Tor/VPN Router [How To Auto-Connect VPN After Tor Connected at Boot]

Dear Instructables Family,Hope you are well and healthy. My name is Enes and i am living in Istanbul. As you know in my country everything is being enforced by brute force to people. Tor, Wikipedia, Imgur, Pastebin, NordVPN, ProtonVPN, Privateinternetacces, PureVPN, etc. many website and service is blocked. There is no "privacy" in my country. For this reason i am looking for a "full privacy solution" for me and who is living same fate since years. I read many article and project but i couldn't believe they are "full privacy solution". Today i encountered with a "Raspberry Pi VPN server project" and i liked it. I have one (RPI 3B) and want to make a full privacy solution with VPN and Tor (with obfs4 bridges it is working but they are blocking everyday our bridges and we need to find another bridges every day). I created a Tor router with RPI and it is working good (little bit slow but i don't have any choice). But i want to add more security and privacy to this router. For example i have a VPN membership but i can not use it because it is heavily blocked. I want to do something but i couldn't find how can i make. Let me explain.My Onion AP is working for now good and when i connect as a client from a computer, i can access https://check.torproject.org website and everything is OK.My VPN membership supports TCP and UDP OpenVPN. It has TCP and UDP .ovpn files with a lots of country. I installed Open VPN on Raspberry and configured it for auto-connect at boot. It is working, when i reboot Raspberry, it connects automatically. But i have a problem.This VPN firm is heavily blocked and i can't use it. I tried ikev2, L2TP, Obfuscated Servers, Onion Servers, Double Servers and Standalone Servers of this VPN but there is no luck. Then i tried something. I connected Tor Router from computer and tried to connect this VPN firm. I could connect, it worked. Because i connected first Tor router and then VPN.My current schema is this:RPI ---> Internet comes from eth0 ---> Tor ----> Share Tor Connection by wlan0To Do:RPI ---> Internet comes from eth0 ---> First Connection Tor (I don't want to share Tor connection immediately because i need to connect VPN with Tor, if i share immediately by iptables, there is no Tor connection and i can't connect VPN) ---> Then connect VPN ---> Share Tor/VPN internet by wlan0I searched on forums, blogs and websites lots of. OpenVPN is using tun0 interface. I have three (3) questions. I am stucked here.1) How can RPI connect VPN with Tor without forward Tor connection? (Connect VPN with Tor and then share Tor/VPN. 2) When i achieved these steps how can i test Tor/VPN connection from a computer (client)? I mean how can i seperate them? 3) Should i add these commands to iptables-ipv4.nat script?-A POSTROUTING -o tun0 -j MASQUERADE -A FORWARD -i tun0 -o wlan0 -m state --state RELATED,ESTABLISHED -j ACCEPT -A FORWARD -i wlan0 -o tun0 -j ACCEPTIf i achieve this i will be so happy and restful.Could you please help me about these issues?P.S: Sorry for my bad English.Thanks in advance.Best Regards, Enes

LVDS board with raspberry pi

Hi there, I recenlty purchased a M.NT68676.2A LVDS board and connected up to my raspberry pi. All of this is working fine however the setup at the moment looks like frankensteins attempt at a pc, so i was wondering what is the best way to go about building a box to contain my setup, bearing in mind i have no CAd or the like expereince and no access to a 3d printer (no small ask i know) I want the box to be able to support a 15" laptop screen and have the ports accessible on the outside. Look forward to some ideas. Thanks

