Raspberry Pi

The Raspberry Pi is a credit-card-sized single-board computer developed in the UK by the Raspberry Pi Foundation with the intention of promoting the teaching of basic computer science in schools. (Source: Wikipedia)

We also got hands on the much acclaimed Raspberry-Pi, thanks to OLE Inc in Cambridge, USA. We have tested to see if we could replace our traditional school server with Raspberry-Pi model B. However, Raspberry Pi couldn’t handle the the task when we loaded our digital library E-Pustakalaya on it. Though the page were browsable, the performance was very slow. We replaced Apache with Nginx and optimized Mysql, but still the CPU power was not powerful enough.

cost reduction by embracing latest technology
Upon more investigation, we found more expensive but highly powerful Raspberry-Pi alternatives like Odroid from hardkernel. It comes with 1.7 GHz quad core CPU and 2GB of RAM. We are hopeful that this can replace our single core 1.6 GHz atom processor school server. We can reduce the cost of our future deployment tremendously by substituting MSI server, inverter and battery (for power backup) with Odroid, battery pack and SD card.

    I’d love to hear how Odroid performs as a server. I’ve used RaspberryPi to run Pathagar (a OPDS book server). Its performance is OK, but the SD card can be a significant bottleneck to the write cycles. http://www.olpcsf.org/node/115

      I’m going to use eMMC instead of SD card on Odroid. 🙂 Also the price is pretty similar.

    Any Demo app to see the performance .. ?

    Did you buy the chargers (1000mA Micro USB) in Nepal? We are currently about to set up a classroom with 8 RasPi’s but did not yet find any suitable charger :-/ If you can give us a hint where to find these in Nepal, we would really appreciate this. Thanks in advance. Linda

      You can check around the Cellphone stores, yo are likely to find the suitable one for your need. I am currently using Raspberry Pi 3 Model B off a Samsung Note 5 charger 5V 2.0 A and its smooth.

    I am very interested in Raspberry Pi. Where can I find it in Kathmandu??

    Thanks in advance

    if you want to create a server out of Raspberry Pi then clustering will be a better idea i think. Now that Raspberry Pi 3 Model B is available it could do more.
