For my Volume Control project I would like to use infrared but not in the usual sense with sending codes using remote control unit. What I would like to do is establish a serial connection with the picaxe but instead of using RF modules do it using IR LED and IR receiver. I did some googling and...

I stumbled on this IC today, PT2258, here is the datasheet . Curious if anyone has used it. Looks to be easily controllable with the picaxe. I ordered a few chips to try. I doubt it's high fidelity but am hoping to be surprised. If it works well it will be perfect for my application, I'm working...

Gents, I've been shopping for pc board makers and it's gotten expensive since I last ordered boards back in 2015. I used a couple places back then, one was dirtypcbs.com, they did a nice job but the shipping is more expensive than the boards. Any suggestions, are there any inexpensive US based...

My Technics linear tracking turntable from the late 80's needed a new belt, the old one worked but made slight noise and i also wanted to check the lubrication. took a little doing to take it apart but once open everything was accessible. Looking at it I got a hankering to make a linear tracking...

I'm considering a 3D printer purchase, nothing fancy. making small parts, gears and such, small enclosures for picaxe projects. I don't want to spend much more than $300. Any suggestions? Which 3d printer are the picaxe forum denizens using? Thanks in advance.

Are there custom wizard creation tools available. For instance, I am playing with the AXE023 motor control board. Works really well but I'd like to have a wizard of sorts that would write the downloadable program from simple instructions i.e. go forward for 1 second, turn left, go forward and so...

I seldom use the sound generating picaxe feature, now that I tried it I like it a lot. I'm using one of these, it works but is very shrill sounding, i think it's meant as a stand alone beeper. I'd like to get something a little better, maybe add a transistor to drive it, appreciate any...

Looks like the microchip famine is passing, I just got a big shipment of 08M2 chips, albeit they are labeled 12F1840, I have to be careful not to confuse them with my small cache of non picaxe types. My experimentation with basic compilers is winding down, way too buggy and documentation is poor...

I'm experimenting with a Nextion display picaxe 20x2 combination. My goal is to have the nextion as a portable serial monitor for other projects. The Nextion is a 5V device but it does work with a single LiPo battery, albeit, not for long. Anyone on the forum run the nextion on a single LiPo...

Hello, I have been using a combination of picaxe and raspberry pi nano for a while now, it works great but for one major issue. Raspberry Pi uses an SD card as a hard drive and the SD card fails in a little less than a year. It's not an issue for me I just burn a backup of the OS and all is well...

I'll be ordering the VL53LOX TOF module, from little I've read about the sensor it's capable of detecting a single photon. I'm curious if anyone knows how to access just the detector portion of the module without using the laser portion. I'm thinking with a Scintillator screen the module could...

I made a simple water level detector using a transistor and a pair of wires, transistor turns on and triggers a picaxe. All works well. The question i have is about the wire. I used some tinned copper wire, looks silverish, it does not oxidize in the air but after sitting near water and being...

I usually use EEPROM memory to store array values but decided to give the scratchpad a whirl. I use memory locations starting at 28 up to 128 and just do a for next loop to see what's in the locations, i run the loop before my program begins and every location has a zero in it, then, it hits my...

Hello, I have many picaxe chips collecting all sort of data and displaying the data on a web server run on a Pi or a PC. I would like to also display graphs, now, I use thingspeak for graphs but would like to go to a local server. There are dizzying amount of ways to serve graphical pages, I...

For Australian forum members, Hayabusa2 will be dropping off it's capsule December 6th here is a link to help spot the Fireball. I wonder if there is a way to detect it using a picaxe.

Hello, would it be possible to have a picaxe and a raspberry pi sharing an EEPROM. My thinking is to have a picaxe write data to an external EEPROM and then have a raspberry pi retrieve that data at will. I realize they can't both be active at the same time so i would have to have handshaking...

I'd like to use the digital to analog function of an 18M2 chip, is it safe to use an NPN transistor to buffer the output, the suggestion is for an op-amp but I was hoping to use less space. Also, is the voltage coming out from the DAC steady or will it vary depending on how busy the chip is...

I'm sure I have seen this question posted before but am having difficulties finding it on the forum. Every so often I like to finish a project by installing it in an enclosure, lately i have been making front panels from thick aluminium, comes out very nice, I would like to label the switches...

I'm making an input selector for an amplifier. I want to control it with a picaxe, it will have an Infrared remote control and also a single button that will go through 4 choices. The IR command is blocking, what would be the best way to sense for switch closure, should I go with an interrupt or...

Hello, I bought one of these for my turntable, and neglected to notice that it's a 50 Hz model and I need a 60 Hz. I don't mind that it's 50 Hz I rather prefer a portable light source. I need to order some high intensity LEDs, would a white LED be better or should I go with red or some other...
