Ya, its been a while… What can I say, life is busy! Anyways, here is a neat project I created using an Arduino to make a Capture the Flag Game Controller for playing Airsoft on the weekends! You can use it for Paintball too! 😉
Here is the assembled tread and motor mount. Using a 12V 2A power supply I tested each unit and found that they work nicely. The motors are 30 rpm, so 1 rotation of the wheel every 2 seconds resulting in a nice slow robot that should be easy for me to control with the Raspberry Pi.
The final assemlby is below.
Right side up.
Next I will be building mounts for the DC motor controllers and the raspberry Pi.
A friend of mine is really into 3D printing, it looked like so much fun that I bought a ‘Wanhao Duplicator i3 Plus’ for $649 from the same place he got his, Spool3d.ca. It has been a great experience so far. I have been printing almost non-stop for the last month! This printer is very well built and I can definitely recommend it to anyone wanting to get started.
I have been using tinkercad.com for all my designs, here are links to a few of the models I have built. I am slowly building up a tank type robot for my Raspberry Pi. Fun stuff!
I have not posted much on my website due to working on several big commercial (windoz) projects using wxWidgets 3 / OpenGL / SQLite / MariaDB. I used to be a big fan of Qt, however the licensing was way to expensive for me to use it for any project that I decided to take commercial, so I gave it up and dove into wxWidgets. I am happy to say that I have found it to be most useful as a general purpose GUI building tool, and superior in performance and simplicity compared to Qt. I am completely loving wxWidgets and I plan on posting a pile of wxWidgets instructions and examples in the future to help support the community of wx users.
I recently built a sci-fi themed elevon prop-in-slot single sheet Airplane. My goal was to use only one sheet for an airplane that could fly with some of my smaller quadcopter motors, it weighs under 190grams (without battery). It uses a 5050-3 bladed propeller.
It flies great with either a 3cell 850mah or a 3cell 450mah battery even though the 850 is almost twice the mass of the 450. With the 450 it is so light that if you cut the throttle and pull the elevons back 50% the aircraft floats to the ground as light as a ball of tissue. Despite it’s aggressive appearance it is extremely forgiving to fly, and is suitable as a trainer.
I was playing without a gampad trying to fly my RC simulator and noticed how horrible it was, so I rewrote the keyboard controls.
The new controls do not require a numberpad, and are as follows:
[x] [w] for 100% elevator up and down.
[a] [d] for 100% aileron left and right.
[q] [e] for 20% throttle increments.
This is much easier to operate than the old method. So for people who want to try it out without a gamepad this is your best option. Try it out here.
This is the second product that EtekCity sent me for free for my honest review as part of their EtekCitizen program.
I requested this multimeter from them because I am constantly looking for my voltmeter, and needed an extra one to leave with my RC gear. This one retails for $16.98 on amazon.ca.
I have used this quite a bit in the last 2 days. I have too many large batteries around (for my Dalek, and a wooden go kart I built ), so I decided to give them all a check as well as test some continuity on some of the circuits I have built for my Dalek. I also did some resistive measurements on some bits of RC stuff as well. So far I am happy with this multimeter, it seems to work as expected. Is has a fast settle time (unlike my old tester) and the backlight makes reading the display very easy.
It feels very solid, and runs on a 9V battery. The only problem I have with it is that there is no battery cover, instead you need to take the unit apart (2 screws) to change the battery. Also it does not auto power down, so try not to forget to turn it off.
Conclusion: I am pretty happy with it, it will have a permanent spot on my RC workbench.
So I signed up for EtekCitizen free products in exchange for honest reviews to give it a try (ie. They gave me this ‘Roverbeat Bravo’ headset for free so take my review as a paid advertisement). I recently bought a food scale from them for weighing my RC planes and components and was thrilled with the quality of the scale, so I signed up hoping to get more great quality stuff as I was looking for a gaming headset for the kids. When I received the shipment it was well packaged.
It has very decent sound quality compared to my other much more expensive headset (AKG, K99 Perception), and worked perfectly with my Windows 10 pc and google hangouts, but it definitely feels a bit cheap, the ear padding is super soft and thin and I worry that it will wear out very quickly, only time will tell.
I am used to much higher quality audio gear, but this headset retails for $17.99 on amazon.ca so of course I am not going to find it up to par with my usual gear. However for a $17.99 price I would say it is actually a good value for money, I have given it to my kids and they have been using it for their gaming and loving it.
In conclusion: Not high end (duh, look at the price), but good value and so far it has been great for kids gaming. Happy kids = happy dad.
My 4 year old Ram 1500 mirror puddle lights failed recently, so I went to the dealer and was shocked when they wanted $74 per side plus $45 labor. I was really upset because I expected the LED’s to last the life of the vehicle, and the price was unreasonable. Since bright white LED’s cost almost nothing, I ordered a pack of 20 pre-wired 12V ready white LED’s from Amazon for $5 including shipping. After drilling 3 holes in each old light holder and soldering the wires up (Thick terminal is negative) I now have working lights that are brighter than the originals. It took me half an hour total, which is how long their mechanics supposedly would take to pop them out and back in. I posted this just to encourage anyone who can run a drill and a soldering iron to do this instead of letting the dealers take your money for such a minor job.
I also got a pack of 20 Amber LED’s for the signal lights as 2 have burned out on one side. I will fix that tomorrow!
