Homido VR headset

Homido, virtual reality headset

Website: http://www.homido.com/en

The Homido VR provides a low cost intro into smartphone-based virtual reality or 360º videos, and it’s more convenient than Google Cardboard. It is designed to hold a smartphone in front of your eyes so you can view VR and augmented reality content in the most immersive way possible.

HOMIDO - Original Design

The lenses are the most important part of any VR headset, and the Homido comes with three different cones to hold them in place, all made for different focal lengths (Adjustable focal lengths). On the faceplate there are two rotating knobs for adjusting the depth of view and IPD settings (Adjustable Inter-pupillar distance). Any device with a 5-inch 1080p resolution is recommended, but it’ll work with just about any phone, regardless of OS.

Homido VR is my choice as developer for any Google Cardboard and Samsung Gear apps. Unlike Cardboard, this is a solid but lightweight, complete with three lens fittings, a secure hands-free design and compatibility across most 5-inch smartphones.

Solar Home system

A small solar electric or photovoltaic (PV) system can be a reliable and pollution-free producer of electricity for your home or office. Small PV systems also provide a cost-effective power supply in locations where it is expensive or impossible to send electricity through conventional power lines, even for use in emergencies.

Because of their modularity, PV systems can be designed to meet any electrical requirement, no matter how large or how small. A stand-alone home solar electric or PV system operates "off-grid" it isn't connected to a electricity distribution grid operated by a utility.

Accurately sizing the components of your solar electric or PV system helps ensure that your system will produce the amount of power you want it to produce. This is especially important for stand-alone systems, which are not connected to the electricity grid. Because PV is modular, you can always add to your solar energy collector should you need more power down the road.

Below I introduce the technical description of my "Solar Home system" that I have build in the apartment, for the generation and accumulation of electrical energy exclusively for computer use, internet and lighting, in case of emergency in order to keep working.

"Sistema Fotovoltaico Autónomo" (Spanish) Resource links database:

https://sistema-fotovoltaico-autonomo.zeef.com/es/marco.romero

"Sistema Fotovoltaico Autónomo" es una base de datos web de enlaces, que es una plataforma abierta colaborativa donde se puede acceder a toda la información relacionada al tema de los sistemas fotovoltaicos, así como sugerir nuevos enlaces para compartir información relacionada: https://sistema-fotovoltaico-autonomo.zeef.com/es/marco.romero

Tips para mis amigos en Venezuela:

A.- El tipo de Panel Solar ideal es el fotovoltáico "Monocristalino" (celda hexagonal megra) que es el más eficiente. Los tipo "Policristalino" (azules), "Amorfos", "Arseniuro", "Teluro", "Diseleniuro" o "Tándem" no son tan eficientes (hasta la fecha).

B.- Lo más barato es construir uno mismo el panel solar, comprando solo las fotoceldas y armarlo!!! https://youtu.be/7urmHuOTp8k

C.- Para alimentar una nevera necesitas que tu inversor sea de 1.000 watios mínimo. Lo ideal es calcular primero la carga exacta (no todas consumen igual), para eso hay un aparatico llamado "Vatímetro" (Power meter).

D.- Para alimentar aparatos electrónicos, el tipo de inversor a utilizar debe ser "Puse Sine Wave" (Onda Sinusoidal Pura), ya que la electricidad debe ser uniforme. Los del tipo "Modified Sine Wave" (Onda Sinusoidal Modificada) son para cargas especiales y motores.

E.- todos los enlaces que he puesto con referencia a equipos en Amazon.com se consiguen más baratos en eBay.com comprando directamente al mayorista en China.

F.- Lo más difícil de conseguir puede ser la batería, ya que por su peso no es conveniente importar por courrier. En Mercadolibre.com.ve todavía se consiguen todos los componentes a buen precio.

G.- El tipo de baterías que se debe utilizar para sistemas fotovoltaicos son las tipo "descarga profunda" cuyo suministro eléctrico es uniforme. Las baterías para vehículos no son aptas por estar diseñadas para enviar la mayor carga eléctrica para el arranque (encender).

H.- Las baterías deben almacenarse sobre una tabla de madera preferiblemente (si le colocas ruedas mejor), ya que se descargan si las colocan directamente al suelo.

VRMark Preview

Continuing with the intention to make performance testing applied to Virtual Reality this time I used the "VRmark" software in its preview version; since the 3Dmark company (famous in the benchmarks world) currently still has this software in development.

This application allows viewing on HMD and Screen; recreates a typical museum scene with four exhibitions primarily (dioramas type), offering to the viewer a strong impression. These scenes are fully animated, and is a spectacular display of different kinds of lights, glare and reflections, particle effects, simulations of fire, wind, displacement textures and self illuminated materials.

Has been developed to measure the capacity to handle VR scenes, but currently only allows the visualization without any score. It can be downloaded as a complement to the latest Beta version of "3DMark" (3DMark Holiday Beta) which contains eight benchmarks test of highest quality.

SteamVR Performance Test

In order to check the ability of the hardware, I just did the test of "SteamVR Performance Test" application I found it really interesting because they use a scene with a robotic exploded view with very good animations, light effects and materials.

The application was created in order to be able to measure the capabilities of any computer for VR, in particular to validate the use of the HTC Vive (Valve business partner).

This application is completely free and can be downloaded from the indicated link, and does not require to have any HMD connected. Excellent application and more complete compared to the "Rift Compatibility Check" for the Oculus Rift.
