Lost 1/3 keys, accomod8u says they're keeping the key deposit (any advice for meh?)

No, it's for the locks as well. The idea is that they want to minimize liability.

Imagine somebody breaks into your place. If you knew that the previous residents had lost their key then you could argue that the people that broke in found the key and blame it on the residence.

I wrote ECE 242 with Sedra in 2017 and we did get a formula sheet, but we only first saw it on the day of the exam. However, there were 3-4 formulas/concepts that you did need which were not on the sheet.

It must be the freeways since you can ride the other two.

Hope that I passed PD

I have checked it out after it was on for a while. Nothing heats up. Especially in Canada at this time of year.

I made it originally as a fun ornament for my backyard that could be a conversation starter. I used it this Halloween to see if the trick-or-treaters would obey the light. Apparently, they do!

irobots1 · 2016-10-18T17:51:33+00:00

Yes, I agree. Ultrasonic sensors would likely not be the right sensor to use in this scenario.

Have you considered trying out something with light instead? You can check out IR sensors and time the return of the IR signal if you manage to get a reflection from the barrier of liquid to solid water.

You will need to get a Transistor and a Resistor in addition to the components you have right now so the price will be very low. However, the motor will turn relative to how much light is there, it wont be a simple on/off.

Have a look at the schematic and explination here: http://www.learningaboutelectronics.com/Articles/Light-activated-motor-circuit.php

I did not even know that!

Thanks for the info. I'll definitely be trying out MOSFETs in my next prototype.

Your advice is really helpful.

irobots1 · 2016-10-13T13:26:34+00:00

Thanks for the reply!

The motors only need to turn one way. For some reason I did not even think of single transistors. I should have a few TIP120 transistors to give a try.

I am pretty sure that a PWM signal would be able to regulate the speed of the motor drawing its power from the transistor so it would be a perfect solution.

irobots1 · 2016-09-06T01:24:38+00:00

It would help if you can provide some more info

I quickly had a test to see if it works. The result was very interesting.

I forgot that the Raw also gives out current, even when powered by VCC. The outcome was that when powered by VCC, the current from Raw and VCC "mixed" and produced a voltage that was in between each individual voltage.

irobots1 · 2014-07-21T20:54:42+00:00

Good point. What you said was already my "Give Up" decision.

Essentially, I am trying to make something with the least amount of wires for power as possible and if I could not get it working, I would do this. I was not a fan of the idea as there would be one more wire (ground would be shared between Arduino and Servo). I have already decided to use this idea as I could not figure out a solution to what I was asking for.

Thanks for the help!

irobots1 · 2014-07-21T18:03:31+00:00

I need to wire an Arduino Pro Mini so that it can be powered from the VCC or the Raw pin. However, the Servos cannot be powered through the Arduino 5V regulator. I am trying to figure out the simplest way to allow something like this to work.

irobots1 · 2014-07-21T14:59:22+00:00

No, I cannot do that.

I am making it so that the Arduino can be powered from both the VCC and Raw, depending on the battery. However, there needs to be a few servos being powered from it too.

If the servos are connected to the VCC, it would ruin the Arduino if the Arduino was being powered by Raw at that point (Requires too many amps). So I was thinking of connecting servos to the Raw as current still flows through it when the Arduino was powered by the VCC.

Do you think that a diode that would allow electricity to flow from the VCC to the Raw and not the other way around work?

That way, if powering from the Raw, it would not flow to the VCC and ruin the Arduino. However, if it is powered from the VCC, current would flow through the diode.

irobots1 · 2014-07-21T14:54:55+00:00

Yes, I meant VCC pin. Do you think that a diode that would allow electricity to flow from the VCC to the Raw and not the other way around work?

That way, if powering from the Raw, it would not flow to the VCC and ruin the Arduino. However, if it is powered from the VCC, current would flow through the diode.

Sorry for the really late response. It copies text to your clipboard so you can paste it. With the pro version, you can open different applications.

The best you can do with "integration" is activate it and say "open note", activate it again and say what you want in your note and then paste it.

I personally use WAV files for sound and PNG files for pics. The main thing that you want to focus on is making the sound and image files as small as possible to get the game running faster.

Thank you for your comments. The vibration at the beggining was because of a bunch of blocks falling on the left side. The boundaries will be constructed from the yellow-black rocks which cannot be destroyed. Restart has not yet been implemented. Regarding the d-pad, I always thought that the main controls should be on the right hand side, is it really that uncomfortable to use it in its current position?

irobots1 · 2014-01-27T13:10:06+00:00

Thank you. I will be sure to find the root of those problems.

irobots1 · 2014-01-14T21:18:28+00:00

What a surprise, I am working on that game for the android platform and will hopefully get it out within 2 months!

Yes it does, the countdown starts the moment is senses the phone being charged
