    DIY Magnetic Connectors

    Should mention that soldering to Ni is a pain, but if you do it right (ie low temperature indium solder) it works fine. The trick is to set the temperature of iron at the lower Curie (ie reversible) temperature for NIB magnets and use lots of flux.

    Magnetic Connectors for Batteries

    Great idea!Its a shame some enterprising manufacturer can't make smart 18650s with NFC reading ability (so any smart phone can check a bare cell) and these magnetic connectors built in. Also it might cut the number of ecig/model/etc related accidents as people switch to the new safer connectors.I would avoid soldering though and use spot welding, with 3D printed shroud that permits venting and mechanically shields the wires at both ends, and contains the NFC chip, cell protection etc.Once made a pack of LiFePO4 (cheap and nasty) and it might have worked for years if the soldering process hadn't weakened all those cells.

  • Running Mini PCI-e 3G Card With USB - Mini PCI-e to USB - Easiest Way

    Same idea re. RTL8191SE, as I have dozens of them.Alas the newer cards have no Ubuntu support but old dinosaurs like this are still 802.11n so more than adequate for p!r@t£b0xen etc. Or for that matter solar relay stations for those times you need Internet in the garden.

  • How to fix bad Chinese Arduino clones

    Also relevant. I have had "fake" units with defective 12 MHz crystals, the fix is to replace the part with a genuine unit. Also bad regulators, defective "FakeCaps" (tm), micros which only emulate the responses expected for "Hello World", etc. FFS.

  • DIY Infrared transmitter for iPhone, iPod

    Hi, just a heads up but some IR LEDs are more sensitive than others. I found that the VCSEL 900nm ones from optical mice don't like being overloaded and turn into expensive 0.01mW LEDs at much over 900uA input.If you are unsure its best to simply use the time honored techinque of putting an inline resistor and reverse polarity protection diode to prevent it from being damaged.It would probably also work well with DVB-T sticks that have lost their remotes, without which the stick won't turn on so Windows can install the driver.

  • Quantum Dot LEDs: Making custom color LEDs

    Hi, also another good experiment is to get some EL phosphor (I used old expired powder on Ebay) as this is a lot safer but will not be as spectacularly bright. Ask Gwent, they sometimes have some and so does Dr. Jarek and other suppliers. Look for anything that says "EL phosphor" or "microcircuit materials".. :-) The newer white material can be processed to get just red or green emitters out of it with some careful hackery!

    Replace your sony ereader screen

    I have to do this because my screen has severe ghosting and is basically unusable (old age maybe)- the new screen looks fine in comparison.Pretty sure that the newer panels are actually superior quality as the image is noticeably sharper and more defined. Hot wire cutter is also feasible with <44 gauge SS wire if you want to salvage the old screen and also less messy.

  • Amazon Kindle e-ink Screen Transplant from a Sony Reader

    The easy way to avoid troublesome filing of metal and excess thickness is to buy just the EPD glass which can be had for about £15 apiece. The old metal can be separated from the broken glass using hot 44 gauge wire (couple of 9V batteries + some tension) and the new screen simply glued in place with double sided tape.

    Re. ghosting, the fix for that is to use a panel with a similar -1.xx voltage to the old one. Its actually easy to do if you have a number of spare panels for another project, +/- 0.02 works then simply adjust the trimpot for best picture with least ghosting.
