The E3D V5 and V6 are great hot ends! http://e3d-online.com/E3D-v6 One thing to be aware of when switching from a V5 to the V6 is that because of the much more pared down nozzle profile, the force needed for extrusion is lower, this also makes the liquid plastic inside the melt zone much more likely…
Place all through hole parts on PCB. Wet underside with kester 951, 959T or similar liquid flux (not sure which is best yet) Place over PCB preheater set to ~220C for ~125C board temp. – 100C is probably a better temperature for this. – may be better to preheat board then quickly flux then dip.…
Reference for the idea What do you think? I still need to test this on a breadboard… I know you could use a schottky or normal diode on the 5V USB side as I am going to regulate it down to 3.3V anyway so the voltage drop is inconsequential. I know it looks like the…
I apologize for shakiness of the video – next time we will use a third person as cameraman! And yes, the mouse still worked when we put it back together 🙂
There are three sizes for the first video as I was testing how the different resolutions looked 😉

This is an absolutely great feature! wish id known about it earlier https://code.google.com/p/tinkerit/wiki/SecretVoltmeter
These battery backed SRAM and clock modules have a shelf life of 10 years, mine are at 17 years and still working as luck would have it! but if the SRAM fails you loose all installed options. http://www.mcamafia.de/mcapage0/dsrework.htm http://www.walshcomptech.com/ps2/dallasrework.html http://www.ko4bb.com/manuals/index.php?dir=Tektronix/Tektronix_-_TDS784_TDS794_Digital_Phosphore_Oscilloscope
Possibly the smallest 12 pin micro-controller currently available? Highlights: 1.5 x 1.4 x .5 mm 🙂 2KB 12Mhz 10 IO pins .4mm pin pitch Possible to route 8 of the IO using .127mm (5mil) traces and clearance You loose one internal pad due to trace width, and another external pad because one of the internal…
First things first, I had to know how this device was constructed. Conclusion: Much better than the cheap $15 knockoff I tried first. It uses an actual TI wireless charging IC http://www.ti.com/product/bq500211 My advice to those considering purchasing a wireless charging pad: get one from a reputable manufacturer like Samsung, LG, HTC etc.. The no…
Just an idea and a few parts for now..

One phenomenon not immediately apparent when selecting the proper ceramic decoupling capacitor for your design is the fact that the effective capacitance of these devices is drastically reduced under DC bias voltage conditions – such as when used as a power supply filter. This paper from Nic Components explains the phenomenon quite well: http://www.niccomp.com/help/VoltageCoefficientofCapacitors-032012-R1.pdf

First some links if you aren’t already familiar with Ubiquiti’s mFi platform – it is more than just a web enabled power switch – think vast automation capabilities when paired with their other devices and software. They also make some of the best wifi and networking devices for home and small business. I have a…
