    HackerBox 0040: PIC of Destiny

    The status light routinely turns off for me as well. That seems to be normal. My PICkit3 is working fine. Something else must be wrong.

    So, I've gotten past almost all the hurdles but the final goal still eludes me. Has anyone gotten the GPS circuit to work properly? I've been successful using the PIKkit3 to program my chips after figuring out how to correctly set the power target voltage. I've gotten the LCD to display both lines after learning from HunnyDob that D3 has to be pulled up to 5V rather than being grounded. Why is that? Why do all the instructions show that this pin is grounded when it just doesn't work that way? This makes me wonder if there isn't something else going on related to the hardware that came with the kit. Now I'm stuck on the GPS project. I leaned that X8C global options have to be set to C Standard C90 (whatever that means) before it will compile so that's all good now. I've successfully load...

I've successfully loaded the code into the chip and it displays both lines of the opening LCD screen. But that's it. It never progresses further. The GPS module is powered and the green light flashes telling me that GPS data is being received. The TX output line from the GPS module is connected properly to the RX input port on the PIC. But nothing is happening. No further information comes up on the LCD. It's just stuck on the first intro screen. What gives? Any ideas?

    The pull up resistor make no difference for me. I suspect it's not an issue.

    It's probably not the PIC chip. If the circuit is behaving erratically then make sure you have capacitors placed across VCC and VDD (+ and -) of the power supply. Transients in the supply rail often cause trouble. The capacitors help to smooth them out. Also, the cheep Chinesium breadboard may be at fault. If the capacitors don't help then try rewiring the circuit using different holes.

    I totally agree! The comments in the Instructables sections are often very helpful. The next best source is the Reddit HackerBoxes site and the least useful is the Discord site which is mostly just chatter among a few people who don't have much of anything useful to say. Also, if all else fails be sure to contact HackerBoxes support directly. They really are very helpful.

    In your photo I can't see clearly where you have the LED (+) anode pin placed. Is it on PIC pin 2? That would be the correct output pin so make sure that the anode (+) side of the LED (longer pin) is connected to PIC pin 2 and the cathode (-) side (shorter pin) is connected to ground. Otherwise...no blinky.

    Don't forget to check off the "Power target circuit from PICkit 3" box when you set the voltage. That was tripping me up until I finally checked it off. After that I was good to go.

    The weather icon eventually showed up too. The weather data seems to update rather too slowly. Maybe there's a way to modify the code to update more frequently.

    Could be a loose connection. I had the same problem. I couldn't figure out what was wrong. So in frustration I took a break. Then I came back and I pulled all the wires and started from scratch. I made absolutely certain that every jumper was firmly and correctly inserted. It started up just fine after that. It's working like a charm now!

    I got the remix code up and running. It's very colorful and full of extra information. I like it! It's interesting and a little disturbing that it almost immediately and automatically connected to my WiFi without any need to run through the set up with my SSID and password. Maybe the ESP-12E dev board saved that information from the previous set up of HariFun's code? Also, there doesn't seem to be a way to enter my geographic location. On OpenWeatherMap.org there are three different weather stations listed under my town and country each in a different region. Somehow it seems to be defaulting to the weather station data for my area. Maybe my geographic location is already associated with my assigned API number? The weather icons don't seem to be working. Otherwise, great job! Thank you!

  • ESP8266 Internet Clock With Weather Update & Many More (No RTC)

    But don't get me wrong, I still appreciate the effort that the author has put into this tutorial. I am learning from it and I'm going to give it a try.

    StrangeRand makes a good point. If you look at the code for internet-clock.ino it would appear that the NTP server is not used. Rather it seems to use Google as the time server. So, here we have a tutorial that goes into detail about using the NTP time server but the final code uses an entirely different method. I agree...weird.

  • ESP8266 Internet Clock With Weather Update & Many More (No RTC)

    I'm not able to get your code to compile. I was able to find the nonstandard libraries and install them into my Arduino IDE but it would be helpful if you were to include links to those libraries in your instructions. Even with all the required libraries installed I still can't get the sketches to fully compile. And yes, I'm sure that I selected the correct board. None the less, the compiler hitches up on the ArduinoJson and ArduinoOTA classes. I suspect that this may have something to do with conflicts between versions of one or more of the libraries and/or board packages that I have installed that probably don't match the versions that you may have used. I just can't seem to resolve it. Any ideas?

