bodyFor the human interface with Stepper Motors we have designed two solutions. The <a href='http://lechacal.com/wiki/index.php/Stepper_control_v3'>StepperControlV3</a> and the <a href='http://lechacal.com/wiki/index.php/Stepper_UNO_v1.0'>StepperUNO</a>. Both of them have buttons and potentiometer for physical control of the motor. They also embed an Arduino microcontroller for the pre-user to configure each button's behaviour. <h1><a href='http://lechacal.com/wiki/index.php/Stepper_control_v3'>StepperControlV3</a></h1> ![IMG_1135_small.png](https://steemitimages.com/300x200/https://cdn.steemitimages.com/DQmRjkTrfuoVEgCCHKgZ2i9nVcrhtVucJh8J476c9cbcin3/IMG_1135_small.png) This is the smallest option. It operates a single motor. Two versions are available. One for the A4988 driver the other with a Generic terminal screw to connect to any driver. The microcontroller is an Attiny84 which is programmable with the usual Arduino IDE. This a very handy board to have around if you come to test or manually operate steppers. <h1> <a href='http://lechacal.com/wiki/index.php/Stepper_UNO_v1.0'>StepperUNO</a></h1> ![IMG_1462_small.png](https://steemitimages.com/300x200/https://cdn.steemitimages.com/DQmUYuiRKJb16D7RktFuJQis8BgRt8v95QTKyMbsSWm7XeU/IMG_1462_small.png) This is a more complete solution. The stepperUNO has 2 motor outputs available with both A4988 and Generic driver. The microcontroller is the common Atmega328 found on the Arduino UNO. Easy to program directly via the USB port. It also embed one attiny85 controller for each motor to allow smoother control of the motor. Human interface is using a mass produced LCD-keypad shield. It features six push button and a 16x2 LCD screen There is also a potentiometer for speed control for example. This is an excellent solution for controlling 1 or 2 axis systems with human interface and automation.

bodyIf you are looking to monitor your home energy usage using open source component lechacal.com has built it. (https://steemitimages.com/300x200/https://cdn.steemitimages.com/DQmRJtTkW3adtcG3Pt2sbtexepvLQXM35eGdVEfqfHw1wby/IMG_1521_small.png) Many solutions are offered to record electrical usage but most of them are closed source and will not allow you to own the data. You might know your stuff with database and data analysis and prefer using tools that allows you to manage yourself what you do with the data. Several platforms exist to record the data and graph them. We normally call them timeseries database. To name two of them that you can install on your own server or use online are <a href='https://emoncms.org'>Emoncms</a> and <a href='https://www.influxdata.com'>Influxdb</a>. <a href='lechacal.com'>LeChacal.com</a> has build several devices to post data to these type of servers. The easiest one to use is certainly the <a href='http://lechacal.com/wiki/index.php/EMONWRT3'>EmonWRT3</a>. It runs with OpenWRT. Yes a Linux device! Easy to configure with a web interface. Data forwarding to Emoncms and/or Influxdb are directly integrated. Now you might prefer to have your own code running to populate data your own way to your infrastructure already in place. Then there is also the option to use a Raspberrypi and use one of the shield that goes on top. Then you can run C or Python code to read the data as they come. We have created the <a href='http://lechacal.com/wiki/index.php/Raspberrypi_Current_and_Temperature_Sensor_Adaptor'>RPICT Series</a> shield for Raspberrypi. They come with different number of port for Current Sensor, Voltage Sensor and even Temperature. ![emoncms_front.png](https://cdn.steemitimages.com/DQmQzfaD513JNT9eFJ1sxSwps8XCSSqNF2N858rPgFtdGju/emoncms_front.png)
