Mini lcd's

I'm trying to find a mini lcd to use to display information. Sorta like the G15 has but in color. I was looking for lcds on ebay but could only find mini tv's that were expensive or computer monitors that go down to 13 inch. Does anybody know were I can pickup a small lcd around 4-5 inches maybe.

mini flashlight?

I am trying to make a mini flashlight, and it wont work.  any ideas, I have a 3mm high brightness led light, 2 3volt coin batteries and the connection wire.  Can any one explain specifically what i need, or have to do?  I'm just not getting it to work and also when the bright led lights up it only light up with an amber yellow glow for seconds before going out, upon which I have to give it a second for that to happen again...as if it needs to charge first.  What am I doing wrong? Thanks Matt

Mini-generator? Answered

I was sitting here today wondering how could an electric car with a gas generator possibly be useful, then it hit me.  I could add a gas powered generator to an RC car to give it the ability to fill up and run again without the need to charge a battery.  The idea was brilliant so I went out looking for a platform to use.  I decided on a traxxas E-Maxx.  It has a lot of space to build on, and it is a pretty awesome truck.  I decided I would leave the batteries in the equation and they would be sustained by the generator.  Now, what on EARTH DO I USE FOR A GENERATOR that doesn't cost as much as the motor itself.

Shop-a-Mini Contest

As Lira would say, I haz skillz. I do not, though, have any serious photo-editing skillz. So, it should be easy to impress me and earn a patch in my new contest; apply your skillz in Photoshop, Gimp or even Paint to join a Mini with anything else. Caitlinsdad's hybrid of my Mini and Thunderbird 2 (below) was the inspiration for this contest, so he has already won a patch. You can join the Mini with anything you like - animal, mineral, vegetable, even celebrity. You must use a Classic Mini (any model), not the BMW version. To win a patch, your image must impress, both with creativity and the level of skill exhibited. The judge's decision is final and potentially rather arbitrary. Ready... steady... shop! EDIT: This contest ends June 30th, midnight GMT

sub mini fridge

I just got some soldering paste and I need to keep it cool. The temperature has to be above freezing, but still cool. Currently I'm keeping it in my fridge, but I don't want to keep it there once I break the seal (for safety reasons). I can't do that one mod using the 12 volt camper cooler, I don't have a camper cooler. I can't afford a mini-fridge. Just seeing if anyone here has any ideas. If nobody has any then I'm going to buy this USB micro fridge wwhich will keep it cool for $15.

Really Mini Shocker?

Hi all, I am looking to build a really miniature, low-output shocker device and I've come a bit stuck. The instructables that I have see here all seem to dispense shocks of about 400v and I think they are too painful for what I have in mind, though I don't really know (if you know better then please tell me, you may make my life easier :) ). I'm looking for the device to be able to deliver no more than a distinct nip, and be about the size of a Cr2032 cell. I also would like a miniaturised power source like that. Can anyone tell me if this is possible and point me in the right direction as to parts and where to get them (I'd like to salvage as many parts as possible because I'm on a tight budget). Thanks in advance to all who reply.

mini fridge upgrade

Hello everyone, I found a Thermoelectric mini fridge at the dump a couple weeks ago and so far I have been disappointed with how cold it gets so I figured I would replace the peltier chip with a higher wattage one, the original ran on only 12v with 60watts but the new one uses 16v and 192 watts, so unfortunately when I switched the chips the fridge makes a clicking noise presumably from drawing to much current. the questions I have are, how can I build or cheaply obtain a variable (it would be nice to control power) 16v 12amp power supply or modify the existing board to output more power, would it pose a problem to run the fridge with no load attached to the previous 12v supply, and is it necessary to replace the fans with higher power ones? any other advise would be much appreciated, thanks in advance :)

Mini DVD won't finalize

I've got a DVD camcorder (Samsung SC-DC173U), and am trying to finalize the disc so I can edit the video on it. Problem is, whenever I do what the instructions tell me in order to finalize it, a problem occurs. The "disc Finalize" option is unavailable. The manual says that the cause of this is most likely because the camcorder is low on power, but it is fully charged. Any suggestions? Need I take pictures or do anything else to help?

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?

Mini Bike Chain Adjustment Trouble? Answered

I recently bought a bunch of pocket bikes all in good shape but all had some sort of problem.  I took the best parts off of them and made one extremely nice bike.  The one problem I am having with it is that the chain likes to come off.  There is a bolt connected to the back axle that tights and loosens and slcks or tensions the chain.  How do I find the "butter zone" where it isn't too loose to come off, and it is too tight to come off?  The two sprockets are lined up really well, but they are a little off.  Would it be possible that that was the problem?  When I say a little I mean like so small its less then 2-3 mm from drive sprocket to driven sprocket.

Automatic Irrigation using d1 mini

Hi Everyone, I reviewed different automatic irrigation system projects here in instructables and other sites as well and i decided to gather parts to do a simple small project myself. One thing that comes hard is the programming part as I don't know any programming language. I'm looking for some help with code merging, explanation and some general guidance. Could you please let me know, point me to right direction and tell me what you think and if requirements are actually achievable? What I would like to achieve: Intention of this project is to have manual and auto irrigation system which will: 1. Measure soil moisture and dependently on the value activate the usb pump which will water the plant (preferably analog output that will show the measurements in %) 2. Manual activating the pump via hardware button and via mobile phone with internet connection 3. Distance sensor which should measure how much water is left in the tank 4. Email notification with info when to water the plants and soil sensor data regardless of the automatic process that has already started 5. Email notification with info about the water in the tank when it’s near empty 6. Dashboard preferably inside the network (not using third party like blynk or others) with access from the internet (I have QNAP that I think can be used). 7. If possible – have amazon echo (Alexa) read the sensor data to tell me the values and comment if the plant should or shouldn’t be watered or the tank should be refiled or not as well as ability to ask Alexa to start or stop the irrigation Hardware: D1 mini: https://wiki.wemos.cc/products:d1:d1_mini Wemos V2 Relay shield: http://hobbycomponents.com/shields/865-wemos-v2-relay-shield My relay is slightly modified: 2 small wires soldered to the vcc and ground so that when it receives the signal on d1 pin it opens and current flows to female usb connector supposedly activating the usb water pump. All this can be stacked together even with soldered wires YL-69 sensor: http://www.oddwires.com/yl-69-soil-hygrometer-humidity-soil-moisture-detection-sensor/ Ultrasonic Distance Sensor (HC-SR04): https://thepihut.com/products/ultrasonic-distance-sensor-hcsr04 USB mini water pump: www.goo.gl/yUABDd Button x4 if needed: Board x4 if needed: sample codes used in other projects: https://randomnerdtutorials.com/guide-for-soil-moisture-sensor-yl-69-or-hl-69-with-the-arduino/ https://create.arduino.cc/projecthub/nekhbet/using-the-yl-39-yl-69-soil-humidity-sensor-with-arduino-968268 https://community.blynk.cc/t/irrigation-relay-with-timer-esp8266-wip/700 Alexa enabled homemade cat feeder example: https://www.hackster.io/darian-johnson/alexa-powered-automated-cat-feeder-9416d4 Thank you very much in advance for your help and support.
