content: I know that. When I hit the back button now my mouse is right in the chat box so when I use the scroll wheel I'm scrolling the chat box. It's a small thing, obviously, as all I have to do is move my mouse, but it's the small things that make sites, appliances, or whatever either a pleasure or a pain to use.

content: I find that the middle mouse button (open link in new tab) does not work anywhere on the forum front page now, so I have to remember to use ctrl+left button instead.It appears to be a bug in Firefox 3.x that is triggered by the "contenteditable" property on the shoutbox input field:Code:<input id="NChat_input" onkeypress="if(event.keyCode == 13){ NChat_sender(); return false;}" style="width: 95%;" contenteditable="true">

Microchip MAPS rant - Page 1
Forum section: electronics / general

author: AkosL

timestamp: March 15, 2011, 08:18:49 pm
content: Hi!I just wanted to check out if Microchip has PGAs with differential input. They had a table-layout for parts display, and since the PGA category contains only a few parts, and you can see most of their relevant infos in a table. Should take 1 or 2 minutes to get the info, right?WRONG!Whatever i do, the "MAPS" Microchip ADVANCED Parts Selector" comes up. A few words about it:To process the request, and send a HTTP 302 response takes over 1 minute.I clicked in the PGA section, and the "main" MAPS page comes up, half dozen clicks to get to PGA parts again, not the section i am interested in.Unbelievably slow and unintuitive to use. Most clicks, or changes take 3-4 second to get a response. Learn real client side scripting, and get rid of updatepanels FFS.No option to just "list all parts and show the details".SideBySide comparison popup-> no link to the parts?-> send by email -> can't close the dialog. Also, entered dsa@dsa.com just to get rid of it, and a nice ASP YSOD comes back. Nice.Yes, I am angry, and frustrated. Why they had to replace a reasonably working solution with something totally useless.Do the have ANY QA? Did anyone tested that thing before it went live?

It's rather annoying to do a nice 5 minutes spiel and then screw up something near the end!I'll occasionally review material while I'm filming to make sure I didn't say anything stupid, but often I only find out something didn't work at the editing stage and I rarely go back and-shoot something (which is sometimes not possible anyway).

content: I have an idea for a new blog:I have been looking into replacing some PAR30 halogen recessed flood pattern lights with LED based solutions. Specifically, I have 6 of these lights in my living room and 10 in my office.While I certainly didn't expect a dimmable LED replacement solution to be the same cost as incandescent or halogen, I was shocked to find just how much they're asking for these lights.Under $3.00 US for a PAR30 short-neck, 75W halogen flood, while similar LED solutions are between $45 and $85!Honestly, I do not know how much goes into the design and manufacture of the LED based replacement. I was thinking a blog explaining the challenges, costs, possible solutions, and future of LED based incandescent replacements would be an interesting blog and learning experience.

A few concerns/peeves I'd like to see included: Is it better to have three independent supplies instead of a triple? Why shared displays are retarded (I want to see the voltage, current and current limit displayed at all times for all outputs; blue for voltage, red for current and yellow for limit setting). LCD is for low power applications like portable equipment running on batteries, not for a lab units plugged into the main.

content: MOV's are under investigation by UL and European lab's.I have seen a note to prevent the use of MOV's if not absolutely needed.Problem is that the grid is not as clean as it use to be with every other home owner supplying power back to the grid. This is usually done with a PWM sinus. This generates a lot of high frequency pulses that could trigger the MOV. If it is constantly triggered the MOV gets hot and eventually will set itself on fire.The same is happening with EMC X-capacitors.A few jobs ago I saw a few machines came back from the field with capacitor and MOV's that caught fire.The Capacitors were X2 rated 250V AC and tested with a DC voltage of 1250V for one minute before shipping. They came back with a hole burned it the side used in a domestic application.

Put more acquisition memory in it so it would be a 4 channel version of the DS1102E.How about a mod for the DS1000 series that turns the rear BNC connector to a trigger out signal? That way you can use the scope to trigger an external device like a logic analyzer for example. Much more useful than the mask feature.Scopeman

Created by Adam Meyer, bildr is a community for artists, designers, makers, builders, or anyone interested in the world of electronics and code. Unlike other sites, bildr is not about documenting user projects, but organizing and presenting information in a way that will help users build faster and better. bildr is about getting your ideas going by giving you everything you need to know up front without hours of scouring the internet.Short video explaining the concepthttp://bildr.org/about/Adam had the idea over 20 months ago but started working on the actual site January of this year. bildr is non profit and always will be. It came out of beta Oct. 17th and is now open to the public. Though still has a long way to go before it is done, or feature set. At the moment bildr needs more knowledgable people such as Dave Jones and this community make it a success. There are still lots of parts to be documented with brief explanations and workable code (MITlicense)Thank you for your time we hope to see you over on bildr.

Im hoping to use something a bit bigger for this project but don't really know where to start.Most reasonable sized displays for a micro-controller project seem way up in the 70$ price.. I'm really looking for something graphical but colour isn't an issue.

Regulation of car chargers. Is your car charger killing your expensive iPhone - Page 1
Forum section: electronics / general

author: haxby
author_rank: Contributor
timestamp: August 06, 2010, 01:46:00 am
content: There are many car chargers on the market that use a standard 5V USB plug. Some are rated at 500ma and others 1A.There is one available at Jaycar at the moment that claims a 1.2A output. I recently purchased 3 different USB car cigarette lighter adaptors, and I measured the ripple voltage at various loads. The results were quite surprising. None of them had a ripple voltage of less than 100mV at 500mA, and at full load the ripple voltage was nothing short of attrocious. They probably only work because the phones themselves have filter caps installed to combat this.These devices have become smaller and smaller, and the current batch sit flush with the cigarette lighter. So there is not much room for any filter caps or inductors. I wonder if Dave could use his universal dummy load that he has just built to do a few tests of common cigarette to USB adaptors.This would be a cheap tutorial as the parts would cost less than $20, and some quick CRO shots woud be very beneficial for many users of these devices.
