Horseshoe house

The inspiring Grand Designs series county Antrim 2015, showed the beautiful home of Michael Howe of 2020 architects design for the renovation of an old forge.
This got me thinking, resulting in the following rendering, also shown on youtube,

Solar VW combi, Solar Renault Trafic

1966 VW bus goes solar LINK
Read the story, as he has some interesting things to say.

Below some pictures and some 3D renderings of what he has done with the VW combi ( app 1.170 Wp) and what could be done with a Renault Trafic van with 2.340 Wp of panels. All within regulations.

Hope to inspire.

My renderings of the VW combi show the immense area of the panels. Looking at the photo's he used 9 panels of 130Wp. Panels of 1482mm bu 676mm are available, 4 base-cells wide.

Renault Trafic, is pretty wide and boxy so well suited for conversion. The 2.380Wp of the panels would on a sunny summers day easily allow driving in a town and a battery pack of 15kWh could be charged in a day. Interesting numbers.
The Renault Trafic is cheap second hand, and with a conversion to electric, one would not have to bother with the quality of the motor, which would probably be in bad shape as the Trafic is a typical builders van..

Regulations even allow for much longer roof panel rack, ie 3.5m in front of steeringwheel center and 5m aft of aft axel. I did the drawing, looks/feels not OK.

This solar Renault Trafic is within the narrower limits of the law. One meter in front of and one meter aft of the vehicle. Still looks pretty impressive (and impractical?)

St klaas surprise, side-table cube

We have a family tradition of making nice stuff for each other at St Klaas, this year I made the following, a table cube of two side tables. maybe it will get you thinking about making something for someone else.

On one side is written Marianne Williamson's beautifull text:


'Our deepest fear is not that we are inadequate
Our deepest fear is that we are powerful beyond measure.
It is our light, not our darkness that most frightens us'

We ask ourselves, Who am I to be brilliant, gorgeous, talented and fabulous ?
Actually, who are you not to be? You are a child of God. Your playing small doesn't serve the world. There's nothing enlightened about shrinking so that other people won't feel insecure around you. We are all meant to shine, as children do. We are born to make manifest the glory of God that is within us.
It's not in some of use, it's in everyone. And as we make our light shine, we unconsciously give others permission to do the same. As we're liberated from our fear, our presence automatically liberates others.

Thermik XXXL

Full house eclectric glider.

My new Challenge:
Thermik XXXL  (Schiemer / Valenta link to baubericht ) is my new challenge in flying and building. at the moment I started with the wiring harness for this full house glider.

Spektrum (website)  DX9 DSMX  transmitter with AR9020 9-channel receiver, with full telemetry TM1000 DSMX,
8 Hitec (website) HS-5125MG ultra flat wing servos and Hitec elevator and rudder servo's .
Hacker (website) B50 XL 6.7:1 with X-70-SB-Pro 2.6S speed controller, Topfuel LiPo 30C 3400mAh 6S, CFK-Prop RFM 23x12, Spinner RFM 40x6mm

Wiring harness:

Made two versions of the wiring harness the first to test and setup the transmitter receiver, servo, telemetry system. The mixing of the servo's was also done this way, easy to see and do (even with the left right swap as I used a looking up to the wing viewing direction.
The second version with all the wires to be installed in the plane and the wing fuselage connection, a 25 pin version, to allow me to later change to a system where all ailerons can be controlled seperately, now the spoilers and inner flaps are on a Y-wire harness. One servo in each Y-harness reversed.
