I have a robot kit that is currently controlled by a Romeo BLE from DFRobot, which has built-in motor drivers. I am looking to switch from this board to a Raspberry Pi. I looked to get some 5 amp motor drivers to use and was surprised by the price....
I'm trying to get the ESP8089 driver working to use an ESP-12F as a wifi module for an older raspberry pi (like this project: https://hackaday.io/project/8678-rpi-wifi).I've got the ESP-12F wired up and the kernel module built, but the module crashes...
Instructions here --> https://pastebin.com/cp9hWWCkThis is in case the tip line ignores me (which is quite likely -- I'm not one of the "cool" kids...). I just want to get this out there, because it works... I compiled these instructions and...
HelloSo i have a dasung paperlike monitor that connects via usb only to a laptop, then i need to install driver and it will work as an external e-ink monitor.I also have another dasung monitor model that connects via USB + HDMI, and need no...
You’ve no doubt heard the annoying “ding” sound when you forget to buckle your seat belt. Well GM is taking things to a whole new level with its “Teen Driver” feature which is set to debut in the 2016 Chevrolet Malibu. Parents...
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...
Something that bothers me for quite a while now: why is there no small / cheap hardware emulator for BLDC motors? I've seen contraptions where two motors are coupled and one is actively driven whereas the other just has a resistive load hooked up to...
I am developing a BLDC controller. The original motor that I was given seems to be causing problems so I want to ask the community what kinds of motors they would want to use with OpenBLDC. I am thinking of just buying one of the outrunners 3-phase motors...
If you google for Raspberry Pi hostapd, the majority of the tutorials all have the exact same advice: 1. Get an RTL8188CUS based wifi dongle 2. Download or build a custom, Realtek proprietary, modified copy of hostapd from the pleistocene. 3. Set it...
Looking for some pointers as I have been trying to get a BU-353 GPS working with an LPC1768 MCU (speecfically the mbed dev board) using this library https://developer.mbed.org/users/va009039/code/GPSUSBHost/. I can get it communicating but...
So I'm working on a e-ink picture frame for my parents. The LCD ones you can always tell it's an LCD. E-ink has a much more real printed picture feel to it. My current plans I'm musing over are: buy a used kindle DX ($120-150 on ebay) stuff it into...
I'm thinking of re-doing the electronics to an old shift-register based 8x8x8 LED cube (uses 5v LEDs). I want to instead do fast pwm in hardware.Unfortunately its built with the layers being common anode. So I need 64 individual pwm outputs which...
The bi-color matrices I ordered turned out to be common-anode ones, and not common-cathode as I expected. This means that I can't drive them with the HT16K33 chip as I planned, as it only has 8 cathode pins. I can't even use two such chips to drive the...
