News - T³: Etching your own cir…
about 3 months ago
In my intro to electronics class the first board I get the students to etch is using wax. They dip the copper board in wax, scratch away the areas they want to etch. This makes large traces but easy to fix mistakes, drill and see the process with almost 100% success. We make a very simple skill tester game. We then go onto design programs etc and use a aerated tank from the printed sheets.
Going to start playing with interesting designs from my work with illustrated-never thought of that.

I think that the IMU and battery shield would the best shields for me. I am a teacher in a small country high school in South Australia and we enter the UAV Outback high school Challenge each year (https://www.uavchallenge.org).
For this challenge the students need to design a system to drop an epipen from an RC plane to Outback Joe. The problem is they are inside a tent. To know where the plane is for the mission system will make it easier to drop the epipen.

Yes it was said a few years ago when Dick Smiths went to be the Techspets - going with tvs, computers, etc, btw they went broke doing this and was sold off by their parent company. I learnt electronics from their Fun Way into Electronics Kits (vol 1, 2, 3).
Tandy was the Australian version of Radio Shack and we had one in our town - it was good as they stocked some of the dick smith stuff too.
We now have Jaycar and Altronics - thse are for the electronics hobbyist and do an excellent job. They carry Ardunios, and many introduction kits (Jaycar’s short circuits kits are the same thing as the dick smith kits - great for kids learning)
that’s my two cents

As a teacher I would like to build a wearable sound machine that I can use to interact with my class. It could get a wireless signal from the computer when a student get a question right. It could randomly say a students name to answer a question or if I press a button it could play music or a memory jingle or something. It could also interact with the loudness metre tie that I am building with pixel gear from adafruit.
the kid love it when I do something weird like that. I keep getting in trouble because my classroom looks like a makers space.

We use Creo at school and the students find it easy to use - similar to solidworks but ‘free for educational use’

Why are these kits $1,250 when the inventors kit without retail box is only $95 ie 10 x $95 is only $950. Is there something extra that isn’t in the just the standalone kit?
Just wondering as I have a very tight budget and $300 is almost a semesters electronics budget.

It is very adhoc and dependant on the flavour of the month. Remember that the government and associated bodies need to justify there spending. Here in Australia during the GFC the governement spent there way out of recession (and it generally worked) by buying a laptop for every year 9 to 12 student - problrm was at school we didn’t have the inferstructure to handle these laptops to be added to the system - so they upgraded each of the schools with the minimum solution - they then had to come back and upgrade it to make it ackually work. now these laptops are getting old and we are trying to find out how to replace the laptops for the next wave of students (and we have a school of only 200 students)

the ICSP header is if you want to program it as a PIC. the Picaxe only needs two resistors and a basic serial connection to program.
There are many great and varied boards about that are build for various applications (not just the restrictive adruino footprint) and it is easier to breadboard.
In terms of language and uses each have their own benifits, as a teacher, picaxe basics is alot easier to teach and for the students to understand without all these hidden libraries but then again it doesn’t have some of the functions that arduino has.
I prefer PICAXE and that is my decision, what would you prefer and amstrad or commodore 64?

for the picaxe lovers out there - here is some picaxe code using the 18m2
love the bright vivid colours that can be produced, massive current draw though.
what is the policy of replacement if the water prof casing cracks? the first led isn’t showing due to a crack in the sealant.

Many of my students will be presenting at the Concept 2 Creation Expo in Adelaide South Australia on 10th and 11th November - many projects inspired by the news stream here - the fashion parade was watched with wonder by the group making wearable electronics. If you want more info I can add it.
