Title: Help purchasing machines for a Summer Camp
Post by: rossmau on Apr 24, 2018, 04:24 pm
I need some guidance here. I run a summer camp class that does a whole lot of tinkering with different aspects of engineering. Three of the topics that I need computers for are 3D modeling, programming and circuits. I do a couple days of getting kids introduced to tinkering with the Sparkfun kits and building some basic circuits and programs.

The problem is that I'm a public school teacher, and this is for a summer camp, not affiliated with the district. My principal used to let this summer camp organization rent my laptop cart on the cheap, but higher ups have put a stop to that. I found a donor that is willing to spend about $2k on laptops that I can use for the summer camp.

What would you recommend? I used to use Autodesk inventor when I had my windows machines, but I'm thinking since it's a pretty basic intro (the kids are 12-16 years old) that I could get Chromebooks and use something like On Shape.

The problem is I have read conflicting stuff on using Chromebooks for Arduino development. Is it a reasonable option now? I'm trying to go as cheap as possible, so the kids can work in singles and pairs, not groups of 3 and 4. Anyone have experience with this? Perhaps even running this in a classroom setting? Are chromebooks appropriate? Is there a similar price point for a windows or Linux machine?

Here is some information on using Chromebooks with Arduino, that my GrandsonTheEngineer wrote:

Not sure about prices on machines... 

He also wrote this, showing the construction and programming of a low-cost robot kit with Chromebook:

Let us know how this works out; this is a BIG issue in schools, especially in the coming school year...

The Arduino Web Editor Chrome app subscription is significantly cheaper if you have an educational account:

That sounds quite reasonable to me but depending on your financial resources it may still be a consideration vs. the free Arduino IDE software.

Other than that, the major downside I see to Arduino Web Editor is that it's not so much under your control as the Arduino IDE software. If there is a problem with the server or the internet then your class is ruined. Updates will be rolled out with no notice and no matter how careful the developers are bugs do happen. With the Arduino IDE you might have some problems getting it installed but you can do that in advance and once it's on the computers and working you have a reasonable expectation it will work during the class just the same as when you were doing your prep.

A common issue we see reported here is caused by the >1400 3rd party libraries that are pre-installed on the Arduino Web Editor. Sometimes there are conflicts between the libraries. That would be much less likely with the Arduino IDE since you would only install the libraries you wanted and if there was a conflict you always have the option of removing the library causing the conflict. With the Arduino Web Editor there is no way for you to remove the pre-installed libraries. All those libraries are quite easy to install in the Arduino IDE's Library Manager (Sketch > Install Library > Manage Libraries) so I really don't see a huge benefit to having them preinstalled.

Another common complaint about the Arduino Web Editor is that it doesn't allow you to install support for 3rd party hardware. You only can use it with the official Arduino boards or unofficial boards that are compatible with the hardware definitions of the official boards. For an introductory class that would likely not be an issue since likely your students be using 3rd party hardware that requires the installation of a custom hardware package (ESP8266 for example).

There are some sort of neat "cloud" features of Arduino Web Editor which make it easy to share/collaborate/embed sketches. I haven't found any of that to be super compelling yet but I don't use it very often.

I know it is possible to use Linux on Chromebooks (Crouton) so that could be another option if the Chromebooks were the best value but you still wanted to use the standard IDE. I have no clue how feasible that would be for your usage.

I found the pair as the most appropriate for engineering learning. Kids also learn how to help each other and to share knowledge.

I am speaking about 9-13 years old students.
