Do Try This At Home
I believe one of Elektor’s first articles linking DIY electronics to ‘kiddie’ elec-
tronics was the Gameboy Digital Oscilloscope (GBDSO) from almost 20 years
ago. It was a blast. Basically, you plugged a module into a Nintendo Gameboy
game console and hey presto there’s a simple portable oscilloscope. Initially we
staged a Dutch-ish auction on the web to ‘test the market’, that is, check what
price our customers were willing to pay for the product. Eventually the Elektor
GBDSO reached sales volumes in the thousands across a period of more than
ten years. If that GBDSO were an Olympic athlete, it would be in the company
of Crescendo, EEDTs, Junior Computer, Filmnet Decoder, FT232-BoB, Pizza SMD
Oven and Pico-C.
Since it will resonate widely within the e-community served by Elektor, a
‘home modded’ product [xyz] with enormous popularity is sure to attract
weird questions from upright readers (mostly German), like “Where do I get
hold of a known-good [xyz], with full warranty, in mint condition, at the low-
est price?” to which we feel inclined to reply “Promise your kid(s) the new
Upgrade Plus model”, or “Dumpster-dive at the local thrift shop”. Likewise,
Q:
“Did you contact the manufacturer on this?”.
A:
“Techies don’t normally do
that, they read Elektor.”
I would unhesitatingly recommend to all you electronicists out there to hack,
fry, disembowel, blend, explore, rebuild or repurpose the tons of ‘closed’ elec-
tronics out there. It’s cheap, often free and in plentiful supply. Do rescue stuff
from skips and dumpsters filled by a generation that discards complete, plastic
bicycle lights because of two exhausted button cells. The electronics inside,
however trivial, is educational in providing clues to the design and construction
process. If you like it, repair it. If you don’t, formulate your criticisms and then
Widlarize it — but safely and responsibly. Reverse engineering is good engi-
neering. Do it creatively and with respect.

Wireless standards such as Sigfox and LoRa are available whenever battery-
powered sensors need to transmit data to an Internet gateway. Sigfox
scores high with a uniform and well-developed network. All the user must
do is program and log on the sensor nodes in order to visualize their output
data on the Internet. As we show in this series, cost-
effective hardware and free software are enough to
realize the first Sigfox projects. In the first
part we present the compact Arduino
MKR FOX 1200 module with an
integrated Sigfox transceiver
and a corresponding
motherboard.

Communication using UDP Packets
No sweat for the ESP8266
To exchange data over a network, a client/server model is usually used.
The client sends a request to the server, and the server sends
its reply in the form of an HTML page with
the requested data. This model requires
a lot of software: a server program
on a Raspberry Pi for example, and a
program on the client side that distils
the data from the HTML page.
