circuit bent vtech little smart alphabet desk

this is how circuit bending works right here. Be patient-- there are some nifty sounds in this clip.

1:57 says f*ck? haha

0__0  how did i not notice that before

[jimtobias]

this is great! i just found one of these in a thrift store yesterday. i'm not sure i'm seeing what you've done. it looks like you have one clip shorting the 'repeat' button on the small pcb at top right, and another that you 'scrape' along the sensitive points on the big pcb. where is the other end of that clip -- ground? i just don't want to fry this beauty.

thanks -- i'm a subscriber forevah!

[RobotTickleFight]

hey thanks! What happened was I couldn't get any one point to consistently repeat a sound, so I gave in to the anarchy of bending and just started going at the board, so I could at least hear what sounds the toy is capable of.

[RobotTickleFight]

anyway, the other end of that clip is attached to ground. The other clip in the corner of the screen is actually just acting as the power switch while the toy is taken apart.

If you're worried about frying something, what you can do-- and what I should have done if I had been more patient at the time-- is put a just like a 10 ohm resistor in line with your test lead so that there's some safety buffer.

awesome. subscribed.

I just tried a bend on a Vtech Write and Learn...I thought it would be REALLy Cool cause it makes different sounds as you write on the pad!...When I took it apart the board was SO SMALL (about 1/2 the size of this one)...I could BARELY touch the integrated points together much less solder to them!!..Then I finally did get some cool glitches for a few minutes...then a small spark and NOTHING!...A 10ohm resistor inline with the test lead you say?...the toy may have been really new..

This is great, but I'm so pissed. I just bought one of these today, and after two second of trying to bend it, it gave up the ghost. I have test probes that I soldered a 1M pot between so I can vary the resistance, and still just touching two random points killed it... I'm still mourning.

@geboy5 it said fucker

2:09 - 2:10 WTF? Lol!

@marsonic - using only a 10ohm resistor is not advisable. I would recommend using 1 to 10k ohm. Better start out with too much resistance and if it does'n work, gradually swap it for smaller ratings, than fry things. Or use a linear sliding potentiometer between two alligator clip/probe wires, it's a nice probing tool for bends. Sliding pots give you better visual indication of actual active resistance than rotary pots. Attach it to something heavy enough to use it with one hand while probing

Haaaa! You made the thing go nuts. that rules.

Hi robot ticcle fight this is michael sharing an acount with funtyron. I played with one of these when i was a kid but it wasn't bent. I hope you wern't trying to kill the voice because that glitch reminded me of a furby diing. can the bend be reversed so that a kid could use it on it's normal setting?
