I impulsed a sleeve of programmed chips, with stickers covering what they were. They are a Motorola XC68HC705C9CP microcontroller in a 40-pin DIP package. http://www.elnec.com/device/Motorola/MC68HC705C9+%5BPLCC44%5D/ ^Any one know of a dedicated site...
OK - has anyone any idea if you can buy those anywhere? Or do you have to make them yourself?http://www.hizook.com/blog/2010/12/07/electropermanent-magnets-programmable-magnets-zero-static-power-consumption-enable-s
I'm pretty sure I've done this dance before. Anyways... I'm trying to count pulses off a telephone dial as BCD. Right now, the circuit I've got goes straight to ten and latches. It doesn't count. I started with this circuit......and adapted it (redrew,...
I'm trying to upload a background image to my private project. It shows the loading bar goes to 100%, then displays "Something is wrong, please try again". It's a 556KB jpeg, 1200px x 675px. Tried on Safari and Chrome.How to fix this?Edit:...
What's the absolute cheapest possible programmable wifi camera with low power sleep? I want to monitor my water use by taking remote pictures of the meter. It's in a place where anything of value will be stolen. Also, no place for wires (sidewalk) so...
2 years ago when I started my hexapod, I didn't have to much cash to spend, so i bought 12 of these https://hobbyking.com/en_us/turnigytm-tgy-s901d-ds-mg-robot-servo-13kg-0-14sec-58g.html from hobbyking. When I got them, one broke in a year,...
I'm on my wit's end, so I thought maybe I will ask for help here. I'm trying to get to work an ILI9340-based LCD display. One of the cheap ones, not the ones from Adafruit. It looks like this:I tried to use both the ILI9340...
Working on my TTL CPU project https://hackaday.io/project/162659-8-bit-breadboard-cpu . I'm working on wiring up the first block (the XY register). I have 8 x 8 bit bus drivers for the register. I started using 74ACT241's for...
I was wondering if anyone can help me. Since, I'm not smart and I don't know a lot it probably is logically fallacious.Anyway, I need to find an unknown factorial. This factorial is suppose to be our quickest (polynomial time) solution to our "non-polynomial...
I'm working on a project for a USB HID device. Internally it has any number of 5V IC's. I really, *really* would like to use a Teensy 3.5 for this ... but they're sold out everywhere. Please, if you've moved on to Teensy 4.x but still have one lying...

From Mike Rankin's blog:https://0miker0.wordpress.com/2016/10/12/samd21-giveaway/What:I’d like to give away one SAMD21 logger/sensor board to someone, wherever in the world you are.Why:I’m a hardware guy, not a programmer. I’ve had fun designing this...
I've never used a DSP chip before, but I want to process some digital audio (I2S). So I'm looking for a chip that's easy to work with (i.e. has good tutorials & tools) for my #Modular Open-Source AV Receiver.Processing requirements are basic - delays,...
NOT THE ESP32. I don't have those and I don't want them. Yet.I *do* have a couple ESP-12E boards. I don't have much (okay, any) experience with them yet, but I cant imagine an 80MHz almost-ARM-ish microcontroller would let its butt be kicked by...
