Desk of Ladyada - Mailbag of Retro Goodness
42This week at my desk we're going to look at some funky retro goodies we received. First up is the 8088 DOSBOX which is a totally weird 8086-based laptop. Let's take a trip back 20 years ago to 1987 (that was 20 years ago right?) to a time when we only needed 640KB of RAM and 16 colors to have a good time. We'll play some tetris (https://www.myabandonware.com/game/tetris-dj#download) and maybe take a look inside. Then we'll also check out a McDonalds McNugget Tetris game (https://tetris.wiki/Tetris_(McDonald%27s)) given away in China for the 40th anniversary of the chicket mcnugget. So I guess its more like Desk of Tetrisada tonight!
The Great Search - Disc Piezo Buzzer Element
https://www.digikey.com/short/dtbmq7jm
This week on the Great Search we're taking apart a McDonalds McNugget Tetris game (https://tetris.wiki/Tetris_(McDonald%27s)) given away in China for the 40th anniversary of the chicket mcnugget. Unsurprisingly its an epoxy blob'd chip that does just about everything! For the background music, a disc piezo is used to make the beeps. We've covered magnetic buzzers before (https://blog.adafruit.com/2020/11/24/the-great-search-piezo-and-magnetic-buzzers-thegreatsearch-digikey-digikey-adafruit/) on the Great Search which we use on some of our design for SMT tone-making. At a 500K build, budget is going to be the most important, so instead we can go for a ultra low cost piezo disc! Let's take a look at what is available at DigiKey and the differences between magnetic and piezo buzzers.
