    Laser-powered Light Saber

    That is a really nice build!I was wondering if you printed a new cover that directed the air from the center plenum outward to each laser... and had a 10mm hole for each... printed slightly conically inside... if that would cause the air to exit at a very slightly higher pressure... and be more coherent. If it worked... the fog would stay together longer enhancing the effect more. Just a thought... all theory... but the only modification would be a new cover plate. Might be worth experimenting with?

    Footswitch Operated Sandblasting System

    Look closely an you will see TWO regulators... the pot is set about 35-40 PSI, and the footswitch is set about 60 PSI... about 20 PSI higher... just don't go over the rated pressure for the bladder... you know... don't run it at 100 PSI for example.

    Yes... the pressure settings are too close. the footswitch needs about 20psi more than the pressure pot. It needs to be able to really smash the pinch valve closed quickly... and likewise, it needs to be able to release quickly. When you let go of the footswitch, the air must be able to leave the bladder compartment to the atmosphere unencumbered.

  • DIY Home Automation with ESP8266 (Linknode R4) and Amazon Alexa

    I was VERY EXCITED to see this Instructable... After experimenting with an ESP8862-201 module, I was able to get a single LED to turn on or off... and I wanted to be able to pass more than just "ON/OFF" to the device... to be able to specify a few things. I just downloaded your code and I'm hopeful that I can get it to where it has a series of CASE routines... if so... then I can do even more complex things. (Trigger robot sequences, etc.)If I do manage to build off your code... I will DEFINITELY make sure to credit you with the core code. Up until now... this was as far as I got.Simple ON/OFF project video.Thanks,Jerry

    Footswitch Operated Sandblasting System

    If you look at the setup the way I have it... there is a main valve that supplies air to the entire system, then one for the pressure pot, and one for the footswitch/pinch valve.the reason is that you shut off the main air supply... and if you did nothing else... the system would bleed down and equalize... then all the air... and grit would shoot out the hose.The way i designed it... you go like this...1) System air2) Pinch Valve3) Pressure potThat way the pot isn't pressurized until the pinch valve is ready.Shutting down...1) Pressure pot... allow it to bleed down slightly bleed valve open if you have one. (Both pots are connected in my system... so I crack the second open and air bleeds out there.2) Pinch valve3) Main pressure valveHope that helps.

    That is awesome! When I had to design and build this... I thought to myself that someday... someone else is gonna want to do it... and that I may as well post the details and try to help them.So I'm really glad I was able to help!

    Epoxy Wire Bowl

    Very nicely done! I like the way the cables interact with the light and the transparent epoxy... great visual!One small suggestion... if you do that again... typical cables have a cord in them... grab it with a pair of pliers and pull... it will zip the insulation off in no time... then cut to length. (Save yourself some time.)

    Build a CNC router

    First the conversion... 2.2kW is just under 3HP. WATT to HP GOOGLE CONVERSION If you look at my Frankenlabs series, I'm using a 500W spindle. It depends on how aggressive you want to cut... the 2.2KW are very powerful. And the prices have really come down. Yours looks about the same as a 1.5Kw or 2 HP spindle. I saw some 1.5KW water cooled for about $220. including the drive electronics. You send out PWM and get full speed control from LinuxCNC or Mach. The 500W that I'm using cost me about $150 including all the electronics... and it's air cooled. (Much more quiet than a router.) Check out my video of it in action... Remember... if you need help usually (unless I'm traveling for work) I can set up a Skype or Google hangouts to assist you. Good Luck!

