Hey there !
I am a professionnal industrial programmer since 1993, present on Linkedin if you like to use this social network : Luis David Campos Venancio .
My service consists in :
-
3D-Printing up to 40cm high !
-
Modeling ANYTHING !
-
Programming ANY 3D Program !
On this website you can find my open-source projects as a maker and open-source supporter and contributor, which are totally original and uniques. Like I say : "Never seen before".
Also there's a selection of the BEST WWW OBJECTS, based on 11 years of exploration, some I 3D-printed, some others I didn't 3D-printed yet, but would like to; like the Ultrascope.
The LINKS section is constantly evolving and I just added the Arduino section a few days ago.
I'm waiting for people in the FORUM page, so don't hesitate to register ! You are welcome if you want to post a request or ask me a question in public if you feel it can help me and the public, otherwise, you can send me an e-mail to keep our conversation private.

I Started 3D-Printing in Toulouse, France in January 2013, at the Tetalab (an association hosted by the Mix-Art Myrys collective) where I learnt everything around REPRAP 3D-Printers melting 15Kg of PLA that year.
This was a ULTRA-SUPER-COOL EXPERIENCE. I LOVED EVERY DAY THERE. I was in the THSF staff several times, made some RepRap demos, talked on radio at "le bit et le couteau" and for Radio Campus Toulouse talking about MATERIEL LIBRE aka Open-Source Hardware (not warez !) . >P

2013 to 2016 : I worked for Tournefeuille Mediatheque organizing workshops about open-source hardware (Arduino and RepRap) and software (Blender3D). MEMBER of Toulibre.org .


2017 to 2022 : Changed to Portugal where I sold many objects in festivals like FREEKUENCY 2017, Festival das Cores 2018 (Vila nova de santo andre) and even at the beach for tourists and friends at Melides restaurant "Ar de Mar". I was also present at Festival Musicas do Mundo 2018 and 2019.


As the weather in Portugal is very hot during summer, I even 3D-printed outside and sold many custom objects, or small series prepared at Santiago.

I had a Renault Trafic (with one f yes) van equipped with my 2 RepRaps, plugged, with a 30 meters extension, directly to the restaurant 220 volts. (I still have the Van for fun)


During the COVID19 lockdown : Selling objects stopped working by lack of visibility. But I published an open-source breathing-mask on GitHub and Stop-Postillons.Fr !
2022 : Pause for financial rebuilding, learnt to be a Forest Fireman (aka Sapador Florestal).



2024 : BACK TO 3D-PRINTING !
I'm on more than 30 years of experience in computing since this year.
My diplomas are authentically from France, Versailles region at the Lycee Technique Agora - city of Puteaux (92000). I have them on paper if you want to check them or better CALL THEM and ask if they had a student called David Venancio. I have been one of their best students and got 17/20 in Mathematics, and 19/20 in technology, 15/20 in english for the Baccalaureat diploma.
The two years following my Baccalauréat were for the B.T.S. -Brevet de Technicien Supérieur- in Industrial Computing where I learnt ASM, C++; installed SCO Unix for PC (a kind of Linux ancester and a UNIX system for IBM Personal Computers).
Also a very important event in my life during this B.T.S. : 2 months at Lotus Development S.A. learning Lotus Notes Version 3 (the first intranet, all incorporated, first development plateform for Intranets and Groupware inventors). Lotus tagline was "Working Together" !
Please note that I'm a developer (or programmer if you prefer the term, "developer" not as in real-estate ! I develop "apps"), coding when necessary in various languages ! C/C++ (Windows or Linux), Javascript (using tree.js and jquery if needed), PHP (from scratch or with libraries), SQL for databases (postregSQL or mySQL and even other systems).
My diplomas : Electro-technician and Industrial Computing Superior Technician :
You can order objects up to : 30cm x 30cm x 40cm


Also known as "Meta_4", in video-games (playing Arma 3 KOTH Mod), and generally speaking on internet, this is my actual nickname ("pseudonyme" in french, "alcunha" in portuguese), which I changed to reflect my new life in Portugal.
Professional Programmer since 1994, freelance since 1997 with some pauses like 1999 when I co-founded the ESWC ancestor : "LAN-Arena" (as "Meta-B")
I have developed a loooOOOOoooot of websites, intranets, extranets, C and C++ programs, as a PAID SERVICE for many companies.
Moved from Paris in 2010, went to live in Toulouse with Mathilde F.
Then in 2017 I changed to SANTIAGO-DO-CACÈM, which is a wonderfull small city located 150 km south of Lisbon, close to the coast.
Feel free to contact me at anytime and leave a message if possible or send me a complex question by e-mail..
I love critics and suggestions. Thanks You !
I discovered not long time ago this manifesto which I'm fond of :
https://criticalengineering.org/
So with this in mind (which still can be criticized) :
- I use PLA and do not 3D-print with petrol based plastics (only PET from time to time if there is no choice),
- I published objects with Creative Commons Licences on GITHUB,
- I'm working on a modular vertical wind-turbine,
- My Anti-Loose Phone project is about programmed "destruction by the client".
- I am working on a open-source hardware Paper Printer (not on Paper, without ink) actually under prototyping.
I do quite a lot of Research and Development. If you are a maker or like R & D don't hesitate to join my discord server shown at the bottom of this site.
