http://circuitbendingfool.blogspot.com/ – I scavenged the circuit for this project from a partially motorized ray gun toy. When pressing the trigger a cylindrical component decorated in flames spins within the barrel while a space age ray gun sound emits. I decided to ditch the motor and rehouse this. However the first time on the bench, I thought I had killed it while attempting to rehouse it in a shallow metal enclosure I got for cheap. It just stopped working. At the time I stored it a way labeled in a sandwich bag on my shelf of misfit circuits. As it happens, I was pillaging for parts, came across the bag and decided to power it up. Go figure? It’s working! So, I decided on a design and built it in a recently acquired Tiffany’s jewelry box that I got for a buck at a second hand chain store. The Tiffany’s box has a 20 ohm speaker (purchased at Jameco will-call $1.49each) and a pitch pot with body contacts. Standard 1/4″ output, a clear LED and a toggle switch to power the unit. The tone of the sample heard is very smooth and moves with grace. A wonderful ambient instrument that is slightly unstable. Sometimes…when it crashes…. if it just won’t power back up…..I take it as an opportunity to proceed on to something else.

This was one of my first DIY pedals so I apologize if I come off nervous (I was a little) and I missed some details. I took a page from the RockBand pedals themselves and made my own using a cheap-o pedal from ebay combined with $.59 magnetic reed switches bought from Jameco and an two rare earth magnets stacked. More on this project to come but if you have any suggestions/comments/questions drop me a line at www.destituteagenda.com

I picked up this Coleco Talking Teacher toy for a couple bucks, it was missing the battery compartment cover but otherwise in very good condition. I have had it a little while and did some research before cracking it open (www.experimentalistsanonymous.com) I used bender schematics and will be going back in at a later date to expand upon the gliches and loops. This time around I was amble to install a reset button , speaker cutoff, 8 switches and a 500k pot in need of a trim pot. I ran lines for body contacts but will wait until I can properly explore the circuit. I did cut out some plastic inside to make space but i an thinking of fabricating a plate where the existing handle is to accommodate more components. This is the test video from my bench after first assembly. Thank You Liz at Jameco Electronics. Thank You Colin at experimentalistsanonymous.com.

…a few seconds with the booper, a “JE755 SOUND EXPERIMENTOR BOARD” by Jameco Electronics. It’s a kit from 1987, and it’s the standard noise generating circuitry for pinball games from inception until they began to speak. I got it from my buddy Shell in 1994.

Phil Tang explains his first Jameco recipe, the Door Alarm. The Door Alarm plays a prerecorded sound when you open the door – perfect for an ego-boosting Hail To The Chief!

picked up a catalog from Jameco electronics and the have these IC programmers, i know what the individual parts are and their usage is obvious, but, what do i need before the thing can interface with the memory for example: "37000+ device/48 pin usb stnd alone gang programmer, i understand this model will support all types of usb and flash memory, so the question becomes, what basic circuitry do i need in between the memory ad the programmer? for examples, eprom, eeprom, serial eprom, paged eprom, serial prom, flash eprom, (nor and nand), nvram spld, cpld, epld, mcu, micro controller, sram, and standar logic devices down to 1.5 v.

i will be posting a question in programming on those individual types as well.

What are you trying to do? If you’re trying to program a flash chip, you can plug the flash chip directly into the programmer, assuming the programmer supports the chip. This is normally only useful for developing prototypes and homebrew projects. And even for that, it’s largely obsolete since most homebrew microcontrollers today have their own flash memory.

If you had a serial eeprom you wanted to program, you would drop it in the programmer’s socket, tell the programmer’s software what to put on the EEPROM, push ‘program’, and then remove the programmed EEPROM. But for most applications, you could just program the EEPROM in the final circuit anyway.

Now, microcontrollers with embedded EEPROM may be best programmed in a programmer.