    Build a CNC router

    Very nice job... and the enclosure holds much of the mess as well. I will point out one thing you may be interested in however... at some point you may want to switch to a spindle instead of the router. I have a short video to show the difference... I'm showing a water cooled version... but the air cooled are just as quiet. They use the holding fixture as a heat sink. Is there really a big difference in sound? SPINDLE VS. ROUTERI think so.Jerry

  • How To Make A Bright LED Panel For 20$

    I am surprised you didn't mount the LED panel to the back of the frame to help protect the LEDs. This would also allow you to place a frosted sheet of acrylic to the front to help diffuse the light if needed, or to add color gels for different effects.Flicker: I saw the flicker at the 56 second point that was described below... it may have been caused by the panel, or by other light sources as it was not apparent in the video comparison. Installing a large capacitor across the output would help smooth the power out a bit more if needed.Overall... given the very low cost of this project... I think he did an outstanding job.

    PCB etching (prototyping)

    OMG! Someone else knows about Letraset... today's "kids" will never know... HOURS to lay out a board... trying not to get the little cracks which meant you had to flow solder over them... Did you know that you can STILL GET them?

    EXCELLENT INSTRUCTABLE !I've made circuit board for years... but have not done the solder mask or tinning... I didn't know you could get a solution to coat the copper like that... excellent tips!Thank you!Jerry

  • DIY: LED Workbench Light From LED Strips

    I have a suggestion... before attaching the legs to the project, cut two identical lengths of black heat-shrink tubing and slide over the lower parts of the lamp. Heat to shrink, then install the legs. This will give a clean black to silver transition to the project, and help to hide the wires leading into the lamp.An alternate idea... which would perhaps look better, would be to fabricate legs from a nice hardwood stained a dark color. The leg on the side of the electrical connections could be routed to conceal the wires and contain the power switch. It could be held on with small wood screws and would facilitate easy repairs if needed in the future.

  • Make a Seamless Captive Nut in a 3D Printed Part

    One reason would be the material used... some filament is flexible like rubber... it would never take a tap. You may still want to secure it tight, to make a seal or something. This way you could install nuts at regular intervals, and without the possibility of loosing them. Possibly in a hostile environment, to protect them from rusting for example. It also opened the door for other things, like embedding a circuit board, an LED, a switch, a magnet for sensing, etc. I could see this method being very useful.

    Getting Started with Atmel AVR and BASCOM

    It sounds like you have an incorrect serial port referenced... so it is attempting to send the commands, but not to the correct location. If you are using BASCOM, then try looking for information on the BASCOM forum.http://www.mcselec.com/index2.php?option=com_forum&Itemid=59

  • Self Watering Garden - Using recycled water from an air conditioner

    Yup... drip only... the PVC is not pressurized, with holes drilled in it at regular intervals... strings carry the water to the ground. I don't live there anymore... but it has been in continuous use since about 2001 or so. (I think that's when I built it... LONG time ago,)

  • Make your own development board with microcontroller

    You may want to look at the Tiny-26 processor which has 4K of memory. I have been using BASCOM for decades as my compiler of choice... I have an instructable on that as well. MY BASCOM INSTRUCTABLE (The demo / free version goes to 4K) If you are not limited to 4K of memory, try the Mega-328 chip which has 32K of memory. Have fun... it is very interesting to work with microprocessors!Jerry

    Mini Emoticon Keyboard

    Ok... I'm an electronic tech (CET), I've been doing computer in one form or another since 1978, and I'm a bit of an all-around geek. Never heard of a switch tester before today. Seriously. So I researched... and found out they were for testing the feel of the Cherry MX type switches... I saw a whole bunch of different colors and thought, "What's up with that?"So... I finally found out about the differences: CHERRY MX SWITCH TYPES.Now I got it... and I've learned something for when I go looking for switches in projects... so thanks for that! Overall... great instructable! I like the ability to hit one key and have it type some text. Could be useful for other things like frequently typed commands, logon names, or similar things.

  • When you have to say goodbye, How to properly bury a pet.

    Hypertufa is a great material to work with... you can be very creative in your design.

    Sandblasting works very nicely for rock and/or concrete. My wife has done sandblasting in different materials... and it comes out very nice. While the masking material is still in place, spray paint a contrasting color into the marks. When the masking is removed, it comes out very nice. Likely there are places that do sandblasting nearby and it should not be overly expensive.
