DIY optical power meter with SFP module and Arduino idea

Fifer optics power meter is an important tool for debugging fiber optics networks. I have earlier tested a cheap commercial fiber optic power meter a at Fiber optics power meter posting. Hardware hackers ares famous for building their own test equipment. The basic operation of optical power meter is quite simple: take a suitable detector,

Arduino serial plotter

I just found out a new useful Arduino IDE feature: Serial Plotter. It allows you to natively graph serial data from your Arduino to your computer in real time (no need for extra software for that).The Arduino Serial Plotter function has been added to the Arduino IDE since version 1.6.7. Here is introduction video on

SYZYGY – Next generation FPGA connectivity

http://syzygyfpga.io/# Open standard for high-performance peripheral connectivity SYZYGY is FPGA-agnostic and is intended to work with products from all major FPGA manufactures including Xilinx, Intel, Lattice, and Microsemi. PMOD and SYZYGY can happily coexist in the FPGA space and even on the same carrier implementations! FMC and SYZYGY can happily coexist in the FPGA space

Solderless breadboards

Solderless breadboards are one of the most fundamental pieces when learning how to build circuits and prototyping simple circuits. A breadboard is a construction base for prototyping of electronics. Breadboard are the ideal way to check out small bits of circuitry that you’re not sure about. Originally it was literally a bread board, a polished

Visual Development with XOD

https://hackaday.com/2017/08/13/visual-development-with-xod/ This looks interesting:  If you program microcontrollers like the Arduino, you should check out XOD and see how you like visually creating software. The software is open source and currently, can target the Arduino or Raspberry Pi. Some alternative visual programming tools: – LabVIEW RT or Matlab Simulink – both very powerful, very stable, closed source

The Definitive Guide to Pricing Your New Electronic Hardware Product

Ohttps://blog.hackster.io/the-definitive-guide-to-pricing-your-new-electronic-hardware-product-7305c19d2102 Setting the price for your new hardware product is one of your most important decisions. You need to get your pricing right as early as possible.  Pricing is a complex decision with many variables. If you mess this up it will be difficult to fix later.

Things you should evaluate before proceeding into test automation

https://www.valagroup.com/fi/2017/07/five-things-you-should-evaluate-before-proceeding-test-automation/ Test automation is not a magic button that can solve all your problems when pushed. Test automation is only a tool. Test automation requires longer initial development time and it is not cheap. Test automation only shows benefits in mid long term. Good candidates for automation can be test cases which: – take a lot

Wireless & IoT protocols & their security tradeoffs | EDN

This article is about securing them. The issue is that bad press and major security and privacy issues might slow down the adoption of IoT for improving our lives. Many end users are already skeptical to connect simple devices we rely
