The Totem Mini Lab is a kit to build an all-in-one lab setup. Built around Totem's take on an Arduino Uno, it features a companion lab board which add many useful tools, and is to your prototyping and development.
The kit comes with the following parts (as listed on the Totem site:
- TotemDuino – our improved version of Arduino UNO;
- LabBoard – a capable experimentation and measuring platform;
- 34-pin flat cable – use it to connect TotemDuino and LabBoard together;
- Collection of Totem construction parts – for building Totem workbench;
- Voltage adapter – to power laboratory from the mains;
- Breadboards CYB-120 (2 units) – to extend your experimentation area;
- Breadboard cables – Jump wire 20 cm x 40 pcs. U Shape Breadboard Jumper Cable Kit, 140 pcs;
- Building instructions – suggested use of Totem parts for building a workbench where everything neatly mounts together;
- Standard USB 2.0 Mini Cable 1m (A-male to mini-male).
I thoroughly enjoyed putting this kit together. Having recently assembled the little 2WD Car Kit from Totem I found building this an absolute joy. The included parts sheet for reference came in very handy for organising and measuring out parts and accompanied the printed build guide brilliantly. Some of the images in the book can be a little unclear as to where the nut inserts go, but once you have done the first few steps it becomes clear what is meant. The printed guide was a much better reference tool than using the online guide that the 2WD Car Kit requires to use, but I feel that is because I used my phone to view it. Still, the high quality printed document is a nice addition to the kit.
The build itself was fairly straight forward using the included driver (the only tool needed). I did find a few of the screw angles were a bit tight for a fat fingered fellow such as myself when assembling the frame, but the driver does have a wide angle of use to help it still do the job at an angle, plus the order you attach the brackets can also make it easier.
Still, all in all I had a great time assembling this, and look forward to using it :-)
Software & Usability
***Software review to follow***
It is possibly to add add-on modules to the lab it further increase its value as a prototyping and development lab.
In the coming weeks I will be putting the add-on modules through their paces along with the software aspect of this kit. I'm really looking forward to it!
All in all I think this kit is absolutely fantastic. As someone without a dedicated workspace for prototyping and development I was really excited at the prospect of an all-in-one system that could improve my workflow and also tidy up the stack of boxes full of random microcontrollers, components and all kinds.
Once I have received the add on modules I am going to be moving my development for my current projects ( #DIY SamplePad Controller and #Digibone ) exclusively to this lab and will then update the software and usability section of this review. I am also keen to test how this would work in conjunction with a raspberry Pi w/touchscreen setup. Or even use the Maker Kit to build a Pi cluster chassis to add to this build.
I'm really hoping to see Totem continue developing add-on boards for this lab; it's a great form factor, and increasing the options available will really increase it's appeal as a useful tool for makers.
One in particular I'd love to see is a Network-based add-on, build around an ESP32 to add Wifi, Bluetooth and perhaps ethernet ports for IoT development. I'd also love to see some further TotemDuinos developed, using perhaps the Mega as a base rather than the Uno, maybe even including an ESP32 on it rather than as a separate module.
Anyway, I'm really excited by this lab and look forward to seeing where the future takes it!
