Hi everyone. Haven`t been here for a while. Had a few health issues. Getting old SUCKS!. Anyway, I am working on a new project. The basic idea is to use a touch pad to set off a beeper when touched. That part is working. the part I need help with is I want to run a program in parallel that if...

Hello everyone. I have been working on a project for years, and have changed the mechanical side of my idea several times, trying to get the simplest way of getting them working with the least amount of parts. I have gone back to the original idea of using stepper motors, because they are now...

Hello. Can anyone tell me if I am on the right track here. I saw a post from a few years back by Jeremy Harris. He talked about being able to detect the high side of a voltage regulator to see if the power has been switched off. The pin it is polling is c.2 on a 14M2. what I am trying to do is...

Hello everyone. I have 2 linear threaded shafts that need to move in unison (or close to) to 6 pre defined positions. what I was thinking of doing is have one Picaxe acting as the master that decides what position they need to go to by sending a serial command to a second picaxe controlling the...

Hello. I have been working on a project to remotely adjust the height of agility poles. I now have some prototypes working. The motors that drive them are twin shaft motors. on one side there is a gearbox geared to turn a 10 turn pot which is used as a voltage divider. the other shaft is geared...

Hello. I intend using 4 Polulu MAX14870 Single Brushed DC Motor Driver Carrier boards to control gun turrets. I will be using a 28X2 chip and I am trying to work out how much current all the components are using. These boards use a pwm pin and a direction pin. I vaguely remember reading that...

Hello. I have a threaded rod with a geared motor attached. I want to send the nut to 4 positions. I was thinking of using ADC to check where the nut is by using a 10K 10 turn potentiometer, that will be geared accordingly, as the shaft needs to make 350 turns from position 1 to position 4. the...

Hello everyone. I am planning out a new project. I want to make a circuit that will check for 2 staples on a book as it is traveling along a chain. We have issues on a couple of older stitching (stapling) machines at work when people working on the back don`t see when a staple is missing. Newer...

Happy new year everyone !! I am converting a kids battery operated nightlight to fade out after a specified time. can anyone see where I have gone wrong in the following code. I am using an 08M2 symbol val = b0 symbol pwmPin = c.2 ;led array symbol led = c.1 ;standby led init...

Hi everyone. I have a floor lamp that uses a 200W halogen bulb and I am thinking of converting it to a few LED arrays. I want to power it with a 12v wall wart. it is metal so I was thinking of making it a touch lamp. When looking into using the touch sensor on an 08M2 I read that it dosen`t...

I have a 12 volt pump to ump rainwater ant near mains pressure. Fortunately for me I purchase 2 of them as I have an issue. There is a microswitch that detects the pressure and cuts out the pump. When the irrigation system is being supplied with rainwater the pump cannot remain on and so...

Hello.I need to create a 37.9kHz pulse for a infrared beam sent to a infrared receiver. Is there a better way than using a 555 timer chip? I need to use 2 or 3 irLEDs to receivers 1 metre away. Thanks. Marz.

Hello. I was wondering if it is possible to communicate between picaxes using TXC1`s and RXB1`s without using holtek modulator/demodulator chips ? It`s not a complicated data transfer that I need. The reciever only has to get a single value between 1 and 3. If it is possible are there any...

Hello. Can anyone tell me if caps C1,C2,and C3 have to be 35V ? It`s just that I have heaps of 16v ones if they are suitable. Thanks. Marz.

Hello. I am trying to get a PCF8583 RTC to send data to an SAA1064. Here is the code: PAUSE 1000 i2cslave $A0, i2cslow, i2cbyte 'Initialize RTC writei2c 0,(%00000100) writei2c 8,(%00000010) ; alarm control registers and clock mode ;bit7 enable alarm...
