Tell us about yourself!
If you go to that same link there should be two .jpg files with the wiring. One thing to make sure on any of the Adafruit boards running CircuityPython you want to make sure you have the Libraries copied onto the drive. There is single Lib folder that needs to be copied and pasted. More details on that are here. https://learn.adafruit.com/welcome-to-circuitpytho...
There was a note in the instructions mentioning that sound was not yet implemented in the code just yet. Hopefully soon in the future.
One other thing to note on the Neopixel Ring, You can daisy chain them, so DO = Digital Out and DI - Digital In.
I just wanted to mention if you have subscribed to earlier hackerboxes, Box #25 I know and one other one had these battery holders in them so if you had those boxes you might have left over parts possibly. :)
That's a bummer you have a missing part. All you need to do is contact them at this email address - firstname.lastname@example.org
These little books are great! :)
Here is a video of the Neopixel ring on the ItsyBitsy M4 running CircuitPython.https://gardnertech-my.sharepoint.com/:v:/p/tim/EZsSncWV1FhDiHIh2gC4XYIBLGUDVctyVOC-eYjKacum3Q?e=nIugar
Here is a video of the NeoPixel ring running on the ItsyBitsy M4 using CP.
I have this little notebook!
This is a great box. I love CircuitPython and all of the different Adafruit boards. You can even run it on the raspberry Pi thanks to their Blinka library.
I hooked up the fingerprint reader today. Super cool! Very easy to use and will work well in any access control project or anything where you need to track identity. I solder the pins on the up side of the nano board and 3d printed a holder. I need to tweak a bit.
I made the spinner. Now onto the fingerprint reader. Thank goodness for magnification and a benchtop power supply to double-check the polarity on the LEDs. Surface mount soldering wearing glasses and partially colorblind can be a bit tedious.
i made the integrated unit. With some left over parts still and other stuff I have I think I will build the seperate ones asd well. Will have to solder up the signal generator in the next day or so. Great Box! :)
Thats cool! Thanks for sharing it.
You are right. There's anotherboard I was thinking of. It was a bit tricky.
I threw together a 3D stand/bracket for mounting the LED matrix. It's not perfect but it works. Feel free to download it here and alter the design to suit your needs.https://1drv.ms/u/s!AlJEBzxLFQ7zmeohfQnjctBeNV9n7w
Do you have the PxMatrix Library library installed? That could be it and it is sometimes neccessary to restart the Arduino IDE after adding libraries even though it doesnt tell you too.
So I upgraded my pool thermometer that I made using the Arduino Nano and OLED from box # 35. Works great and much easier to see!
These board you sometimes have to press the BOOT button right when it begins the download after compiling. Sometimes it takes several tries to get the timing down. This puts the board in programming mode.
This is a great box. The displau is awesome! It will actually pair well with last month's box (#35) using the LED Matrix in place of the OLED display.
Pool Thermometer :)
Oddly enough I had the same problem on my desktop PC but not on my laptop. I upgraded both to the latest IDE but still had the same problem. Strange....
Here are a few pics... One with the text color inverted. It's harder to read.
If you are playing around with the MQ-3 Sensor I would highly recommend reading about the characteristics. https://jenslabs.com/2013/03/18/measured-sensor-ch...I have found the times for it to reset/stabalize to be somewhat accurate. I am going to get a TGS822 and try the Ketone sensing project with it.
Did you first install the SSD1306 Library and if so, how did you go about installing it? Sometimes you need to restart the IDE after installing libraries.
I am using Windows 10. I followed the instruction in the guide here -> https://www.rtl-sdr.com/rtl-sdr-quick-start-guide/Pay very close attention to steps 7 thru 11 regarding the driver.Further down below those steps are some additional troubleshooting steps.
Joe, after going back and reading it again myself, I see right at the beginning in bold lettering that XP and Vista are not compatible. :(
I'm up and running with the RTL-SDR using AirSpy. The quick-start quide is spot on. I'm listening to an old familiar freind on NFM 162.390. If you are in HackerBoxes territory you know who that is! ;) Now on to GNURadio... Soldering tommorow...
I haven't tried it with my eyes closed. I was able to open a different padlock with a similar lock mechanism I have on a toolbox and got it picked open.
