DMA on the STM32H7 DMA on the STM32H7 is a beast, with each incremental improvement as their hardware got better represented by a different interface. There's the BDMA, the regular DMA, & finally the MDMA. The mane one used for accessing...
How does it work?The Laser Glow Writer works by being controlled from and Arduino Due that is running the TinyG CNC motion controller firmware. The Arduino then controls the 2 stepper motors (X and Y axes) in a coordinated fashion while turning a small...
Overview: This is what this UPS must do: Communicate to the Pi the battery chemistry used and the charging status (Charging or Fault). This is a must for this application, where multiple chemistries are allowed.Provide power to the output ( the Pi power...
After receiving the card I took a look at the website and saw a firmware update utility (FAFWUpdateTool_v10004) and from my previous research this was possibly the key to figuring out more to this device. So I installed it and read through the documentation...
The General IdeaI want a vacuum pump. Mainly so that I can aluminize my own mirrors. Yes I know you can send them off to a company and get it done for pretty cheap. But I want to do it myself, in my garage, and this being Hackaday I trust that you are...
Join us on the Hacker Channel to discuss the 2016 Hackaday Prize and Hackaday World Create Day, our first live global event on April 23rd! If you're not a member already, request to join from the Channel page. This meetup will be co-hosted by Hackaday...
Wyolum co-founder and Hackaday writer Anool Mahidharia found mitxela's project and wrote about it here. Tim Alex hand wired his on protoboard, and Anool, being a Kicad wiz whipped out a PCB version.It's all cleverly based on VUSB, and uses their sample...
Most of you probably know me already , I'm @sulfuroid , the mad doc who never sleeps with over 150 github projects so far., the creator of various BLaK-RPI cyberdecks. (Sharpikeebo, BlakRPI 2K, BlakRPI Clive). This is my last and curret...
As my pint of commercial etchant reached the end of its useful life I began to wonder if I could make my own. The commercial stuff works well enough, but it costs an arm and a leg. I paid $20 for 500 ml (that's about pint for you non metric folks). Plus...
There seems to be a need for stand-alone step-up and step-down DC/DC converters in Radio Controlled aircraft. I'm thinking about possibly making a long range quad copter that runs on a single Li-Ion 18650 battery. Unfortunately, most FPV cameras and...
How does it work Starting with a central location, a destination at specific distance is randomly calculated with a trigonometry formula. Having an origin and destination, walking directions are requested to Google Maps API. At this point feet starts...
Step 1: Gather the Supplies Getting electronics supplies online can be a bit worrisome because you do not know if the components / modules you purchased are in working condition or not. So to erase these doubts I recommend UTSource.net for...
Micro controller and logging The readily available and cost effective Arduino UNO was used as the logging device micro controller. However using only the Arduino and exernal sensors poses two problems. Firstly the internal EEPROM is only 1024 bytes....
Please Don't Like or Follow This Project -- There is a newer/better version: The Ultimate Single Cell Lithium UPS for Raspberry PI (U1LiUPSRPi). Check it out.I started out trying to modify the super capacitor UPS system, but it quickly became apparent...
This project is sponsored and supported by JLCPCB - Manufacturer of Printed Circuit Board and offers 5 free PCBs of Arduino Compatible Board. For this project, we'll use the JLCPCB Arduino Compatible printed circuit board presented below. Figure...
