Maybe Hippy has been distilled into an AI ... we should all be so fortunate.... hopefully he can keep his on/off switch hidden better than Lieutenant Commander Data of Starfleet https://www.startrek.com/database_article/data Live Long and Prosper Hippy

johnlong, looks like you hit a sweet-spot with the i5, 8G RAM, and 250 SSD. I never buy new since retired as PC is no longer tax-deductible. Here in the U.S. I have found some great deals through non-profit refurbishes. My $329 Microsoft Surface Pro 3 was class "A" and my $260 HP Pro X2 was...

If you wish non-contact temperature measurements, here is a link to some old 20X2 code of mine based on work by the late Dr. Peter Anderson: https://cdn.instructables.com/ORIG/FB9/NG2H/GPBD45DS/FB9NG2HGPBD45DS.txt The sensors are available from China through AliExpress for a few dollars each...

This is coming from many years ago when I was building a sock-color-sorter to assist a visually challenged person to mate their socks after wash/dry. As you can tell from Inglewoodpete's response, there is much to consider. Most of the details are contained in #7 response here...

I've used a bunch of methods over the years for pps ... from 555 to RC+FETs, including the surplus battery operated wall clock (wife used to work in a doctor's office, I had a stack of clocks with adverts.) This link has a number of approaches...

This is kind of a cool project, IMO: http://www.esp8266basic.com/ Ray

It has been a long time since I posted in the forum (many may be appreciative of this absence) but I wanted to let you know about an Open Source project that I published that is a refresh of an old PICAXE project, the QBF which I originally posted in the Blogs. Serial comm is one of the big...

Based upon my old post http://www.picaxeforum.co.uk/entry.php?30-Notes-behind-Magic-Morse This example (Will run in Simulator for 28X2) uses both TABLE and EEPROM to store words which are separated by a comma. The word list came from Wikipedia and I have only implemented a few just to have...

Farnell sells the ATmega328P-PU for 2£64. Add a 16MHz xtal and a couple of small load capacitors and you basically have the makings of a program-it-yourself coprocessor at about 3£. Now on Instructables: Scientific-Calculator/ The idea is to create an instruction set that can be "sent" from...

Hall Effect current modules WARNING: I just characterized one of these for a project and while the internal IC conductor is 0.0012 mOhm, the total resistance including the cheap screw-down connectors and the PC foil made the overall resistance more like 0.006+ mOhm. For example, pumping just...

@laserhawk64: PM me with your mailing address in N.C. I will send you by USPS, cost-free to you, an Arduino project board that I have created based on the 328P using the UNO bootloader. The PIX is what you will get... the cable go to a USB serial adapter, so you will need to install the...

Sometimes a design just begs to be simple. Such is true when using a PICAXE for AD when there is just no need to go to the expense of building/buying an external high quality voltage reference for the 10-bit output. With some time on my hands today, I decided to characterize an internal...

A less expensive product is "Tinnit" when you can find it.... http://www.minute-man.com One pint, about $8 U.S.

The path is somewhat complicated and somewhat expensive even at the BAS800 reasonable pricing. Certainly is much more complex than using the PICAXE. As an overview: If you know PICAXE BASIC and are comfortable with your projects and are not hitting a 'glass ceiling' due to speed/performance...

The DC input impedance is in megohms. The circuit output impedance driving the ADC should be no greater than 100K but most will recommend less-than 50K. This is due to the capacitance on the AD that must charge & discharge... so there is an AC impedance concern. EDIT: THE CORRECT PICAXE...