    Has anyone had trouble using the WeMos NodeMCU working with the LED strip? I'm using MacOSX 10.13.5 with Arduino IDE version 1.8.3. In order to get the NodeMCU to work with the FastLED examples I've found that only an older version of the ESP8266 Arduino core works. Only version 2.0.0 works and it runs at a very fast rate. The current board core version 2.3.0 is no good at all. I've also tested the code on a standard Arduino Uno board and everything works perfectly.

  • Make Your Own Graphical Weather Station

    Thanks Richard. I've recently used one of the inexpensive PCB manufactures. It's pretty easy. And the prices are crazy cheap. They can do it far more cheaply and much more professionally then I can. The only downside is that it can take several weeks to get the boards. You can choose a faster delivery but then the prices go way up. I don't know if I'll get to this project anytime soon. I have a huge backlog of things waiting for me to work on. But thanks for posting the files!

    HACKERBOX 0028: JamBox

    How do I change the frequency of the tones in the HB28Sequencer.ino sketch? The tones sound pretty monotonous. I tried changing the second arguments in the loadwavetable() function, thinking that might change the frequency of the tones. But no, the frequencies all seem to remain the same, only the timbre changes. It sounds like the only thing that's changing is the duty cycle of the same monotonous tone. Does anyone know how to modify the code so that it generates a set of distinct audio frequencies?????

    I don't know. It may be that my understanding is too limited. My idea of a wavetable is that there would be an array of digital data used to define a waveform that the DAC would convert into an analog signal. Maybe be wavetables come already built into the ESP32 firmware? Or maybe there should have been a file appended to the Arduino code that contains the wavetable data but it was inadvertently omitted? Or maybe the whole thing is working exactly as intended and I just need to tweak the code until it's the way I like it.

    Oh wait...never mind. Now I get it. The code actually generates the wavetables. Thank you Make Magazine and grtyvr for helping me to understand https://www.youtube.com/watch?v=LnwmktiJXZg&t=2192s

    I can't seem to get your code to compile. There are errors that reference the FIR library. I'm not so sure that I have the right library installed. I downloaded one for Arduino which I located on a google search but it doesn't seem to pan out. I'm guessing that you are using the FIR library to smooth out the very noisy signal that this circuit is producing. Maybe you could provide a link to the library that you used? I'd love to try it out!

    I finally figured out how to get LiveCamTest to work with Processing and use the Hackerboxes external cam within the Mac OSX system (MacBook Pro). The sketch was defaulting to the MacBook Pro's FaceTime HD camera. I looked at the parameters for the Capture module and I realized I needed to add two additional arguments to get it to use the external camera:video = new Capture(this, 640/2, 480/2, "USB2.0 WebCamera", 30 );The two extra arguments are needed for selecting the camera name and the frame rate.I found the name of the external cam by using Webcamoid. I picked a frame rate of 30 but 15 works as well.

  • "Hurry, Doctor!" an Arduino Powered Operation Style Electronic Board Game

    Great project. I've pretty much everything I need right now except for the lego parts. I've scrolled through your instructions several times top to bottom and it seems that you've kind of dodged any details regarding the little pieces that go into the compartments that make up the game. Seemingly a small detail but the game is pretty well useless without them. So I'm wondering, can you provide a little more info about what the individual game pieces are? Are they all lego parts or what?

    One of the things that I thought was wonderful about the project was that it didn't require access to a 3D printer. Too good to be true. I do know someone who has a printer but he lives about 667 miles from me. I guess I could send him the files and he could then send the objects to me after printing. That is an option although not ideal. One day I'll get my own printer I suppose. But anyway, I'd be very grateful if you would be kind enough to send the files to me. Also, photos of the Lego accessories would be helpful. I'll try to track those down before resorting to the printer. Cheers!

    Check to see if the LED is reversed. I didn't see black and white cheese (whatever that is) but the screen came on briefly, solid white, and then black. Like you I thought maybe something was wrong with my surface mount components but they were looking good. So I checked the LED and I suspected that something was wrong. I reversed the leads and everything sprung into life!

    Got it.

    Same thing happened to me. I had it in mind that the flat side of the LED was the cathode (-) side. So that's how I soldered it in place. WRONG! Brief flash of the OLED screen then nothing. So I looked at the LED more closely. The LED die is usually attached to the anvil and that's the true cathode side. If you look closely you can see that through the lens. So yeah I had it backwards. I reversed the LED and Viola! It's alive! Working as advertised!

I had it backwards and it didn't work. Note that when the card is inserted correctly then the red led will go from fast flash rate to a slow flashing rate. Also, I found that I needed to insert my full phone number into the code. 1 followed by area code followed by my number (for USA numbers). Nothing less works. All is working now. I tried the software serial version and the Seed-Studio GPRS arduino codes and both work well. Love it!
