for sharing library, I got this oled, 128x32 (while the vendor claimed to be 128x64) confirmed with both adafruit and U8 library. it has scanline type effect. guess its because of lower resolution
