“Hardware components

MCU: STM32F756IGK6 (ARM Cortex-M7, 216Mhz, UFBGA176)
HDMI transmitter: ADV7511W (165Mhz, LQFP-64)
SDRAM: IS42S16400J-5BL (200Mhz, 64 Mbit, FBGA)

 

Mathias created the MEMWA2 using a custom-designed 6-layer PCB just big enough (65 X 45 X 20mm) to fit the electronics, which include a STMicroelectronics MCU (Arm Cortex-M7 running @ 216MHz), 256Mb of Alliance Memory DRAM (200Mhz, 64 Mbit, FBGA) and an Analog Devices HDMI transmitter for wirelessly outputting audio and video to any display.”

LED Snowflakes by Mike Harrison

at 10:26 pm. Filed under DIY Hacks, Electronic Hacks

 

Mike Harrison built this interesting LED mall display. For single install design it is quite involved, the system is very flexible allowing for it to be easily programmed and interfaced to. The use of RGB and a white LED is an interesting way to ensure you get a pure white light with no color mixing needed.

How to Build IOT Devices – Talk by Joe Menard

at 11:33 pm. Filed under DIY Hacks

 

Joe Menard had many needs for IOT devices in his life, he is an electrical engineer but needed fill in lots of programming knowledge to get his ideas to come to life. He started at a very low level even building a switch mode power supply, with 170 volts on board trace spacing was something that was very important. For the enclosures he didn’t simply buy something and stuff his circuit into it, he custom designed it and 3D printed it.

Arduino State Machine

If you are looking for new ways of getting your Arduino gear to become productive why not try programming it as a state machine.

Via: Electronics Labs

 

“Did you ever program an Arduino? Have you ever been worried about complex control flows written in pure C? Maybe you have already heard of statecharts and state machines?

YAKINDU Statechart Tools for Arduino is based on Eclipse, YAKINDU Statechart Tools, and the Eclipse C/C++ Development Tooling (CDT). It sets up an initial project containing an empty statechart that you just need to fill with your own ideas. The only part that you still need to program on your own is the connection between the statechart and the hardware, i.e. initializing the hardware and updating the state of the hardware depending on the state of the statechart and vice-versa.”

Waveform Generator Record Player

at 5:57 pm. Filed under Cool Gadgets, Electronic Hacks

Light-sensor-atop-record-player-needle

 

When you need a Waveform Generator but just have a Record Player the obvious solution is to create a Waveform Generator Record Player.  This creation uses a 3D printed head for the record player arm and has some simple optics mounted. Similar optics that would be used in a line following car feedback the pattern. Swapping the disk changes the pattern.

“The light sensor is a 3 mm Everlight ALS-PT204-6C/L177. It was chosen because it responds to standard visible light, rather than infrared. I want it to see what I see.

The light sensor connects to +5VDC and to the middle pin of trimpot R3 (100 kΩ). My trimpot was dialed to about 20 kΩ, but you’ll need to adjust it based on the light conditions and distance to the target. The goal is to create as large of a signal as possible, with a compromise between flattening the top of the wave and the bottom of the wave.”

DIY Flexible Circuit Board

DIY Flexible Circuit Board

 

DIY PCBs are quite simple to make these days but DIY Flexible Circuit Boards are still something that is not easy and also not common in most PCB production houses. With this technique you can now dabble with flexible boards in your next project.

Thanks to Wheedal for the tip

 

“A fairly new elastomeric rubber filament is now available that sticks quite well to copper. It is called Ninjaflex. In fact, it sticks quite well to almost anything including acrylic, blue painters tape, and glass.

A circuit board pattern can be drawn in a free program like 123D Design and then extruded to a thin thickness and saved as an STL file. It can then be printed on top of a thin copper clad board or plated conductive fabric: step 1 pic. It can then be etched in the standard way with a Ferric Chloride solution.”
