Hi folks Have not been on here in a while and trying to get my Micro-controller brain restarted. I am building a brass annealing machine. I am using the Picaxe020 to control the stepper motor in the project. I am using 12VDC secondary voltage for the L293D and the ULN2803A. Yes both chips...

They actually have cell towers disguised as cactuses...

I just came accross this and thought it might be an easy way to interface Pic-haxes with Wifi and the real world.( for beginners or us dumb people). Besides having some GPIO it also has RS-232 or RS-485 or SPI It is on my list of things to buy, probably in a couple month...

Could someone tell me the max speed a RFID tag can go by a reader and still be read? Right now I am working on an application where an object is passing over a RFID tag at about 15 km/h Once read, the picaxe will react depending on which tag is read.

Up for grabs:eek:

Has anyone used any of this guys products? http://www.jrhackett.net/AxMateLine.shtml Opinions?

Can anyone tell me what the effective range of these transmitters are? (los) I picked one up years ago fo dirt cheap and have an application where I could use it. Thanks ahead of time.

Well I am doing a little project and need to select a wireless unit that can transmit to 1km I am looking at these to right now but would consider any other suggestions. I like A because most of the work is done on chip. The price is right for B. because they come as a pair. A...

Hey folks a little OT but someone wants to dump the following "old " osciliscopes on me. Dual Triode 6DJ8 ECC88 Telequipment Type D 43 (needs vacuum tube Dual Triode 6DJ8 ECC88) Emco Electronics OSC 10 ST Type 506 Oscilloscope (a big one with modular add-ons listed below) With Type 9A1...

OK so I am spring cleaning and came across one of these DPM 700. http://docs-europe.electrocomponents.com/webdocs/0750/0900766b8075001a.pdf According to the paper work it can be set up to do a number of things. One of which is a frequency meter using a frequency to voltage converter. I have a...

I am starting on my spring cleaning and am about to bin the following. If anyone has any need please contact me. NEC MR52-24US Signal relay contacts rated at 1A @ 120VAC 2A @ 30VDC DPDT Motorola MBR6045 60 amp Schottky Rectifier 40 V added: Well Haku MINE are all new, so there! I...

There sure are a lot of posts relating to serial communication issues. Any chance Rev Ed could produce a more indepth data sheet to go thru all the ways of transmitting data in more detail? I am sure that a good 10% of new posts would disapear. Maybe even include a trouble shooting guide...

And can any of this be used with a pic and what applications would they be used for. The only useful one I think would be the RAM one. i have 1. CYC7C4261 16Kx9 Deep sync FIFO http://www.cypress.com/?docID=24690 2 CY7C006-25JC 32K/16K x 8, 16K x 9 Dual-Port Static RAM...

My search failed..wooohoooo I have been trying to find the schematic for getting two Picaxes connected thru serial. I know I have seen it on here before but search just isn't helping me today. Thanks ahead of time. Edit Found this http://letsmakerobots.com/node/3548 but I want bi directional

Just got my order of 08M's and 28X2's..... And they are all the latest releases. Now to go and learn about pic communication.
