    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!

    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

    Thanks for the reply and the suggestions that you've made!But even with a 3rd PCB finished today, it is all the same with the previous two.In this last board, the CTS pin was not connected, TX and RX swapped a few times, with no positive result in uploading the main code. Bootloader via ISP pins was ok with no problem at first try.The testing was made with 3 different FT232 devices, in 3 different laptops with different OS: Windows 10, Windows 8.1 and Windows 7.All the electric connections were tested and there are no cold solders or shorts:- board componentes between each other;- board pins to the microcontroller:GND pin -> #3, #5 and #21CTS pin -> not connectedVCC pin -> #4, #6 and #18TX pin -> #30RX pin -> #31DTR pin -> .1uF, the other pin of the capacitor to #29 (R...

How much might that cost? I'm from Portugal.Thanks again for the help.

    Hi Sverd!I'm almost finishing this great Instructable.Right in the last step before enclosing it in the case, I'm having difficulties.The bootloader was uploaded ok, using an arduino Uno and the ICSP pads on the watch PCB.But I'm not being able to upload the sketch, using an FT232 board. 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 ...

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 "10k" and you placed 51k (5102?). 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

    Simple User-adjustable DIY Nixie Clock

    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

    Simple User-adjustable DIY Nixie Clock

    Hello Ruiz,I'm interested in the improvements that you've made, but the code in Github seems that is not working correctly. The "Verify" button in the IDE shows some errors.I've installed already the Bounce and the Timer libraries.Also, could you please send me the schematic in higher resolution? My email falcon2000x@gmail.comThanks! Happy new year!

    Simple User-adjustable DIY Nixie Clock

    Hi!I'm looking forward to make this project with Nixie tubes like yours (vertical style) rather than the ones that Andrea used in the instructable (horizontal).Can you please tell me if the pinout of the IN-14 is the same of the IN-4 used in this project?I suppose that there are 11 pins in total, 1 anode + 10 cathodes for each tube.And the neon separators, do they use the same 180V of the main digits tubes?Thanks!Eduardo

    For sure!I think this photo is more straightforward, as it shows yellow the esp8266 pins, and green on both connectors the pins that connect each other.Thanks!

    Hello Jon!Congratulations for the excelent Instructable!I've made it and it's working.But can you help me in this question? Last Sunday began the DST in my region, now it is GMT +1. I've tried to change the line #52 of the sketch where the offset of the GMT is adjusted, as follows:const int hours_Offset_From_GMT = 0;toconst int hours_Offset_From_GMT = +1;but the displayed time it's always the same using "0" or "+1"Do you know where it might be the problem?Thanks, best wishes,Eduardo

    Make a 1000w Equiv. LED Flashlight!

    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
