smart controller evolution … v2 coming soon

we ran into production related challenges and had to reconsider numerous scenarios. we pivoted some and our new v2 smart controllers boards are just about ready. v2 comes with inbuilt linux microcomputer controlling an atmega2560 microcontroller, 20+ digital sensors, 10 analogue, 3 uarts, i2c, 12 relay controls, wifi, eth, mini sd-card, usb(video, audio, cellular), watchdogs, arduino compatible, etc.



Heartbleed openssl bug … v1.3 smart controller patch

Our smart controllers were running a version of openssl that was affected by the heartbleed bug consider ‘the biggest security vulnerability of all time’ as an attacker can remotely connect and steal encryption keys or data from processes in memory. Our production and development servers were not affected as they run older versions of openssl. However the earlier v1.1 and new v1.3 smart controllers were running a vulnerable version of openssl. It should generally not be an issue as the controllers are probably behind a firewall. To see if your controller was affect, connect to your device using ssh as […]


diy aquaponics class review – by jason axt

Jason Axt from Sweet Water Foundation took my DIY class the other day … this was his feedback. In my defense – I had 2 nine year old’s in  my classroom as I  did  among others Kamal Hyder the author of ‘ ‘embedded system design using the rabbit 3000 microprocessor’  - tough range to keep engaged. —— Aquaponics Class Kijani Grows: Eric Maundu American Steel Studios 3.8.2014 10am – 4pm   Review: The class itself started with an overview of how the natural ecosystem deals with the water cycle and touched briefly on the nitrogen and carbon cycle without real […]


aquaponics and squares

The year is in full swing and we are back on the guns2garden project with the kids. New kids around this time as all former students are no longer in the school because: some families relocated to other safer neighborhoods, others had to change schools to makeup for lost credits, some just disappeared, pregnancies, I even lost one kid to prison. Castlemont High School in East Oakland is where we run the g2g project. I think  the url’s below can speak for themselves. http://www.npr.org/2013/12/13/250734629/for-many-urban-schools-gun-violence-remains-a-daily-reality http://www.mercurynews.com/breaking-news/ci_21603171/fight-at-an-oakland-high-school-causes-police http://www.youtube.com/watch?v=zp_QcMLbj1o http://blog.sfgate.com/cjohnson/2014/01/28/oaklands-youth-uprising-mourns-violent-attacks-on-its-members/ (Youth Uprising shares a common fence with Castlemong High School and funds the kids […]


diy classes with kijani grows

it is a very humbling experience when anyone comes to me wanting to learn see, i was the naughtiest kid in many blocks, often i got punished for not being like others and sometimes others got punished for being like me.  still, what they called naughtiness i  consider being creative. for instance, the number of times i got a physical whooping for running tests on how different windows sound different when subjected to different projectiles was say healthy.  we were disruptive even then. so,  it really is very  humbling to have students come to our space. the other fun part […]


g2g – capturing bullets silently

only after breaking down one of the sound proofed boxes from the ceiling did we figure what they really were for – to capture stray bullets without making noise. we recycled lots of stuff from the rifle range, the sound proofing materials were used in the school sound studio. one of the reasons we needed to remove the fixtures on the roof was to reduce the possibilities of mould spores incubating due to the moist warm environment expected from the fish tanks and indoor grow lighting. there were 30 pieces weighing about 80 lbs each on the ceiling for deflecting […]


guns2gardens – the early days

what would you do if  you were given an unused rifle shooting range? a fortress so to say underutilized for storage with room for so much potential we asked some students from our One School One Garden (OSOG) program at Castlemont High School in East Oakland for visionary ideas on how we could use the rifle shooting range they came up with some of the core values listed on right of the board – an ecosystem, with fresh healthy food, an escape from gangs, guns and violence that so rules the streets of East Oakland, by reusing our resources, to […]
