About Posting a Comment

Comments are moderated before they will appear on the website, this is a manual process and may take some time. Please be patient.

Author Name is a required field.

Email Address is optional, but without one I won't be able to contact you back. It is never shown or linked on the website. You can always just email me if you'd rather not post a public comment. I generally reply in-line with a comment rather than email you back, unless I want to discuss something in private or off topic. Please check back to see when I reply.

Website URL is optional, if supplied the Author Name will be hyperlinked to this URL.

You may use wikitext in the body, preview may be handy here. Don't worry if you can't figure them out, just give me a hint what you want linked to what and I'll do it during moderation. Wikitext is not BBcode!

Spammers: Please don't bother wasting your time scripting up posts to this form. Everything is moderated, your post will never be seen on the web even transiently, there is no way to even view it by its internal ID, it will never be indexed. I will simply delete your post in the moderation interface. If I'm your target audience you're really on the wrong track; I'll never click on a URL in your garbage. The post content is not emailed to me (and I don't use a Win32 mail client anyway), I view the posts in plain text in the moderation interface so no clever tricks of any kind will make anything you type be interpreted by anything other than me, a human. Just give up and go elsewhere please!

That's quite a swag of ideas there for people! You should enter something yourself.

On the component curve tracer, I actually designed a 555 staircase generator for that purpose but thought the super-regen spectrum analyser was a better project to try first. The staircase generator has some other uses too - one completely obvious one is very retro/epic when combined with some window comparators and a few gates... I reasoned I could never build a debug something that ambitious in the available time, maybe next year. If someone did though, it would own the contest I suspect... If anyone wants my design sketch - ask after March. :)

Making the spider walk - yeah I had that idea too. Thermal actuator wire or solenoids/motors would do the trick. A cute idea with the family of spiders. I lack the SMD resistors to make a baby, but that's an awesome idea.

With some tiny solenoids or piezoelectric muscles driven by a 555 or 556, you should be able to automate those spiders so they crawl or jump around.

Maybe use the 555 & 556 DIP ICs for the daddy & mommy spiders and tiny SMT 555's & 1/10 watt resistors to make baby spiders.

555 ideas:

1) Audio swept frequency signal source with scope sync.

2) RF swept frequency signal source with scope sync.

3) Swept or stepped DC source for component analysis.

4) PWM for DC motor speed control.

5) PWM for electroplating Current control.

6) LF source for electro-deposition or electro-engraving.

7) Tunable LO for VLF direct-conversion receiver.

8) PWM based audio amplifier.

9) Boost, buck or inversion voltage converter

10) C or L meter.

11) Insect repeller.

12) Push button de-bouncer.

13) A:D converter (pulse width equates to DC voltage input).

14) Relay driver.

15) Electric cricket or bird call.

16) Guitar Tuner (tones generator).

17) LED Current pulser.
