    Restore Solder Paste that's getting dry?

    not sure which forum this belongs in... but here it is: Has anyone ever successfully 'thinned' solder paste that's gotten a bit stiff? A while back I bought a supply of it from DX; but then became unable to use it... Now I'm beginning to claw my way back up to where I can do a bit of hobbying...

    Virtual Village - bad experience

    I'd like to hear from other people who've ordered from VV. Good, or bad? I recommend you watch out for them, they can really nail you for shipping multiple items! When I ordered several lenses, they charged me their regular shipping rate for each one! I did see that on the checkout page...

    my 6X blu-ray sled observs - 295mW !! (then death)

    First I must start with a disclaimer: my observations are likely to be crude and unscientfic compared to what others can do - I only have brief times to play with this stuff, often terminated  unexpectedly and abruptly; so am not very organized or methodical. That said... The day after...

    help with programmable logic chips?

    I've been trying to mess with programmable logic chips and such... have no problem defining the logic (havng been a programmer for ~30 yrs), and designing circuits is pretty easy. But I'm having a real problem getting the logic to the chip! I can't seem to find the right software to go between...

    extremely slow loading

    For the past week or so the site has been extremely sluggish - taking literally minutes to completely load some pages. Is it just me? No other sites are acting that way.

    buyers beware: BlueFusion fraud

    edited 6/10/2008 to change title. Still no package received in spite of promises by BlueFusion that my item is on its way; conclusion must be that I've been scammed. [hr]original post: has anyone actually received any item from BlueFusion? he's a month overdue on a deal with me - has promised...

    Protection from your Protection Cap

    just to update, emphasize, and reinforce a few other posts I've made: blown another diode, even though you're using a protection capacitor? ==> put a resistor in parallel with that cap! <== you can use a surface-mount, between the diode pins! With most drivers, 1K or so in parallel will...

    Free (almost) metal project boxes

    I posted this idea in the DIY power meter topic, but it might be useful to others too: People often ask where to get metal project boxes... and I found an excellent source for free! Having paid $27 or so each for DVD burners just to get the laser diodes, when another project came up I decided...

    Liberty Torch powered by a single 18650

    This is my new red burner. It powers an Optnext hl6545mg diode from a group buy at Photonlexicon using a single rechargeable lithium cell (18650 size) in a modified DX Romisen RC-M4 flashlight. To get current regulation with very low overhead I used a circuit posted by Phenol. The name "Liberty...

    Blu-ray in a DX greenie CR2 housing

    Nobody sent me any dead greenies from DX as I had asked, so this may become one-of-a-kind... This was a pretty easy mod. The DX red modules here fit almost perfectly into the DX green CR2-powered body once all the guts are removed. I don't like tail-switches, and wanted to use a push-button...

    dead DX CR2-powered greenies wanted

    I've found a use for the housings of CR2-powered green lasers from DX - specifically these products: 10093 - (Genuine New Wish 5mW Green Laser Pen (One CR2 Battery)) 7883 - (30mW Flashlight-Style Green Laser (CR2)) 7116 - (Professional Green Laser 10mW (CR2 Powered)) If anyone has any, in good...

    wanted: Sticky for Circuits of Common  Driver

    I hope I'm not asking for something already here, but haven't seen this anywhere - is there a thread of circuit schematics for common drivers? Like what's in flashlights ( eg Dorcy), drop-in boards (AMC7135), LM317, the simple 2-transistor, etc. It would be nice to have a moderated thread, with...

    Reed Switches for secret safety switch - DONE

    this is done - all spoken for. but feel free to PM me if you want some - if there's enough interest I'll make up an order for some of the really tiny switches, 1/4" long - better than what I got on eBay - but will cost 75c each + mailing expenses (unless I find another cheap source) [hr] Got...

    hidden safety/power level switch idea

    Got some tiny magnetic reed switches really cheap yesterday (25c), and did a little testing... found that a DX neodymium mini-magnet will activate them at about 1/2 inch distance through shrink tubing. So... my next laser will have a built-in hidden switch that will change it from a 5mw pointer...

    Burner diode report - sort of...

    Well, I finally broke down and ordered a 20x burner for the diode - a Sony NEC Optiarc 20X AD-7190A The diode was amazingly easy to get out - no pressing needed, just pried it out with an exacto blade! It's an open-can, so needed to be a little bit careful - but got it right into a housing...

    my latest Blu-Ray 'mod'

    This was a combo modification - I used parts from 2 very different units. I wanted to use 3.6V rechargeables, and wanted it to be thin like an AA type. The rechargeable 16400's are supposed to be AA size. So I ordered some of them and a Romisen RC-P3 flashlight from DX that seemed to be right...
