    pizeotg

    The piezo switch is something YOU provide, so it has to go through the body of the light (drill hole, provide o-ring seal etc). The piezotg board then has 2 wires that YOU solder to your piezo switch. The hallsw and halltg boards are a better solution if you are a) happy with magnetic switching...

    pizeotg

    Ha :) Haven't visited CPF for several weeks and was thinking to post up the piezotg board in the dive section and you beat me to it :) Anyhow, everyone loves pictures, so here's the picture of #1 piezotg board. Basically takes a piezo switch and turns it into a toggle action. The circuit...

    FLIR for Apple iPhone

    Cost is just under $1k delivered. The place I bought it has a discount for members of the eevblog so comes to about $900 delivered. Flir had a promo as well (might still be running?) and so I also received a borescope camera (LCD but not download capability) - which I already used to do some...

    FLIR for Apple iPhone

    Have fun with the melexis unit. Though it appears to be 16 x 4 pixels which will provide only a tiny view of stuff. Should be interesting to learn all the thermal issues first hand, i.e. stuff like keeping the microbolometer's temperature stable, doing calibrations as things warm up, the...

    FLIR for Apple iPhone

    The 'hack' for the 320x240 (for the E4) is trivial. It's hardly a hack, more a simple edit of ONE ascii file (with a text editor), generate a new CRC for the file, add that to the file and then use the Flir supplied tools to transfer the file via USB to the E4. There's also a nice menu system...

    FLIR for Apple iPhone

    http://www.eevblog.com/forum/testgear/flir-e4-thermal-imaging-camera-teardown/ is fantastic value for a 'real' FLIR today. Note the hack that gets you full resolution for sub $1k. I purchased an E4 a couple of months ago and performed the relatively simple firmware updates and have been using it...

    Aoyue hot tweezers?

    You don't need a tiny nozzle for hot air - I usually use a nozzle that is about 10mm in diameter and have no issues remove/replacing 0603 size components. Hot air tools are "the" tool to use for SMT. cheers, george.

    pop mech automotive LED upgrade

    Yeah, we get it for our kids - bathroom reading. It's definitely very light on anything useful and indeed is mostly ads or info-ads (even worse). It's one of those magazines you can find coupon/subscription for a couple of years for $5 or less (basically covers the cost of the mail and...

    7* XM-L U2 in FiveMega Elephant II host build: 7000 Led-lumen power BEAMSHOTS added!

    Re: -L U2 in FiveMega Elephant II host build: 7000 Led-lumen power (Very pic-heavy!) Great job! I'm pleased to see some nice attention to detail in assembling the light and also that you have decent soldering skills - trust me, I've seen many 'interesting attempts' and what some people call...

    Where to buy road flares?

    Seriously, 6+ year old thread and the first post the re-animator provides is a link to a website... Not at all suspicious? cheers, george.

    Driver turn on/off delay

    There's more to the turn on delay than circuitry powering up caps etc. OFTEN, a driver designer will intentionally utilise the Soft Start feature of the switcher IC to slow the ramp up time. This reduces what would otherwise be very large current spikes from the battery which can trip protection...

    What kind of magnetic sensor is used in rotary-control lights?

    Common tiny hall effect sensors are digital. All you need is a couple of them and a bunch of magnets spaced appropriately. Or you could use multiple sensors, all depends on the implementation. uC reads the hall devices to determine activity and direction (which sensor gets activated before the...

    Non-permanent LED mounting?

    I use a tacky thermal pad material (TGF150 by Ferrishield) from Mouser. It is sufficiently tacky to 'stick' to a hunk of aluminium and to 'stick' to a star. I can then hook leds in series/parallel as needed and also 'stick' the driver down. The material is tacky enough to hold things in place...
