    Fix a Hole in Drywall

    Wow.Initially was going to skip as I am an old hand at home repair.I learned a new way to fix a moderate size hole in drywall. Did not think to use the careful removal of the drywall material leaving the paper for making a very study, smooth patch.Excellent Instructable, great pictures, great details for a real repair.Kudos(whatever a Kudo is)

    Self Spinning Gyroscope

    Everybody dies and that is beautiful.from "Don't let it Start", They Might be Giantshttps://www.youtube.com/watch?v=7gy2JJBoUbMTake comfort that "Nothing last forever".One day, all my sins will be ground down to chaotic dust, unrecoverable (of course that means your greatest joys will also be gone.)

    Homemade bike

    Wow, very impressive.Unfortunately, 3-wheel ATV(All Terrain Vehicle) were outlawed in the US in 1988; primarily due to stability issues when doing the AT part(All Terrain) of the Vehicle. Be careful, 3-wheel ATV have a tendency to tip/roll on hard left/right turns. This one looks way more stable with the front wheel forks extending farther front than common.And getting the Front-Wheel powered is a true engineering skill.It does look awesome, I want one.

    Stackable Shop Storage Boxes

    I think I will jigsaw cut two 4inch(10cm) ovals on the sides as hand-holds to make it easy to pick-up.Great Instructable, been looking for a good project for my small portable TableSaw (as I don't have a router to cut the top/bottom Z).Final part for me will be to put wheels/castors on the bottom. Don't forget to make one or two locking castors,

    Use Your Tablet As Raspberry Pi Screen

    Don't stop with the Raspberry Pi.You can use VNC on any Linux based or Windows based computer. Install "tightvncserver" on either, configure(make sure to give it a password) and start.Set the VNCserver to be either view-only or complete control.Once you get it running, you will install it on anything you want to remotely access.!Security Warning! VNC has little or NO security. do NOT VNC on an open network as 100% of your keystrokes can be captured and logged.If you need more security, try tunnelling VNC thru SSH, google instructions.I agree, NEVER open port 5900(VNC) to the wider network, that is just asking for trouble. Even SSH will be targeted with 100s of login attempts ever minute. Anything that is internet facing WILL be probed/attack and you will quickly find out ...

    use "ifconfig" to get the IP address (or addresses)."hostname -l" may return 127.0.0.1, the localhost IP address.ifconfig will list all active network interfaces.So, if you have a small USB-to-WiFi adapter, you will have two-2 real network interface: eth0=Wired Ethernet, wlan0=WiFi (and lo=loopback, the internal network)You could use the simple shell script with grep to get just the ip address(es):ifconfig | grep "inet addr:"

  • KeyPi - A cheap portable Raspberry Pi 3 "Laptop" under $80

    I was interested in which DC-to-DC Boost you are using but...the DC-to-DC Boost link actually goes to TFT LCD Display from Waveshare.Also, the Waveshare 3.5inch Resistive LCD Display is great price from GearBest.com. (Unfortunately, I bought mine for more at Amazon.com.).Using RaspberryPi3 with built-in/integrated WiFi. Otherwise, need the USB-to-WiFi solutions.Additionally, you can use a USB-to-Bluetooth Keyboard to allow detached keyboard and reduce wiring (Warning, issues operating Bluetooth and WiFi in close proximity, both are 2.4GHz and both will razzle each other's wireless link)The only thing I would add is a power on/off rocker switch.Next, turn this into a wrist worn PipBoy(Fallout reference).

  • Make your own development board with microcontroller

    Yes, need a resistor on the BC238 transistor (transistors are current amplifiers). Run risk of damage to transistor as you pour un-limited current into base(resistor is current limiter).Replace BC238 Transistor with an N-Channel MOSFET to direct drive from a Digital output. There are pin-compatible versions(gate=base), but I don't have time to search. TO-92 package so even if not found and exact pin-match, you can always install "cross-legged".Let us know what you do with this. (Add a remote control? re-architect to eliminate crystal?)

  • Webcam to security cam (movement detection + email alert)

    Yes,"motion" also works on Ubuntu, RedHat, any Linux OS. It is free, open source and relatively easy to setup. Works with any Camera that is recognized by OS (that shows up as /dev/video0).As a bonus, Linux offers much better management features on the captured images"motion" will also work with RaspberryPi but you will need to build for RaspberryPi ARM processor. Once done, you have a nearly mobile(power with USB power stick), WiFi possible, Motion Detect camera.I have loads of Webcams lying about my office and now I have a good remote, use for them (although, I will most likely AC power+Battery backup the RaspberryPi+Camera)Thanks for the idea.I'll post my solution with hardware, software and instructions once done.
