Last week Danielle was ordering some stuff off of Amazon, and I asked her to look up Ultrasonic Sensors, she did and they should be here latter this week. But this is not about them. Instead is is about a related item that we purchased at the same time. A 37 piece sensor starter kit, from Robotlinking Inc. (though my kit the parts say that, but says Elego on all the documentation )… Continue reading “37 Sensor Kit”
This week I started helping one of the local schools get ready for their upcoming FTC competition. Well…as of right now I have not done much other then gathering my ideas. It is a 4 person team, each with their own roles. They are running Java to control their robot, using Android phones.
Eagle Cad is my preferred PCB design software thus far. Though its expense has encourage me to try out KiCad. Back in Jun 2015 I started to use KiCad. Below are a few notes that I have taken. Let me know if you are interested in some videos on this software. These notes are current as of 16 Jun 2015. Continue reading “KiCad – PCB Design Software”
As you may know I started my journey in Electronics through Ham Radio in the mid 90’s. Then about 15 years ago I went through a trade school learning more about basic electronics. After I was working for some time, I earned a BS in Computer and Information Science. A lot of jobs/vocations prefer that a person continue their education, if it doesn’t help with promotion it can help with job security. Most of all it helps stay current in today’s/tomorrow’s technology and keep our skills up. Below are a few CERTs I have started or would like to have. Most of these CERTs and courses are either low cost or free.
I have been making my own PCBs (Printed Circuit Boards) for some time now. First, I had to create the schematic using software like EagleCad or KiCad. Most of my work has been done in EagleCad, though KiCad is free. Then from the schematic I go to creating the board layout. Dell-Ray got me stated in using this software, and thought me the basics. If there is any interest, I might be willing to make some youtube videos on EagleCad or anything else I am covering here. Well after I design the circuit and its board layout the next task is to get that design onto a board. Here I will talk a little on my journey through making circuit board. Starting off with chemical etching, then why I moved onto using a CNC router. Last, some of the pitfall to doing it your self.
Time Lapse photography has been an interest of mine for a very long time, but I have not had the proper gear. Some cameras, such as my Nikon Coolpix, have a time lapse feature built in, but it is limited on the intervals for taking the photos. The professionals use a Intervalometer, also called a timer remote controller. Naturally, I wanted to make my own remote controller!
Looking at projects I could do. Googled SWR + Arduino and this is what I found. This could help me along with some of my projects. One thing that would make it even better was if it could read Frequency. Yes, you should know the frequency from your radio, but having this function can lead to other projects.
Last year I built my first hydroponics garden. I was trying to do it all inside, and in doing so my lighting bill was eating away at my spending cash. This summer I have decided to move the garden outside where there is plenty of sun light. The only problem is I do not have power to run the pump. This is how I am getting around that issue.
As you might have already seen from my previous post, I made my first 6 Meter Receiving Converter with Bob, W5BOB. Well he gave me his 6 meter transmit converter and together we modified it to work with my TS-120s HF radio. Knowing that I was new to ham radio, Bob typed up some simple instructions on how to operate the transmitting converter and gave me the basic schematics of the system.
Find out how to build your own 6 Meter to 20 Meter Receiving Converter, and see the story behind me building my first converter. Please post any questions that you might have.
