    Cool project. I do hope you'll correct the amazon links in you list of components as they all point to the same item.

  • Recycling Styrofoam (EPS) Into Useable Castable Styrene Plastic at Home

    There are a number of people on youtube that have strapped an orbital sander to a bucket with bungee cords and use that as a parts washer, the same technique might work to accelerate the dissolving process.

    That would depend on the foaming agent used to expand the polystyrene, many years ago, certain hydrocarbons were used but those have been phased out because they were found to deplete the ozone layer, in recent years other non-toxic expanding agents have been used instead so if the styrofoam is less than 20 years old, it's probably relatively safe.

  • Easy ESP8266 (Arduino Core) Web Controls With EmbAJAX

    I'll be keeping an eye on that github page, the first item of the TODO list there, is exactly the sort of thing I'm looking for, i.e. a momentary push button rather than a toggle on/off button.

    Wow, that's a lot of grinding! You're a far more patient man than I and it shows, the end result is gorgeous.

  • Controlling a Raspberry Pi Via Windows Hotspot

    Good stuff! I'd like to do something rather similar except I want the Pi to create the hotspot then log on to that hotspot with my laptop or mobile device and control the Pi via vnc or ssh.

    Control AC dimmer Lamp using Arduino

    That sugar device is pretty cool. If I'm reading everything correctly, it takes accepts a generic PWM input and outputs phase angle controlled AC at mains voltage. Is that correct?

    Even though I use the u8glib library and will likely continue to, I love seeing bare bones stuff like this, Good job!

  • DIY Weather Station Using Arduino, DHT11 & BMP180 Sensors

    Just curious, why multiple sensors rather than an all in one sensor such at the BME280?

    DIY Logging Thermometer

    I couldn't agree more, and in addition to that, the way it has been presented, it could easily be used as a jumping off point for any number of different projects. Thanks for sharing!

  • How to Unscrew a Nut that's Stuck on a Bolt (without ruining threads)

    My "go to" thing for stuck nuts or bolts is a torch. You don't need an expensive oxy-acetylene torch either, any torch that is capable of using MAPP gas will do (propane's not hot enough), I'm partial to the one with a built-in piezo lighter. The method is heat the nut to red hot, shock cool with water, reheat and spin off the nut while hot. Works almost every time even with bolts that are very severely corroded.

    I'm in Canada and we can't get the real MAPP here anymore either but the MAP-Pro (99.5% propylene) that replaced it gets hot enough. I have a friend that's a mechanic and he hardly ever uses his oxy/fuel set up any more, he finds the hand held map-pro torch with ignitor more convenient.than the oxy/fuel torch with the large tanks and hoses.

    Cheap, One Chip Arduino

    I used to do stuff like this but now I don't bother as I can buy a pro mini for less than a 328P. I'm happy for the convenience however I'm a little sad as well, I think we risk losing something when things are too convenient.All that aside, excellent detail, great job.

    Make a Personal Weather Station

    Like a few of the other people that have commented, I too am wondering about your choice of components. A different esp module such as the esp-12 would have allowed you to eliminate the Arduino and similarly, a Bosch BME280 sensor has pressure, temperature and humidity sensor all in one very small package, that would have allowed you to eliminate the DHT11.

  • Liquid Level Capacitive Sensor

    Just curious, have you measured the actual capacitance range of your sensor? I just constructed concept capacitive level sensor using a piece of 3mm thick coroplast, aluminum foil tape and some waterproof sealing tape. I made it sort of as a proof of concept, it's about 18" long, the capacitance when the sensor is dry is 0.3 nF and when it's in 9" of water it's a little over 2.0 nF . I'm wondering how that compares to a sensor like yours. I haven't connected it to an arduino yet, that's my next step.This instructable motivated me to start working on this. Thanks.

    The torch you recommend is an excellent choice. I've got the same torch, for many years I used an inexpensive propane, they work well enough but the trigger start MAP torch is much nicer to use, I'm never going back.
