Arduino Mega based Speedometer and Tachometer

at 5:09 pm. Filed under Electronic Hacks

 

Gravi Capa is building a great looking Arduino Mega based speedometer and tachometer. It is still a work in progress and hopefully Gravi shares all the build details when he is complete. You can see the display performing a self test above and a rev test below when he tied it into his Honda motorcycle. The LED based display should look great in all lighting conditions!

Dead Macbook Pro Logic Board Diagnosis

at 7:06 pm. Filed under DIY Hacks

 

Louis Rossmann shows us how he troubleshoots a Dead Macbook Pro Logic Board. He goes deep into the diagnosis using his microscope and a nice big monitor to nicely view the schematic. You can tell that he has been through this circuit many times since it seems to be a familiar as the back of his hand. 

“Here I diagnose a board that has issues on PP3V42_G3H which caused issues with the MCP, whose clock circuit is powered by PP3V42_G3H! I go through my diagnostic process and mindset, and follow from beginning to end as I resolve the problem.”

DIY Mini Gimbal Project

at 11:40 pm. Filed under DIY Hacks

 

There are quite a few camera gimbal projects around. They allow for smooth fluid video capture even when hand held or mounted to things like quad copters. You can purchase kits and fully assembled systems but by looking at a few and getting an idea of the basics you should have enough knowledge to build your own.

DIY Animatronic Puppet Head

at 4:47 pm. Filed under DIY Hacks, Electronic Hacks

 

The Ben Heck Show has a cool DIY Animatronic Puppet Head project. This project listens for speech and moves the puppet mouth accordingly.

 “In this episode Ben sets out to help Backflip films with their upcoming puppet movie The Princess Knight. The film requires its actors to memorize prerecorded dialogue in order to match it with the mouth of a puppet. In this episode Ben sets out to create an animatronic head that would move its mouth automatically by detecting the highs and lows of audio waveform.”
