New LEGO Hardware Standards:Boost, Mindstorms Inventor/Spike

So LEGO has a new set of electronic hardware (standards).  They are apparently not compatible with the previous generations of Mindstorms.  Of course, that may be adjusted with some *ahem* modifications.  I'm thinking especially of the sensors.

I'm going to check out the Boost set (out for a couple of years), which is blutooth compatible, and it's interface plugs are compatible with the new Mindstorms Inventor/Spike (educational variant) which came out late last year (2020).  Apparently there were roll-out problems due to the pandemic.

All of the new hardware seems to largely run off of applications from smart devices.  Boost is apparently presented as a mostly remote control type of affair.  However, someone in that community has found ways to expand the programming capabilities, and that made me think it was worth a look.

Though there is currently a limited sensor set, LEGO has combined functions into single sensors.  One sensor is a combination touch (on/off button) and force-level (pressure) sensor.  Another is a light/color and distance sensor (IIRC).  These combos are both possible possibly wonderful and terrible.  A sensor multi-plexer sure would be nice.

I have a Boost kit also, and am interested to hear what you learn.

Power Functions-to/from-Power Boost Adapters

Well, this outfit in Britain has adapators for using old Power Functions motors and lights with Power Up hubs (trains and the above mentioned units), and vica-versa.  So that's a start in the right directionAccessories | PV-Productions (pv-productions.com)

 

Oddly, they made a LEGO Technics compatible (shape, not so much electronics) record needle.  I suppose one could make a Mindstorms jukebox or victrola if they had the desire.

Python to Blutooth, Scratch Language

Apparently programming in Python can be used to control both the Boost and PowerUp bricks/hubs.

Also Scratch can access the Boost.

LEGO Wireless Protocol 3.0.00 documentation

So the Boost (as well as the WeDo 2, DuploTrain , & PowerUp Hub Devices)  is communicated with by Bluetooth with a protocol that LEGO has shared and is posted on GitHub here:LEGO Wireless Protocol 3.0.00 Doc v3.0.00 r17 documentation

 

There are some very nice and potentially powerful features built-in to some of the hardware, like battery power level reporting and tachometer readings for motors that have them.  The list is long.  It seems that the concept was to save money by having the user's tablet do the heavy lifting (computing power-wise) versus putting a computer in the control brick.  That's an educated guess.Apparently others have used "bluetooth sniffing" to detect command access to the device.

You should have a look to the Chinese improved Version EV5. Far advanced over LEGO.
