    Macro Lens Design

    I'm designing a device that has a small scale. I put a small magnifying lens (10mm diameter) over the top of the pointer to magnify the area. Currently it sits about 1.5mm above the text/scale. However with this lens it really needs to sit about 9mm over the top of the text to get the ideal...

    Spring Retaining Ball Joint

    Chicopee, true this definitely an option considering how inexpensive they are.

    Spring Retaining Ball Joint

    Thank you Greg. I haven't seen any with the nylon insert. I've only seen them like this with retaining spring ring: Metalfixer, thanks for the link! It's funny in the image they show the retaining ring but the 3D files don't have it. I appreciate the help!

    Spring Retaining Ball Joint

    Ok, maybe not. These cads don't have the retaining spring. so I'm still open to suggestions or 3D files. Thanks!

    Spring Retaining Ball Joint

    I need to create a 10mm metal ball joint like the one pictured and I'm wondering if anyone has any 3D files of something similar I could look at? Thank you!

    Need Help Choose LED Drivers

    Hi Guys, thank you for all the feedback. I should clarify that I'm looking just for the main driver controller chip and not the complete driver with mosfets, etc. My problem is that I don't know exactly what specs to look for. Coincidentally, Keith I've been dealing with Linear and they've...

    Need Help Choose LED Drivers

    Hi, I'm designing a couple of different portable LED lighting systems (Li-Ion powered 18650 batteries) and I am searching for a manufacturer for the LED drivers. Below I have listed the specs of the different parts of the system. I need some ideas on which LED drivers would be best suited for...

    Syncing 2 LED Strobes Via RF

    The Nordic chip I'm thinking of in particular is the nRF51422 https://www.nordicsemi.com/eng/Products/ANT/nRF51422 Thanks, Don

    Syncing 2 LED Strobes Via RF

    Thanks guys for the responses. I'm hoping to not have to add another chip if possible to keep the costs down with production. Liteyear, it sounds like your idea would work with 2 light systems but I'm wanting it to work with multiple systems. So whenever a new system came within range it would...

    Syncing 2 LED Strobes Via RF

    I'm still working on this project to get the BT devices to sync. I got an email from the engineer that is working on it and I wanted to get your take on it as to what the best solution might be. Please see his email below. Thanks, Don...

    Choosing The Right Battery Management IC for Li-Ion 18650

    LiteYear, thank you for your reply. The MAX8677 has a maximum output of only 1.5-2A. This would be pretty slow to charge a battery pack at almost 10,000mah. Do you have any suggestions on higher current rate chips? Thank you.

    Choosing The Right Battery Management IC for Li-Ion 18650

    I'm trying to find the right solution for charging a product I'm having designed. Here are the details: The unit consists of 3 18650 Li-Ion batteries. Depending on the unit the batteries will range from 1400mah for the entry level units to 3300mah each for the higher end units. I want to be...

    Syncing 2 LED Strobes Via RF

    Thanks everyone for your responses. itsmoked, couldn't I use the bt chip as the radio transmitter and receiver? Since I'm going to have the bt chip there already I'm hoping I don't have to add another rf transceiver to the design. VE1BLL, I like the idea and I think the strobe would be...

    Syncing 2 LED Strobes Via RF

    Hey, thank you, Keith. What you said makes a lot of sense. It seems easy enough to subtract the time delay if necessary. I appreciate your insight. Don

    Syncing 2 LED Strobes Via RF

    I hired an electronics engineer to design a portable LED lighting system that has bluetooth for controlling the LEDs (color change, strobe, brightness, etc.). One of the objectives is to have the ability for each LED lighting system to sync to one another. So for example if one system is...
