While playing with the raspberry pi camera I found it hard to know if the camera was working or trying to tweak settings. I was using raspivid -f to preview the video. This was limited with being open for 5 seconds ( can be adjusted using the -t flag and passing it seconds in milliseconds ). The solution was to open a streaming video from the raspberry pi and view it on my host ( mac ).
A while ago I picked up a Davinci XYZ 1.0A 3D printer. I mostly bought this for three reasons:
- Ease of use as I was just getting into 3d printing and wanted something that would be a good step to start printing what I wanted. This is done w/ filament cartridges that know what type of material it is and configures the printer accordingly.
- 7.8″ cubed print bed, this was the larger printer volume on the market for the price.
After a few mediocre prints, I found out what some of the complaints were about. First is the EPROM chip in the filament cartridges. This seems like a bonus at first, but after you realize the cost per kg of the filament, you realize the price is obnoxious. You are forced into using their proprietary filament which is limited and expensive. There are ways around this like an EPROM resetter using an arduino.
Connecting to Raspberry pi 2, 3 and zero to a RFID sensor, This summarizes my experiences using the tutorial found on Sunfounder.
Imagine building a raspberry pi project at home that is dependent on wifi. Everything is working perfectly until you move that project somewhere outside your home network. You have to go find a monitor and keyboard to set it up on the new wifi. This process is difficult, time consuming, and stressful. I have had the pleasure to endure this multiple times throughout my projects. Especially when there is pressure to have it done for a public event. I was curious if there was a way to get the networks to be plug and play, where there would not be an issue when moving it from one place to another. Doing a bit of research I have found that you can setup multiple wireless networks on the raspberry pi.
Have you been slogging your winters and summers in your IoT lab making the next wonderful application? Or are you a blue-eyed enthusiast excited by the wonders of Internet of Things?
Networking is an art and conferences are the best place to practice it. You come across people who have been there and done that. Throw your ideas to peers and to big organizations that might be interested in investing in your dream. Let us have a quick look at the top IoT conference that will happen this year in 2016.
The Internet of Things is still a new tech kid on the block. People are innovating and achieving the impossible. It can be tough to quickly make sales, also something you create might not have customers. This could lead to a problem. You might waste a lot of time and as a result, depletion of funds can happen. Worst case scenario would be if customers do not like the product. There is a way of tackling both ends of this problem, crowdfunding. Crowdfunding has enabled innovators to follow their heart and seek funding from people. The customers get to use a prototype of the product and the innovator gets the return. Here are some of the best crowdfunded projects in the world of Internet of things (IoT):
