  • RGB HexMatrix | IOT Clock 2.0

    I'm sorry if it's a dumb question, but the notch in the silkscreen for the LEDs positions in step 3 is pointing to the 5V/Vin pad. Shouldn't it be on the GND pad?

  • Component Tester in a Keychain

    Hi Mr. Baweja!I'm trying to make one.PCBs already ordered and gathered all the components (except the bananas which I'm still looking for at LCSC but don't have the part number).Can you please tell me how to convert the source code to an .ino file so I can use it in Arduino IDE?Thanks!

    In Step 4, the orientation of the leds is with the panel facing you (like seeing the clock when finished) or is seeing the panel from the back side?Thanks!

    Good advise. I've used plexiglas in the 1st one, assembled during the digital logic classes some years ago.

    In the parts list it is mentioned that the plexiglas is 1/8" thick.But what about the mirror's thickness?I'm not getting my coaster fully closed with the mirror that I've got for this.

    I'm ordering the components and the PCBs to give a try to this cool project!Can you please clarify what is the package size or the ref. no. of these components?-10uf 16V electrolitic,-Micro USB port,-WS2812B LEDs (3535, 5050...),-M7 diode, can I use a DO-214A 1N4007?Thanks!

    I will probably use a ESP01 board for this, which does not have D2 (GPIO4) pin. Only GPIO0 and GPIO2.Do you think that it's enough to change the line#define LED_PIN 2to#define LED_PIN 3 or 4 (which corresponds to GPIO0 and GPIO2)?Thanks!Eduardo

    Hi!It's a beautiful project that I'm willing to make. Your instructions seem to be very straightforward in order to anyone can replicate.But can you please clarify if the clock shows 12 or 24h? I'd rather if it is the 24h mode.Thanks!

  • Super Simple RGB WiFi Lamp

    Today I managed to upload the sketch and interface with it from the phone, but after a few minutes of working, the LEDs freeze in one random pattern and do not respond anymore. Tried to unplug the nodemcu from power, reset button, without success.It seems that only re-uploading the sketch results, only to work more 3 or 4 minutes.

The leds are showing no activity at all.I can access to the "Super Simple RGB Wifi Lamp" network either by the pc or the phone, but I'm getting no response in any of the options available in the page.I guess it might be something missing or wrong in the board options.

    Hello!Do you know what could be the reason for the values of temp/humidity on my device are always the same?For example, if it is 26 ºC, the humidity is 26 %if temp = 27, humidity = 27if temp = 20, humidity = 20In other words, the values change but the numbers are always the same for both parameters.I've uploaded the program that is available here, with no modification.Thanks!

    The removal of the R2 resistor indeed have improved the STBY current consumption. I've measured with R2 on the circuit ~45uA, without R2 ~1.3uA.I think that the button issue could also be addressed with this modification:- with a horizontal tact switch (many different sizes available) this is a 6mm which I think should be OK. The pitch of these button's pins is 5mm, so the PCB pads must be increased. Your current PCB design has 2.5mm pitch.As the external key of these buttons is bigger, there's no need to the modification as you instructed, which I think is more "fragile" and less reliable.The button is a little taller and wider, so the STL files for the housing must be modified as well.Please check if you agree and give me some feedback.Cheers!

    Of course, it worked!!!Removing that line (your schematic attached, line in red) that connects the pin #4 of the RTC to the Reset pad of the ICSP, the code was uploaded flawlessly at 1st try.Looking to the images of your finished PCBs, it seems that you did not remove that line, at least in the same point you advised me. Could it be any other mean of bypass this issue?Thank you VERY much for the help!

  • k1200s commented on HariFun's instructable Morphing Digital Clock

    Hello Hari!I think it could be a great improvement/modification to your original code, if you could implement this function:for example, during one hour period the morphing effect will be like yours (as it is in the original sketch), and the next hour the morphing would be like this image, to make the individual segments drop in and fall off of the display, during one hour also.In other words, cyclically change between these two morphing effects that change from one to another hour after hour.What do you think?Best regards,Eduardo

The FT232 is working fine, I've tested it to send another program to an Adafrtuit Huzzah ESP8266 with no problem.I've soldered the 6 pins to the PCB (image attached) and when the sketch is being uploaded, the FT232 led blinks only 1 or 2 times, with no result.I've watched closely to the images that you provided, and saw that some parts are missing. For example, the .1uF near the 4.7uF tantalum is not present.Also, the resistor values seems to be different. In the PCB there are two positions marked with &q…

In the BOM you have only 1x 10k.R5, R6, R7, R8 in your images looks like to be 3.3k (3300) and in the BOM there is 4x 200RCan you please clarify this? Can this be somewhat related to the difficulty in uploading?Thanks!Best wishes!Eduardo

  • Segugio,here are the news.So I've ordered the six IN-14, no problem identifying the anode and the 10 cathodes, set up the circuit in the protoboard and at the moment the two tubes for the seconds indicator were connected, I powered up the circuit.It seems that there could be any error in the code uploaded to the uC don't you think?Please check the video that I've made of these 2 digits, for one minute period:The seconds units (rightmost digit) are OK, counting from 0 to 9 at the correct rate.But the tens seconds don't add +1 at the right moment, in other words, when the units reach 0.I'm using the ATmega328P, I've tried with another one of the same type, with the same behaviour/result.Do you have any clue of what might be wrong?Thanks, and a happy new year!Eduardo

  • Hello!I've made this project and it is almost finished, but I have a question about the power output/current consumption.I have a power meter connected to the input, and it shows (with the LED regulated to the maximum brightness) a current consumption of 2.1A, wich multiplied by the battery voltage (3S LiPo @11,4V) equals to 24W, which is very far from the power announced for the LED that I bought - 100W - and even for the target of this instructable.The step up DC-DC converter is regulated correctly to the 30V output required to feed the LED.Can you please tell me what might be wrong?Thanks!Eduardo
