Summary of Exploring the Transcend Wifi-SD card
This article critiques poor hardware software quality and introduces the Transcend Wi-Fi SD card as a compact Linux computer. The author highlights its ARM processor, 16GB memory, and built-in Wi-Fi chip, noting its compatibility with OpenWrt and similar to Trek's Flu-Card and Pentax's O-FC1.
Parts used in the Transcend Wi-Fi SD Card Project:
- 16GB Memory Card
- ARM Processor
- Wi-Fi Chip
- SD Card Package
It’s been my experience over many years that hardware people are responsible for rubbish software. Years upon years of shoddy hardware drivers, dreadful software bundled with cameras (Canon, Pentax I’m looking at both of you); Printers (HP, Epson), Scanners (HP – one day I might forgive you) have provided the evidence. Since leaving Microsoft I’ve spent more time working with Linux, and every so often I get into a rant about the lack of quality control: not going back and fixing bugs, not writing proper documentation (the “Who needs documentation when you’ve got Google” attitude meant when working on one client problem all we could find told us it could not be solved. Only a lucky accident found the solution). Anyone can program: my frustrations arise when they do it without proper specification, testing regime, documentation and “after care”. The Question is … what happens when Engineers botch together an embedded Linux system.
Let me introduce you to what I believe to be the smallest commercially available Linux computer and Web server.
I’ve bought this in its Transcend form – which is available for about £25. It’s a 16GB memory card, an ARM processor and a WIFI chip all in an SD card package. Of course chip designers will be able to make it smaller but since it’s already too easy to lose a Micro-SD card, I’m not sure the would be any point in squeezing it into a smaller form factor. Transcend aren’t the only firm to use the same hardware. There is a page on OpenWrt.Org which shows that Trek’s Flu-Card, and PQI’s Aircard use the same hardware and core software. The Flu card is of particular interest to me, as Pentax have just released the O-FC1 : a custom version of the flu card with additional functions including the ability to remotely control their new K3 DSLR. Since I don’t have the K3 (yet) and Pentax card is fairly expensive I went for the cheap generic option.
For More Details: Exploring the Transcend Wifi-SD card
- What is the Transcend Wi-Fi SD card?
It is a commercially available Linux computer and Web server featuring an ARM processor, 16GB memory, and a Wi-Fi chip in an SD card package. - How much does the Transcend version cost?
The Transcend form is available for about £25. - Does other hardware use the same components?
Yes, Trek's Flu-Card and PQI's Aircard use the same hardware and core software. - Can the card be used with Pentax cameras?
Pentax released a custom version called the O-FC1 for their K3 DSLR that includes remote control functions. - Why did the author choose the generic option over the Pentax card?
The author chose the cheap generic option because they do not own a K3 camera yet and the Pentax card is fairly expensive. - Is it possible to make the device smaller?
Chip designers could make it smaller, but the author argues there would be no point since Micro-SD cards are already too easy to lose. - Where can one find information about compatible open-source software?
A page on OpenWrt.Org shows devices using the same hardware and core software.
