Hi @Nink, I like your design.

I'm still pursuing using the Roomba battery to power everything and will let you know how that turns out... using step downs for 7.5v for EZB/servos and 5v for iPad

@Nink,

Lumberjack time ?

Pico projectors: https://www.bhphotovideo.com/c/search?setNs=p_PRICE_2%7c0&Ns=p_PRICE_2%7c0&ci=25905&srtclk=sort&N=3869999823&

500 lumens are not cheap.

I'm curious how usable are the projectors $100 and below.

I found this: https://www.amazon.com/dp/B074QK249C

Thanks @ptp I had 50 Lumen Optima but could only watch in the dark and bulb eventually died (Not worth replacing) I like the AAXA and the M5 / M6 look especially bright. The P300 looks like it should be a good compromise. I will read user manual and reviews, they are a lot more expensive in Canada $407+ Tax is cheapest https://www.amazon.ca/gp/offer-listing/B074QK249C/ref=dp_olp_new?ie=UTF8&condition=new

Hi,

Thanks to everyone on this project. I upgraded to work with Alexa and added mobile interface. I will do more as time permits.

The Alexa integration was done using web interface and ISY 99i. I use ISY to control all lighting and sensor at home. I have the ability to access X-10 and INSTEON now and it can be upgraded for others. I also use for outside X10 sensors which send text alerts but also can send commands to robots. Currently InMoov reports on sensor activity.

If you run on PC and then look at mobile interface, it will show you Roomba Voltage. On a previous post I showed that I added a MP1584 DC to Dc converter inside V4 to control high voltages from Roomba charging.

I uploaded a video to you tube. More suggestion appreciated. I am have some issues with playing songs to Roomba. I get some but crash Roomba sometimes.

Hi Jack, Thanks for sharing the video... very nice

I'm not sure if you saw this in a previous post, but here is the link to the full Roomba interface spec

www.irobot.com/~/media/MainSite/PDFs/About/STEM/Create/create_2_Open_Interface_Spec.pdf

in reagrds to the playing a song issue, here is some sample code that I use

uartWrite(0, 1, 140, 0, 4, 70, 10, 70, 10, 70, 10, 65, 60) # load song
uartWrite(0, 1, 141, 0)  # play song

Please share some details on how you accomplished the Alexa-Roomba interface. I previously used IFTTT to handle the Alexa EZB interface

Regards, Frank

Hi frank,

Thanks for the code.

I use ISY 99i controller with network interface. This controller gives me the ability to control all lights, X-10 and Insteon. It can handle ZigBee and ZWave too but I don't use either.

It interfaces with Alexa so you can use through the web. It also can send commands to a web page so I send http://192.168.1.122:90/exec/?password=admin&script=ControlCommand("clean",ScriptStart) to start Roomba ro run that script and http://192.168.1.122:90/exec/?password=admin&script=ControlCommand("stop",ScriptStart) to run that script

You could do this through a web page also.

But this gives me huge flexibility. I can start something at a certain time. I can read in X-10 sensors, send a command to EZ Robot and turn on lights etc.

I guess you can use IFTTT but this works for me internally.

I have many other programs ISY handles like sunrise and sunset routines etc.

BTW - That demo runs on Roomba battery with DC-Dc converter I told you about the other day.

Here is link to this unit on amazon.

ISY99

Takes some work and add on modules but it does a lot of automation.

I am not sure we can send web commands from EZ V4? that would be great if possible.

Let me know if you have any more questions.

Jack

Hi Jack, Thanks for all the great info

The sending part from Alexa looks very similar to the one I wrote up in this tutorial

If you are looking for a way to send events from EZB, take a look at the plugin I wrote for IFTTT

Thanks again, Frank
