It's times like this that I find I can only laugh at the markup of products in stores. These exact speakers, not of similar type, but these exact ones, model and everything. I pay around $0.18c each for them, whilst RadioShack charge $4! I know people need to create a markup to generate profit, but this is like 2,200% markup! Personally I find charging between $1 and $1.50 reasonable, and maybe stretch as far as $2, but no more than that!

This is just like Maplin here in the UK... some 5mm RGB LEDs that I got for around £0.02 each, they're charging £1.20 for!

Things are always cheaper in large quantities. That is where the phrase "Cheaper by the dozen" comes from :-)

+Chris Holden I saw this and the only reason I thought of sharing was the yellow device I noticed on the third image! ;)
What is it? It's a Breadboard Holder and Parts storage box that is shaped like an 8-pin Integrated Circuit. Why did you make it? As a fun way for kids to build circuits or to package the kit for my book "Programming PICs in BASIC". What makes it special? It's unique and is a fun way to introduce electronics. Note: Includes plastic box and Breadboard. Other components shown are NOT INCLUDED!

Nice find. I just had another two delivered in the post - time to get programming again!

I've been finding the same issue for a number of months now. If I find something on eBay, I have to check other places first before placing my orders. Would you believe those little speakers I'm buying from Farnell are less than half the price than the best deal I can get from China in large bulk orders? My gym supplement powder is £3 cheaper from a regular online retailer AND is the bigger tub with free shipping than eBay.

eBay used to be the "go-to" place for getting stuff on the cheap, but now it's just another outlet which you need to do some research and comparisons on. Every time I need to order something now, I open up a spreadsheet with a list of the things I need, and then gather links and prices to each source and go with that.

With Maplin though, I dare you to try find rechargeable batteries of the same capacity for cheaper than they are in their store. Short answer is, you won't. Maplin might rip you off when buying small electronic components, but just because that's over priced with them, does not mean everything else is!
For years we've turned to eBay for cheap, low volume components. Quite often searching for something on Farnell or RS returns three or four of the same thing from a supplier on eBay (unless buying in suitably large volume). But over the last six-to-eight months, we've been receiving fewer and ...

I've just started my Kickstarter campaign! The kit will teach you regular soldering, as well as surface mount. It also comes with a booklet teaching you everything you need to know about basic circuits, sound waves, controlling RGB LEDs, data transfer over infrared LEDs as well basic understanding of programming in C! The kit is completely open source, and the programming headers are exposed so you can completely change the game into whatever you want it to be!
Affordable, fun & interactive kit that teaches you how to solder as well as writing code. Learn how Infrared, RGB LEDs and sound work!

Random device ID is familiar for me. I get that on some of my ATMega8 chips, and the reasoning is badly soldered chips (bad connections). Once I fixed the connections, they all began to work just fine. I also get the same problem when my USBTinyISP (or AVRDude) gets confused (I tried plugging in two so I could power two boards), and AVRDude picks up random Device IDs that change each time I ask it to check (even after unplugging the second programmer). I needed to unplug them both, close AVRDudess, plug in just one, open AVRDudess and try again and it was okay.

Unfortunately I find AVR chips extremely flaky! However I do like how easy it is to get up and running with them on AVR Studio (select the chip, compile code once, it gives you a makefile, never touch the IDE again and just use the makefile and notepad++ or sublimetext from that point onward).
Sometimes it's nice to spend a few hours of a wet weekend making stuff for the sake of making. Etching PCBs can be fun - after all, that's why so many people are drawn to electronics as a hobby, and making your own circuit boards, from start to finish can be quite rewarding.

The only question I have on this is if it allows you to handle vector images on Silk Screen or not? The one thing that Eagle is lacking is the ability to add custom images/vectors to the silk screen, and the only way to import than is to convert them to black and white mono BMP images, import them, pray they are the right scale, delete, tweak & re-import until the scale is right as it actually imports them as thousands/millions of individual pixels/blocks which cannot be grouped to move around and scale!
I have no problem paying for things, I do however have a problem paying for something that doesn't do the job half as well as it's free alternatives!
As ever, we're always planning one step ahead with our projects. So while we've only just got everything ready to hand-print a few prototype boards, we're already considering the possibilities of having boards manufactured (there are UK-based companies that can manufacture medium quantities of ...

ExpressPCB does an excellent job at churning out PCBs, for me! It out-performs all the free and paid-for alternatives for everything I need. And it's easy to use. And it's free. The easiest way to get custom artwork onto pcbs would be print to pdf (using CutePDF) edit in Inkscape, then run one of the pdf-to-gerber apps?

Learn to #solder big through-hole components and surface mount. How simple circuits work with NPN #transistors, how sound works, timer interrupts and even how to transfer data over #infra-red while also having fun!

Another fun project from one of the Makers (me) at the Build Brighton Hackspace in England. Any help I can get to promote this project would be really appreciated!

+Chris Holden you might find this interesting with the board games you making?

My latest project Space Buddies is on Kickstarter, and so far seems to be doing well! Share the link around and help me reach my goal!