Reading Electric Meter with Raspberry Pi

We have a meter outside of a building which displays how much energy the building produces (Solar Power) and pumps back onto the grid, how much the building uses from the grid, and the difference. Every day we record these numbers, and enter them into an excel spreadsheet, so we know exactly what the efficiency is of said building. The issue is, is that this building is empty for most of the week, and driving to and from the building costs time and money. So, the idea is that we have a Raspberry Pi connected to a camera photograph these numbers, and send them to us via email. How would you have the Pi take pictures? Specifically, what camera would you use? The screen is a ~3cm x 12cm LCD display (Similar to an alarm clock display, no colors) The clearance inside the box is about 10-15cm from the screen. The box itself is transparent, but we'd like to keep the camera inside the box, as the plastic isn't 100% clear (weathering), and it would also look more professional.  The box is waterproof, but not moisture proof, so it would need to be outdoor rated. Or is there some type of device we can put over the screen, and then have it copy what the screen displays? The screen/meter itself cannot be tampered with, as it belongs to the electric company.  This camera/device needs to be able to be sourced in Europe, and would be nice if it wasn't too expensive. Semi off topic: Would it be possible for the Pi to somehow analyse the images, and convert the numbers in the pictures to text?  Taking it one step further, would it be possible to have it automatically enter these numbers into a spreadsheet? This display cycles through about 10 different "screens", of which only 3 are needed. Could the camera be used as a motion detector, and when the numbers change, it takes a picture? This would be repeated 10 times, so that every screen would be captured, and then the needed images would then be sorted out, manually or automatically. If any more information is needed, just ask. Thanks!

I want to make a wooden music box, where do I start?

I'm thinking about making a wooden speaker box that plays music from one of my favourite games. The box would have an embossed panel with this logo on the front: https://si0.twimg.com/profile_images/1878799410/AnimalCrossingLeaf.png on the top would be the speaker face, buttons to play and stop (2 seperate or a toggle) and a button to switch between playlists. On the back, would be an on/off switch and power cable if it requires one, although I'd prefer it having a battery. So, what wiring/technology would I need? Could I break open an mp3 player and cannibalise it, or would I be better off with a Raspberry Pi, and with the Pi, would the software be hard to make? (have the buttons perform their actions). Lastly, what tools would I need to do this? Thanks.

help building a mobile juke box

Hi it would be cool to get some help and ideas with my project to build a mobile juke box, the main part of this idea is that it needs to be low powered as a lot of the time there will be no electric supply, we like to have partys in fields and on the beach  so im thinking it will be better to have a 12 volt system that can run of leisure battery's ive got two 120amp leisure battery's in my t4 van  and when thats not going to be available to use i have a spare 120 amp leisure battery that i could put in the bottom of the jukebox but i have no idea at the moment of how long that would run the system. im thinking the system would comprise of car speakers one 12 inch sub one 10 inch sub two or four 6 by 9 speakers two or for 6 inch speakers two tweeters an amp or two to run everything raspberry pi b+ about a 10 to 15 inch screen some funky led lighting i would love to have some juke box software for the retroness and it would make this easy for some of the less techy not sure if that possible on the raspberry pi? one of the ideas ive had is, as well as having some basic controls (i dont want a full keyboard)  having some 'genre panic buttons'  basically when everyones had enough of putting tunes on (too drunk!) you can hit a genre panic button and the juke box will play on its own, so far the only way i can think to do this is to have a harddrive with several partitions on with music pre installed into the own genres that the jukebox will shuffle and play when one of the buttons is hit, but i have no idea how to get the partition to play by hitting a button though. any input or ideas to help me get my head around this would be fantastic :) thanks

Know of a cheap 24v li-ion to run a boom box?

Hello, I've been building boom boxes of various sizes using 24v amplifiers. I can never find medium sized 12v class d amplifiers, so I am forced to used 24v. My favorite amplifier is the tk2050. The inexpensive li-ion cctv batteries I use for my 12v amplifiers can't be used in series because the internal circuitry seems to cut out.  Can anyone help? Extra points for simple, cheap, light. Something around 7 Amp/hrs would be great. Maybe under $30. Oh, and how would you charge it? Thanks!!! Tor

PS1 LCD Screen into a Raspberry Pi Monitor

So i finally purchased a Model B Raspberry Pi. I'm quite enthralled by the stuff ill be able to do with it, but i figured i would start by making it a case. That idea somehow resulted in using a cigar box i had lying around to turn the whole thing into a laptop-esque build thing. The inside dimensions being 8.5" x 5.4" x 1.5", i looked around and i have a PlayStation 1 with an LCD screen. The console and screen are fine but the hinge is broken. And given the size of the screen, i thought it would be really nifty to disconnect the screen and use it as a monitor. The only problem is im not sure if i could make it HDMI or RCA compatible. Any Tech people think this could be done?

