My rotating tower for Golias V2 has a new motor. I finally found the right motor to be used, a motor of an electric window of a Ford car. Stepper motor is so good but generates a lot of noise and vibration in low speeds. It was necessary to reduce the speed of the new motor with PWM. The mechanical coupling is so easy. I'm programming a PIC processor to operate the tower with its rotation motor, two servos and other devices as a spot light, infra- red light, a video-quad to select between four cameras and much more.

I finished the loader of my coil gun. The trigger circuit and load solenoid works great. My rotating tower for Golias V2 had problems now, I finally found the motor to be used. I´m using a stepper motor, but I am still with problems of mechanical coupling. I think that I need to live in a planet that had more than 24 hours in a day. 8)

I´m back. I´m mounting a coil gun for Golias V2 with two stages, capacity of ten shots and a laser aiming (red and infra-red laser). A not lethal gun, only for demonstration purposes and I intend to install a PIR sensor to protect life forms. I finished the upper cover lacking only the painting. I´m initiating the rotating tower. Golias V2 is growing...

Today I finished the aluminum panel to fix the keys and fuses. They are 4 keys and 11 fuses. I came back toward the paper and I drew the wiring for the new panel.

I started the wiring work, now I go to cut an aluminum plate to make the internal panel of keys and fuses. With the new panel I will be able to finish the wiring of the mobile base of Golias V2.

Today I fixed the boards of hbridges in its new places. I had that to retouch the painting in some points. Everything soon for the wiring now.

Today I changed the distribution of the boards of the Golias HBridges. When I prepared the wiring I came the new idea of where they would have to be fixed and this saved much space and electric wire. The wiring was stops after fixing the boards again.

Finally I finished the painting work. Now, I start to install the mechanics and the power sources and hbridges. I intend to test these systems in the next Sunday.

I finish the two power supplies, one with "clean" power for logic circuits and other for motors and drivers. Golias V2 have a single battery for circuits and motors. I finish and test the hbridges, I made it with extra amps and good snubber circuits. I dislike noise in my power lines!! Today, I begin the paint job of Golias V2 body (mobile base only).

My new robot called Golias V2 is under construction. I have new photos in my home page.
