Moved to Barcelona

Well it was hard, frustrating and a very tiring experience to say the least. But after finally signing a one year Contract for the apartment, and many “Nos” for other’s we’d liked, but we didn’t qualify since we do not have any spanish work…we are settling down nicely and already got high speed internet installed.
Now is time to keep on developing working for future electronic projects and contributing to the open source community.

EPDiy developer updates is being posted regularly on my twitter timeline

EPDiy S2 PCB is still on development

High voltages are running already but there are still some minimal updates that are waiting for my interaction.

Is ready to be tested and results will be posted here soon.

Espressif ESP-Mesh updates their App with a new UX

About a month ago I started learning to use ESP-IDF and got very interested in Espressif Mesh Lamps. It’s a lot of fun for me to create my own ESP-Mesh LEDs lamps with this technology. But as with everything I touch that is open-source, apart of being a user, I try to collaborate and made the thing better. That’s the spirit of open source, you are a user, but also at the same time your opinion counts and usually it’s welcomed.

Comparison from previous ESP-Mesh App and new upcoming version:

2018 version
Esp-Mesh App
03/2019 new version

Updates resume

  • More integrated and compact UX. Now On/Off switch is in the same screen allowing for easier usability
  • Doing White with RGB is now possible. Click on the center and the light will turn on the 3 colors at the same time (New feature)
  • Warm/Cold switch is also better signalized and more usable.

I really like the update and I think is a significant improvement over the last version.

Here some selfish pictures of my last lamp projects ;)

FS2 camera from Blender to production

In this entry, I wanted to document what is the process of making one of this cameras, starting from the 3D – model to the end product where you turn it on and connects to WiFi ready to take pictures.

After removing the support and sanding the round columns the first thing is to connect the front and back case together and see that they fit correctly. Usually, they do but PET is a tricky plastic to print and the end termination is a bit rougher than with PLA so it requires some post-production work. As an advantage, this plastic is stronger than PLA, and will stand a crash much better since it’s more elastic and resistant. I would say the best termination and strength balance would be to print this in ABS but I dislike the smokes and the fact that is also very difficult to print at home.

When this step is ready then it’s the time to heat up the soldier and prepare the ON/off switch and the shutter button. Then there are 8 cables more that go from the Arducam (2 or 5 mega version) to the Wemos D1, that is the responsible of uploading the picture to the cloud. This is a prototype for myself so it looks a bit messy but shows how it is at this stage:

3 pair of cables from the left to the right: Battery, ON/off and shutter button

Then comes the reality shock moment that is to connect the Wemos ESP8266 through USB to the computer and upload the program that will do the magic of receiving the JPEG image from Arducam and upload it to a php API endpoint. Usually, at this point there is something that needs to be corrected, but either nothing works or all is fine and dandy. I open the mobile hotspot and turn on the camera. See if connects, try to take a picture, preview it on the PHP-gallery.  Try to test timelapse mode, see it works, and that’s pretty much it. A new camera is ready to be delivered.
