Fusible resistors on series with non-fusible


May 28, 2016, 4:14 am

Some of the resistors in a circuit I'm designing would be a liability in some failure modes, so I intended to use fusible resistors. Unfortunately, the range of values available to me is somewhat ... Read more »

Rubbery conductive 'ink'


May 28, 2016, 12:30 am

Hi all, I'm working on a project, the sensitive part of which will live in a milled-from-solid enclosure- RF style. In order to contact the defensive walls with PCB traces (with copious via sti... Read more »

PEM nuts into lexan?


May 27, 2016, 9:51 pm

Anything like a PEM nut that I could fit *into* a sheet of lexan -- without worrying about torsional forces cracking the lexan or working the PEM nut out of place? Read more »

Clamshell sealing (maybe a little off topic?)


May 27, 2016, 8:50 pm

Anyone have experience (good or bad) trying to seal plastic clamshell packaging on a budget, and have it look semi-professional? Translation: My little garage experiment didn't work as well as I ha... Read more »

Reflow soldering for dummies

  [ 2 ]
May 27, 2016, 4:20 pm

In all my years as an electronics hobbyist, I've never bothered to experiment with SMD and reflow soldering. I have a project now that is a very simple board and may even try some of those DIY techn... Read more »

ATTiny ADC and TWI


May 27, 2016, 2:31 pm

Looking at the ATTiny datasheet...why oh why do they put one of the ADC channels on the SCL pin? So it seems if you want to use all four ADC channels, it's not possible to connect the uC to an i2... Read more »

OT: Blocking websites


May 27, 2016, 2:11 pm

Firefox 46.0.1 I have an annoying website, kt9267.com specifically, an advertising site that is launched as a separate window when I access The Washington Examiner. It does nothing because NoScri... Read more »

Again with a power supply input protection


May 27, 2016, 12:16 pm

A circuit will have 24V @ 1.5A (max) input from a wall wart. I'd like to design in reverse polarity and maybe over voltage input protection. (There are lots of threads about this.) I don't li... Read more »

STmicro acceleration/magnetic sensor LSM303DLH == LIS331DLH + HMC5834?


Just had a look at the LSM303DLH datasheet and had a déjà vu ;-) It looks like ST has simply put a LIS331DLH and a HMC5843 into one package. (The HMC lacks the built-in voltage regulator) All data ... Read more »