I'm not usually a picky person, but, the lock was easy to pick. LoL! Great box! ;)
Great box this month! Ironically I was thinking I needed to put a little kit like this together. Working in IT I am often times wearing the network engineer hat and this is the perfect compliment to Wireshark. Got the OpenWRT loaded. I wonder if DD-WRT will work on it? I have loaded that on many routers and just explodes the features and capabilites of a cheap router. More like what you would pay hundreds of dollas for.
So here's what I have which should satisfy my needs on most days. I also have a little Radio Shack mini multi-meter not shown in the pictures which will fit in as well. I have a few feet of solder wrapped in the spool of solder wick. Screwdrivers, small cutters and needle nose, pry tool, zip ties, USB cable and wall-wart as well as a USB power meter and 8GB flash drive. Somehow, someway, I am gonna fit a roll of duct tape in this thing!
That's what I did too. Worked like a charm. :)
The Enigma Machine is built. Now just have to work on the code.
I'm half way through building the Enigma Machine. Just have to get the keypad on and tweak a few things.
Which OS are you running? If you are using Windows you want to make sure that ST-LINK shows up in the Device Manager. It will be under Universal Serial Bus Devices. Also, try to avoid using a USB extension cable if possible. It's always a good idea to load the latest version of the Arduino IDE. In some cases I have had issues and simply restarting the IDE wasn't good enough. It required a reboot of the computer too.
Got it done... Seems to work just fine. Great Box! :)
Just taking inventory of parts and due to colorblindness I have to ohm my resistors with a meter. Missing the 2.2M for R7
Disregard .... I have them. Just missed them somehow. Too much clutter on the desk. ;)
Now onto building the antenna.....
Here's the sketches I used if they can be of use to anyone else.https://github.com/TimGTech/Wemos_OLED_Display
Almost forgot... Here's a great free WiFi survey tool that use on a routine basis. Free for Windows. Works great. http://nutsaboutnets.com/netsurveyor-wifi-scanner/
HackerBox 0023: Digital Airwaves
I loaded an example sketch and had to do some playing around and tweaking to get things lined up on the screen ( hat tip to neogeek on that one ). Then found some wifi scanner code and got to tweaking it and got working. Yeah! :)
These micro:bits are great. A lot of fun! If you follow the music and sound module link on the microbit python page it says to use a speaker and do not attempt to use a piezo buzzer. They work just fine.
After installing I unplugged from the USB and rebooted. Plugged back in USB and the com port appeared.
Maybe try using jumper wired or a stacking header if you have one to connect the SD module to the breadboard. I was having issues and that was the fix. See my previous post about it with a few pics.
If you have issues with your SD card module try using male/female jumper wires to connect it or a stacking header if you happen to have one. I was having issues with mine and discovered that it wasn't making a good connection on the breadboard. So functionality was hit and miss. After using a stacking header to connect it, it works like a charm every time. The hearder pins on the SD module are a tad short for plugging into a breadboard directly.
I plugged in the GPS module and Windows 10 has a USB driver for it so it did not show up as a COM port. So I installed the Ublox U-Center and selected the Ublox driver instead of the Windows driver and now have it showing up with a COM port. So now it reads in the Arduino monitor. Works fine in U-Center too. Just can do both at once. Just sharing in case anyone else runs into this.
On a side note - The ruler was worth the cost of the box alone! It's bad to the bone! :)
HackerBoxes 0021: Hacker Tracker
UPDATE - Now that I've had my Dunkin Donuts this morning... I headed ovet to the HXB Reddit page and found my problem.... Just needed to update my Arduino to the latest version. All working good now!"Never a duh moment around here" :)
Just loaded the HB020_Badge_A firmware and getting "not declared in this scope" errors on...'mutebutton''RainbowLEDcycle''wifiScan2LCD'...and on down the line.Did this code work as-is for everyone else?
That pretty sweet.
Got mine all soldered up and working. This tester is going to come in very handy! Great box this month. Now on to PyroEDU...
Microscope.... No ProblemSoldering SMT,,,, No ProblemDropping an SMT component on the carpet.... PROBLEM!
