    High Speed Laser Hole Drilling

    @unclesyd Thanks for the info. That company looks like the UK division of Oxford laser for which we've spoken with. It sounds like they do great work but not at a price we can afford to product the product. @tyerdawg Thanks for the concern. Our prints have all the details on them including...

    High Speed Laser Hole Drilling

    We're trying to determine what laser technology is required for the high speed pierecing of thin metals. Our application calls for 0.004" hole in both 6061 and CRS of thicknesses varying from 0.015-0.025. From several RFQs and respective quotes, we've learned that many if not most laser...

    Heat resistant plastic part

    Thanks all. I've got some Vespel on order. I'm hoping that it will be a seamless replacement and we'll be back up and running. Engineering Incredible Solutions www.incredilution.com

    Heat resistant plastic part

    You're right, that looks very similar and would definitely work. Mcmaster says its over $70/inch ... wow. Guess this project isn't going to be cheap. Engineering Incredible Solutions www.incredilution.com

    Heat resistant plastic part

    Problem: So I recently purchased an FDM 2000 3D printer. It was very neat when it was working. I had to reload the material and noticed the head was leaking (from previous owner) creating a huge ball of plastic. I knew the problem would only get worse so I disassembled it. The picture shows...

    voltage regulator

    Can you tell us anymore about the output specs of the generator? I'm not sure if you're telling us the output of the generator or the output you'd like from the voltage regulator. Can you give us both? Engineering Incredible Solutions www.incredilution.com

    Need schematics for electronic thermostat

    There are a million different ways of doing what you're asking. You need to determine which is the best for your application. To get you started check out these: http://www.maxim-ic.com/appnotes.cfm/an_pk/3965 http://focus.ti.com/lit/an/slaa129b/slaa129b.pdf...

    Need 220V 50Hz Power Supply

    I need to do some testing with a power supply that simulates the power utilized in Germany. I need it to be as close to perfect as possible. I'm looking for a converter that is affordable. I've seen inverters but I'd prefer something that ran off of US 120V 60Hz line power. I found one that...

    Need help desiging a Simple and Cheap AC regulator

    VE1BLL & Skogsgurra I knew I posted on here for a reason. A combination of what LionelHutz and VE1BLL said would make for a mean little controller. With this I could even have say some kind of input (hall effect) to change the total power output for other future products or if the customer...

    Need help desiging a Simple and Cheap AC regulator

    Hi Gunnar, I am not aware of any PF requirements in the US. We have harmonic current requirements but I believe it is for applications consuming > 75W. Can you point me to some material I can read regarding EU/CE requirements for PF and harmonic current? LionelHutz, You have an excellent...

    Need help desiging a Simple and Cheap AC regulator

    I guess I should elaborate more. The solution must be under $15 so that eliminates every commercial 48V supply I've come across. I've discussed high volume pricing with a manufacturer of a nice 48V supply but they just cannot come close to my target. My quantities are 10k+ so it is affordable...

    Need help desiging a Simple and Cheap AC regulator

    Power is actually the most important. I am looking for a temperature rise from ambient not necessarily a certain temperature. The power level is approx 35W. The time constant is a few minutes as its rather large. My voltage is the worldwide range, I just neglected to mention it for reasons...

    Need help desiging a Simple and Cheap AC regulator

    Gentlemen, I am not a power guy and I'm struggling trying to find a solution to my problem. I need a circuit that will allow me to adjust its power to a fixed resistive load. The input MUST be capable of 100-240V AC and the output power must be consistent throughout the input range. My...

    Spark plug wire inductive pickup for RPM

    So recently I've seen several devices that have a pretty neat way of interfacing with most modern day combustion engines. Instead of complicating the installation of a device with having to find an RPM pickup to splice into(coil trigger, engine position sensor, etc) several manufacturers are...
