I'm taking a look at the new Tracer AN Solar Charge Controller from EPEver. I compare it to the Tracer A series which I've been using for a couple of years and find some nice improvements, and a little issue.
I ordered this super capacitor module so I can test solar charge controllers, chargers and loads quickly. It charges at a high rate and packs a punch if discharged quickly. You'll see it in some ...
Another device on eBay being sold as Maximum Power Point Tracking which I wanted to confirm or debunk. This is a fully featured solar charge controller with load outputs and USB sockets for chargi...
Can you charge lithium Ion cells on a standard lead acid solar charge controller? I've read lots and I'm not entirely sure - so in this video I'm going to start testing it!
In a follow up to part one ( ) I'm looking at breakers. I talk briefly about how they work and then I take look inside an AC breaker, a AC & DC Breaker and a DC only breaker. It turns out they h...
I'm still on the look out for a fully functional lithium solar charge controller. This Anself CMTD-Li310 is another option available from eBay (and others) but will it fit the brief?
After nine months of using the EPEver Tracer A Series MPPT Solar Charge Controller I've a few frequently asked questions and niggles which need to be mentioned.
This Tesla Coil Musical Kit is available on eBay quite cheaply. It's a fairly easy thing to build as well with a low component count. Once it is running it is pretty cool to watch.
The nice thing about the latest tracer series of solar charge controllers from EPSolar / EPEver is the COM port which can be used to configure or monitor the system over RS485 using MODBUS.
After working out cheap ways to charge Li-Ion #18650 batteries I wanted to see if I could find a cheap way to check their capacity. In this video I design and build a simple circuit to do just that...
I've been trying to find the cheapest solar charge controllers the internet can provide for a little while. In previous videos I've been able to recommend some really cheap PWM solar charge contro...
After being given a nice Cree LED torch for Christmas I decided to have a play with Lithium Ion 18650 cells. In this video I go through a few methods to charge them on the cheap - hopefully withou...
Reviews, tests and even building your own! If you want to use solar panels to charge a battery you'll need one! They start simple and can get quite complicated - these videos will help you understand what they do and hopefully which type to buy!
An archive of all my arduino projects. Usually relating to solar charging and batteries but not always. Check out the links in the descriptions for code and schematics where applicable.

A quick update on the Arduino based li-ion 18650 capacity checker circuit. I've updated the code a little and tested the values it derives against the LiitoKala Engineer Lii-300 which I reviewed p...
I wanted to have a play with a constant current DC load - but I don't own one. I'm also impatient and didn't want to wait for one to be delivered. So in this video I set out to create my own.
I've built a second version of the beautifully designed Arduino based solar charge controller by Julian Ilett. This version is hopefully less tricky to solder and uses a few less components - redu...
I'm ready to program all the diyBMS battery modules and the ESP8266 based controller. In this video I go through the process of uploading the code to both.
It's time to do an Arduino project and brush up on my coding. I want to measure current so I've decided to grab an ACS712 5 amp module and have a play.
The third version of this Arduino based PWM solar charge controller came about because of a comment by Julian Ilett on one of my previous videos. Could I reduce the milliamps consumed by the charg...
This is a clock using volt meters to display the time and a Arduino Pro Mini (clone) and a DS1307 RTC module. This project only took a day to build the electronics and hack together the sketch. H...
A tale of code, tests and a fail. This Arduino constant current load project continues. You can find the code on my website: http://admw.uk/iP Please feel free to suggest improvements.
It’s time for a kit build video and I’ve chosen to put together this Dual Power Linear Regukator kit I bought from eBay. It includes some SMD as well as through hole components and uses the XLSemi...
I enjoyed building this ATMega328 based transistor tester. It identifies and tests a wide range of components and displays lots of information and a useful diagram.
In this video I'm playing with my oscilloscope and a few different function generators. I use my iPad, a 555 based module and a XR2206 function generator kit.
This Tesla Coil Musical Kit is available on eBay quite cheaply. It's a fairly easy thing to build as well with a low component count. Once it is running it is pretty cool to watch.
This video starts off well but unfortunately things don't finish off that way. Sometimes electronics is like that - sometimes youtube is like that! Click More for links and the like...
This kit is a simple lead acid battery desulfator which uses the NE555. In this video I build the kit and connect it to a small SLA battery and take a look at what it is doing on the oscilloscope....
Tonight I am building a electronics kit (which I haven't done for ages) and bringing you along with me in this live stream (which I haven't done in ages).
