My office is quite cluttered with hardware. I’ve been toying with chiplotle lately but doing so meant cleaning up my desk and make room for the big clunky 80ties plotter. Chiplotle just sends serial commands, so why not over bluetooth. I ordered a
I lost connection with the mi mini wifi router after following this procedure. I flashed u-boot to the bootloader, and it succeeded, but It would no longer boot the firmware.
Apparently it did boot into u-boot, but to find that out I had to get a serial console. Instead of getting a usb serial to TTL I tried using a raspberry pi and the GPIOpins. It worked.
opening the MI mini wifi
two screws hold i together, opening it from there was a bit harder. You have to forcefully get underneathe four little hooks at the bottom front of the device
after opening it, all we need is accessible.
soldering a serial port on it
I used an old connector I had lying around, easy t get to the breadboard
next step involves the RPi
you can then hook it up to the RPis Tx, Rx and GND pins. As both devices use 3v3 TTL, no extra circuitry is needed
ssh over to the RPi
once your logged in, type
$ minicom -b 115200 -o -D /dev/ttyAMA0
to start a serial console on the RPis GPIOports. Once it runs, boot the mi and you should see this
now the easy part
connect a UTP cable from a LAN port directly to your computer, and assign your PC a manual address in th 192.168.1.x but not 192.168.1.1
Shot using an old but descent RolleiFlex clone that didn’t have a stop for the film, so I overlapped all frames. I could never cut the film after developing it, but I liked the results. I also learned how not to double expose the film…
I hardly have time lately to code anything at home. I just dusted of the APC and I made slight progress going almost no sound to some sound…
That is in “dongle” mode. In stand alone mode it works fine. I even added a set of capacitors so you can switch between several sorts of sounds and a light sensitive resistor for that look-without-touching-I-can-play-this-APC-touch
I was successful in attaching it to the computer with the regular standard arduino’s + firmata and playing it from puredata.But this is an arduino pro mini (5v 16Mhz, from sparkfun). Apparently firmata isn’t entirely the same on these mini’s. Although Since arduino 0017 I can connect and send data, it’s not without errors. First of all
Is what I see when I try to run the pd patch. lot’s of those, thousands…
Another weird thing is that even though pin 13 is unconnected on the arduino, It’s the only pin that seems to work. I really don’t get it. Is there some sort of different mapping? normally only pin 9-10-11 are supposed to work.
Axiome is a mlr (monome style) pd patch. I’m still looking for a good beatslicer to built my own custom controller. This one is a candidate for sure. Provided I still don’t own a monome, I will have to hack it up so it becomes compatible with my yet-to-be-designed-budget-friendly-midi-and-osc-controller. Lucky it’s GPL’ed
