John keeps busy and exercises his brain and hands by making microcontroller devices.
He usually makes a nice oak cabinet for them. | |
| This is a window fan which switches on when it gets cooler outside | |
| This is a battery charger for NiMh and gel-cell batteries | |
| This is a home lab data acquisition device | |
| This allows several of my projects to display or record data in a SD Module | |
| This uses a very old parallel keyboard with a new life with PICAXE projects. | |
| This is both an altimeter and a barometer depending on the code. | |
| This is a LED display demonstrating infrared control and real-time clock. | |
| This is a meter with a Picaxe 18X to convert serial data to meter readings. | |
| This is used for measurement and monitoring projects. | I took a very old Nixie clock off the shelf and reworked it with a PICAXE | This uses a cheap clock to time the program and sum the charge increments. |
| A logger with an opto-isolated current input, analog meter, and SD Writer. | |
| A 10 cps mechanical counter with a choice of voltage or contact-closure input. | |
| A PICAXE refurbishes a 40-year old autoranging Volt-Ohmmeter. | |
| A simple dial clock with the hands rotated by two stepping motors. | |
| An automatic switch to save standby power in my entertainment center | |
| A display using 600 mostly green LEDs in a 12 x 50 matrix. | |
| A device to quickly sort transistors according to polarity, pinout, and chemistry | |
| A mobile environmental logger using an 18M2 | |
| A replacement Spa Thermostat using a 14M2 | |
| Picaxe 08M | Picaxe 14M/M2 | Picaxe 18X/M2 | Picaxe 28X1 | Stamp II | No micro |
