   dear website maker,

   I have a question: I have a science fair box, but I don’t have the manual. Can you scan your manual and send it to me, please?

   Greetings from Nienke

   Unfortunately, I don’t have a scanner large enough. The pages of the manual are an irregular size and very large. I only have a normal letter-size scanner.

   I would also love to get a copy of the manual for my old set that my son is nearly old enough to enjoy but unfortunately my manuel is long since lost.

   Maybe if we paid you a few dollars each, we could buy you a new scanner ??

   Here’s what I think I can do: I’ll take a picture of each page with a camera and post them. Maybe I can then combine them into a single PDF. Let me work on it and I’ll post some results on this page soon (maybe just a couple of pages to start), so bookmark this page and check back in a couple of days.

   I too need the manual and am looking forward to you posting the manual.

6. rcgrabbag January 11, 2009 11:43 am

   It’s a big job, so I work on it when I can. Have you checked ebay for the manual? You’d probably have to buy the whole kit, but they are cheap.

   Where can I obtain replacement springs for these kits? The folks at Radiation Shack could not locate any replacement parts.

   I have the Science Fair 200 in One electronic project lab with the wires, unit and book if you are interested.

   Fantastic! When I was a kid I loved those electronics sets… I had a 10-in-1, a huge 150-in-1, and a 25-in-one focussing on solar power. Still at home somewhere….

    Jason, I also have a 10 in One, but have lost the manual. Any chance of getting a copy sent to me PLEASE!!!! I’ve been scouting the net for the last 18 months trying to find a manual or someone else with the 10 in One kit.
    My email is gcfisho at bigpond.com ( replace the at with @) …. hoping you can help me out.
    Cheers

    I have the Science Fair 160 in kit and manual
    I also have a Gakken 15 in 1 kit and manual. Is this like the 10 in 1 above?

    Also 2x Science Fair Junior Electronic Project Lab Kits
    1 is 28-153 Related to computer/logic circuits with manual
    the other is 28-151 and related to radio circuits.
    I am in desperate need of a manual for this.
    Thanks
    Andrew

    I WANT TO SEE A PROJECT TO MAKE NOT A KIT BECAUSE I HAVE A KIT

13. rcgrabbag July 12, 2009 9:25 pm

    Download the manual using the link above. And don’t use ALL CAPS. It makes it seem as though you are YELLING.

14. Yves July 15, 2009 7:40 pm

    Desperate researching manual for 28-277 50-in-one Radio-Shack Science Fair…

    I’m ready to pay for it!

15. Mike November 29, 2009 9:07 pm

    How is the manual comming along ? are you still working on it ?

16. rcgrabbag November 30, 2009 5:04 pm

    No, I haven’t done anything with it. But, it’s always helpful to get a poke every now and then to remind me that there’s still a need. I’ll whittle away at it, but it’s a time-consuming process because I have to take photos of the pages (don’t have a scanner large enough for its oversized pages).

17. JC May 26, 2010 11:11 am

    Do you have the schematic/pdf for a cat meow? I don’t recall what kit it was in 50/100/200 in One. Ty.

18. DH July 30, 2010 8:47 am

    Hi there

    I have a Gakken “world of discovery” computer logic lab. That is all that it says on the box – I inherited it from my older brother. Any chance that someone knows where I could find the manual for it?
    Thanks.

19. oz November 14, 2010 8:02 am

    I, too, had one of these kits in the late ’60s/early ’70s… and was still hacking away with it when I was in my 20s

    The link to the .pdf of the manual seems to be broken and only a zero-size file is available. Would you please re-upload the .pdf?

    Thanks

20. rcgrabbag November 15, 2010 10:27 am

    Hi, thanks for the notice about the broken link. It’s now fixed. Keep in mind this download is not the complete manual, just a few select projects.

21. oz November 20, 2010 10:57 pm

    Thx for the ‘link repair’ Interesting, though, as I don’t remember the ‘characters’ in my version… nor the wiring ‘table’ (it was just a list of ’18-50′, ’22-23′… and you had to decide yourself about which colour to use – only some lengths of wire were long enough to make the connection)… but no doubt, there were some things lost/gained in the translation from the USA to Australia

    Grand memories…

22. Randy Garrison March 21, 2011 2:22 am

    i have found a 160 in one kit and am looking for a pdf possibly for the manual as it was long gone. any help would be greatly appreciated

23. rcgrabbag March 22, 2011 7:09 pm

    Sorry, Randy, I don’t have a 160-in-1. They come up on ebay from time to time for real cheap, so I’d grab one if I were you. Not a bad idea to have a spare kit either!
