So, one morning, I wake up, scroll through some Reddit posts (one of the bad habits I have), and stumble upon a guy posting about his flip dot display. Well, it didn’t take me long to figure out I ‘needed’ one. Before that day, I had never heard of those...
First, the video: Second, you can purchase copies of many of the things mentioned at https://mjbots.comThis is basically a summary of everything that I've posted on hackaday, https://jpieper.com, instagram, and youtube for the last year. Highlights:...
Update: PCBWay has kindly offered to sponsor the cost of the next run of boards! This is amazing, as I was planning on doing a comparison between JLC and PCBWay in my next post. Follow this space for more soon!The boards: The Boards Were received...
03/09/2023, 13:20, Sunday. Well, I'm writing this² after finishing this project log because I feel like I failed this project log. Even though I reached a few conclusions on how much energy I would require depending on the type of...
Okay so i found someones code on how to send tts to google homes. after some major modifications and copy paste from my old code i have it working. Here is the github location i borrowed it from https://github.com/debsahu/GoogleSay his was cool...
Hey there,long time no see. Albert from avdweb is working on a SAM D21 board, and he wrote me an email asking me for some help; he acknoweldged that the Arduino Zero has way less broken out pins on the three headers than the SAM D21 G actually has, but...
Here is a summary of the design so far. FC1 or F-CPU core #1 is the successor of FC0 which was designed more than 20 years ago. You can have a look at the original F-CPU manual for an overview of the original concept and history. FC1 is a more mature...
(UPDATE: Multiple DIMMs now functional... inverted clock-signal. See bottom)The last log had a bit of a "scare" regarding the clock-signal, shielding, etc.It's really not that big a deal. I replaced that long-shitty wire with a shorter and (by feel)...
I was not afraid of writing driver code for the ADC module, and I did. When I later built the NodeMCU firmware, I found that this driver was already written and available for inclusion. Nevertheless using such a driver would be difficult without reviwing...
After a wild December full of socialising, dancing, heavy drinking and other joys of student life, it's time to switch back to the "geek mode" again. Having my "Arduino to IDE" interface built and (more or less) understanding how it works from the hardware...
After testing the sensor just a brief summary. The sensor used is a cheap one purchased in china. Has no brand and is labeled as v 1.2. After a brief inspection the sensor seems to be similar to DFRobot's. A capacitive sensor based on a 555 oscilator...
While waiting for our big LED matrix, we decided that we would try it with only one to begin with. This was, without a doubt, our hardest step, we spent more than 10 hours on this, we tried many codes, and we downloaded many libraries, but nothing seemed...
Trial and ErrorOptimising the code is tricky as there are so many parameters. One approach is to extract the data from the Arduino and model the code in Excel. Once the Excel model faithfully mirrors the Arduino the the parameters can be tested. Here...
Edit: Fixed the thingiverse page with the STLs!This is the written project page for my video on the same topic: This is the K40 laser cutter. The epitome of cheap Chinese manufacturing. Cheap enough to risk it, and just expensive enough to warrant...
Updated 6/26/17 1:58:PMI updated the code significantly, I added " lcd.setCursor(12, 2); lcd.print(i--);" to the lines of code that control the motor coils so the current shaft position can be seen on the LCD display, and incorporated a pin int sensorVal[]...
