Sexy 6 AXIS ROBOTIC ARM. Well I finally did it. I finally pulled the trigger and started to build a 5/6 axis robotic arm. This is an ongoing project so please check back from time to time to look at the progress and offer any ideas you might have who knows I just might include the changes. I have alot done so far. I will try to make this a step by step. If any of you need clarification or just more info on how i did that or where do i find that bit of software or that part etc. just drop me an email. If I win the Laser cutting machine. So to begin with any robotic project no mater how complex you must plan, plan, plan, and then finally figure out or layout how you will go about it.. or "PLAN"... You're fingers hands and other appendages will lose any battle you engage in with a cnc, lathe or most power tools. Now That the safety brief is out of the way lets get on with the show. ROBOTRONICA [Fuente regulable LM317]

Inicio Busca La placa de circuito impreso (PCB) ó el KIT completo listo para armar en nuestra tienda On-Line.

Fuente regulable LM317 En esta oportunidad te traemos una fuente regulable con una precisión de 1 centivolt, la cual es muy practica para circuitos analógicos en la que el voltaje de alimentación debe de ser precisos para los cálculos con transistores, circuitos resistivos, amplificadores operacionales, etc. Este equipo no debe de faltar en tu laboratorio y por el diseño resulta bastante económica en comparación con fuentes de alimentación profesionales. La regulación de precisión (1 centiVolt) se logro agregando un potenciómetro multi-vueltas (trimpot) en serie con un potenciómetro normal de 5K, el cual hace la función de regular el voltaje de algunos centivols al rotarlo, y en donde el principal componente es el tradicional regulador positivo LM317 en encapsulado TO-220. Explicación del circuito El transformador T1 reduce el voltaje de la red eléctrica a 24VAC. Esquemático: Developing a LED & Motion installation — Interactive Matter Lab. You may know that the whole spring and summer has been a bit quiet over here at Interactive Matter.

And again for a reason. I was asked by a friend to build the electronics for a massive LED installation for the ‘Hsinchu Biomedical Science Park Exhibition Center’. The result was very impressive: An 10 meter long installation, consisting of 30 moving triangles with controllable RGB LEDs in them, acting as a moving display. A XMOS controller driving 60 stepper motors, with about 100 meters of HL1606 digitally controlled LED strips composing a moving LED matrix of 30×102 pixels.

The concept and design was done by Taiwanese partners. Driving the HL1606 LED strips As every big project it all started as a very small and manageable looking proof of concept: The basic idea was simple: The XMOS XC-2 kit has 4 processing cores, three of them having two 12 pin connectors. Driving the stepper motors But finally it was done, only to learn that there was a mistake in the MCP23S08 footprint.

I used two Allegro A3953 IC-s to drive the two coils of the motor. The motor is actually a 6-wire motor, ideally driven with a unipolar driver. But as I don't have that I just used halves of the coils and ran it as bipolar. I got this motor off ebay. It's a 400-stepper, very small, cost me 8€ including shipping. 2009 » April. Mini CNC Day 5 Put in drive screw for Z-axis and mounted a stepper motor for direct drive. I am a bit concerned about whether or not the stepper has sufficient torque for direct drive. I will not know for sure until I finish the controller. Started work on the dremel/cutting tool housing. Mini CNC Day 4 Built linear rails for Z-Axis translating stage, which was by far the most time consuming to design and build of the three. Mini CNC Day 3.
