Micro Transceivers

Some years ago my university employees had trashed away some brand new stuff, included these micro ethernet tranceivers. I'm unacquainted regarding this equipment... does someone have some information about those specific models, and especially some idea about how to utilize them in a diy project? How they works? Thanks!

Micro k'nex gun

So I get the general feeling that micro knex are the bane of a knexer's existence. But I was thinking the other day, why couldn't a gun be built with micro knex? As far as I can tell (I don't actually own any) they are the same as regular knex, only smaller. If one amassed enough micro knex, couldn't one theoretically build a fully functioning knex gun in the miniature? I just thought that would be kind of cool to have. Thoughts?

Micro High Voltage

I'm going to attempt to make a super micro tesla coil that is 100% contained (unless it runs off of like 12 volts dc, then I'll use a wallwart). Of course, one of the i biggest problem is the power supply. So this is what I'm asking, what's the best way of ramping up the voltage? A tiny toroid transformer? An inductor that gets pulsed? Voltage Multiplier? Something with static electricity? Some type of Inverter? Using Greinacher Cascades? A marx generator hybrid? Other stuff I havn't heard of?

electric micro kart

I want to build a micro kart with a range of 10 miles at an average speed of about 5mph, with a reverse function. Iv been looking at blogs and Instructables for micro karts and DIY electric longboards hoping to directly copy the basic components of another project however all the projects iv found are for high speed machines that often need a bump/kick start and i need something that will happily run at consistently low speeds without an assisted start. I don't have the electronics knowhow to work out what combination of motor, battery and ESC i need but from what iv read it sounds like i might need an outrunner (?) type motor which is apparently good for low speeds and high torque. Iv been looking at the Turnigy motors on the Hobbyking website as they were recommended by a few blogs, i tried posting this question on their forums a week ago but got zero response. Could you take a look at their motor selection and recommend the appropriate combination of parts? Thanks

Micro controller help

Hi everyone, I'm looking to get into the world of micro controllers but I have no clue how to decide on which one to start with. I have experience programming in VB on almost a daily basis and a class or two a few years ago in Java and C++. I don't anticipate programming being a hurdle. My main goal is to work with using my Android phone to automate certain parts of my life, such as automatically turning off the lights in the house and killing power to devices in "stand by" mode. I see a few books about the ease of combining arduino with android, but the reviews all state that the books assume proficiency in one or the other, meaning it's either targeted to an android programmer who wants to dabble with the arduino or someone who has micro controller knowledge who wants to incorporate the android. I have neither and need something basic for both. Something that starts from the very beginning. How the two connect. How they talk. Are their standard libraries and objects that they use? things like that. This is less a question/answer and more something I'd like to have some discussion on. Feel free to ask any questions if I missed anything. Thanks in advance.

I am trying to use a transistor to switch a 12v relay ? Answered

I am using a micro controller to switch a transistor which will then switch on a relay. I have heard that you need a resistor in between the output pin and the base of the transistor. Why is this and how do you calculate what size. Also the micro controller is running off a 12 battery which is regulated down to 5 volts for the controller. Can a transistor use a 5 volt source to active the base and then have 12 volts running through it activating the coil on the relay. I apologise for my poor electronics knowledge.

Need help with this MICRO camera ...?

Hello ... I would like to kindly ask anyone, that is good in electronics for help. I add 3 pictures of the SPY PEN and my questions are about the small camera(JH 70-B). I would like to make this camera to make VIDEO via a cable (not to write it on memory) ... but just by a (RCA) cable so I can use any recorder I would like. I have a few questions, that are bothering my mind and I can't help my self :( 1. would the camera be able to give video signal by it self or does it need some part of the PCB board ??? ... (I mean ... if I would give + and - to some of those pins ... and find one pin, that would give the video signal) 2. If I need the part of the PCB board ... could you show me, where would be the VIDEO signal ??? And where would be +/- ??? In my (totally amateur) opinion, I think, I will need a part of the PCB ... but I don't know, which of all these components are part of the "camera"to give video signal. Thanks for any advise ... zholy

Dremel Micro Repair/Reuse

Recently at the end of 2016, I acquired a Dremel Micro cordless rotary tool from a garage sale/yard sale for about $20. I used it maybe 3 - 4 times until it didn't want to hold a charge for long. Basically when I put it on the charger, the LEDs scroll top/down indicating it is charging but after a minute or two they stop their normal scrolling sequence and they all stay lit up, which isn't even mentioned of in the manual. The fuel gauge battery indicator shows up red meaning it's near its battery life. At this point, I'm considering either to salvage the motor or buy a new battery for the dremel (which are 2 Sanyo 14650 batteries that are soldered onto a circuit board inside). I'm just wondering is there something that I have failed to do that would make the dremel not hold a charge? Thanks in advance!

Feeding your MICRO TURBO

A Rampump with a small head , can move the water to a reservoir or tank to an elevation of up to 50 - 80 feet, almost no limit with high head. Working around the clock this device can move a lot of water. Volume moved is dependent on water flow and physical size of the pump. with 50 head ft. the micro turbo can output some serious power. 10-15-20 minutes each hour. while draining the reservoir

Controlling a servo with a Micro-controller?

So I decided to spend some time to make a "gimbal" in a very loose sense. Basically I was experimenting using a square wave oscillator to generate the correct PWM to have a servo rotate between 0 and 180 degrees when a tilt sensor is tripped. After some research multiple sites said having a 1ms pulse every 20ms would have it move to the 0 degree position. Great so I will make a oscillator pulses ~1ms on one side and 19ms on the other. However this does not seem to be working. I am curious if it is a fault in my math or if the tolerance on the parts I am using are just too wide to be any good. Here is a diagram of my set-up with the values a came up with. One spot that may be weak is that I just notice someone somewhere mentioned using 50Hz for the timing I just used that number when I calc my figures. Any feedback?  Also a side note is that I have been able to move the servo in one direction only and by accident ( in fact it's what inspired this project) when C1 & C2 were 2.2nF and the R1 & R2 were 10k potentiometers that I turned until something happened. Now that I am trying on purpose no results.

Mini/Micro Game System

Hi guys, I've been thinking. Really thinking. I recently found my Digispark (if you dont know what those are, google digistump, click on the first link and go to products, Digispark. They're really cool.) and decided to put it to use. I have always wanted to have/build something like a micro gaming system (sort of like the ben nanonote (if you don't what that is, google it, its really cool)) and decided that as a challenge, I could try implementing the Digispark as the Processor. I know that I wouldn't be able to run any games more advanced than pong, breakout or snake, but even those kinds of games would be enough to keep me interested while in boring situations. My basic thinking is this: There would a small lithium-ion rechargeable battery on the bottom to be a base (but still removable), the Digispark without any headers above the batteries, and a small LCD screen (1.8, 2 or 1.3 inch screen size) that would have either two pushbuttons (one on either side of the screen) or four pushbuttons configured in a D-pad style on the right side of the screen (how many buttons it would have depends on how many pins the Digispark would have open (if any), which also leads to my question, does anybody know any place to get video LCD screens (don't care if its color or not) that only take up 4 or less pins? I know that probably seems absurd, but if anybody knows any places to get them, please let me know. And just one last thing, is it possible to program games in the arduino IDE? Are there libraries for them? ANd if you can program games, just how advanced can you go?
