Alas winter has hit the old homestead hard, with most of the family down with or recovering from variations of head, chest and other colds.Hence not much fun stuff happening..... However I did start thinking about how to get diagnostic info to ...
We've made this funny project for a German crane manufacturer. It's a PONG game based on the Raspberry Pi 2, written in Python and controlled via 2 heavy remotes for cranes. www.youtube.com/watch
IntroductionThere is plenty of jitter on signals generated using GPIO on the Raspberry Pi and many other computers, and this is due to the fact that Linux can context-switch user processes at any desired point in time dependant on its scheduler (for ...
Having now resolved (hopefully) the hardware issues with the GPS and display mounted simultaneously it was time to check out the GPS reception and ensure that I was seeing good NMEA data on the serial interface.My problem is that the area where I do ...
Halloween has always been one of my favorite holidays, so much so that I founded a business that makes professional-grade props and controllers for Haunted Houses. This naturally led to Element14 asking me to create a couple of projects that were eas...
#ShareTheScare this HalloweenVisit our Halloween space and find out how to win one of two Cel Robox 3D Printers. There are two ways to win:Build and document your past or present Halloween projects.Tweet your best engineering spook with #ShareT...
I was quite happy to get the Pi LCD display working by following the blog posts, but was disappointed to find that when I had both the MicroStack GPS module and the Display Board connected, the GPS Board stopped working. By a few elementary tests thi...
I'm working on a 3D controller hat for a Raspberry Pi. This is a glimpse of the hardware prototype. You can see the USB and ethernet ports of the Pi on the left side. Features: 4 motor control channels - compatible with A498...
By LDR (9 years old) (+dad)IntroductionIn this game, you roll coins down a ramp onto a board with foil islands. When the coins make a bridge from one side to the other, it is a complete circuit and an LED lights up. Simple series circuit with ...
Today was spent soldering the Pi Shim and finding out exactly how bad my soldering skills were. Overall though not too bad and once completed it was time to mount the GPS on the microstack and the subassembly onto the Pi. Once powered up I follo...
In Part II: OS Configuration and Software Installation & Update, I showed how I configured the OS and installed software. In this part III, I will show the problem of SHIM and how I made it work. To test the kit, I first tried cgps program a...
Finally got to unboxing the hardware and seeing what was supplied for the geocaching build. The Pi2 looks good, particularly with the additional USBs and the reduced footprint with the micro-SD card. I mounted the Raspberry on a board that I can...
For those of you who want to get into lower level programming and high speed applications, c++ is a magnitude faster than Python. Especially when it comes to parsing NMEA strings. At 1hz 9600 baud the performance gain isn't noticeable, bu...
If you want to use your GPS for more real time applications or for doing some software accuracy improvement you will most likely need a higher output speed.To get a higher output speed from the L80 GPS module you need to increase the rate/frequency. ...
Raspberry Pi Geocaching System (Pi Hiker)Author: Bob AlexanderA kid friendly, high accuracy geocaching platform.Accuracy of the GPS location could be improved by putting the L80 into 10Hz mode and then performing an averaging and filtering function s...
Getting excited to let this TB loose in the big wideOpen world. Here it is all dressed up. Have set the Goal to travel to Wanaka to experience the beautyOf New Zealand. Maybe I can meet it there one Day.......
I was thinking this little kit might make an excellent ground station for my model aircraft.I have a little 900MHz telemetry system that could be connected over serial to the Pi and I should be able to use the Pi to send commands to the UAV... W...
Just a simple Python script to display the location data to the LCD (PiFace CAD):*This is not by any means a clean program - I haven't removed unneeded imports and the display portion includes a counter I was intending to use but haven't implemented ...
After a bit of trouble, I was able to get the basic GPS functions working!┌───────────────────────────────────────────┐┌─────────────────────────────────┐│ Time: 2015-08-06T02:07:10.000Z &nbs...
I won a Raspberry Pi 2 GPS kit!My intent is to create a kid friendly, high accuracy geocaching platform that my daughters can use when hiking.Technical specs:Accuracy of the GPS location could be improved by putting the L80 into 10Hz mode and then pe...
The element14 trackables are running free around the world, and scurrying into the far corners of the global geocaching arena thanks to a legion of members who've set them loose. To celebrate our treasure-hunting helpers we've put together a ...