D.I.Y. Automotive Black Box, DVR, OBDII

Friends, I am a noob that is considering building a Black Box for my car, I suspect that I am not the first so please if you know of discussions on developing an awesome Black Box please direct me to it. The Black Boxes being offered are Gold Dusted empty, expensive crapware. I want added protection from bad drivers, bad insurance companies and bad cops so I want six or more 1K or better cameras and DVR with the ability to store on any size SD card and/or SSD. I also want telemetry from many sources like GPS, speed, throttle and brake pedal positions, steering degrees, OBDII and more. Two problems I suspect will be power drain when the car is parked and chip cooling. I'd like to Stink Tank this idea with interested peeps (WOW! I always wanted to use Peeps, yeah, I know Late) I look forward to hearing from you Sincerely

Went away for the weekend- these were waiting when I came back

A mere three months after ordering, I went away for the weekend, and my Raspberry Pis (raspberries pi?) were both waiting for me when I got back today.  One of them is already earmarked to become a media centre/web server/NAS all-purpose box.  I've got a couple of ideas for the other one, but I could always use more inspiration. What should I do with my second slice of Pi?  Patch* for the best idea (even if I don't actually make it).  No, I won't accept "send it to you" as a suggestion :) I'm already torn between a MAME arcade cab and some kind of carputer. * Judge's decision is final, one per customer, no cash equivalent, consult your physician if symptoms persist

Using Arduino + RFID to Email when something is removed from a box?

Hey everyone, I'm looking at completing  a home project using an Arduino (or perhaps a Raspberry Pi if its easier) and any help as to how to approach this or where to look would be really appreciated! Essentially I want a box filled with a number of items with RFID tags and I want the system to send an email telling me if an item has been removed (and preferably which). I'm pretty new to this, but I have a feeling I have seen similar projects around. Can this be done and if so can anybody help me? EDIT: I understand this may not be possible with RFID, but if so is there a different way of wirelessly checking (say once a day) if all items are present or not? Thanks!

Perfect battery?, deep cycle, SLA, help!?

Hello, I am one of a group of people that has designed a mobile ice cream cart.  https://www.instructables.com/answers/Got-any-cool-ideas-for-our-Arduino-run-LED-dance-f/ We are currently using 6 of those 7.2 sla batteries. They are set up as a 24v system. But its not good. They are hard to charge. And have begun to swell. We want two smallish deep cycle batteries, set on two battery chargers. Does anyone know a good place to purchase such batteries? Say, 25 or 30 A/hr. Are there batteries for trolling motors? How much should we expect to pay? There are also larger SLA batteries, but I just don't think they are meant to be drains so deeply. (we play this thing for 12 hrs at a time) Thanks in advance! Tor

Remote Lockbox

I would like to build a small lockbox to which I could remotely provide access.  For example, I leave the box at a property.  At a later date, an employee is in the area and we would like him to access the property without having to make a trip back to the home office to pickup the keys.  We provide him a one-time access code and he retrieves the key. I recently discovered how much fun Raspberry Pi DIY projects are and this seems like an ideal candidate for my next challenge but I have to confess I am still a total neophyte to all this with no real notion as to the best way to move forward.  I would welcome any suggestions or ideas.  I also realize my definition of the problem might be more vague than is ideal but given my lack of confidence vis-a-vis which details are relevant, I thought it would be more productive for me to answer questions rather than post a giant wall of useless information - which is my long-winded way of saying, please do not hesitate to ask me any questions if they'll help get me pointed in the right direction.

Challenge: Find an alternative use for all those IDE and floppy cables just laying around leftover from the dawn of PCs?

