content: Has there been a post about this or did it get missed?Ben converts a See and Say to spout Dave Jones quotes!Ben works on his Dave Jones of the EEVBlog impression and gets the idea to gather a bunch of Dave's sound bites and make a custom sound board by hacking a child's toy. Ben opens up the toy and gets to work on replacing the silly animal sounds with phrases like "pure engineering evil," "amps blow up your circuit," and more!Awesome!https://www.youtube.com/watch?v=wYo4lOuD_-Y&feature=youtu.be

content: It's a fun hack, although a few things could probably be improved on:- PCB traces, use them instead of fiddling with the split ribbon cable- odd choice of MCU (is that a DIP40?)- what's with the aversion to SMD?I'd probably use a QFN 8051 and fit everything on one PCB.

content: Quote from: han on May 19, 2014, 01:58:38 pmExactly. I would have used a DIP package in veroboard if available.And I would have just hacked into the existing PCB. But Ben obviously wanted a tie-in with a future episode on PCB making, so that makes sense.

content: I remember those from when I was a kid, but back then they had a small phonograph record inside. My favorite was to select "CAT" and it would say "Listen to the cat..." and then I'd spin the arrow really fast with my fingers and it would sound like a cat fight. I thought it was the funniest thing ever (well when I was 5)

content: Paraphrased:"ARM Cortex processors are awesome, and can use free development tools and have great performance""So we're going to use a Propeller processor in this project"I've always wondered, is Propeller entirely in-house developed or is it based on something else, and does anyone use it outside of the hobby market?

content: Ok, I'm going to play armchair quarterback here (probably a phrase only Americans would understand) and come up with a few changes. I have fun trying to figure out ways to do something so this is not any kind of poo-pooing on the design.I like the "Hi!" on power on but by doing that, it does require the unit to be powered on when used.I'd like to think there would have been a way to only power the board when the lever was pulled.Perhaps 2 switches, when you pull down it charges a capacitor from the batteries and when you let go, it plays the audio file while running off the charge. Of course, it may not be possible to charge a capacitor that fast that would run the board, so it may be out as an option.So another option, pulling down hits a switch powers the MCU and the MCU pulls one pin high and waits for the lever to hit the top. The high pin is connected to a transistor that keeps the unit powered. When the audio is done, the pin goes low and the device turns itself off.Actually you could probably wire the "Hi!" switch into that somehow. The main switch powers it on, but the mcu checks if the switch has turned it on but it hasn't been activated by the lever and just says Hi and then turns off.I guess the key there would be figuring out how to make the power switch feel like a slider but act like a momentary contact switch.Bonus: See if you could possibly hack one of those hand crank flashlights in so that pulling the lever spins the small generator.

content: Yes, a switch at the top of the lever would activate whenever the level was pulled down and that could power-up the circuit for some pre-determined time period.Clearly, the OEM design detected any of the button presses to "wake-up" the circuit. But they had the benefit of an ASIC to implement their design.
