I’m just making notes of some resources I’ve researched or found useful.
I’m based in Stellenbosch, South Africa, so these have a slant towards the shops and groups close by.
I include my opinions and impressions, including things I heard from others. In general, the listing indicates a ranking, first ones listed are better, but not always.
This list is not complete by any means. If you want to add anything, let me know via email or on the Arduino Cape Town group on Facebook.
I’m excluding the local hardware stores and the chains like Builders Warehouse, Brights, Mica, Timbercity and Penny Pinchers.
Being in South Africa, we pay a lot to get items from overseas and the delivery is long and unpredictable. This is just a reality. Even shipping in South Africa is sometimes expensive. So, in general, I try the following:
- Find a local shop with the items or good equivalent
- Find an SA supplier with non-outrageous pricing
- Chinese supplier. This is usually a long wait, but cheap and shipping costs are very low. There are some issues recently with importing: If you import more than a few (3) packages a year, you have to register as an importer.
- US/European supplier with an SA distributor. Probably about same pricing as importing, but hopefully faster.
- US/European supplier with shipping to SA. Usually require a minimum order size to make it worthwhile.
If you want to ask for help, the best place is probably Arduino Cape Town.
Electronics guides, follow-along projects, 3D models etc:
or just Google around.
There are a few makerspaces in the area:
- Maker Station in Woodstock. Awesome place, and very much involved in the community
Makerspaces in other areas:
- House4Hack in Centurion
- UP Makerspace in Pretoria
- The Makerspace in Durban
- Werkspace in PE
- TMG Makerspace in Jhb
I know of a few meetups in the area:
- Communica in Paarden Eiland has a full stock of Arduino and hobby based components. Their website gives you an idea of what’s available, but it is NOT complete. Phone them, the people are friendly and know their stuff. Their showroom is worth a visit just to see some of the range of things they have.
- Netram close to Century City has a lot of electronics and 3D printing stuff. Sometimes a bit disorganised, but they have some useful stuff.
- Micro Robotics in Technopark Stellenbosch

I’ve needed some very specific items before, here’s where I found them:
- Lazy Susan bearing: Dawn Kitchen Fittings in Barlinka road, Saxenburg, Blackheath, had one back in 2013. Roco fittings is apparently a division of Dawn, so they might have. Google the address and links.
- Skateboard Bearings: Literally any skateboard shop will have 608 size bearings, which are a nice size (22x7mm, with an 8mm hole)
- Music shops have guitar strings (great as elements for hot wire cutters), and might have guitar string tensioners, which are good for all kinds of precision tensioning
- Spectre/Dyneema UHMWPE fishing line (very strong, almost no stretch) can be found at good fishing shops.
- Large bearing balls (25mm): Bearing Man Group is all over SA, I got these loose from their branch in Gants Park in Somerset West.
- Half-silvered glass for infinity mirrors: Go to car window tinting places. They have a silvered plastic film that you can mount on glass.
- Wilec sells magnet wire in larger quantities, but so much cheaper that I’d rather buy 2kg from them than 100g from a hobby vendor (R425 for 2.2kg or 0.2mm magnet wire, 2017/10/17)
- Eloff Transformers looks like they could be good for bulk coil winding.
- Masque FX Warehouse in Gardens looks interesting (Special effects makeup and prosthetics)
- Stencil-Art has art supplies.
- Isoboard for insulation foam
- Xanita in Blackheath makes really strong corrugated cardboad sheets. Nice stuff for displays etc.
- Merrypak has cheap plastic ziplock bags, tins and assorted things useful for projects.
- Baking/Catering supply stores are interesting. Some sell brown teflon sheets, which are awesome as project surfaces. No glue or paint will stick to it, and it can handle hot glue right on the sheet:
- Munaaz Catering Equipment in Woodstock
- The Baking Tin in Ottery
- Cab Foods has outlets all over, including in Somerset West, Brackenfell and Worcester.
- Comet Aviation Supplies for aviation items and good stainless steel wire.
- Palram for Palfoam foamed PVC, interesting lightweight sheet material
- Silica Gel SA does silica gel dessicants, if you have need for something like that.
Scavenging and offcuts
Of course, scavenging parts is useful if you need items immediately. Electronics scavenging is mostly not worth it, but there are some interesting things you can get from old machinery.
A lot of maker projects don’t need a lot of material, so looking through the scrap bins at a local business could be useful.
- Old hard drives have crazy strong magnets in them. I’ve used these as clamps, mounting points, etc. Computer shops might have some of those lying around.
- Inkjet printers have great 8mm hard ground shafts, about 400mm long. I’ve walked into printer repair shops and walked out with enough broken printers to get shafts to build a 3D printer.
- Network cable is a great source of long, thin twisted wire pairs for communications. Be aware that solid core wire might not handle repeated movement well.
- Sign shops might have some scrap plastic sheeting.
- Metal laser shops often have lots of scrap.
Other interesting places:
- Wikipedia’s list of manufacturing processes gives an overview of ways to manufacture things.
- Dale also has lots of links.
- Pajamas and Jam is a really nice coffee/antiques shop in a warehouse attached to a scrapyard in Gants Park, Somerset West. Lots of old tools, an anvil collection, and possibly some parts for antique/steampunk projects.
- Truth Coffee in Buitenkant street in Cape Town is a feast for the eyes, and they have some pretty good coffee…
