Re: Projector power controlled by Raspberry

Soldered in a tiny board and working perfectly in a Jetson Nano. :D I had to quit about using the Raspbery Pi due to the complexity of implement in it an on/off button for switching the whole system on and off. It's easier in the Jetson Nano, but I'm having lots of problems with Processing software ...

Re: Projector power controlled by Raspberry

(I forgot to talk about one step: before I soldered, I used the multimeter as PhatFil said and I realized that the two soldering pads where the ones that I have to use. Thanks, PhatFil!!!!) --------------------------------------------------------------------------------------------------------------...

Re: Projector power controlled by Raspberry

Hi all! I was very afraid because for following the advices from PhatFil and Brandon92 to test the solderpads I had to take out the cover that was in the opposite side to the switch side and try to push the board to take it out. I was very afraid that the optical system could move and lose the proje...

Re: Raspberry + WittyPi2 + picoprojector DLP2000

It's impossible for me to move the serial port to the pins of the USB UART that I have connected to the Raspberry Pi 3B+
I think I'm gonna quit from this project. It's like hitting a wall with nude hands over and over again.

Adding an extra TxD pin on RPi3B+

Hi! I need an extra TxD pin for my RPi3B+, so I bought a CHG340 USB UART device for connecting it to the RPi USB port and having one more TxD port: https://www.amazon.es/gp/product/B07LCFVDVZ/ref=ppx_yo_dt_b_asin_title_o03_s00 I was trying to install the drivers from https://github.com/aperepel/rasp...

Here is another image of the whole picoprojector. The Cube Rif6 is a tiny device, its dimensions are 5x5x5 mm or 2x2x2 inches.

Projector power controlled by Raspberry

Hi! I have bought some Cube Rif6 picoprojectors for my project, which includes a Raspberry Pi for sending the moving image via HDMI cable (in this case). As the Raspberry Pi has 5V GPIOs (it is what the picoprojector needs), I will power it from that pin. The picoprojector has a small push button fo...

Re: Raspberry + WittyPi2 + picoprojector DLP2000

Thanks a lot, rpdom.
I have bought this USB device, hoping that it will work with the system:
https://www.amazon.es/gp/product/B07LCFVDVZ

I will receive it in 20 or 30 days. I'll post describing the process if I succeed.
Thanks.

Re: Raspberry + WittyPi2 + picoprojector DLP2000

As "dtoverlay=dpi18" makes that GPIOs 0~21 are occupied by DPI output, I2C and serial interface will be invalid. WittyPi2 uses I2C interface to talk to the RTC chip, and it detects system shutdown by monitoring the serial TXD pin. So, there could be some problems because they are lines that the DLP2...

Raspberry + WittyPi2 + picoprojector DLP2000

Hi! I connected my Raspberry to the pico-projector DLPDLCR2000EVM with no problem for an artistic project, following the instructions that I read in the Frederick Vanderbosch website (http://frederickvandenbosch.be/?p=2948), but I need to add an on/safe shutdown button. After some problems trying to...
