Your Raspberry Pi Projects

Or get yourself an odroid, if is a small router/server you want then pcengines does a nice low power box called apu2 which is x64 and has 3x 1gbe
 
I builded a handheld weather station. Its unique future is the solid state anemometer (wind velocity). It uses the extreme accurate Sensirion SDP810 125 pa micro thermal flow sensor made in Switzerland available from digikey and rs components.

It can also measure temperature, humidity and barometric pressure, altitude and dew point with the Bosch BME280.

thats cool!
what was the total cost?

Nice one Jaco! Now can (at least some of) that be achieved using Arduino or PIC to reduce costs I wonder...
 
In similar spirit to my post here, I got SETI@Home / BOINC running on my rasp.

Looks like it can run at 50% capacity around the clock & maintain a stable low 60s temp.

I want to build a PM2.5 thing but the reliable sensors are quite expensive. 400zar ish. Cheaper ones seem unreliable.
 
Hi all, new to this thread and the PI for that matter.
Where will be the cheapest place to buy a PI either locally or importing?
I want to try one out, I'm not yet exactly sure which model or what I want to use it for, but I'm getting in to the ham radio hobby and those guys are doing pretty interesting things with PI's.

Hi and welcome.

Locally I would suggest either https://www.pishop.co.za/ or https://www.hobbytronics.co.za/

The Pi Model 3B should be fine for what you want to do. I do believe the 3B Plus is still not registered with ICASA as of yet so no one stocks them locally.

Remember to get a decently fast MicroSD card to eliminate any storage bottlenecks, and use the official RPi power adapter as using subpar, lower amperage ones can cause OS corruption or other issues.
 
Had my first attempt, so far so good.

Next step is to control a relay instead of an LED with telegram in order to turn off the geyser...

Due to Mybb's new crap app I'm unable to upload a gif.

Et Tu Thor?

I haven't been able to post a pic on the app for a month now. My title of best forumite ever is now at risk
 
If one would theoretically need to get hold of a RPi3b+ before the ICASA certification is complete, what route would be the best way to theoretically do it? Ebay? I would assume that a theoretical customs official wouldn't know the difference between a 3b and a 3b+ should one cross their desk?

Theoretically I would do it via Amazon. The total cost, import fees deposit added, comes to R958.75. This is for a kit with the board as well as a power supply unit and two heatsinks.

Given that you can get the 3B for ~R600 excluding shipping, is it worth the extra R350? Check here to decide: https://www.makeuseof.com/tag/raspberry-pi-3-b-plus-overview/

They key is the possibility of a couple, non-theoretical thousand USD in FCC compliance testing savings. Thanks for the tip.

Tons of stuff not certified gets imported.

Kinda surprised though...the 3+ was widely available a year ago intl so can't be that hard to import
