- off topic: I attended the Libresolarbox workshop in Hamburg, where we builded/assembled first "official" prototype of the OSE Germanys Solarbox project (A Solarenergy-Storage system with LiFePo4-cells), based on the LibreSolar BMS-5s and the UniProKit/UPKlib for framing and housing structure including "shells and skins". Before i was working on a detailed Freecad-version of the construct which helped me to learn more on how assembling works in Freecad.
Solarbox-Specs:
- 12V, 72 Ah ==> capacity: 0.86 KWh (using CALB CAM72 cells)
- Balancing: BMS-5s, based on the TI bq76920 chip, with STM32F072 ARM Cortex M0 CPU
- Solar-Charge-Controler: MPPT, up to 20A
- dimensions about 44 x 32 x 20 cm
- Inverter: Victron Phoenix 12/350
- LibreSolarbox Workshop at St.Pauli FabLab in Hamburg

- attended TorchTable Workshop online for kicad walkthrough TorchHeightCTRL pbc and Shanes kicad tutorial
Tue Oct 10, 2017
- Made Video that shows how to deploy the TorchHeightCTRL_V.02 sources from Github [1] on Kicad.
See on youtube https://www.youtube.com/watch?v=v-nhG5vuZW0
- installed and tested slack
Tue Oct 03, 2017
- installed OSE-Linux on USB-Stick and tested the KiCad installation with my TorchHeightCTRL sources
I started kicad from within the shell with typing /usr/bin/kicad, but there is also a start-icon in the left vertical menu-bar.
Then i opened the torchctrl.pro projectfile from my sources directory (which is a clone of Github repository at https://github.com/case06/TorchHeightCTRL) and everything appeared nicely in kicad, with one little exception: one has to load the 3d-library files for the 3d-viewer manually, but thats normal and has nothing to do with the KiCad-installation within the OSE-Linux.
Kudos to Christian, who did an excellent job with the OSE-Linux !!!
I appreaciated very much the fact, that i found the latest KiCad version here, and i also like very much, that FreeCad comes beside the 0.16-stable-release also alternatively with the nightly-build version (which is 0.17).
- off topic: i reworked and updated large parts of my UniProKit 3d-part-lib, which is now completely in FreeCad .fcstd-fileformat. https://wiki.opensourceecology.de/Upklib
- working on a FreeCad model of my D3D printer framing, which i can use also for other projects, like the testrig for the TorchCTRL and as structural base for the LibreSolarBox project.

- From last Thursday to Sunday evening i attended at the MakerFaire2017 in Hannover and showed there also the TorchHeightCTRL. Since i didn't found the the time before, to finish my D3D printer, i decided to use its frame as appropriate for a testrig integration. I had to made it 16 cm smaller to get it into my car ;) , which was no prob because i used components from my UniProKit, another project shown also at the MakerFaire.
- MakerFaire 2017 Hannover Germany
TorchHeightCTRL-D3D Hybrid
For a D3D printer i still have to add the motors, an extruder and the heatbed, but as a testrig for the TorchHeightCTRL its ok for the moment.
The UniProKit, my modular construction system
The OSE Germany stand at the makerfaire; the red box contains an experimental setup for my zinc air fuel cell project, where we are "burning" (oxidating) zink into electric energy and show how the zinc can be regenerated then by renewable energies.
- here my full Blog-Report about that event (sorry, text only in german, but lots of pics) [2]
Tue Aug 22, 2017
- doing preparations for the MakerFaire Hannover this weekend where we exhibit some OSE(G) projects

Tue Jul 18, 2017
CNC_Torch_Table_Z_Height_Control - working on code for auto height control.
Tue, Jul,11,2017
- made sensor-head and mounted it on test-rig
- wrote monitoring-programm (in processing) for visualizing CapSensing-data
- first test-samples measured on the test-rig with new sensor-head, see video [12]
sensor-head made from 2.75mm copper wire, outer diameter 42mm, inner diameter 32mm
whole sensor-probe with shielded coax-cable and BNC-connector
Experiment1: moving probe along 10mm in steps of 0.1mm
Experiment2: moving probe along 50mm in steps of 0.1mm
Experiment3: moving probe manually along 50mm in steps of 10mm ==> 5 distinct plateaus. Those little peaks on the beginning of each plateau are artifacts, resulting from moving the carriage by my hand.

- today i received an order from a special material filament named "Iglidur I150 Tribo-Filament" from Igus [17]. This is specially suited for 3dprinting sliding parts and is about 50 times less abrasive than ABS.
I tested it with printing a surrogat for the lm8uu linear-bearings in the universal axis. Prints nicely at 255 °C. The bushings should give less play and a lower noise-level.
