Test system:1. Use a web browser to browse to the raspberry Pi's IP address from another computer (or phone or tablet).2. After a few seconds the status page should be displayed with the current temperature and flow rate values.3. If it fails, try adding...
Just keeping this very simple, since there are so few parts:Mount and solder the components, snip off the leadsConnect a 15-18VAC wallwart adapter to the pins AC-1 and AC-2Take +/- 15VDC from the pins +VE, -VE and GND
Project and Printing SetupBefore you get started, please make sure you have a few things:3D Printer (or 3dhubs)Minimum build plate 200mm x 200mmNinjaflex (any color)Regular PLA or ABS
Print the main chassis in as few parts as possible with a maximum infill, to ensure structual strength. I printed mine on an Anycubic Mega X and was was able to print it in only 2 sections and used epoxy glue to secure the parts toghter.
I now had a pretty good idea what the final x and y dimensions were going to be. I wanted to keep the camera as close to the size of the Pi as possible, which meant the large battery had to fit snugly underneath the bottom of the Pi. I printed out a...
Guide for making Core version 1I did a few layers, then placed the nubs in. It helps to poke the allen key through the bottom of the mold and through the weave, then chase it with the bolt. tighten the nubs securely into place, continue applying...
1. The first thing I did after coming up with the idea is to find a way to control 3 sets of 8 leds on each with a minimum amount of wires. I found an article that talked about shift registers and went ahead and ordered a few to try them out. following...

The OpenLD SoftwareThis Qt C++ software require a few dependencies: the FFTW3 and nCurses library. Therefore, if you want to compile the Qt Project, make sure to copy the include files and the libraries to the project directory. If you do not want to...
The circuit can be constructed on good quality strip board (.1" pitch) and requires only a few tracks to be cut and some larger holes drilled depending on the slide switch available. Track cutting is easy using a sharp 5mm twist drill in your fingers...
We will need to cut out a few points in our case – we’ll need to allow a space for the headers (so we can connect the Lisiparoi to the Raspberry Pi’s GPIOs), and a square hole for the Raspberry Pi Camera Module. We’ll also need to drill small holes for...
Tune a software defined radio (I used this one) using SDR# (if you're on Windows) or another software application to 315MHz and push the keychain button a few times. You should notice a signal.
