A lot of cool modules and sensors…

I am buying electronic stuff from AliExpress – due to the ******* custom policy of EU it is a much cheaper than buying from Adafruit, Sparkfun etc. Unfortunatelly. There is a lot of total crap, but also a lot of great stuff too. I am diving into AliExpress three times a week, and I found many pieces “I really have to build”. So I decided to share these tips with you and made a new web called Alitronik.

There are three tips per day at Alitronik, and each sunday is “a Funday” – a day for tips with something in common. For example – the last one is dedicated to solar power, energy metering, weather stations and lasers. Previous week was in the sign of Raspberry Pi cases, tools, robots and construction of 8085-based mini PC.

From the recent post I want to mention e.g. 37 sensors kit, CC-A80 Cubieboard PC, Speech Recognition Module, LoRa Shield for Arduino, NodeMCU-32S or SMD Tweezer and multimeter tool.

So – bookmark Alitronik.com, read Alitronik RSS, follow @alitronik_tips, subscribe weekly digest or submit your own tips.

Face it: I love old computer, but I really hate FDD. It’s too breakable technology, so fragile and a little bit expensive nowadays. If you wanna the most possible fidelity and retro feeling, you have to use FDD, but if you love to experiment, like me, you appreciate this tip: Buy Gotek FDD emulator. You can connect it to the standard FDD controller as usual, but fron the front side you have an USB slot to connect USB memory stick, which acts like a lot of diskettes. And, here is a tip 2: Using Gotek as an Amiga FDD. Author hacks its firmware to make it work with Amigas.

Hurry to the Kickstarter, pledge this:

This kit is small, smaller than a credit card at only 1.8 in x 3.0 in. That means you can put it inside some pretty small projects.  It is bread board friendly, so you can quickly connect it to a shield or to a bread board.

It features:

  • The Spartan6 LX9 FPGA from Xilinx, one of the best FPGAs on the market.

  • An on-board USB JTAG Programmer to power and program your FPGA with any open source programmer, like the one inside our own Scarab IDE.

  • An on board USB interface that powers the board and allows communication with the PC at speeds up to 480Mbps. (That’s fast enough to make a logic analyzer. Check our website for updates on projects and tutorials).

  • An on-board HDMI port. Instead of using VGA output on your projects, now you can go HDMI.

  • An 8-channel analog to digital converter running at 1 MSPS with 8 bit resolution. So you can start connecting real world sensors to your FPGA kit.

  • Memory: 32MB of SDRAM, 64Mbit of SPI Flash and a microSD card interface.

  • stereo audio output jack using 1-bit sigma-delta DAC to start playing your music.

  • 24 Digital I/O pins.

  • 8 LEDs.

Wanna learn FPGA and that things around? Try Nandland. It gives you a brief insight, deeper explanation and point your attention to the common mistakes.

Nandland intends to be a one-stop-shop for all things digital design. All of the articles on this webpage have been written for people who have little to no background in Engineering. Nandland is constantly being updated with more content. If you are are beginner to the world of Digital Design, check out the lessons at FPGA-101. That will give you a solid foundation in your journey to learning FPGAs and ASIcs.
