South West Makers

Hi Philip,

welcome to the forum. I am happy to help out with things especially if it involves a Raspberry Pi.

Cheers,

Paul

Hmm, rereading your initial post, you could do something like this: ⋅ take a RPi camera photo ⋅ raise RPi pin high (to notify Arduino that's the RPi has finished taking photo) ⋅ Arduino sees the RPi pin go high ⋅ Arduino moves servo X (if it needs to) ⋅&n...

Hi Dylan, I presume you have a RPi Camera? When doing a new project, I find it's good to break things down into sections and work on each section until it's working, then 'glue' them together so to speak. Can you list out the steps, and what you have does so far, ie: can the RPi take a photo via Pyt...

I popped into the Darkroom back in 2012/13 and had a quick chat with someone doing some arty photography. I didn't discuss the Maker movement though. Later in the week I will walk up and see how they are going.

Thanks for the tip off.

I added in a few extra functions recently: ⋅  I can now press the ‘PrtScn’ keyboard button to save a screenshot of the MAP display. No more taking manual screen shots of the VNC screen and cropping the image down to the GIS-Pi screen. ⋅  Pressing ‘p’ on the keyboard will take a p...

apart from lugging a 2.6Kg Lead Acid battery around

Two weeks ago, I discovered that GIS-Pi would no longer run native form the CLI. All I get is a blank screen when being run from the CLI. It will only work when it's run via xWindows. I have spent a lot of time trying to troubleshoot the issue. At the moment, I am putting it down to a driver issue, ...

Let’s get physical. At the moment, the weight budget GIS-Pi consists of: 2456g - SLA Battery 12V 7Ahr 685g - HDMIPi + RPi B + RPi Camera 106g - wireless keyboard/mouse unit 100g - breadboard + GPS & volt/current modules 31g - external GPS antenna ~50g - misc cables (not measured) 212g - 4 x 1865...

At today's meeting we discussed the idea of setting up a robotics challenge. Arriving home, I see the Sparkfun have a new robot chassis from Dagu: m for more see: m There are some cheap chassis available online! Of course, we then need to add in all the other electronics etc. Rob mentioned this Jayc...

It was a bit of a quiet week, but I managed to get some quality geek time over Sat/Sun to work on a few things. I had a play with pyDoc and run pylint over the gis-pi project code files. I installed 'autopep8' python script and had it fix all the whitespace warnings. Very cool piece of code. I had a...

Other projects are starting to call out to me for attention, but I must remain focused. Well, that's what I tried saying over and over to my self last weekend. I looked over the L O N G projects ToDo list, and just picked off a few of the easy ones. When using python to talk to the GPSD service, and...

not very often you see discrete components these days. Usually one just slaps another chip in to handle the problem. keep the posts coming.

Hi Dylan, this video blog by Eben, spends the first 4 minutes talking about the upcoming RPi Display: m Essentially, there was a delay while they got some other RPi models out the door, ie: RPi 2 and there has been a delay with different countries certification of the unit. He thinks it should be re...

I picked it up via a special order from dx.com!

Not much work over the last weekend, but I did get a few specky things done. ⋅  I added a Waypoint data screen. This allows me to Add, Edit and Select the three waypoints that are going to be displayed on the Map dials ⋅  Used WP's are highlights in a different colour ⋅ ...

Did you read today's Slashdot article about the NIM programming language: m I bit, because i don't remember hearing about NIM before. Reading the 'Whats special about NIM' page, near the bottom it had a speed comparison of Nim, C and Python all generating Prime Numbers. The python example didn't imp...

Yes, it was the talk of the town for a while. I chatted with my Son that evening and even he had heard about it. I was impressed it made such wide news.

Managed to get some further work done on recording a manual GPS fix via the DATA screen. The screen will pop up two fields where I can record a quantity (count) of something and then some notes against the fix. These two items, along with a subset of GPS available info: datetime, Latitude, Longitude...

I managed to get some time in on the project during the week. I have separated out out more code so that I can now run multiple screens and I have added in a set of buttons across the top so that I can flip between them. The MAP screen (images above) is back up and working again and I have started w...

Hi BeJay, thanks for the tips. I can see that coming in handy, as I haven't really used the 7" screen yet. I am doing my Dev. work via VNC I was pondering screens on my way to work this morning. The 7" screen is a 1280x 768, but really I only need a 640x480 scree. At the moment, all my Dev...
