Carambola SoC Stand Alone with MSP430 Piggyback

Like I wrote in this article, it is pretty easy to run the Carambola SoC stand alone. Today I finished the Carambola-MSP430 (for MSP430 stand-alone see this article) Piggyback I intend to use as a replacement for the current jumper wired brains of my Carambot. The Carambola comes with 2mm pin connectors, I used a […]

Carambola SoC Stand Alone

I just was playing around a little running the Carambola SoC stand alone (without dev-board). The picture blow shows what needs to be connected to boot the Carambola, access it through serial line (by using a TTL USB to serial converter), and optionally connect USB (I used a web cam): Some notes about power consumption: […]

Installing a Propeller Tool-Chain for C and SPIN

Lately I started playing around with the Parallax Propeller Quick Start Board. Since I found it a little hard to puzzle together a Linux tool-chain supporting C/C++ and SPIN development for Propeller on Intel based as well as on ARM based machines, I wrote a little installer script which helps in setting up a tool-chain […]

Hallo Carambola

Today I got my Carambola boards (thank you Matze). The Carambola is a MIPS based SoC from 8devices. It uses the Ralink RT3050 which includes a high performance 320MHz MIPS24KEc CPU core, 8 MB Flash and 32 MB RAM. The device also provides two Ethernet ports and w a 802.11bgn radio. And best of it all: it is […]

A Modern Linux System …

.. like Xubuntu is a great thing. It allows you … OK, we already head this before, so I will get to the point: Why are all Linux desktop distributions sucking so much nowadays? Today I had three moments of „what the … happened to Linux?“ within only one our …

The E-Big Jake hack made it on hackaday.com:

Finally: E-Big Jake

Today was the day where we decided, that E-Big Jake was ready for a ride. We checked the tractor with a throttle of 1/3 of what is possible. This resulted in  a child friendly 5km/h speed. We also gave a throttle at 2/3 a try, and we got a speed of about 15 km/h. I […]

E-Big Jake’s First Drive

OK, I received the new motor controller (a 24v23 this time) and I managed to roughly hack the toy tractor together so that it is able to drive on it’s own wheels. Very hackish so far, and improvement is needed, but the tractor easily was able to drive me through my shop (since it is […]

Getting Closer …

Big Jake (the toy tractor) is now almost mutated to „Electric Big Jake“. The build seams fairly stable (tractor was able to carry me), and I managed to put back the top cover on the tractor. In the movie you see „Electric Big Jake“ test-driving on a stool (I was only giving about 1-10 Volts to the […]

Tractor Update

Here is a short update of the e-tractor project. I managed to mount the motor, add a hall sensor based throttle to the motor controller , and, … well … , OK damn! I fried that motor controller :-(. And no, everything was wired correctly, it was just stupidity: When I was testing the throttle with the motor, the controller […]
