The Reason Behind All Metal Hotend Jamming

The Reason Behind All Metal Hotend Jamming

Recently we got a complaint from one of our customer that the PLA is jamming in Chilly All Metal Hotend, which we make. To address this issue we did some quick search and found that JAM is common to any hoted in the world (say e3D, Prusa, etc.) , here are some helpful topics why the JAM occurs especial with PLA filament, but not on other high temperature filaments.

ARM Adds Cortex-A32 Support To GCC Compiler

ARM Adds Cortex-A32 Support To GCC Compiler

ARM only announced the Cortex-A32 ARMv8 32-bit processor yesterday but already they’ve gone ahead and landed the support inside the GNU Compiler Collection.

It’s not an entirely big surprise that there is already compiler support baked for the Cortex-A32 considering this is just an ultra power efficient cut-down version of the ARMv8 that runs in 32-bit mode. The ARMv8 64-bit support has been maturing in both GCC and LLVM/Clang for quite some time already. However, it’s nice to see the quick turnaround time by ARM on getting the support upstream.

This commit that landed in GCC trunk this morning by ARM’s Kyrylo Tkachov adds -mcpu=cortex-a32 to GCC. This addition will be found in GCC 6.


ARM Cortex A32 from ARM

#ARM #CortexA32 from ARM

Cortex A32, a new super-small ARM core designed specifically for wearables, Internet of Things things, embedded systems, low-cost boards like the Raspberry Pi or Pi Zero, and other places where power, space, and cost savings are more important than raw performance. It uses the ARMv8 instruction set and is intended as a replacement for the older Cortex A7 and A5 architectures, both of which use the ARMv7 instruction set. However, the Cortex A32 can only run 32-bit code—to save space and power, the ability to run 64-bit code has been removed.

Atlas – Next Gen Humanoid Robot

#Atlas – Next Gen #Humanoid #Robot from Boston Dynamics

That robot you see being pushed around is the latest generation of Atlas, the insanely advanced humanoid robot as built by the Google-owned Boston Dynamics.

VGA Adapter for the Pi Zero

#VGA Adapter for the #RaspberryPi Zero user [mincepi] designed a PCB that mates with a VGA monitor and the Pi Zero board and–according to his estimates–costs about $3.62 each

You can order the boards from OSHPark, or you can make boards yourself. There are even instructions for recycling old VGA cables for connectors if you don’t want to buy new ones. Read more

555 IC teardown – microscopic view of 555 IC

555 IC teardown – microscopic view of 555 IC

Above photo shows the silicon die of the 555 through a microscope. On top of the silicon, a thin layer of metal connects different parts of the chip. This metal is clearly visible in the photo as yellowish-white traces and regions. Under the metal, a thin, glassy silicon dioxide layer provides insulation between the metal and the silicon, except where contact holes in the silicon dioxide allow the metal to connect to the silicon. At the edge of the chip, thin wires connect the metal pads to the chip’s external pins.

How to make a speaker using a simple balloon

Lean #Howto make a speaker using a simple balloon

Having made a speaker out of a balloon, you may play tricks with children by painting face on the balloon. There are a lot ways to use such an interesting speaker, depending on your fancy!
What do you need?

  • Wire
  • Scotch tape
  • Balloon

The bigger the balloon – the louder would be the sound!
Wrap the wires around your hand and fix them with the tape, measure the diameter of a magnet beforehand. Strip the wires and fix them with the scotch tape on a balloon. It is preferable that the wires lie down better to a balloon.
Link the wires to an audio system, MP3, TV, PC…
In the middle of wires set a magnet and listen to the music!!!
Well, we have got such a hand made speaker out of a balloon!!!
Try and experiment! You will succeed!
