Make the world’s cheapest MIDI tester
Jesse from Bent-Tronics has posted a tutorial on how to make a DIY MIDI tester: A quick and dirty (and cheap) MIDI tester. Sometimes you just need to know if a MIDI controller is outputting anything. Even many high-end MIDI modules/boxes will have a “MIDI Activity” light, just to let you know something is being transmitted/received. That’s […]

Neoway M590 GPRS tutorial on sending and receiving files from/to SD card from Vadim Panov: Here’s a bit of useful info from what I’ve been doing lately. I got a job to design a device that connects to a web-server via GPRS and downloads a bunch of tiny WAV files, that it later plays on […]
Chrome Apps and serial port communication
Luca Dentella writes, “When it comes to develop a GUI for your project, you may need to be sure it will be available for users under Windows, Linux and MacOS. Chrome Apps may be the solution: they are developed using the same technologies behind any websites (HTML5, CSS, javascript) but, thanks to the Chrome APIs, […]
Getting started with OPENOCD using FT2232H adapter for SWD debugging
Yahya Tawil wrote a tutorial about flashing EFM32 MCUs with OpenOCD using FT2232H adapter: Learn how to make flashing your ARM-based MCU easy by using OpenOCD debugger with an FT2232H adapter. Old MCUs from vendors like ATMEL and MICROCHIP, like the PIC16F and Atmega family, tend to have a special programming interface to program internal […]

Using Altium for a DirtyPCBs order
Jarrett has written an article describing a technique of using Altium for a DirtyPCBs order: This is a pretty rare combo: using a premium PCB package with the budget board house. Kinda funny. Generally these small run PCB houses provide DRU and CAM files for EAGLE design rule checking and Gerber outputs, respectively. Because I’m […]
How do I FPGA?
TC-Engineering writes: I’ve been thinking about building stuff with FPGA’s for a while, and usually get turned away because FPGA’s are considerably harder to implement than microcontrollers since they have no on-chip memory. It is necessary to re-program the gates every time they power up, which requires an external flash memory chip. There aren’t great […]
Making PCB vias with conductive ink
Here’s an alternative method for making PCB vias using conductive ink from Diyouware: We developed an alternative method for making PCB vias through-hole using our robot. As you probably know the traditional DIY method consists in threading a wire through the holes and then soldering it and then cutting it off. For example, if we have 100 vias in […]