As everyone knows, since SATA came out, IDE and SCSI (termed as scuzzy) quickly became out-dated, now all these cables are just laying everywhere.  As and example, back at my dad's office, there are hundreds of floppy, ide, and scsi cables just everywhere, and i think it's hundreds of each. I'ma get a box and start compiling dem all. a picture of standard IDE cables, incase some of you don't know. http://upload.wikimedia.org/wikipedia/co... Above picture has a 2x20 pin array scsi internal cable usually has a 2x25, atleast the one i have and floppy if modified correctly has a straight through 2x17 array Now the challenge is, to find a great way to reuse these cables, it doesn't have to be an electronic related thing, if you don't want it to be. Now i've always thought, maybe a great cable management solution, something like two cards with some hdmi an rca inputs that connect together with this cable to clean up a home entertainment setup, that is one idea. or a wire harness thingy, to connect power, video/audio signals, etc. non-electric ideas would be like, maybe weave them together somehow to make a chair or something, maybe take off the connectors split each cable and weave them like a speaker grill, or just split them to use the individual wires for like, speaker leads, or just leads if you're a prototyper, like if you mess will arduino or raspberri pi There are lots more things you can do, but those are just some ideas... can you think of more?

Hobby CNC router/engraver idea

I recently had to fix a friends (chinese) mini router.Long story short short: I realised that those things are only good for a small Dremel but not a real router.After looking up what is available in the tinker areas it seemed the only way out is the expensive way of using servo drives.Not really easy to handle either if you want some Arduino or Raspberry do the computing parts...So what would actually be required to make a cheap but still usable tabletop router that can handle 10mm playwood or work with (at least) Aluminium?In most if not all cases the tool will limit the movement speeds quite drastically.If neither makes any sense to force the rotating tool through the material, nor to make several high speed passes to get the results.Even when engraving stone or aluminium (dry) you can only do it so fast.The hobby market is full of Arduino or Raspberry based router projects but most, if not all use standard Nema motors for the positioning.As a lot came from the 3D printing area I guess it just made sense.And if you want to run servo drives or similar you won't control them with some cheap Arduino.Nema motors however suffer from the problem of limited torque at higher speeds.And using normal gearboxes only goes so far as the higher the reduction, the lower the resulting max speed will be.Means in the real world a Nema motor would struggle with any gearbox to get a reasonable speed to work with high loads.I think the way out could be to use external encoders for the positioning.Like on the early ink jet printers the slotted band attached to the printhead did.Or if you are old enough you still remember the mechanical mouse that stopped working once the code wheels were full of dust.The Idea came to me when servicing a geared motor for a 8-way valve.Just a cheap Mabuchi RS555 style motor and a planetary gear box.Together they produce a whopping 800nM of torque and literally no backlash at all on the output side.High resolution encoder wheels with sensor are available quite cheap as well.I did some very basic math on the accuracy side of things based on a table size of 1.2x1.2m.Using a chain drive we are looking at less than 1/2 mm using standard chains and below 1/10 of a mm using tight, precision chains.Going lead screw and heavy duty, high torque the accuracy is about the same as on a good 3D printer but the speed will be quite slow - I guesstimated around 3-4mm/s.A heavy duty belt drive system seems to be perfect as we can adjust the drive pulley size to match the gear ratio and speed requirements.Chains work fine as well here but usually mean a higher overall cost.The benefits are really high torque with more than reasonable speed is possible.The mechanics and electronics can be kept very simple.No high speed processor required, a simple 8-bit Arduino Mega will do fine.No expensive motor controllers, just a simple DC motor driver with PWM control.Extreme holding torque when an axis is not moving thanks to the gearbox.Code sensor can be driven by the belt or chain to get direct distance measurements.Downsides of the approach....The initial costs will be higher than standard Nema motor based solutions.To my knowledge there is no Open Source project for this kind of approach available (yet).With the heavy duty mechanics it won't be very portable, best to have it stationary mounted somewhere in the workshop.Quick reversing of the direction will require suitable DC motor drivers that can not only reverse the polarity but also provide the option for a break resistor to allow a fast stop of the motor without backfeeding generated electricity.Getting 3 dimensions would require a motorised table which can be a challenge if you need to support a loaf of weight and stay steady while a tool causes a lot of pushing in all sorts of directions.Probably a sissor lift system in all four corners would work best here.Happy tinkering! ;)And if the idea is already out and in use just forget about it LOL
