Re: EtherMega is back is stock

Hi John

I noticed Electus is out of stock, and Jaycar have very scant stock at the moment. Is there another batch of ethermega's on its way ? I'm after 3 for a job (I think - the part number I was given didn't make sense, it's either an Ethermega or a screw terminal shield)

USB driver 2.0 fails for XP

"for legacy reasons" I'm running something in XP in a VM. When I tried installing the latest USB driver v2.0, the install failed saying "a service installation section in this inf is invalid". After a few attempts, I found an older driver v1.1 on my machine, this worked fine ! Maybe worth linking to...

A respectable enclosure that caters for shields

For me, a project with breadboards and jumper wires hanging everywhere simply isn't an optino -I want my projects to work for more than 5 minutes. Yet there is a dearth of enclosures. Today I found this one from Hammond Mfg http://www.farnell.com/datasheets/1751687.pdf, which looks nice, but the dev...

Re: stackable I2C motor shields/brushed DC servo driver

thanks - I'll follow your progress for sure. I assumed I'd use relatively 'slow' encoders, nowhere near the MHz range the HCTL chip is capable of, so my default would be to use hardware interrupts to read quadrature encoders on GPIO pins. But please don't take my comments as criticism or let me slow...

Re: Epic Freetronic combined build PID for Brewing

I plan to have 2x 240V 10A (2400 watt) providing heat switched by contactor and SSR Wow, that's a lot of heating. Unless you know you need all that, I'd start way lower, or you may get problems with burn-on, and poor controllability due to having to run a very low duty cycle. From a pracitcal viewp...

Re: EtherTen running hot

thanks Jon

I agree the heat appears to be coming from the wiznet chip, but I've never noticed an ethermega glowing like my etherten seems to...

will have to take more notice next time.

normally means wrong board selected. I get it sporadically when flipping between (physical) boards and forget to change the board selection in the IDE

what regulator ? I was powering from USB, surely that just goes 5V -> 5V, bypassing the regulator.

Re: Powering with 12volt Car

sorry to revive an old post, but felt obliged to add my 2c worth. In short, its a bad idea. * the electrical environment is notoriously bad in cars, worse in older models. poor contacts in the alternator/regulator can result in spikes up to 40V * Lead-acid batteries are around 13.2V fully charged * ...
