This log contains the details of the mechanical stuff -- the dimensions and materials. I will attempt to generate a concise description of how to build the seismometer in the Instructions section. I believe these drawings are accurate. Sorry for the...
Tail-end of last year we were working on a nixie tube clock project. It ended up getting stalled by some other stuff, but while Novak was working on the microcontroller code I was grinding out a power supply and drive circuits. For drive circuitry we...
Begin with 200ml filtered water from the fridge tap, carried in an empty coffee pot. Using 4-6 ratio to calculate. 10x20 = 200ml H2O 4 grams sodium hydroxide x20 = 80 grams NaOH 6 grams silica x20 = 120 grams Unfortunately we only have 92.8 grams of...
Not sure what shape I am going with I wanted to ration bars for mini mill and a 3d printer or 2 3d printers.Please advise if there is a solid way as this is the typical box type. I didnt like the prusa and I wanted enclosed.Over 60% of items have arrived...
Calibration1. #define CALIBRATION in software and recompile and flash ATtiny8612. For each range make two measurements in order to calculate the line v=k*ADC + m. With this simple approach I get about 10-20mV and 10-20mA accuracy ( compared...
There are many monochrome OLED display modules available for really reasonable prices out there. They can be really useful for a small and simple display in a project. However, many libraries available for driving them are rather big and slow. In this...
Connect USB cable to Fubarino and to your computer. Fubarino console will appear as a virtual COM port on your computer. Use any terminal emulation program (like putty on Windows or minicom on Linux) to connect to this virtual COM port at baud rate 115200....
Disconnect USB cable. Plug LCD4884 shield into Duinomite board. Now connect USB cable and plug it into your computer. Duinomite console mode will appear as a virtual COM port on your computer. Use any terminal emulation program (like putty on Windows...
As the prototype worked better than expected, clearly I needed to make something more robust and useful. Ideally mechanically solid, in a case, powered by a 12V wall wart, coax connection to scope and generally a lot nicer. 450A/V is going to be useful...
Liam from PCBWay ( www.pcbway.com ) kindly offered to sponsor making some proper PCBs so I've designed a proper PCB with Kicad 6. So far, I'm impressed with the process. There's a plugin for Kicad that uploads the gerbers in one click. The position and...
The new r5B12 PCBs arrived from ITEAD few days ago and I managed to assemble them to test if new added features are working as expected. All boards are now a little bit larger and I tried to keep the same mounting holes spacing as in previous builds.AUX...
I wrote a simple Android application to decode the SSID and display it, unfortunately I am having a slight issue. Some control characters are handled incorrectly by the ScanResult class.Original string:\x53\x50\x53\x3a\x41\x55\x53\x00\x00\x63\x3b\x15\x0b\x07\x3b\x76\xff\x31\x07\x5b\xcd\x15\x9c\x80\x07\x00\x00\x20\x04\x00\x00Android...
After finding a repository with software utilities for this chip, I tried to use the MPTool, which after first inspections seems to provide flash read, erase and write functionalities. When clicking the Detect button it lists all available COM ports...
Theory Channel capacity Shannon-Hartley law: where C is channel capacity [bps], B is bandwidth [Hz] and S/N is signal/noise ratio. Example: dPMR (C = 4800bps, B=6250Hz). So S/N must be at least 0.70. Number of bits/symbol needed Nyquist's Theorem...