I got this response from Ryan @ Hologram as the proposed fix. I have been so busy I have not had a chance to try it myself. I hope to give it a whirl within the next few days and will post my results back here.Hi @TimGTechFor some reason the SIM800 sent requires a SMS config. This blog post explains the steps http://www.smssolutions.net/tutorials/gsm/sendsmsat/ Basically run this command: AT+CSMP=17,167,0,16 . The post explains things in more detail.If you could try this, then we can go from there. @benstrThanks,Ryan
Sounds like we have the same issue. I posted in the Hologram forum. Any feedback or resolution I get from there I will post back here.
Thank Ben. I have a post on the Hologram Community forum. Hopefully it will get worked out. I'm hoping to get it working. At least to be able to send SMS messages.
Hi BenAT+COPS=? = +COPS: (2,"T-Mobile USA","TMO","310260"),,(0-4),(0-2)So I guess maybe it is connecting?
OK this is driving me nutz!!! It's not connecting to the cellular network it seems. I activated the SIM ok. I have everything wired properly. I tripple checked wiring and code. Then I ate a Nutty Bar and checked it again! AT command responds "OK"But - AT+CREG? = 0. I assume that's meaning its not connected. The Hologram Dashboard doesn't show any data either.
AT+COPS? = 0
I have my ESP32 up and running. I opted to go the Arduino IDE route being I already had it and Python loaded and ready to go. BTW - If anyone is having any troubles getting started, the Sparkfun hookup guide is great too. Although its for their version, it's basically the same setup process.https://learn.sparkfun.com/tutorials/esp32-thing-h...I ran the WiFiScan example and that detected my SSID's ok. However, the Basic Client example would not connect to either of my AP's (Verizon Wireless Router and a Ubiquity AP). The WiFiMulti.addAP used in the BasicClient example must not like them But I kicked on the HotSpot on my cell phone and it connected to it just fine. I used one of the others that uses WiFi.begin to connect to the AP's and they all connect fine using it.Now onto gettin...

Hey i'm trying this out. When I copy and past the Web code and save as an html file it just displays the same code in the browser when I open it. Also, the code for the Particle Photon it says in your instructions to connect to D0 but the code has A0, Is that right?
Hi!My name is XOR. But you can call me AND OR NOR. But NOT ever NAND!Cool box this month! :)
I got mine up and running with no problem at first until it came to the wi-fi. After reading through the suggestions I was able to get connected stetting the driver to "nl80211". I set it to "none" and it didn't work. But afterwards I set me locale correctly so maybe that was part of the problem to begin with.
Yes definitely in this case I'm sure it is. Was just sharing that bit I knew from my days installing car stereos and mobile electronics. As long as they don't put DCC we will be alright! :)
Thanks Slackmaster! That helps a lot.
ACC is typically used in the automotive industry and I think means ACCessory circuit. When you insert key into ignition switch and turn it to the left (backwards) you are turning on the ACC circuit. It will allow you to operate radio, windows and other accessories, but it does not turn on fuel pump and other engine controls. It saves battery for when you need to operate vehicle components without engine being on.
Jasper,You were close. I figured I must have had it backwards but I double checked several times and I had it correct. After closer examination I discovered the chip was on backwards. Actually the whole socket was soldered on the board backwards. The chip was in the socket the correct way. I turned it around and was good to go. Then I discovered the cr2031 battery was dead. I put in a new one and I am in business! Thanks for tip to get me going!
On the RTC I keep getting RTC Sync Failed! and RTC Set Failed! Anyone have any ideas?
This hackerbox was jam packed full of good stuff. I put the clock together. One piece of the plastic case had a small crack the acrylic but no big deal. It all went together smooth. If anyone has any more info on the modes and setting that would be great. Mine has to have two different times and the alarm time. I'm trying to figure out what the two times are, can you switch between 12hr/14hr, and change the temp from Celsius to Fahrenheit. Now I just need a backup battery!
I'm going to use the traffix light with an ultrasonic sensor in the garage so my wife will know when to stop the car.

Today I got to playing with the NeoPixels. These things are cool! ... and Bright!
I finally got around to soldering the VU meter together. A hat tip @park_ind_ent for the tip on the dot mode. Works like a charm! :)
