Complete Bloc-Tronic manual

Love Tester ProjectFor those of you who are interested I have now posted the complete Bloc-Troic manual in my gallery!

From cover to cover (well, not really, the back cover was blank so I didn’t scan it.) the manual contains 163 electronic experiments. Each experiment illustrates the block layout for the kit and also includes a standard schematic for those who want to breadboard or permanently build any of the projects.

The experiments span from a simple conductor/insulator tester to a sound level meter to a basic radio with microphone mixing. While the Bloc-Tronic set was designed for children completing every, or even most projects in this book would be quite an accomplishment!

Unfortunately I have not transcribed the text from these pages to make them searchable. Perhaps someday I’ll get around to that, or better yet, maybe some fan of the set will volunteer to do part or all of them for me. (It took me a year to even get the images up, so don’t hold your breath on my account.)

If you’re having trouble making out something in the images notice that you can switch to a high-res version. The shadows in the image are the experiment on the back of each page bleeding through which should give you an idea of the quality of paper used in this manual. I have made it available because it seems to be orphaned. It is no longer made or distributed, the company named on the manual and box seems to have disappeared and there isn’t a copyright to be found anywhere in the materials.

I hope some others can find this useful with either the set or for building experiments on a breadboard.

Bloc-Tronic electronic kit manual

Bloc-Tronic ManualI have written about my Bloc-Tronic electronics kit before. My original article on the kit has garnered several comments asking if I could scan and upload the manual.

I’ve finally uploaded the first 100 pages to my images site! The entire manual is around 180 pages, so this is most of it and I hope to get the rest up sometime soon.

If you are lucky enough to have a Bloc-Tronic kit without manual, hopefully this manual will be of use. Also, since the experiments include schematics in addition to the block layout they could be done on a standard breadboard or even permanently assembled from components.

The experiments start off simple and get progressively more complicated. There’s everything from a volt meter to a radio receiver.

USB Humping Dog

Yes, proving that just because you can doesn’t mean you should someone went out of their way to come up with this little novelty:

Yes, for $20 for the single or $55 for a set of three you too can put USB power to use in a way you never imagined with your very own USB powered humping dog.

TSA List of Permitted and Prohibited Items

I’m getting ready to travel for business next week. Since I haven’t flown in about a year I figured I’d check the TSA website to see what I can and can’t carry on.

Well, the list is more detailed than I would have expected. It seems if I want to carry-on toothpaste it still needs to be in a 3 oz or less container, but at least I can carry on my Optimus Prime!

TSA List

Thank goodness. I hate to think of the little guy shivering in the cargo hold.

USB Missile Launcher – Hands On Review

USB Missile LauncherWhat do you get for the geek who has everything? Of course! Their very own USB Missile Launcher! But is it really worth it? Yes! Read on and find out why.

Overall Rating: 9 out of 10


  • Roughly 12 foot range
  • Accurate within a foot or two even at range
  • 180 degree pan
  • Limited but reasonable tilt control (about 30 degrees above to five degrees below level)
  • Fires three darts one at a time
  • Soft foam darts are safe around the office
  • High quality molded plastic construction
  • Free Mac software better than included PC software


  • Couple second delay between clicking “Fire” and actual launch
  • Batteries required (3xAA)
  • Included software does not allow for simultaneous pan and tilt (movign diagonally)


Launcher in boxThe USB Missile Launcher came to me from the folks at who have quite a line of toys and gadgets appropriate for the office. They sell the USB Missile Launcher for $55 which I consider a fair price for a toy this cool.

It comes quite attractively packed… the type of thing that you wouldn’t be able to keep on shelves in the right locations. It would make the perfect trade-show giveaway for the same reasons. Have a stack of three or four of these at your booth and you’ll get some attention (hell, at the price just give away a dozen.)

The USB Missile Launcher was equally impressive out of the box. The unit quickly pans through 180 degrees and tilts about 35 degrees. The PC software that ships with the unit is limited to only moving in one direction at a time, while the free Mac software allows movement in two directions.

You can fire one missile at a time and the missiles shoot out with surprising speed, propelled by a small spring which is compressed when you load the missiles. Both software versions suffer from a second or two delay when firing. I have a feeling this is a limitation of the device, but it’s the only major flaw in what is otherwise a great piece of office artillery.

The launcher is solidly constructed and the darts have held up well for me. There is nothing with the unit or on the KlearGear site about replacement missiles, but I’m sure if there’s a demand they’ll become available.


This is a great office toy and would be a great gift idea for anyone who regularly engages in cubicle warfare. At a cost of $55 from the USB Missile Launcher is one of the most unique toys you could get someone this holiday season.

I had hoped to get a couple videos up of the launcher but haven’t been able to get any I’m happy with. Perhaps it’s time for a new digital camera.

Thanks to the folks at for giving me the chance to evaluate the USB Missile Launcher.
