Hackaday.io User Reviews Six STM32 IDEs
One of the issues with getting started with any Arm-based project is picking a toolset. Some of us here just use the command line with our favorite editor, but we know that doesn’t suit many people–they want a modern IDE. But which one to choose? User [Wassim] faced this problem, evaluated six different options for STM32 and was kind enough to document his findings over on Hackaday.io. Many of the tools are Windows-only and at least two of them are not totally free, but it is still a good list with some great observations. Of course, the choice of an …read more http://pje.fyi/Nqjpy5
RaspiDrums Uses Expensive Sensorsa
RaspiDrums Uses Expensive Sensors
Piezoelectric sensors are great for monitoring mechanical impacts with a microcontroller. Whether you’re monitoring knocks on a door or watching a heartbeat, they are a cheap way to get the job done. They do have their downsides, though, so when [Jeremy] wanted to build an electronic drum set, he decided to use more expensive accelerometers to measure the percussive impacts instead. Even though piezo sensors are cheap, they require a lot of work to get them working properly. The ADXL377 3-axis accelerometer that [Jeremy] found requires much less work, plus provides more reliable data due to a 1kHz low-pass filter …read more #Accelerometer, #Adc, #Alsa, #Drums, #HackadayIo, #Music, #MusicalHacks, #Piezo, #RaspberryPi, #USBSoundCard

Two-Axis Solar Trackera
Two-Axis Solar Tracker
Solar panels are an amazing piece of engineering, but without exactly the right conditions they can be pretty fickle. One of the most important conditions is that the panel be pointed at the sun, and precise aiming of the panel can be done with a solar tracker. Solar trackers can improve the energy harvesting ability of a solar panel by a substantial margin, and now [Jay] has a two-axis tracker that is also portable. The core of the project is a Raspberry Pi, chosen after [Jay] found that an Arduino didn’t have enough memory for all of the functionality that …read more #2015HackadayPrize, #Efficiency, #Energy, #HackadayIo, #Harvesting, #Latitude, #Longitude, #Panel, #Photovoltaic, #RaspberryPi, #Solar, #SolarHacks, #Sun, #Tracking

Hacklet 52 – Breakout Board Projectsa
Hacklet 52 – Breakout Board Projects
Starting a design with a new part can be hard. What power supply voltage(s) does it need? Are there any support component requirements? What is the footprint? What about the I/O voltage levels? Breakout boards are designed to answer all those questions for you. Breakouts help when you’re designing with a new part – be it a microcontroller, a sensor, a motor driver, or anything else. They also are a huge help when you’re trying to knock out a quick hack, and just need to get something working quick. Fast to integrate, often breadboard friendly, breakouts just make things easier! …read more #Breakout, #BreakoutBoard, #HackadayColumns, #HackadayIo, #Hacklet, #TheHacklet

Racing The Beam With Super Hexagona
Racing The Beam With Super Hexagon
Early game consoles like the Atari 2600 had a very, very limited amount of RAM. There wasn’t even enough RAM for all the pixels on the screen; instead, pixels were generated by the CPU as they were being drawn. It’s playing with scanlines and colorbusts with code, something we’re now calling. ‘racing the beam’ for some reason. [Sam] is in the middle of an EE degree right now, and for a digital design class he needed to write some Verilog. At the time he was addicted to the game Super Hexagon, and the game mechanics are simple enough for an …read more #AlteraDE1, #FPGA, #HackadayIo, #Hexagon, #Pipeline, #Pipelined, #RacingTheBeam, #SuperHexagon, #Superhexagon

Use A Lamp To See Into The Futurea
Use A Lamp To See Into The Future
We’ve heard of magic lamps before, but this one is actually real. [Alex] has created a wall-mounted lamp that can tell you what the future will be like; at least as far as the weather is concerned. It is appropriately named “Project Aladdin” and allows you to tell a great deal about the weather at a glance as you walk out of the door. The lamp consists of twelve LED strips arranged vertically. The bottom strip represents the current hour, and each strip above represents another hour in the future. The color of each strip indicates the temperature, and various …read more #C, #Forecasting, #HackadayIo, #HomeHacks, #Java, #Lamp, #Led, #LedStrips, #Weather, #WeatherLamp
